the white ones aren't v3s, i bought them thinking they were. i use them for tobaccos.
i like the itaste v3 because it is the cheapest vv/vw you can buy in the states. they're small, they don't roll, unless you have a giant tank on them. bought them for 33-34 bucks a piece.
they have ohm meters, variable wattage (6-11w), variable voltage (3-5v) and puff counters. they are faux pass-throughs. i can use them when charging, but you are using the battery, not the ac.
not the strongest battery, but bang for buck, i love them. i get 400 to 460 puffs on the ptank 2 and davides, moe on minis and evods. so the 800mah bothers me not!
AND, if you have the battery charger, i just found a place that has them in stock for...$25.95! that is a bloody steal, that is!
Joye eGo Rechargeable Batteries
i have 4 charging cords, so maybe 1 more battery. that is the same place that has hyper tanks for $11.95. (so maybe, 1 tank and 1 battery!)
ego spinners are pretty cheap too, like 25 but dont' hit that 5 volt and aren't pass throughs, but mine is 1300mah. i have a real passthrough, just a small ego c, but it works great for the car, and for tossing in my lap, and is good for walking around with.
i think it was someone in this thread that recommended desert vapes for protanks. i had good luck with them, shipped very fast if i remember right. their coils are just too pricey.
