EuraPra® Wonpro II  –  R4 Universal Sockets


Two Major Defects with the 25 years old obsolete R4,  R4T:

1.     They have "Defective" Safety Shutters ─ Half Inside the Socket, Half Outside the Socket

2.     All Schuko/German/French etc. plugs lose Ground Connection when inserted into this old R4, R4T

3.     R4-GF / R4T-GF without Safety Shutters can only take 4 grounded plugs, not universal at all.

4.   The R4TS on the right picture is a FAKE ─ Does NOT meet Safety Shutter requirements.

      This design does not have a "locking mechanism". A single pole can open either side of the power socket.

      There is a "Patched Solution" out there. It requires an additional "on/off" switch to lock or unlock the Safety Shutters.

      This is NOT how a Safety Shutters should work. Just compare to how the British engineer designed their UK socket.

      We drove this design. We are the ones with strange creative thinking. We dropped it, just didn't like the on/off switch.

How the Defects are Corrected in the Next Generation EuraPra®Wonpro II eR4, eR4T:

1.     SLIDE IN, not SLIDE OUT 

      Reversed the Direction the Safety Shutters are sliding in order to make room for a plug.

      This very Creative Idea takes a lot of engineering hard work to implement ─ a Complete Redesign!

2.     Connect to the Bottom, not the Side of Schuko plug Ground Metal.

      Again, Creative Thinking, the ability to look at a problem from a different perspective is the key here.

      A lot of engineering hard work to keep these two Schuko metal pieces IN POSITION.

      The Safety Shutters push the Schuko plug toward the Schuko Ground metal and produce very TIGHT CONNECTION.

      The two Schuko Metal pieces can slide open horizontally to allow US, Denmark, Israel Ground Pins to get in.

      This is a very creative "non-blocking" innovation because it blocks no plug and allows eR4, eR4T to stay truly "universal".

3.     Use the Highest Quality Materials.

      We have new 20 years PATENTS, we don't need to cut materials to compete with "generic" low quality, low price R4 sockets.



EuraPra® Wonpro II  –   Universal Power Strips

  Why IEC Temperature Rise Test and Burn Test are so Important?


The above photo pictures are found on Google images:

1.     The first one shows a power strip MELTED - This is why IEC 60884 Temperature Rise Test is so important

2.     The second one show a power strip ON FIRE - This is why our Burn Test  is so important





  4G Universal Power Strip Enhancements

WES.eA Series ("eA Series"the most Compact design, 1.6" socket spacing, Can't take UK plug side by side)

1.     All of our new universal power strips will be CE certified and RoHS 2 certified.

2.     Update to use the new WAbc universal socket:

      'b':  It will take Brazil's new Type N BR-2 and BR-3 plugs

'c':  Correct the N-L reversal problem with the Swiss plug ("CH" is the two character country code for Switzerland)

3.     Applied the new Schuko Ground Support to the new eA series

      This is our latest and greatest Innovation (20 years innovation patent pending)

      Our universal power strips are the only one will not lose Schuko grounding when used with Schuko electrical devices.

4.     Replaced the R4 sockets with an Open Circuits

      Build a power strip the right way, not the "lazy" way.

5.     Applied the new Safety Shutters

      This is our latest and greatest Innovation (20 years innovation patent pending.

      The new eA power strips now meet the European Safety standards.

      Fixed the very annoying "safety shutters" problem for “US Flat-End” plug

6.     Add an built-in IC Board - the one and only universal power strip to use an IC Board

      Our universal power strips are the only one with built-in IC board to protect MOV surge protection and to support LED lights indicators.

7.     Add a Ground LED light, a MOV LED light - now it is an Intelligent universal power strip!

      Enable you to tell if the MOV is still working (not burned out by a surge yet). If the MOV surge protection is burned out, you have the option to decide to continue to use this power strip or to throw them away - in the old model, you have no way to tell if the MOV is burned out or not.

