And it's working like a dream... Just something to hold us over until the VV Woodvil arrives.
It's not much stronger than a 3.7V battery with a 1.5 ohm atty, but it's consistent from first
vape to last on the battery. It's limited to 10W, which is plenty for me, but I really hated the dying battery slide. This stops that. On the flip side though, you don't get much warning when a battery is dying, so you kinda have to be aware of when you'll need a new one. I change mine pretty consistently at about the same time every day...
