Batteries last a long time even when chain vaping at 80 watts

Hard Hitter

Great for mechs or regulated devices. Put it in a mech and it hits hard while it's fresh. You lose the kick after a while, in some cases sooner than later depending on your build, but it's worth it. That's why I keep several in rotation.

Long lasting battery

Purchased this for my Vandyvape Jackaroo mod and it is a great battery. I'm a chain vaper so it typically lasts me around 10 hours or so.
