Sadly the Kospet Prime mk1 seems to be end of life - for various reasons.
However, our friends at Kospet are releasing a replacement for this particular model - The Power.
It has very similar specifications as you can see below.
It is on sale now at a very reasonable price - however - they have made an error and say “wireless charging” on Gearbest.
It does not support wireless charging - they are meaning to refer to the power bank 
Currently on sale at Gearbest
