It's only for the gateway. Anything else I might want a UPS for is the 
other side of the house. 

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.
