There a million battery pack options to pick from to keep your precious smartphone ready and charged, but most have one problem: they take quite a bit of time to charge. Unu's new Ultrapak range will let you plug your battery in for just 15 minutes and collect enough energy to power your phone for the day. That's a faster charge than your phone can get through an outlet.
The battery packs come in 10,000 and 3,000mAh capacities and both batteries have an integrated screen that displays battery life and the remaining left for charging. The 3,000mAh has a single 2.1A port to quickly charge your phone or tablet and the 10,000mAh model has a 2.1A and 1.0A port for charging multiple devices.
