Charge:
The PB5 has six built-in batteries to form three 8.4V battery packs.
The charging circuit is completely different from that of a single battery system.
The PB5 does not support PD chargers and requires charging with a standard 5V or QC 1.5 amp or more charger.
The PB5 always uses battery power due to the six-battery structure.
If you keep PB5 connected to a charger, the charger will disconnect when the PB5 batteries are fully charged. The PB5 continues to run on battery power and when the voltage of one set of the battery pack is lower than 8 volts, the PB5 will activate the charger to continue.
