This is a USB charger with a DC input, you can run it off batteries or an external power supply (including USB-C power supplies, for example for laptops).
It will talk USB QC and USB-PD, and will step up the voltage- so a 12V source can run a full power 20V USB-C PD source. If step up is not required, there is a dual version without this feature
It's got an aluminium case and a pair of USB-A QC and USB-C PD ports.
The pair of USB-A and USB-C ports can only provide higher power to one output at once, if both are plugged in, the output will be 5V. A green light indicates that a higher voltage is being used.
It can deliver up to 100W on the USB-C PD port: with an input voltage over 10V, it's possible to charge a laptop at full speed. It will work with voltages as low as 3.7V, however the output power is limited to 10W
This can allow USB ISDT AA battery chargers to run at full power. USB Splitter cables are available to allow multiple chargers to run from a single port. 4 chargers per port should be sustainable at full power.
