### ⭐⭐⭐⭐⭐ Review
*by M***R on July 28, 2024*

Having been provided with a new router by our internet provider, and also being migrated onto a voice over internet phone service, we decided that we needed a small UPS for the router in order to maintain phone and internet connectivity in the event of power cuts - we live in arural area and power cuts are a fact of life, even if they're not common. I did a fair bit of looking around to see what was available for what prices. I didn't want a cheap, no-name product, but I didn't want to spend the earth either. APC and Eaton seemed to be the best brands out there, and I'm familiar with the products of both companies. They are both "real" companies and supply products backed by proper warranties. In the end, the Eaton won out - largely because the connectors suited our router better (and it was also a bit cheaper). As it was, the 3.5mm barrel connector was still a little bit short and I had to machine away a small amount of the plastic surround to get a more secure connection - that's as much to do with the particular construction of our router, rather than being a fault of the UPS. That aside, it's a very neatly made package and is easy to set up and get running. I haven't yet tested the endurance of it to see how long it will keep the router running, but it does continue to run the router without any glitch or hesitation when I turn of the mains for a few minutes.
