As anyone who owns a smartphone knows, battery use is of utmost concern, especially if you spend any length of time away from home or your office and have a hard time finding somewhere you can hook up your charger. This has become a special concern of mine lately, as this fall I’ll be spending three days camping in an area with absolutely no electricity available whatsoever. While I don’t think I’ll need to use my phone, I know for a certain fact I’m going to want to take pictures with it, and there is no way the battery, even with the extra one incorporated into my case, is going to last that long.

Just Mobile has come up with a solution that might help all of us. Gum is a pocket-sized charger that has the capacity to completely refill an iPhone. But it’s not just for iPhones; it’ll work on any mobile phone that uses a micro USB connector as well. You can recharge Gum via micro USB from any computer. It features three LED lights so you’re never left guessing how much power is left when you’re charging.

Gum measures just 7.73 x 3.64 x 2.28 cm (2.9 x 1.36 x 0.9 in), and provides 1A output. It comes with a deluxe carrying case, micro USB cable, and Apple charging cable. You can put one in your pocket today for $49.95 US (€49.95, £39.95).
