From memory here is the list of kit I have had over the years:
Gamucchi (a long long time ago and it was rubbish)
TECC 901
TECC 901 Passthrough
801 Type Pipe
JOYE 510
TECC 510 with PCC
Janty Stick V1 with 801 X2
Janty Stick V2 with 801
Janty Stick V2 with 510 adapter
Janty Stick V2 with 901 adapter
SD Mk2 with 901 x 2 (dripping)
SD MK2 with Tornado Tank
Now on Lavatube Mini with Bulli
Possibly a PV with the Bulli at some point in the future if I can shake the feeling I am being robbed buying one!
I quickly realised that the bigger the battery the better!
So as you can see I have a had a tonne of stuff over the years but the current set up is by far the easiest and most consistent
