Charging Issue

[crackruckles]

Hi guys,


I have recently bought a drone and a solar powered backpack with a battery and want to take them with me on holidays to Iceland however the drone charges it takes about 18 hours each time which is way to slow.

Here is the specs of the solar backpack's battery



output: 12V/4A , 14V/3.5A , 19V/3A


The drone requires the following input



13/26V 9A


I was wondering if there is any kind of converter i could build or buy that would make this work?

Off topic I know, but let us know how it goes when you go through customs carrying a drone. Could be interesting.

Maybe you are trying to charge the big battery with a little solar panel on a cloudy day?
The output from the battery (at noon in the Sahara Desert (on the equator of earth) on a sunny day?) is only about 3.2A. The car power supply for the drone needs an input of 9A. So if the solar thing is making its maximum output (I doubt it) then the charge time is almost 3 times longer than normal.
