Black & Decker CPI20XB 20 Watt Power To Go Cordless AC/USB Power Supply

I'd like to know that after being charged for 11-17 hours where the power went to. I recharged my iPhone but only got half way before the charging stopped and the 20 watt power supply turned itself off.

It takes too long to charge and doesn't hold the charge. I've read a lot of negative reviews about it but bought it anyways. Shouldn't.

Looking at the three versions of this: 10W, 20W, 100W, I found the technical details on the B+D site helpful:

The 10W has a 700mAh battery, This Model # CPI20XB (the 20W) has a 2Ah battery, and the 100W a 4Ah battery. It looks like they are progressively heavier, but I can't find accurate figures on weight or dimensions.

Input - 8.4 VDC, 5.0A
Output - 115V AC 60Hz-20W for 5 minutes, 16W continuous
Battery - 2Ah, NiMH
USB - 5V DC (350 mA)
- *Approximate talk time based on average results using commonly used cell phones. Results may vary depending on features/cell phone used.

November update - I ordered the product. One negative is that the power adapter provided to charge it is only for 120V countries (the US, basically)... I wasn't able to put it through any significant use so far, but I will try to test out how well it recharges electronics and how well the battery holds.

For a on-the-go, fit in your pocket power source this cant be beat. I dont know any portable power sources for this low price that give you an indicator bar (the kind you'd see on a cell phone display). This works great and Im glad I bought it.
