It is 320 mah so that means aprox 3hrs of use before recharge. It is also bigger I think. If you are willing to go bigger I would go with the ego twist or the vision spinner in the 650 mah size. They have variable voltage which allows you to fine tune your
vape. This is the 1st I have heard of the e smart so maybe there is something great about it that I don't know about yet. If you are happy with your 808s and they still work I would research the others I recommended while still using them and then make an informed decision. Some people love their 808s and never switch. Good luck and I hope this helps. Oh.. and welcome to the forum
