The Yocan Flat Mini is a compact cart battery built around a 400mAh rechargeable cell and a universal 510 thread, so it works with most standard oil cartridges. Its flat, square body sits flush on a table instead of rolling away between uses.

• 400mAh rechargeable battery
• Universal 510-thread connection
• Three adjustable voltage settings
• USB-C charging
• Automatic shut-off after periods of inactivity

A no-fuss, pocket-sized 510 battery for everyday cartridge use.
