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, however it will only use voltages lower than than the input voltage. If given a 12V input this will work at full power for USB QC, however you won't be able to charge a laptop at full speed with it - this will need at least 20V. If you need to step up the voltage, there is a single variant which can do this.
It's got an aluminium case and 2 pairs of USB-A QC and USB-C PD ports.
Each 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 red light indicates that a higher voltage is being used on that port.
It can deliver up to 100W on each USB-C PD port: with an input voltage over 20V, it's possible to charge 2 laptops at full rate.
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