8.     Increase MOV surge protection from 450 Joules to 1,050 Joules - on IC Board

      We are the pioneer to add MOV surge protection to universal power strips - and we do it the right way!

      To prevent "MOV Explosion", we have an extra fuse on our IC Board to protect our MOVs.

      Adding MOV to the open circuit, not on an IC Board, actually add more Hazard to a power strip - "MOV Explosion" can start a big fire.

9.     Double-Pole On/Off RESET button, increase Thermal Surge Protection from 2,000 Watts to 4,000 Watts

      Double-Pole switch can completely cut off the electrical current when it is turned off. Single-Pole switch cannot!

      This effectively upgrades our surge protection rating to 5,050 Joules (4,000 joules in CBS + 1,050 joules in MOV).

10.  Add 4-oulet eA4 and 5-outlet eA5 to complete this series

      This was a great decision. Warner Bros loved our 4-outlet eA4 model, they bought thousands of eA4 with various country specific cords right after they saw our pre-production samples. Clearly there is a large demand for 4-outlet and 5-outlet eA power strips.

11.  Use the highest quality material

      Upgrade the plastic to the highest quality Phosphorus Copper to offer the highest conductivity.

      Upgrade the plastic to the highest quality Non-Flaming "PC", with twice the "impact strength" of "ABS". The report says "PC" is better than "ABS" in every aspect except pricing - it is true that "PC" material cost a lot more!


WES.eT Series("eT Series"the UK Friendly design, 2.0" socket spacing, Can take UK plug side by side):

1.     eT series have ALL the Enhancements implemented on eA series!

2.     Applied the new Safety Shutters to the eT series

      The old BIG safety shutter dictated the old T series of power strips and ALL "Generic" Universal Power Strips to be very WIDE, very BIG: at least 65 mm or 2.56 inches. With this completely redesigned new Safety Shutters, the width of the new eT series of power strips are only 54 mm or  2.126 inches, close to 20% of Reduction in Width. That is, eT is the world's most compact universal power strip but still meeting the UK power strip's width requirement.

3.     WES.T6 and WES.eT6 will come with a built-in "Tandem connector" at the end

      Yes, you will get the "daisy-chain" feature for free.

4.     Add 4-oulet WES.T4 complete this series

      This has become a very popular model for traveling and for export companies with limited space.


   IEC-eA Series and IEC-eT Series

ON THE WAY - use IEC Connector to accept IEC C13 power cords



EuraPra® Wonpro II  –  Universal Plug Adapters

1.     TruAmp Universal Plug Adapter Meet IEC 60884-2-5


        EA Plug Adapter, White   EA Plug Adapter, Black     EAS Plug Adapter, White     EAS Plug Adapter, Black

      "True Amperage" plug adapter built using the most Innovative Direct Wiring technology

      The above shows the NextGen Wonpro II  EA plug adapter, and EAS plug adapters -- They are the SAME SIZE



      On the 25 Years Old Obsolete Design


      The picture on the left shows the internal design of the 25 old universal plug adapter. It uses 1 common socket connection module to save money, which is a very smart economical idea. However, technically this design has tons of loose parts, some are even "floating parts" (we had to tape them in place to take photo pictures). 


      Loose Connections means High Electrical Resistance, and generates enormous HEAT.  When tested as IEC 10 Amp plug adapter, its temperature rise jumped more than 120K within 5 minutes and started to MELT. For self protection, our test machine automatically shut down. We could only do 5 minute testing, not the required 1 hour testing. We won't be surprised if its temperature rise continue to jump above 200K.


      We tried a different way to see how BAD this temperature rise testing is on this old design -- to see how low we had to go to get it pass IEC 60884-2-5. The result was shocking. Its real IEC amperage rating is only 6 Amp.



