Humble Root Digital 510 Battery

This 400mAh vape battery keeps things easy but powerful. Five clicks turns it on or off, two clicks starts pre-heat, and three clicks lets you switch between low (3.4v) and high (4.0v) temps so you’re always in control of your hit. There’s a built-in screen that shows your temp setting and battery life (no more guessing), and it charges up fast with USB-C. Just plug in, power up, and you're good to go. Clean design, smooth pulls, and no extra fluff. Just a reliable battery that does exactly what you need—really well.
