Slash your surface interval. This dedicated fast-charging kit — power cable, smart-voltage adapter, and precision cradle — replenishes a 158 Wh SUBLUE battery in about two hours, getting you back underwater up to twice as quickly as the standard charger. Purpose-built for power: Calibrated exclusively for SUBLUE’s high-capacity 158 Wh pack to deliver a steady, optimized current without stressing the cells. Plug-and-dive simplicity: Snap the pack into the cradle, connect, and the intelligent circuit takes care of the rest — balancing, monitoring, and safely topping off every cell. Versatile compatibility: Perfect partner for Navbow, Navbow+, Tini, and Swii scooters. Safety first: Integrated temperature and over-voltage protection meet international certifications for worry-free charging. Important: This charger must not be used with the 98 Wh battery!