      EuraPra® Wonpro II  TruAmp Universal Plug Adapters


      The picture on the right shows a completely redesigned TruAmp Universal Plug Adapter. It Rivets every connection point, make all of them extremely tight with very Low Electrical Resistance, and generates very little HEAT.  This is how we are able to pass IEC 60994-2-5 ONE HOUR testing. The only "drawback" of this design is: Every model requires its own mold. We had to build more than 20 molds. Yes, this is an extremely expensive solution, but this is the only right way to build a True Amp High Capacity plug adapter as required by IEC 60884-2-5.  Please see the IEC 60884 Temperature Rise Test Report table in the later section.


2.     Schuko Ground New "Non-Blocking" Innovative Design

      EuraPra® Wonpro II Universal Plug Adapter Products do not lose Schuko Ground and stay Universal


      There are really nothing to compare with here -- This is a brand new INNOVATION. Our "non-blocking" design has no competing alternative.


      As stated earlier, the closet design is WAS-GF with safety shutters. This design "blocks" 80% of the plugs. It can only take Schuko, Italy, Switzerland ground plugs. It can not even take US plug, don't even mention any other bigger plugs. This design is so bad -- NO new production anymore.


      WAS-GF can be used as a very good 1-to-1 plug adapter to convert Schuko plug to use with other sockets.

      For example, WAS-GF-7 is a good 1-to-1 Schuko to UK plug adapter, WAS-GF-5 is a good 1-to-1 Schuko to US plug adapter.

      EA and EAS are the only true universal plug adapters that can also support Schuko Grounding.


      Special Notes on Schuko Ground on EA and EAS plug adapters:

       EAS: Safety Shutters push the Schuko plug toward the 2 Schuko Ground metals. This helps to keep the connection very tight.

       EA: Plug Fully Inserted, Schuko connection is till very tight. But without Safety Shutters, the Schuko plug may get knocked out of position.


3.     Safety Shutters The New Perfect New Design


      The old "Slide Out" design requires so much more space. It gives WAS a very funny looking and makes it twice as big as WA.


      The EuraPra® Wonpro II New Perfect Safety Shutters "Slide In", requires no extra space. It keep the EAS size the SAME SIZE as EA plug adapter. It's a two pieces design with a locking mechanism, no need for a separate "on/off" switch. We've applied this Perfect design to all our Next Generation plug adapter products, including eR4T universal socket, EA/EAS universal plug adapters, and our 4G universal power strips.

      It is "Perfect" in the sense that we even solved the Old Safety Shutters' inability to take US "flat end" plug. US plug is so important. Any adapters that can't take US plug is not going to be widely accepted. The lack of solution leave the US market with ALL adapters without safety shutters like a third world country. To protect against serious accidental electrical shocks, we hope that US consumers will slowly discover how great EAS universal adapters are and choose them as the standard universal plug adapters. But, this transition will take some time. This is why we also offer the not so safe EA universal plug adapters to ease this transition.


4.     Highest Quality Material – Extremely Fire Resistant


      We use the Highest Quality Materials. We have new 20 years innovation Patents. We don't need to cut materials up to 30% to compete with "Generic" copycat plug adapters -- We compete with Innovation, with Creative new ideas.


      The main components of plug adapter products are Copper and Plastic

1.     Copper Quality See IEC 60884-2-5 Temperature Rise Test Report

2.     Plastic Quality  See “Burn Test” Pictures and 10 mins YouTube video

3.     We use "Supersonic Welding" technology to make our EA / EAS plug adapters as  "ONE PIECE" 

      The old design use "Snap-in Clipper" to hold all pieces together. That's the best they can do when using Cheap "ABS" plastic.

      Our Highest Quality "PC" plastic allows us to do "Supersonic Welding". You will have to use a HAMMER to break apart our Next Generation universal plug adapters!

4.     We FOLLOW STANDARDS to build our plug adapter the Right Way 

      The EA-9C and EAS-9C "EU plug adapter" follow EU Standards:  They are built with the right Angle and right Length.

