Black & Decker BB7B Simple Start 12-Volt Battery Booster

I bought this for my husband for Christmas a couple of years ago. His car doesn't ding at you when you leave the lights on, so he has run the battery dead many, many times. So far, every time he has needed to use this it has worked great. It takes usually about 10-15 minutes to recharge his battery before he attempts to start it. The best thing about this product is that you don't have to get out of your car to recharge your battery. This has been great as he works in an area of our city that is a little scary, especially after dark.
It is worth noting that NOT ALL CARS CAN BE RECHARGED THROUGH YOUR CIGARETTE LIGHTER. I wonder if that is why this product has gotten so many poor reviews. Before you buy this, make sure that your car/vehicle can be recharged in this manner.
And make sure you recharge it in your house after every use, or it may not work the next time.

Sorry to say I didn't like this product. I tried several times to jump start (Or charge) a car battery and it failed all the time. I have seen this in stores as "Closeouts ETC.) I think everybody is getting rid of them. I'm keeping it for a external battery supply for a GPS unit in an airplane otherwise I would have tossed it. That's about all it's good for. Save your money and buy a regular charger or trickle charger and leave it on your car overnight and it will start in the morning, but not this puppy.

I purchased this product to keep in my trunk in case my battery died. I plugged it into the wall to charge it, but all I get is an incessant beeping. The unit won't charge, and the Black and Decker support directed me to keep trying to charge it in the hopes that it might start working.

The unit won't charge. It's pretty, it looks like it could be very useful, and it has a nice design. But it won't charge.

I got this because when I am a forgetful person and have left my headlights on 3 times in the past month. I bought it, took it home, and followed the directions on charging it, and it started beeping loudly as if an alarm was going off. I know I'm not the only one with this problem ([...]), but I figured I'd exchange it to see if it was only that one that was defective. Wrong. The second one did the same thing, only the beep was different. Currently I am trying to find the time to exchange it again, and hopefully 3rd time's the charm. I'm sure it's a great product if you can find one that works, but I've had no such luck, and based on other review I've seen, neither have many other people.

Useless product. I purchased this unit and plugged it into the wall to charge it. It beeps incessantly when I pushed the recharge button, and won't hold a charge. The black and decker website says to turn it off and on, and try recharging it again, but that doesn't work.

You may be tempted to purchase this product, but you're wasting your money. Don't say you weren't warned.
