noob question: Do you HAVE to use a power supply/wall charger to recharge it?

I'm thinking about getting an meizu miniplayer M6, do you have to use a power supply/wall charger to charge it? They don't come with the mp3 player, so i was wondering if it was required and if so, what chargers do you guys use?

No it is not necessary. It charges when plugged into your computer.
Although you can charge it from an external battery pack also distributed by meizu.

every usb power that supplies power can be used, even your xbox or playstation usb port, so you do not need a wall charger / power supply.