      The old WA-9C and WAS-9C is a simple WA-12A and WAS-12A Italy plug adapters with the ground pin removed..

      Our EA-16 and EAS-16 are build with thicker AU plug blades, not US plug blades, not China plug blades. 

  Why IEC Temperature Rise Test and Burn Test are so Important?


The above photo pictures are found on Google images:

1.     The iPhone charger drew either 1 Amp or 2.1 Amp, but it was charged OVERNIGHT.

      This is the reason why the IEC 60884-2-5 Temperature Rise Test requires ONE HOUR of OVERLOADING TEST

2.     For Industry Usage, if anyone try to draw more than 10 Amp for Hours, imagine what a DISASTER a big FIRE can create

  IEC 60884 Temperature Rise Test Report

The EuraPra®Wonpro II TruAmp Universal Plug Adapters are the only adapters which can actually meet the IEC 60882-2-5 temperature rise test with the correctly rated "True Amperage". The following table lists the most popular plug adapter models and their test results.


IEC 60884-2-5  Temperature Rise Test Report

TruAmp Plug Adapter Rated Amp Tested Amp Tested Time Temp Rise (K)
EA-5, EA-6 (125V)        US 15.0 18.8 1 Hour 36.3
EA-18 (250V)                 US 15.0 18.8 1 Hour 36.3
EA-21 (250V)                 US 20.0 25.0 1 Hour 43.2
EA-7                              UK 13.0 16.3 1 Hour 35.5
EA-9                     SCHUKO 16.0 20.0 1 Hour 36.1

Muli-Layered 1 Common Mold CHEAP design, thus all have the same DEFECT.
WA, WAS, WASGF, and ALL "Generic" WonPro 25 Years Old Universal Plug Adapters 6.0 8.4 1 Hour 44.8


   Notes On Temperature Rise Test Report

IEC Temperature Rise Testing Rules:

1.     For adapters less than or equal to 10A will test 1.4 times (overload 40%)

2.     For adapters above 10A will test 1.25 times (overload 25%)

3.     Testing for 1 hour, the temperature rise of the terminals & contacts is not to exceed 45K

      (not exceed 45 Kelvin degree is equivalent to not exceed 45° Celsius)


The above means IEC "HEAT Generation" test is purely an Amperage issue, nothing to do with Voltage (110 volt or 220 volt makes no difference)

      The most of the world's 10 Amp adapters are to be tested at 14 Amp for one hour.

      The US 15 Amp adapters (EA-5, NEMA 5/15P and EA-18 NEMA 6/15P) are to be tested at 18.75 Amp for one hour.

      The US 20 Amp adapters (EA-21, NEMA 5/20P) is to be tested at 25 Amp for one hour.

      The UK 13 Amp adapters (EA-7) is to be tested at 16.25 Amp for one hour.

      The German/French/Schuko 16 Amp adapters (EA-9) is to be tested at 20 Amp for one hour.


Notes on Temperature Rise Test Report:

1.     We highlight 4 US plug adapters to demonstrate our technical superiority on IEC 60884-2-5 temperature rise testing:

EA-5      US NEMA 5/15P adapter (Type B)    15 Amp, 125V    tested  18.8 Amp    rise  36.3K

EA-6      US NEMA 5/15P adapter (Type A)    15 Amp, 125V    tested  18.8 Amp    rise  36.3K

EA-18    US NEMA 6/15P adapter                    15 Amp, 250V    tested  18.8 Amp    rise  36.3K

EA-21    US NEMA 6/20P adapter                    20 Amp, 250V    tested  25.0 Amp    rise  43.2K


2.     Please note that IEC 60884 Temperature Rise is only driven by Amperage.

      Voltage (110v, 125v, 220v, 230v, 250v, etc.) has nothing to do with temperature rise test


3.     In all the Adapters, US NEMA 6/20R receptacle has the highest Amperage: 20 Amp.

EA-21 is designed to be used with US NEMA 6/20R socket.


