Charging battery


#1

Hi, my son had a kit bought for him for xmas. When we finished building nothing happened so I presume the battery needs charging.

The video on charging shows the micro usb connected to the battery but my battery only has 2 USB ports. Do I need to now buy an adapter for the micro usb to the mains? We are in the Uk

Thanks
Nick

There should be a charging port on the side of battery
