Battery extenders for phones are nothing new. They have been around for years. Not all of them are compact and convenient to carry around though. The Charge Ninja is different. This is a credit card sized battery charger for your iPhone. It has a 1500 mAh battery that can boost your phone’s battery by up to 85%. Since it has a USB port, you can use it to charge other smart devices.
The Charge Ninja comes with a Micro USB charging key ring, allowing you to charge your phone and other compatible devices without the need for a cable. The device is only 7mm thick around the USB port, so it is extremely pocketable. It supports “Charge First,” so your phone will charge first before the Charge Ninja is recharged. This awesome phone charger is on Kickstarter right now.
