I got two samples of this product, one black, one white, a few months ago and finally got around to testing them. USB chargers are a difficult product category because the USB spec was never designed for the current/amps (and thus wattage) that today's products require. In a desire to not damage computers, most high current/amp devices have special chargers that have the signal wires configured in a special way. That way, when the device connects to their charger, they'll know they can draw all the current they want. When they don't see the signal cables properly configured, they only draw what the USB spec allows, thus preventing them from damaging that charger (or computer).

It's a fine solution to a tough problem, but unfortunately some of these signal wire configurations are directly contradictory to each other, (specifically Apple vs everyone else) leaving 3rd party chargers in a bind. They can't support all devices easily, even though they all use the same plug. The result is that lots of chargers don't charge lots of devices at full potential.

To learn more about the particulars of this, see my previous review of the 10 watt PowerGen charger here:

The PowerGen line has solved this problem by having each of their ports configured differently. This was true on the older 10 watt and remains true for this newer edition. The result is if you use the correct port, this device will work with more devices than any charger I know of. If you've got just about any Apple device you're covered. It'll cover almost all Android phones and many of the tablets, but some of the special tablets, it won't.

We own a ton of electronic devices and since they are all portable they go with us in our vehicles. Toss in a couple of grandkids and add in their equipment and then you have a lot of electronic devices being used on long trips that need to be charged. You might also be limited to the number of car power sockets that are available in your vehicle. Most USB car chargers have one port and they are limited to 1 Amp or 2 Amps output. This big brother of all chargers has two USB ports and can handle 15 watts of DC power or 3.1 Amps of total charging power. That means I can charge my iPad 3 and my iPhone simultaneously without any issues and at full speed.

This is a good car charger that features two USB charging ports that can be used at the same time. One USB port is designed for Apple products and it is labeled with an A. The NA port can charge your iPhone and any other compatible USB device. My iPad 2 and my iPad 3 could only charge in the A port. Both outputs are rated at 3.1 Amps but the total current out of both ports combined while in use at the same time is 3.1 Amps

The unit comes with no cables but since it is touted as a universal charger and there are so many different types of charger cables I cannot fault them for not supplying one. Many chargers with cables are over $20 to $25 and the cables may only fit one family of devices.

* Dual port
* Charge an iPhone in either port
* Can charge the iPad 2 or 3 in the Apple A port at 2 amps even if you are charging your iPhone at the same time
* Both ports charge up to 3.1 Amps if only one port is being used
* Nice red LED light around USB ports so you can see it in the dark, know it is in a live car charging port and you can see the USB plug location.

I tested PowerGen Dual Port USB Car Charger with Nexus 7 Tablet, Samsung Galaxy 7.7 Tablet, and Samsung Galaxy Nexus cell phone, and SanDisk Sansa Clip+ player. My original test for Nexus devices was using Jelly Bean 4.1, I repeated the tests for Jelly Bean 4.21 and saw a significant difference. I updated this review to show the differences between two releases.
I received PowerGen car charger for testing from the manufacturer to write an honest and unbiased review and you will find both pluses and minuses of my experience in this review.

I am attaching a collage of 3 photos labeled with numbers 1 through 3 under customer photos that I will be referencing in this review.

The first thing I noticed that this car charger is fairly short (3 inches in length, 1 inch by 1 2/8 in width). Photos #1 shows this plug plugged in.

The plug has two ports labeled "A" and "NA" which stands for Apple and Non-Apple devices. I own all Android devices but I tested both ports to see their behavior with my devices. The charger comes without a USB cord, so tested it with the USB cords that came with my devices.

I used Battery App to determine how each device recognized the external battery pack. 'AC' status means the charging is at full charging rate. 'USB' status indicates charging at a lower charging rate. 'Discharging' status means that the charging rate is below the power that the device is consuming so it slows down the discharge rate but does not re-charge.

The key findings:
(1) Samsung Galaxy 7.7 cannot be charged with this car charger with either port
(2) "A" port provides reduced power for some non-Apple devices and does not work for others
*** Update 1/11/2013 ***
I repeated the test with Nexus 7 running Jelly Bean 4.
