I have a feeling I'll be buying one of those fancy USB-C amperage/voltage meters. I hit issues with the charging spec on a GPD Pocket (tiny laptop). Its maximum supported charging voltage is 12V, which is now optional in the USB-PD 2.0 standard. So most chargers I see now are 5V/9V/15V Macbook charger for instance is missing the 12V, so it charges slow off that charger since it ignores the 15V rail. Has to fall back to 5V or 9V in theory...
