The world's most fashionable wristband power bank can provide power for your beloved digital devices anytime and anywhere. When you're playing PSP or DS games and are about to pass a level, only to find the battery running low; when you're on an exciting call with a friend; when you're out in the countryside taking photos; when you're enjoying your favorite songs on MP3 or MP4; when you're sharing songs from your iPod with friends; or when you're using your brand-new iPhone, at these moments if you use a regular power bank, it might be cumbersome and you don't know where to put it so that you can charge while continuing to use your device. It's also impossible to remove the battery to charge. In such situations, a wristband power bank is the convenient and stylish companion you need. Wearing it on your wrist not only serves as a charger but also as a fashionable accessory. Moreover, it supports various electronic products such as mobile phones, MP3, MP4, PSP, NDS, IPOD, IPHONE, etc., making it a very practical charger to have when you're out and about.
