Battery and E-Liquid Indicators
Don’t waste a drop with a rechargable STLTH 5K that comes with a built-in indicator light to let you know when it’s time to plug in. There is also an e-liquid level indicator that lets you know when you’re getting close to the end. The indicators cycle through green, yellow, and red lights to show high, medium, and low levels of e-liquid or charge to help you avoid running out of either.
