Charging three batteries takes only 70 minutes
More efficient than the original charging butler’s round-robin mode
Triple-channel parallel fast charging, full power
Say goodbye to battery anxiety, fly all day without stress
The original charger uses a round-robin charging mode,
where one battery is charged to full capacity before the next one starts charging.
Charging time with the original 100W desktop charger:
Approximately 60 minutes to charge a single battery to full capacity.
Approximately 180 minutes to charge three batteries to full capacity.
The ISDT MA331 charger uses a parallel fast charging mode,
where three batteries are charged simultaneously without waiting.
Charging time in fast charging mode (up to 95% full capacity):
It takes approximately 50 minutes to charge a single battery to full capacity.
It takes approximately 70 minutes to charge three batteries to full capacity.
Full charging mode (up to 100% full capacity):
It takes approximately 60 minutes to charge a single battery to full capacity.
It takes approximately 90 minutes to charge three batteries to full capacity.
*This data was obtained by ISDT laboratory based on dual 100W PD input.
Dual 100W USB-C Inputs
Distinguished from the power limitations of a single-port input
Two independent and non-interfering fast-charging USB-C inputs provide higher maximum input power to the charger
You can also connect two low-power adapters for combined input, further enhancing charging speed.
Universal USB-C Input
Charge wherever you go
Charge at home
Charge in the car
Charge outdoors
USB-C Output, Charger or Power Bank
Equipped with a dedicated USB-C 45W output port, can use USB power or drone battery as the power source
