My first new 21700 pure mech mod:

Vindicator SKU 9695216 FT price 17$
Old style RDA SKU 9629096 FT price 6.15$
The 21700 Molicel P42A, cheap.

Total: 23.19$

DO NOT COPY THIS, THESE MOD CONSTRUCTIONS ARE DANGEROUS.

Just ask, and the specialists in this forum will answer.

I will write about the battery, mod and RDA results in about 10 days, just time for test.
And what to do for safe using a no chip mech mod
