Product Features
Single Port Max 30W Output
The USB-C port supports a maximum single-port output of 30W. This allows it to charge devices such as notebook PCs and game consoles, which might be challenging with 20W class chargers. It can cover not only smartphones but also tablets and certain notebook PCs.
Approximately 11mm Thin with 8000mAh Capacity
Despite its 8000mAh capacity, the product achieves a thickness of approximately 11mm. It provides a practical capacity capable of charging a smartphone more than once, effectively addressing the need for “a little more power” when away from home.
Full Charge in 120 Minutes with Complete Pass-Through Charging
Recharging the battery itself supports 20W input, allowing it to reach a full charge in approximately 120 minutes when using a rapid charger. It also supports complete pass-through charging, meaning devices can be charged while the mobile battery itself is being recharged. Once the mobile battery is fully charged, it automatically switches to a direct current circuit dedicated to device charging, a design intended to suppress the deterioration of the battery cells within the product.
