Product Features
■ Single Port Max 30W Output
The USB-C port supports a maximum single-port output of 30W.
This allows for charging devices such as notebook PCs and gaming consoles, which were difficult with 20W class chargers.
It covers not only smartphones but also tablets and some notebook PCs with this single unit.
■ Approx. 11mm Slim Design with 8000mAh
Despite having an 8000mAh capacity, it achieves a thickness of approximately 11mm.
It provides practical capacity to charge a smartphone more than once,
effectively compensating for "just a little more power needed" when out and about.
■ Fully Charged in 120 Minutes, Supports Complete Pass-Through Charging
The unit supports 20W input for charging itself, allowing it to be fully charged in approximately 120 minutes when using a fast charger.
It also supports complete pass-through charging. You can charge devices while charging the unit itself. When the unit is fully charged, it automatically switches to a direct current circuit dedicated to device charging, designed to suppress the degradation of the built-in battery cells.
