USB-C direct charge batteries have built-in charging port, can be charged directly with USB-C cable, no need to buy additional charger. High charging convenience, business travel only needs one charging cable to charge batteries.
USB-C direct charge batteries integrate charging management circuit internally, with overcharge protection, over-discharge protection, short circuit protection and other safety functions. Charging process automatically managed, stops when fully charged.
Dedicated chargers charge faster, typically 1-2 hours to fully charge 4 batteries. USB-C direct charge batteries single cell charging time about 2-3 hours.
Dedicated chargers can charge multiple batteries simultaneously (typically 4-8 cells), suitable for high battery usage scenarios. USB-C direct charge can only charge one cell at a time.
Dedicated charger version batteries are slightly smaller in volume (no need for built-in charging port), suitable for devices sensitive to battery dimensions.
Household users, business travelers: Recommend USB-C direct charge version, convenient charging, no need to carry dedicated charger.
Enterprise users, high battery usage scenarios: Recommend dedicated charger version, high charging efficiency, can charge multiple batteries simultaneously.
