A small hotend needs a small heater cartridge!
Just got my hands on
2mm x 10mm, 24V 35W and
2mm x 10mm, 24V 20W
cartridges. This is unbelievable small!
Wow, nice! Link?
Holy crapola. 35W and that tiny? We moving to a 1mm filament standard now or something? 
Or are you making a super tiny 3D printer?
@ThantiK I already did a super tiny printer

But you are right, it’s for a tiny printer 
What is your source for these? In the past the small ones I’ve found are very, very expensive.
