    I've bought a few of these type things and most of the time they don't work at all. These work pretty well, at least for maintaining battery and moderate recharging. So, considering the flexibility of using AA if you, like me, already have recharcheable batteries as the foundation of your electronics system make them a really good choice. The additional LED light is nice to have, but I fear the ergonomics of the switch will create inadvertent battery depletion if the light gets clicked on. Also, in a hurry, and everyone who is really in a hurry will understand, if you push the switch the wrong way it may not charge your device. I prefer no-brainer ergonomics in these type devices. Also, the battery cover is kind of annoying. I wish there was a version that retained the batteries well enough that the cover was not needed or at least was easily used or not for aesthetic reasons only.

    I was amazed at how inexpensive this emergency charger was. It arrived and it looked somewhat cheaply made. I inserted two AA batteries and got the charger cord for my iphone (no cords are included) and it started charging. It seems to work. I don't know how long it would take to charge a phone since mine was nearly fully charged when I test this Docooler. I wanted a charger that uses batteries in case of a power outage. I plan to keep this charger on hand for an emergency. I figured it would work to charge the phone for a few calls. The cost is low and this is a lightweight plastic charger. Don't expect high quality but it seems to work.

    The "emergency charger" actually does what it says. The unit has a built in white LED light activated by a switch on the side. The switch allows the user to select between "light, off, and USB." It's slightly larger than the two AA batteries it contains. The battery compartment is accessed by holding the top (by USB port) with a thumb & forefinger of one hand and gripping the bottom of the unit with the other hand and pulling down. There is a diagram inside that illustrates how to insert the batteries. I tried it on the iPhone 4S and it seems to charge the phone without issues. When the switch is in USB mode there is a red LED indicator light that activates on the top side of the charger. Other then the slower then usual shipping no problems.

    I am still searching for the perfect solution. This is not perfect but the best I have found so far. They will convert AA batteries into an iPhone charge. I use my Iphone5 as a GPS, camera, notes, iBook, music etc while camping and as an email machine while traveling. I need a lightweight charger that runs on 2 (not 4) AA batteries. This thing works great. What I don't like is that the batteries get hot, which is not a problem winter camping (hand warmer) but a valid concern on a plane. I have never had smoke but they do get hot. I tried the modification of clipping one of the middle pins on one but it wouldn't charge after that; I may sacrifice/test another one. I have also bought one or two defective ones so I buy/carry extras. They are cheap, lightweight, compact and disposable. I would pay more money for one that doesn't get hot but I can't find a 2AA with decent reviews. These things work well for charging an iPhone. The flashlight is better than nothing but not by much. They are not perfect but certainly worth the price.

    This was intended to be a backup for my iphone 5C while backpacking. It works. I kept the one of the batteries in backwards until I needed it. It charged the phone a little bit, enough to get some messages and calls out at the end of the hike. It's light weight and size made it ideal for this application. Now I keep it in my daily carry bag, just in case, but I have only needed it once and was glad I had it.

    works as described by many. not very powerful, gets hot. however it's key in my earthquake kit. the power chargers that you have to pre-charge with electricity won't be much use when the electricity is out, but this should keep me going for quite a while, since i stockpile batteries for emergencies.

    Used it to keep a charge on my cell phone while on a bus trip. Worked better than I expected but it got really hot after charging for a while..

    power leaks when it is off and one of the batteries slots are too loose but other than that im surprised as to how useful these have been. i bought 4 and all of them work great but the all have the same problems described.

    It can be handy but keep an eye on the switch. it is best to leave the batteries out until use.

    Works well but it does get hot. Great value and you can keep one with cable in the car as well as at work or anywhere else.
