And - only for the record - if you really-really want to power it with a “smart” USB -C power source, you can add to it a couple 5.1kOhm resistors:

Or you can use a so-called USB-C decoy pcb.
The Ax lite needs 5V, needs around 8-10 W and comes with a power adapter rated as 2.4A@5V, i.e. 12 W.
Some history, to put things in perspective:
The original USB (1.0/2.0) implementation (as a connection port on a computer) allowed maximum 500 mA@5V.
The USB 3.0 raised that to 900,A@5V
The USB 3.2 raised that to 1.5A@5V.
And the connector was the A type.
The various manufacturers of power supplies (often connected with mobile phone manufacturers) started to make power supplies with 1,2,3A @5V still with the USB A connector and “no questions asked”, if the power supply can give out 3 Amperes, it will give them out.
Then they started to develop the various quick-charging schemes, raising voltage and thus power.
When the good guys developing the USB-C standard came (late as always) managed to make it extremely complex trying to cover all the existing de facto standards, reaching a stupidly high power delivery level (now 5A@48V, aka 240W 
) so they couldn’t risk to fry half the old devices.
Anything more would need a negotiation between the power supply and the powered device, requiring a specific chip on both the power supply and the powered device.
Then they carved an exception for delivering 3A@5V if the presence of the two resistors was found.
So in theory (and also in practice) adding two tiny resistors to the Ax lite is enough (provided that the power supply at the other end of the USB-C cable is fully compliant).
