eGo batteries have both a 510 and an eGo thread on them... if your's doesn't have both then it isn't an eGo battery
Mine do have both.
My ego battery fits the "PHOENiX™ Bottom Coil XL 1.5ml Cartomizer 2.4-2.6ohms" just fine.
It vapes beautifully. That proves my battery has a working 510 connection.
My ego battery also fits the "PHOENiX™ 2ml Bottom Coil eGo Tank 2.4-2.6ohm" as far as affixing it
to the outside cone threads on my ego battery.
This carto just doesn't do anything when I try
to vape with it.
When I look inside the carto's connector, it has a much smaller diameter than the 510 connector
on the "PHOENiX™ Bottom Coil XL 1.5ml Cartomizer 2.4-2.6ohms" so it's seemingly not even built
for an electrical connection to my ego battery.
My question still stands:
what kind of adapter do I need to make this work on my ego battery?
If there's something I'm missing, and these are
supposed to work with eGo batteries
without
an adapter, then two out of three of these cartos are duds. I haven't tried the 3rd one I bought.
Why should I? I'm a little leery of wasting even more juice without further advice from the vendor.
