Long Battery Charging Time

[Marty Markoe]

Received new Mini5 Pro Fly More Combo Plus with 3 Extended batteries. Started charging 12 hours ago. Only the battery nearest the USB cable is fully charged with 4 solid green lights. The middle battery shows 2 lights, one of which is flashing. The 3rd battery shows 3 solid lights with USB cable disconnected.

Is this long charging time normal???

I don’t know about the plus batteries, but I’d be wondering what is going on if it were the standard batteries.
Are you sure the power supply you are using is powerful enough? Can the USB cable carry that power? I ended up with a 100w from Anker, with 2 outputs. Use one output to the charging hub with 2 batteries in it, the other to the drone with the 3rd battery in it. Get all 3 charged inside an hour.

This is not normal and time to diagnose. Try different cables, different power source and move the batteries that didn't charge to the slot that did charge the one.You can also insert the battery into the drone and charge with the USB cable to see if the battery will charge. It will take a little longer but within an hour or so.

What is the power rating of the charger you're using, and is it a PD charger?

Use factory supplied cables. If you grabbed a spare from another appliance be aware that there are Data cable vs Charging compliant data cables. You shouldn't substitute the data for charging. Like others have said look at the OE charger specs and be sure the one you are using now meets the minimum output shown on the OE wall
charger. Also, don't charge using your laptop USB port as a substitute for the OE charger

Thank you to all for your suggestions. Need to use a more powerful charging unit not the computer USB cable.

Bingo... I believe DJI suggests using at least a 30w charger for their quick charging times.

Yeah, that would be it for sure! Not only is the USB (most likely A, not C) port not Power Delivery protocol, it's very likely limited to 2.5W of power. Computers are not USB power banks.

You need a good PD charger, I'd recommend getting something at least 100W, and if multiport with support for 100W on one of the ports.

Then you can charge up to 3 batteries together in about an hour.
