These UPSs are perfect for cable modems, access points, cordless phone base stations, etc. This one is in good working condition. I put in a new battery and it's up and running.

Best value for a compact Y/C separator and TBC
These compact little units do a good job of converting composite video to Y/C separated video (i.e. S-Video). The internal TI decoder chip uses a 5-line adaptive digital 2D comb filter, giving you full bandwidth on both the chroma and luma channels, unlike the simple notch filters often built in to older devices (and even some newer ones!). You'll notice better resolution and fewer dot-crawl artifacts as a result. As a bonus, there's even an FPGA that digitally time base corrects the signal prior to converting back to analog. Perfect for VCR signals. It's not the widest range TBC, but worked fine for the vast majority of tapes I tried. Did I mention it's 10-bit?

Excellent for Low Power Devices
This is a good basic UPS for low power, 2-prong devices (e.g. router, cable modem, cordless phone base station). Because it it optimized for low power, it's more efficient than bigger units, which would be a waste in this scenario.
I bought a used unit and the battery was still usable despite being six years old. That implies it has a good charging strategy. Output is a modified square wave but it works just fine with wall-wart power supplies and even an LED lamp.
