The only down side of the Mini 4 Pro is the nearly 6 hours it takes to charge the three batteries.
I am looking at getting a 4th battery when funds allow.
I am looking for a much faster way of charging them, advice please.

Actually its 8 hours to charge all three.
I am reluctant to leave them charging overnight, But then I di that with my phone so…
Hi there.
What type of chargers are you using? You need a charger that a provide at least 30W. If you’re just using any old phone charger that you have lying around that will cause the slow charging problem you’re having.
I use this.
I am using the 3 battery DJI charger supplied with the drone.
Connected to a 40W *8 Port multi charger.
" Ziwodiv 8-Port Multi USB Charger Station, USB Charging Hub with LED Display Wall Charger" From Amazon.
I take it that you’ve only got the dji 3 battery charging hub connected to the charger or do you have other devices like your phone charging at the same time? If you have more than one device attached then the total 40w output from your charger will be split across all devices connected.
Yes. Only the battery’s Ok the RC2 as well but that is fully charged in 2 hours. .
With just the DJI 3 battery charger plugged in to the 40W charger. It stiil takes 8 hours to fully charge all three.
I’d suspect the USB charger you’re using either not giving enough power or not succesfuly arbitrating the correct charge rate with the 3 battery DJI charge unit. I use one of these and the charge times are under half those your quoting.

Mini 4 Pro

I kinda figured it out because when I pulled my mini 2 se out of mothballs all the batteries were dead. With a Samsung 15w charger it took all night. Iwhen I got my mini 4 pro 2 weeks ago I used my 45w Samsung charger and it was so much quicker charging the batteries up.
When did DJI stop supplying chargers? As there wasn’t one in with the mini 2 se I purchased 2 years ago in September.
I’m pretty sure my Mavic Mini (i.e. first generation Mini) didn’t come with a charger.
I bought it in Japan and I would have remembered a Japanese DJI plug.
Out of curiosity I looked up the Ziwodiv 40W 8-Port Multi USB Charger Station. It’s your problem !
Although rated at 40W total it can only supply 2.4 Amps maximum per channel. That’s 12 W maximum at 5V on a single channel.
Get one of the linked chargers above and you’ll be fine.

Thank you Westbury.
Very much appreciate you doing the research. That explains it very well.
I only ever used that charger to for a bike lights.
I will order on of the linked chargers.

Make sure you use a USB type C to type C lead between the charger and DJI unit for maximum charge rate. Type A to C will be slower.
Get a lead that states it’s for charging. They have heavier wires and dont restrict the charge.
Something like this:

OK, so I’m late on parade to this…
I see two issues and two solutions
Issues, as has been pointed out, the charger you’re using is sharing the output between the three batteries it’s charging. However, the charger is in it’s self the other issue it’s only 40 watts…
Proposed solution - DJI do a 65w charger
DJI 65W Portable Charger USB-C connector (UK) – DJI Hasselblad
The other way is to charge the batteries out of the hub, not ideal, but as the primary goal is to get three fully charged batteries as quick as possible, then logic says if it takes 2 hours +/- to charge one, but 6-8 hours to charge all three in the hub, then I would be charging them individually when I need the recharger PDQ.
Then when I’m not waiting for them, put them in the Hub and let it do its thing over night. I have a fireproof battery safe for just that.
Result - three fully charged batteries in ~2 hours - or have I missed something?
The thing about modern USB charging is that a bigger charger doesn’t neccesarily mean faster charging. USB devices arbitrate a charge rate between the charger and the device being charged. In essence the charger says to the DJI hub these are the rates I can charge at and the hub says these are the rates I can be charged at and they pick the highest one they have in common,
The 3 battery DJI hub spec:
Model: CHX162-30
Recommended Charger: DJI 30W USB-C Charger or other USB Power Delivery chargers
Input: 5 V, 3 A/9 V, 3 A/12 V, 3 A
Output (USB): 5 V, 2 A
Operating Temperature Range: 5° to 40° C (41° to 104° F)
Charging Time: Three Intelligent Flight Batteries can be fully charged in about three hours.
No harm will be done by having a charger bigger than the hub needs but it won’t charge any faster.
Looking at the spec you might get a very small advantage with a charger up to 36W but higher isn’t neccesary.

Yep, understand that, that’s why three chargers charging three batteries would make for three fully charged batteries faster than using the Hub and a single charger of any size…
How are you going to charge the batteries individually at the same time though to get the speed increase ? The batteries themselves don’t have a USB connector. They can only be charged in the drone one at a time or in the 3 battery charge hub.
Looking at the second Picture here:-
DJI 65W Portable Charger USB-C connector (UK) – DJI Hasselblad
It looks like the cable is plugged into the battery… I wrongly assumed that you could connect direct to the battery…
At this point I think it’s become obvious I’m not too familiar with the detail of DJI drones’ I made the assumption from the picture that you could connect direct to the Battery.
I find it really strange that they/DJI would make a battery that is, on the face of it quite restrictive as far as charging goes.
Also worth mentioning, I’ve been looking into the possibility of making a DJI drone the next new addition to my Hangar. Following this conversation and the lessons learned from it, I’m going to do some more research before I commit!
