Sometimes when I see my friend got an external battery pack for his or her iPhone, I will laugh at them and say if you are serving your iphone or the iPhone serves you. Just Mobile has announced its pocket-sized new Gum battery pack for the iPhone, iPod, and other USB charging devices.
Not to be confused with the company’s original, plastic Gum, this new model features a compact design, an aluminum shell, a 2,200 mAh battery with 1A output, three LED power indicators, and an included travel pouch, micro USB to USB cable, and micro USB to Apple Dock Connector adapter. Be aware, this pocket sized external battery could only charge your iPhones and small devices. You still need a larger juicepack for your iPad.
Just Mobile’s new Gum battery pack for the iPhone and iPod is available now in silver, red, or black, and sells for 50USD. I do think it is better to bring a smaller battery pack, with more convenience and freedom.
