Black and Decker Portable car battery Chargers

Portable Car Battery Chargers

The Black & Decker JUS500IB shines as a car battery charger. It can jump-start your battery in most conditions and has several other features to help in a roadside emergency. Though it doesn't function as a trickle charger, this is still one of the best car battery chargers and our Top Ten Reviews Silver Award winner.

Charging Capability

Even in cold temperatures, when it's more difficult to jump-start a vehicle, the Black & Decker JUS500IB won't struggle much. Its cold cranking amps (CCA) rating of 500 ensures that. With 1, 000 peak amps, this car battery charger has enough juice to turn most engines over, which is the main point of having a tool like this. However, you can't use the JUS500IB as a trickle charger to maintain or top off batteries.

Portability

When you're trying to jump-start your car, you don't want to be hindered by cable length. The JUS500IB comes with jumper cables that are 2.5 feet long. While that's a little shorter than the best car battery charger's cables, it's enough length to give you some freedom of movement.

For the sake of portability and convenience, Black & Decker built storage space for jumper cables into the JUS500IB. This means that you don't have to have a separate set of cables lying around and taking up space. It also means that the JUS500IB's cables can be nicely tucked away and aren't a hassle when you move the charger around.

Some battery chargers can be pretty heavy, so it's nice that the JUS500IB has a handle. That makes its 16.5-pound bulk significantly easier to move around. While not the heaviest portable car battery charger on our lineup, it's certainly not light.

Safety

When the JUS500IB needs to be charged, all you have to do is plug it into a wall outlet in your home. Because it has overcharge protection, you don't need to worry about leaving it plugged in for too long. Older car battery chargers, and some new ones, don't have overcharge protection. With those, you need to be careful, because they don't stop pulling electricity from the outlet when they're fully charged. This can lead to exploding batteries – all of that energy needs to go somewhere.
