Thought I’d share this for charging on the “go”
I got a USB C to DC 5.5x2.5mm cable, connected as as normal and it charges successfully using my plug in charger I normally use for my phone. I was surprised!
I also tried my homemade Makita battery adapter to DC 5.5x2.5mm and that works well; and no doubt charges quicker due to it being 18v as opposed to 5v.
