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
Provides rapid charging for remote controllers, smartphones, and other devices
Meets the emergency fast-charging needs of most mobile devices and remote controllers
*When paired with a battery, it functions as a 16000mAh power bank, ready to handle unexpected situations, eliminating battery anxiety.
One-Click Storage Mode Activation
Charges the battery to 60% of full capacity
Convenient for long trips, air shipping, or extended storage
Maintains battery health
One-Click Fast Charging Activation
Rapidly charges the battery to 95% of full capacity
Saves approximately twenty minutes of charging time
Ready for immediate flight without delay
Innovative Battery Balancing Feature
Collecting Mode:
Allows you to transfer energy from multiple batteries
into the one with the highest remaining capacity
Helps meet additional flight missions in emergency situations
Balancing Mode:
Equalizes the charge levels of multiple batteries
that have different capacities
Convenient for transportation or maintaining battery durability while on the go
Quiet Turbulent Flow Fan, Fast Charging Without Overheating
Maintains cooling without slowing down, efficient and cool fast charging
Optimal heat dissipation, suitable for high-load work throughout the day
Fast charging even during scorching hot summers
Battery exposed design,conducive to battery heat dissipation, fast charging without heat
