Can DJI Mini batteries be charged from a 12v supply?

Questions & Answers

Hi Guys, I’m new to this pastime and have not acquired drone yet. After doing research and reading post on this excellent site. I’ve decided on a DJI mini or mini2. I spend up to 6 months a year in my motorhome, mainly without electric hook up. Can anyone inform me as to whether these drones batteries can be charged from a 12 volt supply. Cheers.

With a third party / aftermarket charger, yes.

With an official DJI Car Charger, no.

Daft eh? :roll_eyes:

DJI chargers only work with the engine running, they have a minimum voltage requirement. Your leisure batteries probably won’t be putting out a high enough voltage (even on solar?)

Aftermarket chargers aren’t fussed about their input voltage, they’ll still charge your batteries :slight_smile:

My Mini 2 batteries will just charge from any USB socket, so assuming your van has one of those somewhere you’d be fine.

Seeing as the Mini and Min2 charge from USB could you wire something like this into your system?

Use an inverter for 240v mains power… Simples

That’s not friendly to leisure batteries :slight_smile:

Definitely makes more sense to just step down 12V DC to 5V rather than going 12V DC - 240V AC - 5V DC

The simple USB cable option is by far the best recommendation :slight_smile:

Could always go down the powerbank option, but then you still have to charge that.

As Rich says, don’t overthink it. USB it

I have used an inverter for years for various things.
2x 120ah leisure batteries topped up with solar panel and a 2000w inverter.
Charge phone batteries, camera batteries and run a TV + the Mrs uses her hair drier on occasion.
Never had a problem in last 5 years or so

The inverter I’ve got also has 5v USB sockets as well… Best of both worlds

Yes it does pal sorry it was a quick answer before

You will need a usb-c to usb-c cable as the PD charge is only on the usb-c hope this sheds more light.
