Works better than advertised used it to charge my cell phone today and took only thirty minutes through a lightly tinted Window but still in direct sunlight.

I used it recently to charge my phone while I was not near an outlet for doing so. Worked great and worked quickly. I'm very happy with it. Looking forward to seeing how it does at charging a phone and a tablet at the same time. This charger will be getting a workout!

I have used it a couple of times so far to charge my phone while still in my pocket. Works as expected. Very happy with my purchase.

I like the fact that it can even charge my cell phone.  I wish it could play usb when inserted.

Works great to power my phone, use car gps away from car.  Great to charge phone on the run.  Am going to experiment with wiring a usb cord with two of them in series with one positive and one negative connected from each battery to see if it works like a regular battery and I can achieve 5.5+5.5=11 volts.  Will try to come back to update when I get time.  Then I can use it to power things like 12 v lights and other devices.  Highly portable.  Flashlight came in handy too when needing to see under car.

This device works great as advertised!  Doesn't take much longer than my iPhone to fully charge and then can be used to fast charge my iPhone 2-3 times!  Great way to always have excess power when I'm out responding to ministry needs and away from power source for extended periods.

And now I will by one for me. This was for my son Christmas gift to charge his new Samsung S4 and it worked great...be careful with the cover you choose for the cellphone, if its to bulky it will not allow the phone to charge....

works as advertised. charges slightly slower than plug in. my usb port was broken so it make a broken phone usable. not 5 stars due to charging speed but thats not really the products fault,

I was skeptical for a long time bcoz of its price.  I have seen few at $2-4 on ebay and Amazon.  After having a bad experience with a couple and the good reviews to this product I thought of giving it a try and my oh my.
I own a Samsung Galaxy note 2 which has a humongous 3200 mAh battery but this thing charges 15% in about 20 mins while using GPS. That is faster than my charger at home.

This has worked in my unheated garage for several months. It charges my phone quickly using the usb slots.  I thought the orice was decent too.

I was so excited to get this product and just charge it and have it in my car for emergencies.  I was pleasantly surprised it came 93% charged.  Charged up to 100%.  Seems to be holding a charge for a few months now.  And it even works.  We just used the air compressor.  Also, it has charging ports for cell phones in case of emergencies.

I've bought a couple of mobile chargers while traveling and none have been compatible with my devices for whatever reason. I bought this not because it was the cheapest but because I needed one and didn't want to risk another dud. Anyway, not only does it work on all my android devices BUT it works as advertised. Got my wife's tablet from 0-50% using only a quarter of it's juice and in less than an hour. Good stuff.

This charger has a much higher amperage on the 5V output (950 mA) than my other chargers.  It charges my Droid RAZR, the wife's Blackberry Bold 9930, and even her Kindle Fire!  I liked it so much that I ordered another one for my wife's car too to replace her weaker charger.

Bought this inverter w/ usb outlet for charging up my phone in my car. Using the inverter charges my phone faster, especially if I'm using the GPS option and mp3 player. I also bought the inverter for using pwr equipment, which has worked w/ electric blower.
