Hi everyone,
I’m looking for advice on building a DIY solution to charge DJI Mavic 2 Pro batteries using a USB-C PD power bank, specifically, I have an Anker Prime 27650, which supports up to 140W output over USB-C.
I understand that charging Mavic 2 batteries this way isn’t officially supported, but I’ve seen threads suggesting it is possible with the right voltage and current setup.

I understand that charging Mavic 2 batteries this way isn’t officially supported, but I’ve seen threads suggesting it is possible with the right voltage and current setup.
What I’ve learned so far:
- Mavic 2 Pro batteries require around 17.6V at 3.5A for proper charging (~60Wh).
- Some users mention using USB-C PD trigger modules + DC-DC step-up converters to get the necessary voltage.
- Others tried using a car charger powered by a USB-C to 12V car socket adapter, with mixed success.
Use the DJI Mavic 2 car charger
- Power it via a USB-C PD to 12V cigarette lighter adapter
- This seems cleaner, but 12V might not be enough for proper charging
My questions:
- Has anyone successfully built a portable field charger using a PD bank?
- Which boost converter or PD modules did you use?
- How did you safely connect to the battery?
- Does the Mavic 2 battery BMS accept a DIY charging input? Any issues with overcurrent or thermal protection?
- Realistically, how long did it take you to charge a battery in the field?
- Are there pre-built kits or open-source projects I might have missed?
