I waited for the eGrip to go through a few charge cycles before averaging the time it takes to recharge from the wall-wart. From a totally drained battery to full, it's been taking on average, two hours..
As far as vaping time goes... Out of two days... 6 hours one day, 8 hours the next, @ 11-14 watts. The time is based on my using the device while leaving the house, and conducting daily tasks. I vaped as I normally would with any other regulated device. It is perfect for my intended purpose..I'm going to grab an automotive 12v outlet >USB adapter to charge while in my car, using the eGrip as a pass through while driving.
It's been great to have something work as described out of the box.. So small, simple, and well made. No leaks, gurgles, or surprises so far.![]()
Thanks for the update. Do you find this device to be limiting as far as changing out liquids/ flavors? Or --maybe you don't change liquids frequently and that's a non issue for you but was curious.

They are good, but for the price, could / should be better IMO. Still a fine little device nonetheless..
