5v 0.6A power - You can use a USB DC barrel cable
Reviewed in Australia on 16 June 2021
It's worth noting that this switch comes with a 5v 0.6A power brick. This is within USB power spec, so you can power this over USB as long as you have a USB to DC Barrel connector cable.
The exact size DC barrel end it takes is 3.5*1.35mm, but it will also fit a 4.0*1.7mm.
You can use a "LELO" USB to DC barrel cable like this one which has a 3.5*.1.35mm DC barrel end - https://www.amazon.com.au/gp/product/B07DCK76FP
or a PSP power cable like this which uses a 4.0*1.7mm DC barrel cable - https://www.amazon.com.au/4-0mm-1-7mm-Power-Adapter-Charger/dp/B07P71JHYK/
