Cartzpool - Premium 400mAh 510 Thread Battery with Screen | Wholesale Variable Voltage

Precise Voltage Control in a Compact 510 Battery The Cartzpool Smart 510 Thread Battery with Screen combines precise voltage control, a digital display, and a compact pocket-friendly design for 510 cartridges. With an adjustable voltage range from 1.8V to 4.2V, users can fine-tune the output in precise 0.1V increments using the simple + and – buttons. Whether you prefer lower-voltage sessions for flavor or higher output for stronger vapor production, the Smart battery gives you more control over every 510 cartridges. A built-in digital screen clearly displays the voltage setting and battery status, making adjustments quick and easy. 1.8V–4.2V Variable Voltage Unlike basic 510 batteries with only a few preset voltage levels, the 510 battery provides a wide 1.8V–4.2V variable voltage range. Adjust the voltage up or down in 0.1V steps to find the right setting for different cartridges, oils, and personal preferences. The low 1.8V starting voltage also makes this battery a strong option for users looking for lower-temperature operation with more heat-sensitive oils. Digital Screen Display The integrated screen provides clear, at-a-glance information while keeping the device compact. Combined with dedicated + and – adjustment buttons, the battery offers straightforward control without complicated menus. 10-Second Preheat Mode For thicker oils or cartridges that need a little extra help getting started, the Cartzpool 510 battery includes a 10-second preheat function at 1.2V. The low-power preheat gently warms the cartridge before use. Heavy-Duty 400mAh Capacity Long-lasting lithium-ion cell paired with an upgraded Type-C fast-charging port for rapid turnarounds and less downtime. At only 20 × 20 × 53mm, the 510 battery is designed to provide advanced functionality without the bulk of a larger box-style battery. The 400mAh rechargeable battery provides a balance between portability and battery capacity, while USB Type-C charging makes recharging convenient.
