*Warning
Use “BOOST” with extreme care. Clamps must be tightly connected to the
correct polarities of the vehicle’s battery before pressing boost button. Spark
proof and other safety protections will be disabled after pressing boost
button. This mode generates very high current. Sparks will generate when
clamps touch or are connected to each other. It may cause damage to the
product and the vehicle’s electrical system if not used properly. Seek
professional assistance if you are not sure about using this mode.
1. Connect your portable device with one end of the correct USB cable,
and insert the other end to one of the output ports (USB-A 1, USB-A 2 or
Type-C port) of the jump starter. (Note: connect the USB PD compatible
device to Type-C port for fast charging. )
