    Pros: the only thing that comes to my mind is on-off switch Cons: expensive for what you get - this is just ordinary 4 AA bank - no power regulation whatsoever - I would expect better product for almost $5 - I can build such box myself for less than $4 from locally sourced materials. I will have to hack this one myself to include voltage regulation ... Read more

    This product is simple to handle - put in 4 rechargeable batteries (2500 mah) hooked up to the tablet and ASUS tablet and (i was very pleased) it was charged in 2 hours completely. There is a turn off button and it's very conveniently to turn off the device It is a pity that the price is a little high than it could be and there is no light that alert ... Read more

    The best solution for this money. Packaging has been opened. The battery cover is not held, it is assumed there is no screw. On the device, there is no indicator of the charging process - just switch. Charge the phone and Samsung b2100 Sony Xperia Acro S. Charging the battery life of mobile devices comes from both the battery and on the AA-batteries.... Read more

    This piece is cheap. Maybe useful. Quality is good enough for it's price. It charges my Kodak PlaySport Camera and my Mp3 Player also works well with it. Unfortunately it doesn't charge my android smartphone Motorola XT535 via micro-usb. Maybe not enough stream for it to detect source? I don't know :( Thing worth what it cost. As I expected. Main target ... Read more

    there is an on off switch so that is good and the springs are nice, the usb connector was bent on mine but it was eaisly fixed and now is working and can be used. the cover does not snap securely closed so the lid is prone to sliding open occasionally, just keep a rubber band around it to keep it closed this is good for charging dumb devices that don'...

    Very useful in case of emergency when you don't have a nearly source of power. For example, in my case, when going outdoors to the mountain using my mobile device as a GPS and running out of battery. This tool saves me of being out of communications in an emergency. It is not the same power as a real source of power. I use it with four rechargeable ... Read more

    Good size for traveling. Cheap product to charge different electronics with connection to USB. Not charging with ordinary alkaline batteries (duracel). I used philips rechargeable batteries 2100 mAh and connect to my HTC Desire smartphone. They just charge it about 40 percent, and then began to rapidly discharge smartphone to 0 percent. I've tried other ... Read more

    I have earlier bought this unit for myself and works fine. The unit works as designed with 4 pcs AA batteries which is the best part of this product. AA batteries are readily available in every shops where battery is sold, both local and overseas. There is a on/off switch at the corner. Initially it didnt work on any devices and I had the impression ... Read more

    Cheap Useful Works as it should Build quality, the cover cannot stay in its place. Also, the plastic used is of low quality, so do not expect anything fancy. It lacks an LED so you could tell if it works or not, or to indicate low battery status You can buy this one, it charges samsung galaxy note (in difference to the 2xAA version which is garbage)...

    Flexible USB cable if enough for everything that can be connected to USB for charging. On/off swith is useful. No complicated circuitry, so it will work for long. No problems of charging or power supplying for any USB devices. Bad box cover, can fell off or break easily. Cheap plastic. Well, it works just fine, but overall build quality should be better....
