Can I use a single coil instead of dual

[stols001]

I'm glad you didn't get ripped off. Yes, you can use the coil that is in the crown (which is your tank).

The original crown uwell has a ton of coil options, so you may want to check out some of the other coils, too, not because yours won't work, but the Crown is a pretty flexible tank as far as coil options, you can also get a 1.2 ohm coil which is a very different style of vaping, and is more MTL (less vapor per puff, usually slightly higher nicotine, as you are inhaling less per puff) but you may wind up somewhere in the middle too, around 0.4 or 0.6 which is still sub0hm vaping but really tends to be less intense and cloudy than the very low ohm coils.

Best of luck,

Anna

If it is a crown Uwell tank these should work.

Come in .25, .5 or 1.2 ohm.

Replacement Coil/Atomizer for Uwell Crown

I am in agreement with @Beamslider Try changing to the .5 coil and maybe reducing watts. This should reduce your juice usage.

Well that stinks that is a lot of money for me oh well what’s done is done bit can I put a single coil in it. It burns juice fast

Welcome and glad you joined.
Looks like you did not get ripped off purchase wise. The Eleaf iStick Power 80W 5000mAh TC VW APV Mod broken in (not faulty with decent life left in the battery) along with a good tank may be a pretty good deal.
My regret is that your friend should have spent more time educating you on what you purchased and more importantly, how to use this equipment.
