The DJI Power 140W GaN Charger is currently available for $59.49 on Amazon, marking a 15% reduction from its standard $69.99 list price.
Technical Specifications and Charging Capabilities
The charger utilizes Gallium Nitride (GaN) technology to manage power delivery, providing up to 140W of output when operating in ambient temperatures between 0° and 25° C (32° to 77° F), as specified by the DJI USA official store. The device includes a built-in over-temperature protection system that automatically throttles power output if the unit reaches a safety threshold during full-load operation.
Users can utilize three ports simultaneously, with the charger employing dynamic power allocation to prioritize connected DJI devices. According to DJI, this priority function requires a DJI Power 7A USB-C Digital Display Cable plugged into either the USB-C1 or USB-C2 port. The unit supports multiple charging protocols, including PD 3.1 for its two USB-C ports, and UFCS, QC 2.0/3.0, SCP, FCP, AFC, and Apple 2.4A for the single USB-A port.
Did you know? The DJI logo on the charger housing functions as an LED status indicator, providing visual confirmation when the device is actively drawing power.
Performance Metrics for DJI Drone Batteries
DJI reports that the charger can replenish three DJI Air 3S batteries in under 180 minutes or three DJI Mavic 4 batteries in 240 minutes. These figures were measured in a 25° C (77° F) lab environment; the manufacturer notes that actual charging times may fluctuate based on ambient temperature, remaining battery level, and the specific drone model.
When using a drone charging hub that supports 100W output, the system can achieve 100W fast charging via the USB-C port. DJI advises that users should unplug idle cables when not in use to ensure the charger does not limit the maximum power output available to other connected devices.
FAQ
Does the charger work with non-DJI devices?
Yes, the charger supports various protocols including PD 3.1, QC 2.0/3.0, and others, making it compatible with a range of consumer electronics. However, the priority power allocation feature is specifically optimized for select DJI products.
What happens if the charger gets too hot?
According to DJI, the charger features a built-in protection system that automatically reduces power output if the temperature reaches a safety limit during 140W operations.
Can I charge three devices at once?
Yes, the unit features three ports. If a new device is plugged in, the dynamic power allocation technology allows existing devices to remain connected, though a brief disconnection may occur as the charger re-initiates a protocol handshake.
