Cart battery is designed in a box mod shape or a pen shape. Plus, it is extraordinary to give more options like variable voltage for adjusting your vaping experience.

Here are some common advantages of cart batteries.

• Irregular And Delicate Shape

Want to hide your power device? Purchase it in different irregular and delicate shapes, and don't let others know what it is. The common shapes include a car key like The Kind Pen HIGHKey, a music player like Vmod, and a snail shape like Lookah Snail.

• Adjustable Chamber Size

A battery for cart with changeable chamber height and width is easy for you to load different vape cartridges. This feature makes your vapor experience more customizable. What's more, you can even collect a series of cartridges of different sizes to tailor your vaporizer by separately attaching them to such a cart battery with high flexibility like Yocan Uni Pro.

• Digital OLED Display Screen

You have already known about LED indicators above. But how about having an OLED screen to show all the status of your vaporizer? This is a screen with detailed information, including battery life, voltage level, user mode, and the present temperature, etc. Of course, it is way better than the ONLY LED indicators.
