Modern mobile phones need a lot of power; chances are we’ve all got an external battery pack (or at least a second cable and wall plug) tucked away in a bag somewhere that will charge up our Android and iOS mobile phones while we’re on the run.

The thing is, those things need to be taken along with you when you leave the house. If you’re like me, though, that requires a heck of a lot of cognitive overhead and pre-planning.

The whole point of the Nipper, this tiny new mobile phone charger that uses two AA batteries to give you a bit of juice when needed, is to always be available.

Do away with the hassle of countless charging cords; with the Speedy desktop USB charger, you can simultaneously juice up five devices with just one unit — and for a limited time only, you can get yours for just $21.99 — 26% off — through Cult of Android Deals.

This rock-surface battery pack is just what you need to stay charged no matter what the day brings.

The SHARKK packs tons of power and includes optimized outputs for charging both tablets and phones, and thanks to Cult of Android deals, it’s half price for a limited time.

Researchers in the U.K. have developed a cellphone that is charged by ambient sound, eliminating the need for a charger. Filled with energy-harvesting “nanogenerators,” the device uses a principal called the piezoelectric effect to turn the sound vibrations in the atmosphere around it into energy.

Motorola has been keeping the Moto 360’s charging method a secret since its first unveiling earlier this year, but new photos of the device reveal its unique wireless charging dock for the first time. Unlike the LG G Watch and the Samsung Gear Live, the Moto 360 doesn’t appear to have any external connectors on its back, and it’s a great bedside clock while it’s charging.
