getting my gemini soon

Hey guys i ordered my gemini and i have a question of first time use, should i do anything different than just pop on the cartridge and start it up? I orded 1 thing of eliquid and 5 extra blank carts, ive read on some things, that I should put a drop or 2 of the liquid on the atomizer and then fill the cart for the first time use? is that important or can i just use one of the pre filled ones that comes with it and just start it up? is it necessary to charge the batteries to full before first use?

just want to do everything correctly so i get the best experience out of this, thanks guys!

My Gemini PCC and batteries came partially charged. I did charge the PCC it only took about 20 min for the amber light to go off.
As for the batteries. If they have a charge. Go for it. I did. with the regular atty I just pushed a filled cart into it and let it set for a couple of sec's. I was able to get good hits with about 2 or three drags.

The batteries will take about 1.5 hours to charge in the PCC.
The PCC fully drained will take close to 5 hours to charge.

Let me know how your heavy hitter works. I still haven't been able to get mine to work without having a metallic taste after one drag.

ok cool, Im probly going to try the reg atty first with the pre filled cart once i do that for a bit ill try doing the eliquid in one of the empty carts with the heavy hitter and c if its metalicy like urs is...haha we shall c