4.     Note that the most Amp you can draw out of EA-21 is 16 Amp.

Since EA-21 is an adapter, the plug which it can convert to use this NEMA 6/20R 20 Amp socket and draw the most amperage out of it is the 16 Amp Schuko plug.


5.     In other words, we only need to test EA-21 against 16 Amp rating (overload tested by 20 Amp electricity).
In order to demonstrate our new direct wiring internal interconnectivity, we went ahead and tested EA-21 against 20 Amp rating (overloaded tested by 25 Amp). This is an very high theoretical Amperage which will never be used in real world application. But, as shown in the table, we still pass this extremely high 20 Amp IEC rating requirement. After one hour of 25 Amp overloaded testing, its temperature only rose 43.2K  (please note that temperature increased by 43.2 Kevin.


6.     TrueAmp Universal Plug Adapter: The EA and EAS Amperage Ratings Meet IEC 60884-2-5 plug adapter standards.

ALL EuraPra® / “Wonpro II” adapters are Always Cool, Never Melt!

ALL WA, WAS, WASGF, WAIIvs, WAIIIvs and ALL "Generic" WonPro plug adapter are only 6.0 Amp!



EA            YouTube "Plug Adapter Burn Test"            EAS




   YouTube “Plug Adapter Burn Test” Summary

This test is to recreate the worst case scenarios heard from customers over the years where a universal plug adapter products overloaded and caught fire, including universal plug adapter, universal socket, universal power strips. The purpose of these tests are to demonstrate that the most creative innovations used to create the new EuraPra products have solved all these serious problems over the last 25 years.

We have done a separate IEC temperature rise test. But, for self-protection, the test machine automatically shut down when the overall temperature reaches 140 degree Celsius (in this test rises above 110 degree Celsius) and the old adapter started melting. To overcome this limit, we created this burn tests for 2 purposes:


1.     Finish the above overheat testing when the temperature keep rising well above 110 degree Celsius, and find its way to spread the heat to its plastic so that see how bad the plastic melting problem will be.

2.     Fire resistance test to see the dramatic difference in quality of materials used.

EuraPra® Wonpro II  Innovations: More Detailed Information

   Why Safety Shutters?

History and background:

“Safety Shutters” are designed to prevent “accidental shock by 220v electricity”, which can be deadly. This was why about 150 years ago when the world was starting to build electricity power plants, the great Mr. Thomas Edison insisted that US has to stay with 110v electricity to prevent too many human death by 220v electrical shock. 


“Safety Shutters” and “insulated power pins” are British engineers answered to Mr. Thomas Edison’s challenge. All UK sockets are required to have built-in safety shutters. All UK plugs are required to be “insulated” on the first half which can be touched by human fingers. Nowadays, more and more European countries are seeing this as an absolutely requirement to protect “child safety”. Lately we have seen a surge in demand on plug adapter with built-in safety shutters from Switzerland and other countries – even from Germany and France, which refused to adopt even the design of “insulated power pins” from the very beginning.


We have struggled with the old safety shutters used in WAS plug adapters for more than 20+ years. They are “half inside the plug adapter and half outside the plug adapter. This forces WAS plug adapter to be built in a very weird shape of and double its size. Yes, WAS safety shutters do meet the European safety standards of “no single pole can open the live socket” to prevent accidental electrical shock by 220v electricity, which can be deadly especially for young children.  This design, however, make WAS plug adapters very difficult to use with all European plugs, and literally impossible to use with any US plug.  In other words, this old design KILLED the WAS adapter market in US. Today, all plug adapters sold in US are without safety shutters, even when they are included in products exported to Europe, which is illegal in most countries. But, since nobody likes WAS, the foreign authorities always look aside because there is NO good solution for them to enforce.

25 Years Old Problem Solved

Today we finally solved the above very annoying problem and in a way “illegal” practice for a lot of products exported to Europe.

