NiteCore

NiteCore is a Chinese manufacturer of intelligent battery chargers and flashlights based in Guangzhou. In the vaporizer community, NiteCore is particularly well known for its smart chargers compatible with 18650, 21700, and other lithium-ion cells used in portable vaporizers.

Popular models include the SC4 and UMS4 (4-channel, USB-C), the D4 (LCD display, individual cell analysis), and the compact F1 as a portable powerbank charger. NiteCore chargers auto-detect cell type, adjust charging current, and stop automatically at full capacity — extending cell lifespan.
