I bought 2.....figured I'd have one charging and one in my hand at any given moment....
Initially it took about 10 hours to charge using an Ego quick charger.....Since I had 2 of them I assembled them, put the initial charge on them started vaping one.
The reviews cover the rest of them.
2 with an extra charger and some 3000 mah trustfires were under 100 bucks....Cant get a VV for that!
Also, I've had verything from a 1.25 ohm carto to a 4 ohm tank (friend does the high volt vape thing) and everything in between on them and they fire on everything.Kicks an E-Power's ... for half the cash! Find something you like at 3.4 volts and vape away. I drained a 5ml tank on it between last night at work and a stop at the local watering hole afterwards and it never failed to please! (and took 3 hours to chage this morning....In theory you would never have to dis-assemle it unless you were changing the 12 dollar battery!)