Wonpro II Safety Shutters is the world’s BEST, most compact, most EASY TO USE and standards compliant safety shutters.


Our new safety shutters is one of our 3 new biggest innovations (pending 20 years of Innovations Patents). It solves 98+% of the WAS problems:

EAS plug adapters with our new safety shutters are extremely easy to use with ALL European plugs and US “curve end” plug.

For the small market still use US “flat end” plug, simply insert the US plug at 45 degree. Problem solved.


Last but not the least, our Wonpro II new safety shutters are completely contained inside the plug adapter products (socket, adapters, power strips). There is no more half inside, half outside problem.


   Why Schuko Ground?

All our old Wonpro adapter products will lose Schuko Ground, one of the most annoying problem for our customers for the last 20+ years.  More than 80% of European people use Schuko plug. In addition, Germany is by far the biggest export country in Europe. Using our adapter products to help Germany to export their electrical devices to other countries, they will have NO critical grounding support.


Wonpro does have the WASGF series of products to support German Ground. But, the “Schuko Rim” and Safety Shutter make them non-universal. They can only take 3 grounded plugs: Schuko plug, Italian plug, Switzerland plug. It can't even take US ungrounded plug. This was a big disappointment to the US Military. They placed one order and never again.


We took an extremely CREATIVE view to solve this Schuko Ground problem. Everybody thought it was an absolutely crazy idea and it would never work. But, we did it … after very intensive R&D experiments and building 5 molds to finally get it right. The challenges of our exposed Schuko Ground metal (it has to be an exposed ground meta in order to make contact with Schuko plug) are:

1.     How to Keep Our Two Schuko Ground Metals IN POSITION?

We need to keep these two exposed Schuko metal in position at the same location and at the same height to support Schuko Ground. The first mold we built, the Schuko Ground would make contact once and then got pushed down inside the socket. We had to spend tons of R&D time and money to get this built right and actually works!

2.     How to Keep the External Schuko Plug IN POSITION?

Nothing to push the Schuko plug to maintain the contact with our Schuko Ground metal?  This was a serious challenge. It was amazing how everything work together – our new Safety Shutters will push the Schuko Plug toward our Schuko Ground metal and maintain extremely solid contact with it. With our new Safety Shutter be “in the way”, there is no space for the Schuko Plug to “escape” from where it should be.

3.     Same Location as Socket for US, Denmark, Israeli Ground Pin

The location for the Schuko Ground metal is also the ground socket for US plug, Denmark plug, and Israeli plug. When using these 3 plugs, the Schuko Ground metals will be “pushed out of the way” to allow these ground pins to enter into the socket. After these three plugs are removed, our Schuko Ground metal has to be extremely “resistant” and will bounce back to the same location where they are supposed to be.

4.     Special Note on EA and EAS Adapters

EA does not have built-in safety shutters, you are responsible to maintain the good contact between Schuko Plug and our Schuko Ground metal.  If Schuko Grounding is a serious requirement for your application you should switch to use our EA adapters. We intend to “ERASE” the bad memory from the old WAS plug adapter experience and establish the EAS plug adapter as the new standard plug adapter which supports every European requirements. This is why with those BIG INNOVATIONS, we have priced EAS adapters at an unbelievably LOW price.


News About Europlugs


April 10, 2007 


PC Magazine travel tech writer Mr. Sascha Segan first discovered our first generation Universal Power Strips. He used it in  Barcelona, Spain.  He was so amazed by how USEFUL and how easily to use to meet his international travel needs.  This is the first article he reviewed our products. We stored his article on our website. Please see the following link for details.


February 17, 2011


This is the second review Mr. Sascha Segan, he wrote a review about our second generation universal power strips – because he saw Microsoft was using our Wonpro power strip to power up their trade show booth again in  Barcelona, Spain. This is the one we ship tons and tons to Iraq to support our Military.  Please see the following link for details.




