Recharging This Backup Battery Takes As Little As 15 Minutes

A backup battery can be a lifesaver if your phone is on the brink of dying—but only if it isn't dead as well. External power packs can usually take hours to charge depending on their capacity, but UNU claims its new Ultrapak GO and TOUR batteries can be charged enough to top off a smartphone in just fifteen minutes.

The $60 Ultrapak Go boasts a 3,000 mAh battery inside, and while it requires a full half-hour to completely recharge, it can be topped off to 2,000 mAh in just fifteen minutes. The same goes for the $100 Ultrapak Tour. Its 10,000 mAh battery requires just over an hour-and-a-half to fully charge, but it can be ready to save a smartphone with 2,000 mAh power in just a quarter hour.


Both batteries will be available starting June 30, but can be pre-ordered now. And in addition to lightning fast charge times—presumably at the cost of a shortened lifespan—they each feature a simple display indicating their current charge level, and an estimated countdown to when they'll be topped off when charging. That feature alone is worth the price of admission, since deciphering blinking colored LEDs is rarely an exact science. [-My UNU]
