Pipo W3F keeps rebooting, can anyone help?

Sorry if this is in the wrong forum but I didn't find a Pipo subforum.
My Pipo W3F keeps rebooting exactly like this fellow's https://www.youtube.com/watch?v=Dz_qsKDAq3A

Can anyone help? Thank You.

Pipo W6s charging problem

I have taken delivery of a Pipo W6s. It is a android/windows dual boot with stock rom as delivered.
There is a problem when attempting to charge. It runs while plugged in, but will not hold a charge. When plugged in it states 'plugged in, not charging'. i have tried several different chargers including the one it came with, and have the same problem with all.

Is this a hardware issue, or something that can easily be fixed?

I'd be grateful of any help, as I can't even seen to get it in to recovery (im a bit of a newb still!)