July 22, 2015,2817,2488128,00.asp


This is the third time Mr. Sascha Segan reviewed our products. We had a half an hour of long conversation. It was just happen to be before our big launch of our “Wonpro II Next Generation Revolution”, we overwhelmed him with well too much information, well too many great features and innovations. Since He hasn’t seen any of our new products yet, he decided to write in the following really “subtle” but in-depth statement:


“If you like electrical engineering, Europlugs detailed slide deck on this build process is surprisingly dramatic, and will give you some faith in its products” 

The above was before he even seen any of our GREAT new products yet.


We are helping to rebuild Iraq & Afghanistan!!!

Iraq uses UK outlets, Afghanistan uses Germany/French Schuko outlets - which means our US high-tech equipments can't get power from any of these non-US outlets in Iraq, nor in Afghanistan in effect in almost all foreign countries. Our patented Wonpro Universal Power Strips / Surge Protectors solve this critical cross-country power connectivity problem. We are very proud and very honored to have this opportunity to help our Military get connected & get power in Iraq, in Afghanistan, and in foreign countries all over the world!


US Military and Dept. of State are two of our many big customers.  In fact, during the 10 years “Iraq Operation”, US Military was our BIGGEST customer.


We took over Iraq in 2 weeks. It was a GREAT military triumph. Then, we air lift all the expensive high-tech US equipment to Iraq. Guess what?  We couldn’t power anything up.


When our military realized that Iraq used UK outlets, they bought some low quality counterfeit universal power strip and plug adapters to use in Iraq. They all overheat, melt, shorted out, caused many big fires (which burned lots of our very expensive equipment) , and killed one patriot G.I. who sacrifice everything to serve our great country.  The most dramatic case was a super hero Green Beret got “electrocuted”, not died in fighting with our enemy. This enraged his mother. She filed a very serious lawsuit against DoD. The Senate had to hold a hearing to get to the bottom of what was going on in Iraq. After that, the Military always comes to to buy my brother’s highest quality Wonpro universal products (at the time, now our Wonpro II products is 10 times better, please take a look at our Wonpro II Info page). As of today, we know there are tons and tons of Wonpro products still being used in Iraq.


Iraq uses UK outlets, Afghanistan uses Germany/French Schuko outlets - which means our US high-tech equipment can't get electricity from any of these non-US outlets in Iraq, nor in Afghanistan. In effect in almost all foreign countries. Our patented Wonpro Universal Power Strips and universal plug adapters helped to solved this very critical “Cross-Country Electricity Connection” problem. We are very PROUD and very HONORED to have this opportunity to help our Military “Get Connected, Get Power” and be all they can b in Iraq, in Afghanistan, and in foreign countries all over the world!


We were on FOX 10 TV News...

We are a small business working very hard to do our job. One day in September, 2008, Phoenix Fox 10 reporter Keith Yaskin came and gave us a surprise visit - They were doing a story about 27 US soldiers got electrocuted in Iraq, including a young special trained Green Beret, who went to Iraq to serve our country, but got electrocuted when taking a shower and died for nothing. This story was aired on 9/8/2008. We were not the center of the story. But, we were very proud that Wonpro products were used to provide the required safety for our men and women in uniform when they are sacrificing so much to do their job in Iraq.

Fox 10 posted this news report on their website in 2008. Recently, they have replaced it with other news report. Due to the special video format Fox 10 used, sorry that we were not able to download this video clip to post on our website for your viewing.

Cheap Counterfeit Adapters MELT in 6 Hours!

What is the biggest problem with those cheap Chinese counterfeit plug adapters? The PowerBright series are the best in the league and they melted in our lab after 6 hours of continuous use - Yes, they are a serious safety hazard! They melted because they are made of cheap plastic (not the fire resistant one we use)! They melted because their internal connector design is counterfeited from an obsolete model, which we have discarded long time ago (you'll have to open up the plug adapters to see the difference inside)!
