these clippers are pretty good. they have a long battery life according to the display when fully charged which says 60 minutes. they come with a charging cable which can be plugged into a normal socket, or via usb, so you could potentially charge these from a computer, laptop, or any other device with a usb port. sadly they don't seem quite as powerful as my previous clippers and don't glide as smoothly over my head as my previous ones, but over all good clippers if a little pricy at full price.
please be aware, in accordance with UK law I am disclosing that I received the product at a discount in exchange for an honest review.
