About the Yocan Flat Slim 510 Battery
The Yocan Flat Slim 510 Battery is the trimmest member of Yocan’s Flat family, a pocket-flat 510-thread battery built for daily cartridge use. Its 350mAh cell is wrapped in a slim 12 x 12 x 84mm rectangular body that lays flat against a pocket or palm and disappears next to a phone. At just 22 grams, it is one of the most discreet ways to run a standard 510 oil cartridge.
Despite its size, the Flat Slim gives you real control. A three-level variable voltage system cycles between 2.6V, 3.2V, and 3.8V so you can dial in a cooler, more flavorful draw or a warmer, thicker cloud to match your cartridge and oil. A 10-second preheat mode warms thick or cold extracts at 1.8V to keep airflow smooth, while a 15-second safety cut-off shuts the battery down if the button is held too long. It charges over a modern USB Type-C port, so it tops off fast with the same cable most of your devices already use.
The 510 threading accepts virtually any standard cartridge, and Yocan recommends carts rated above 0.8ohm for the best pairing. Simple five-click on/off operation, a bottom-loading Type-C port, and an ultra-flat profile make the Flat Slim an easy grab-and-go battery for anyone who wants dependable cartridge performance without the bulk of a larger mod.
