This has to be one of the best product that
i have bought. Only bad thing is you cant hook up everything to it or it will overload.

I didn't buy this from Amazon, but mine is just not useable. As others have noted, it is quite a bit larger than I expected. Also, it seems to charge, the lights come on normally, but it will not charge anything. It won't work on my iPhone thru the USB port, and the AC port won't power an external hard drive.

Mine may just be defective, but since I only paid $11 for it, it's just not worth pursuing a repair or replacement to me. However, just beware that it may not provide enough power to charge anything other than basic cell phones.

I bought this hoping to use it with my archos 630 video player. Sadly it doesn't even add more than 30 mins of playback time. Its made for less demanding electronics like phones, pda's etc... I wouldn't use this for portable dvd players or video players. Its rated draw power is about 350 mah.

I bought this as a battery backup for my MP3 player. I use it to listen to audio books on airline flights. It does the job fine, but I feel it is overly heavy for the job and has features, like an AC output, which I really don't need. My only real gripe is that it takes a very long time to recharge.

The product works as promised. I was hoping to get 12V DC out the charge port since that's the charge voltage. That port is blocked as an output.
