If you want to refill your vaping device, you should buy a device designed for that.
It definitely has an energy drink taste to it, mixed with grape.
The Geek Bar comes with a 550mAh battery, 2ml juice either 10mg or 20mg and can deliver 575 puffs.
What I noticed is that aside from the different form factor and flavors, these 3500 and 5000 disposables vape very much the same.
The sweetness is just right and I can vape this flavor all day without issue.
Please consult your physician before use.
