Usb Charging Port - Deepace KC908 Manual

2.2.2 USB charging port

In order to reduce the burden of carrying charger, KC908 supports USB
charging, user can use ordinary mobile phone charger and "power bank" to
charge. USB charging port uses type-C connector, which supports most quick
charging protocols. The maximum charging voltage can reach 20V, and the
limit current is 3A. The charging current can be adjusted automatically
according to the voltage drop rate of the charger, so as to support most
mobile phone chargers. If the charger's output capacity is insufficient, the
charging current may be less than 500mA.
Charging time with USB charging is related to the charger. If the charger
supports quick charging protocols (PD3.0, QC3.0, UFP), it may be 2 hours. If
quick charging is not supported, it will take at least 7 hours. When charging
with power turned on, the battery power will still be consumed, just the
endurance time will be extended. When the battery is not installed, the USB
charging port cannot support the instrument to power on. We can't guarantee
the compatibility of all quick charging chargers.
No matter 12V or USB charging port is used, keep away from inflammable
and explosive materials while charging, and a person shall keep an eye on it.
When the ambient temperature is higher than 35° or the ventilation is poor,
the battery can only be charged in the power off state.
