To add more detail, the DJI Battery charger requests 20v and 5A from the USB-PD power adapter.
Not many USB-C cables can handle 5A, and they need an active e-chip to indicate that they can.
So, unless your USB-PD charger and the cable both claim to support 5A, it won't charge at 100W
(I haven't checked, but I think it stays at 20v lower-current if the whole thing can't do 5A.)
If voltage drops significantly below 20v (19.5?) then you can see it drop down the current draw as well.
With the right charger, it really does draw a measured 99W of power -- that's quite a lot!
The whole assembly of batteries and charger can actually overheat itself at 100W and trigger the "three blink" LED code for battery-too-hot-to-charge.
I'm not sure 100W charging is good for longevity, so I've downgraded to a 65W USB-PD for non-urgent charging.
Charging in the drone itself is also cooler/slower at 65W. |
