It is the gateway in the house, not the sensors in the garden that I want a UPS for. It's not a Davies Console - it's an Ecowitt so it doesn't have any built-in batteries. I see some people in WXForum are using a power bank. That might be the right route for me to go - I see the power connector is USB-C - so will look in that direction.
