I had emailed back in june one vendor to carry the e-power 14650. The response back was it had too many problems.
Now this was not true. the e-power 18650 is the one with problems.
I have both ordered from here:
E-Power From Smok Tech and HECS
They are an ecf registered supplier.
I have been using e-powers for last 6 months and myself have not have any fail on me.. touch wood.
I have had no custom problems, never order
juice with hardware.
May be someone else has a discovery I have not found yet.?
