I wasn't sure what the joy 302 was, googled it and found:
Model Number: JOYE 302
Manufacturer: Shenzen Joye Technology, Co., LTD.
Similar Models: DSE801, RN4072
Parts Interchange With Other Models:
Length: 108mm
Atomizer Type: cylinder
Battery Power: 180mAh
Alternate Names: Classic Penstyle
I'm using a Joye eGo standard 650ma battery for all my
vaping. Adapters are
the most important part of ordering after attys and
juice.
I use a 510 to 801 adapter, works great, even debridged a 801 atty (didn't work at the time)
that now is great for dripping! (My newest passion

)
I also have a 801 to 510 adapter, so my 510 attys work on my 801 pass thru, when I
get up the energy to mess with a PT, (eGo battery is more convenient)
Try all possible combinations you can, my eGo battery, adapted to 801, adapted to
510, with debridged 510 atty, dripping works great. I was curious if it was possible.
