Power interruptions don't give you time to figure out a plan. When the lights flicker, a UPS gives your computer, router, or networking gear the critical power to shut down cleanly or ride out the outage. In the UPS critical power category, two used units stand out for very different reasons: the Tripp Lite SMART1500LCDT offers bigger capacity and more outlets but no batteries, while the APC Back-Ups Pro 1000 comes with a battery carrier and a much lower price. Which one makes sense depends on what you're protecting and how much you're willing to spend.
Quick Verdict
If you need maximum output, ten outlets, and surge protection in a tower or rack mount, the Tripp Lite SMART1500LCDT is the unit to choose, provided you can handle the battery setup. If you prefer a lower upfront cost and eight outlets are enough for your gear, the APC Back-Ups Pro 1000 with its battery carrier is the practical route.

Where Each Product Wins
Tripp Lite SMART1500LCDT wins on capacity and flexibility. With 1500VA and 900W of output, it can handle a more substantial load than a typical small UPS. Ten outlets give you plenty of room to plug in a PC, monitor, external drives, and network equipment. The tower/rack-mountable form factor fits neatly into a home office or network closet. The surge protection feature adds an extra layer of defense.
APC Back-Ups Pro 1000 wins on upfront cost and the included battery carrier. It's the less expensive of the two, and the battery carrier gives you a mount for batteries right out of the box.
Product Notes
Tripp Lite SMART1500LCDT 900W 1500VA Smart LCD UPS Back Up Tower, No Batteries

At $175.00, the Tripp Lite SMART1500LCDT is the higher-priced unit in this pairing, and it's easy to see why. The 1500VA / 900W rating provides plenty of capacity for a desktop computer, monitor, and multiple peripherals. The ten outlets allow you to connect more gear than most comparably sized UPS units, and the surge protection helps shield your equipment from voltage spikes. The black tower can stand on a desk or be mounted in a rack, giving you placement options. The main drawback is the lack of batteries: the title clearly states 'No Batteries,' so you'll need to add compatible batteries before it can deliver backup power. That adds time and cost, but if you already have batteries or are prepared to buy them, the Tripp Lite has the muscle for critical setups.
APC Back-Ups PRO 1000 BR1000G 8 Outlets UPS w/Battery Carrier QTY

The APC Back-Ups PRO 1000 BR1000G takes the opposite stance: it's the lower-priced model at $64.99, and it comes with a battery carrier, so you have a dedicated mount for your batteries. Eight outlets give you room for a computer, monitor, router, and a few accessories without crowding. Since it's a used unit, you're getting a familiar model name and the core UPS functionality. The trade-off is that you have fewer outlets than the Tripp Lite, so if your desk setup is heavy on peripherals, you might run out of space. But for a straightforward, lower-cost setup in the UPS critical power space, this APC makes it easy to start protecting your gear without a big outlay.
Final Choice by Use Case
Choose the Tripp Lite SMART1500LCDT if you need 1500VA capacity, ten outlets, surge protection, and a tower/rack-friendly form, and you're okay adding batteries yourself. Choose the APC Back-Ups Pro 1000 if eight outlets and an included battery carrier are enough for your setup, and you want to keep your upfront spending down.
