For small loads it’s perfectly fine. Big loads would push the duty cycle of the transformer and the excess heat would be an issue but for small loads like a router or NUC it’s perfectly adequate.
Anything bigger like a desktop PC or server in active use I’d upgrade to a bigger UPS to ensure a better duty cycle on the components, but that’s also an additional expense.
