Tales from a Ventilation Lunatic

The ecarc ridgid bTtery adapter pictured last page, is a bit different than some no name brand which arrived later.
The latter no brand name arrival has a smidge of solder connecting low strand count stiff 12awg to contact, where as ecarc had a12awg to a barrell crimp, to which i added a smidge of solder, and heatshrink.

Here is a nice 3 amp, 8 to 23v dc to USB-C power converter.

I do have a portable single 18650 usb supply/18650 charger, but my healthiest 18650 can only get my phone from 10% to ~55%, at no more than 1.56 amps, intially. Charge rate falls off.pretty quickly

The android phone itself an charge uoto 1.68 amps to around 85% before amps.start tapering, with a powerful enough source and short quality usb c cable.

Still deciding how to mount it, and wire it up. Will be a parasitic draw if left connected.

My ciggy plug USB power supply, did not let out its magic smoke, when fed 20v, but it.did not work either, requiring me to use bucker inline to charge Android phone via ridgid 18v battery or.ridgid wall wart.

So the unit linked above, can eliminates a lot of bulk, weight, and wasted wattage.
