There are plenty of options when it comes to external batteries. If you’re a mobile device power user who needs to be able to recharge your device while on the go, away from an actual wall outlet, a good external battery is your answer. The key is finding one that is the proper balance of size vs. power based in what you need to recharge. Some batteries are specific to the iPhone. Others pack little power. The New Trent IMP99D is a beast of an external battery offering up 9900 mAh of recharging power. That’s enough to recharge 5 iPhones! It has the option to charge two USB powered devices at the same time and even works with the heavier power requirements of the iPad.
