Juno Power's new Jumpr is small enough to fit in a glove compartment, and light enough to carry in a coat pocket or backpack, but is claimed capable of jump-starting a car. And it can charge your smartphone, too.
The Jumpr measures 5.5 x 3 x 0.6 in (14 x 7.6 x 1.5 cm) and weighs 7 oz (0.2 kg). That's not hugely dissimilar to a Samsung Galaxy S5, albeit a bit thicker and heavier. It is certainly a dramatic departure from traditional briefcase-like jump starters and Juno Power says it's the smallest you'll find.

The device houses a 6,000 mAh lithium polymer battery and produces a 12 V output at a peak of 300 Amps. Juno Power says, "300 Amps is enough to jump-start almost all 4-Cylinder and 6-Cylinder engines as well as possibly enough to jump start more depending on type of model."
In addition to jump-starting a car, the device features a 5 V/2.1 Amp USB output that can be used for charging mobile devices such as smartphones and tablets. With its 6,000 mAh battery, the Jumpr should charge a Galaxy S5 (which has a 2,800 mAh battery) more than twice before needing a top-up itself. A flashlight is also featured.
The Jumpr is available now for US$89.99.
