There’s a 19mm joyetech ego one, I was going to get one a while ago for my k3 mini but ended up not bothering with it.
I’m sure there was a 19mm 2200mah one. Could be wrong. Think the adjustment is a bit limited, but it might be decent depending on what you’re using it for. The one I was looking at was 100mah but appealed because it was really short.
Thanks but I'm not looking to spend £250. Lol.Dicodes Tiny?
