Be careful what power adapter you use
Only used it once so far, and seems to work, but note you can't use an iPhone USB charger with it (the small square power brick that comes with all iPhones), you need to use a 10W ipad charger or buy a $10 5V/2A charger. If it requires a certain amperage, it should come with the adapter. From the product description:
Note:
• Remove any metal phone cases or any cases thicker than 5mm before use.
• Using an Apple 5V / 1A charger is not recommended. Overheating may occur.
Input: 5V / 2A
Output: 5V / 1A
