Not the Juno Power Jumpr. This blue brick may look like a lot of other chargers out there, but it’s powerful enough to juice up your phone, tablet…or car.
Yes, in a pinch you can use the Jumpr to jump-start your auto. The 6000 mAh, cell-phone-sized charger is capable of delivering a 12-volt, 300-amp output from a dedicated port. It comes with a jumper-cable attachment, and the cable has a built-in chip designed to prevent reverse charging of the Jumpr’s lithium-polymer cell. According to Juno Power, the Jumpr should work with four- and six-cylinder engines, but its 300-amp output may not be enough to turn over a V8.
