USB fast charging

With two smart USB charging ports, you can automatically detect your device and provide the most suitable charging current for the charging speed.

Method 1: Register with the crocodile wallet

This connector can give you a maximum output of 500W at 110V AC. When your car battery voltage drops below 11V, it will trigger an under voltage protection to avoid draining your car battery.

Method 2: Plug in the cigarette lighter socket

This connection method can give you a maximum of 150 watts and generate 110 volts AC. Why the power is less than 150 watts? Since the circuit limit of most car cigarette lighter fuses is less than 10A, the maximum output AC power of the inverter is about 150W when the maximum DC input voltage reaches 15V. (P = U * I) If you need more power, please connect the inverter directly to the car battery using the two terminals.

replaceable external valve

Built-in 2 * 40A replaceable fuse to protect your device from overcurrent and overcharging. 2 replacement fuses 40A are included in the scope of delivery.
