Junopower is advertising presales of a portable device-charging USB battery called the “Jumpr” that can discharge its stored power at 300 amps, which is sufficient to jumpstart many automobile engines. They’re billing it as a pocket-sized, 7 oz alternative to the trunk-sized emergency jumpstart kits that also recharges your phones and tablets. Pre-orders are $70 and they’re promising shipments some time in May.
