I used this device to power a wireless network webcam. Now I can take the webcam anywhere in my building and be able to broadcast video to anyone logged onto the webcam's web-gui.

I received my new unit, 100W capacity, and after charging it for 3-days, it could not hold a charge. I followed the instructions to contact the company before trying to return it and foul]nd out that Black & Decker customer support identified it was the batteries with in the unit. They had no spare batteries classifies this product as obsolete and therefore will not pursue supporting it. I am returning it for a refund. WHAT A WASTE of MY TIME!

I purchased the Black and Decker CPI100B to power my Pioneer Inno portable XM radio and portable Saitek speaker. When connecting both units to a fully charged CPI100B, the unit would cut out after 5 minutes. I then tried to power the portable speaker by itself with a 12W maximum output on the CPI100B and then unit would cut out after 20 minutes. The portable speaker typically lasts 2+ hours on 4AAA batteries so I was hoping for at least double the performance. The only use of this product would be to charge a cell phone or other very small electronic device. I doubt it could even power I cannot recommend this product and would advice people to not purchase it and perform research on a similar product.

With the advertized 4AH battery, I was hoping to power some of my low-mid power (15W to 40W) lights and tools. The B&D worked fine for the first few recharges (I was able to get 1-2 hours runtime) but then dropped to 20-30 minutes. I have the same problem with their 20W power supply. I am giving up on NiMH-based batteries and planning to try the Xantrex/Duracell with the Li-ion batteries.

I bought it because my kids use a lot a portable DVD on flights and its battery are not long enough anymore. I bought this black and decker to have a little more DVD life while in the airplane. And it helped just perfect!!! The only thing is that it is a little bit bigger than I thought it would be, but anyway, it is ok!!!
