Black & Decker BB7B Simple Start 12-Volt Battery Booster

Recieved this product from my mom for christmas. Just when i needed it I was out of town and left the map light on. I thought awsome finally after lugging this heaving thing around in the trunk i could finally use it. Didnt work. Wish i had a set of jumper cables. So mad I threw it in the dumpster at the hotel.

Even with key in the accessory position, this fully-charged device continuously "beeped" in booster-mode no matter how much I tried twisting the adapter plug into the DC outlet on a Honda Accord.

Bottom line: It was unable to recharge the car's battery.

I bought this for two reasons. First was to jump-start vehicles, second was to provide power for a fan when we go camping. It fails at both tasks. I t would not jump the 3 vehicles i have tried it on. (worthless). Two of the vehicles were SUV's the other was a e-150 cargo van. Maybe it works better on compact cars.....

Took it with us camping and hooked it up to supply power to a small fan. Worked for 15 seconds and then the fan stopped and has never worked again. It was a small 4' 120v ac van.

I am not impressed and will never try to hook any AC devices to it ever again.

I bought one of these during the winter of '06-07. It stopped working shortly after I bought it (would not charge). I called Black & Decker and they sent me a replacement. Ditto -- did not work, and failed to work exactly the same way as the first. Having only so much storage space in my house for unusable lead batteries, I did not request a third, but instead got new car batteries for both cars, and a good set of jumper cables for each -- which I never needed to use during the much more severe winter of '07-'08.

2005 Honda Pilot battery drained. Could not jump start with another vehicle. Brought the B&D battery booster at Target. Charged battery booster fully as instructed. Could not get it to work properly (tried the ignition key in all the positions). Aslo got the Duracell Instant Jumpstart System. Duracell worked like a charm.
