5.0 out of 5 stars 500ma per usb port, December 5, 2009

By	S. Currier (Naperville, IL) - See all my reviews (REAL NAME)

This review is from: Powerjolt Dual Universal 2 USB Blk Car Charger (Electronics)

Just got this charger from Walmart. Seems to be working pretty good. The "manual" that comes with the car charger says that it can supply 500ma per usb port at 5.2V. I was a little concerned about this with my Motorola Droid, since the wall charger that comes with the phone says it can do 850ma.

But, I put the charger through a bit of a stress test with the Droid for around 20 minutes by turning the screen brightness all the way up, turning on turn-by-turn navigation with satellite view, turning on wifi and bluetooth, and streaming high quality music over the Pandora app at full volume. The battery didn't go down at all. I started out fully charged. Not sure how it would perform over a longer trip, but for now it seems good. I am wondering if 500ma per side means 1000ma if you only have one thing plugged in.

UPDATE: I was able to charge the Droid from 60% to 100% in about 50 minutes while doing this kind of stress test scenario. One strange thing though... when I first plugged the phone in, nothing was happening. Then, I unplugged the usb from the charger and changed ports. It started actually charging. Then, I switched back and it started charging again. Then, I unplugged from the phone and replugged and nothing happened. So from that it would seem that you have to connect the phone first and then the cable to the charger. No problem for me. But then later I wanted to test it again so I unplugged from the phone and replugged. It started charging. So, I have had both results. I am pretty sure that this is something to do with the phone rather than the charger. I was using the USB cable supplied with the phone.

5.0 out of 5 stars Very compact, very powerful, doesn't get hot, August 27, 2009

We have several Palm Pre's to charge while driving and have attempted to use different car chargers. This charger stands out as perhaps the best of the lot. It is very small, provides plenty of power, and doesn't get hot. If you want a well made, small, easy to use charger that will handle charging two smart phones at the same time ... this would be a great choice.

5.0 out of 5 stars Works great for many different charging needs and inexpensive, August 8, 2009

By	Jeremy C. - See all my reviews

This review is from: Powerjolt Dual Universal 2 USB Blk Car Charger (Electronics)

I bought this charger to use in my vehicle to charge, iPhone, Samsung Magnet, Motorola S9 headphones, and Motorola Razr. It works for every one of them. The two usb ports allow me to use the data cable that came with the phones or buy ones to go with the phones. Also the ability to charge 2 devices at once is a great thing. The unit I bought from amazon is actually my second one for another vehicle (return customers to me are a great indication of a good product). This unit is very small and can easily be tucked away somewhere in the car when not in use.
