Query: Works great with all APC Battery backups.

This is a great product. Plus it works with all APC UPS's, and does not void any warranties on your APC UPS. It is nicely designed so you can plug in lots of things, including large power bricks. I have even used the mounting holes on the back with cable ties, to mount it to racks and shelves. This product could be made even better if it had a 12 or 15 ft power cord instead of 6 ft.
