iClever’s USB battery pack/car jump starter is more powerful than most at 600A, enough to get the engine turning over in almost any car. And as an added bonus, it supports Quick Charge 2.0 input and output, allowing you to recharge your phone faster, and then refill the battery pack in half the time it would usually take.
These jump starters are the kinds of things that you never feel an urgent need to purchase, but that you’re really glad you bought when the time comes to use them.
