JunoPower’s Jumpr device recharges your mobile and jumpstarts your car.

Most of us are familiar with portable battery packs that recharge our mobile phones, but how about a pack that’s so poweful it can also jump start a car? Say hello to the JunoPower Jumpr — an portable battery pack that can jumpstart “almost all four and six cylinder engines.”

The Jumpr is extremely compact and lightweight, considering its power. It measures a mere 139 x 75 x 15mm — so it’s roughly the same size as many modern mobile phones — and weighs just shy of 200g (an iPhone weighs just north of 100g).

Despite its petite dimensions its 6,000mAh battery pack is capable of jumping a completely dead car battery in minutes. The Jumpr comes with a variety of cables, which can provide compatibility for a host of different devices. 

As amazing as it seems, the Jumpr is not a completely new idea. It offers similar functionality to rival portable jumpstarters such as Chromo Inc.’s PowerGo and Antigravity Batteries’ Microstart XP-3.

Jumpr is the cheapest and most stylish of the trio, retailing at $69.99 (£41.58). The PowerGo, meanwhile, offers a 13,800mAh capacity, which is enough juice for eight jump starts. Finally, the Microstart XP-3 arguably has more flexibility thanks to a handy 19V output for recharging a laptop, plus an integrated LED torch.
