Needing your phone to make an important call when it is running low on battery is not fun. There are plenty of battery extenders you can pick up to recharge your phone on the go. Not too many of them are as fun or stylish as the QBracelet. This is a wearable device with a 1,160 mAh battery that adds up to 60% extra charge to your iPhone 5s. Its built-in Micro USB or Lightning connector (your choice) allows you to charge iOS, Android, and Windows phones.
The QBracelet has a lightweight design and looks like a piece of jewelry. It is available in 3 sizes and 5 colors. The device is expected to retail for $99, but you can get it for $79 for a limited time.[where to get yours]
