A 5-minute charge for this portable battery can fully recharge an iPhone 5

Portable batteries for charging mobile devices are great. Until they run out of a charge too. Then it’s usually hours of plugged-in time to fill the power pack back up. Not so with the Pronto: A portable battery charger that can ingest enough juice in just five minutes to completely recharge a dead iPhone 5.

Pronto is a Kickstarter project, which comes with the usual caveats: You’re backing an effort, not an actual device so consider wisely before funding it. But the idea of a fast-charging portable battery has already taken off because the project met its funding goal in only five hours. With 29 days to go, the Pronto project has raised $93,707, which nearly double its $50,000 goal.

So how does it work? The Pronto — available in two sizes and capacities — can handle a full 25 Watts while plugged in, so it charges very quickly. Both models can be fully recharged in one hour.

That means in 60 minutes, you can carry an additional 4,500 or 13,500 mAh of power for your phone or tablets. The USB output of the Pronto can supply a 2.4 Amp current so it can even charge the new iPhone 6 or 6 Plus faster than the standard Apple phone charger.

The smaller capacity Pronto 5 will retail for $99 but early birds can back one for as little as $69. The larger Pronto 12, which includes a pair of USB ports and a 12V jack for charging larger devices, is expected to cost $149 on the market; a $30 discount is available to early backers.
