Choosing a UPS for critical power starts with one question: do you need more capacity and rack compatibility, or do you want a cleaner battery chemistry at a lower price? The Goldenmate Back-UPS 1000VA/800W and the Eaton 5P1500R 5P 1U 120V Rack UPS answer that question differently. One runs on LiFePO4 cells with a built-in BMS; the other is a higher-output rack UPS. Here is how they compare.
Quick verdict
Pick the Eaton if your critical power load is higher and your equipment is rack-mounted. Pick the Goldenmate if you prefer battery chemistry over raw output and are comfortable with refurbished condition. The price spread runs from $136.80 for the Goldenmate to $239.90 for the Eaton, so the decision comes down to output, condition, and how much cosmetic wear you can accept.

Where each product wins
- Goldenmate Back-UPS 1000VA/800W: The battery chemistry and wide temperature tolerance make this the better pick when environmental conditions are less controlled. The built-in BMS adds another layer of protection.
- Eaton 5P1500R 5P 1U 120V Rack UPS: Higher capacity and a rack-friendly design make this the better pick for a rack setup. The audible alarm, cold start, and LED display are practical extras.
Goldenmate Back-UPS 1000VA/800W LiFePO4 Battery Backup UPS
With EV-grade LiFePO4 cells and a self-developed BMS offering six protections, this UPS is aimed at buyers who want a more stable battery chemistry. It handles instantaneous high-current discharge and is rated for stable output from -20°C to +60°C, which makes it a good pick for a room where temperatures are not always controlled. The trade-off is that its 800 W output is the lower of the two in this comparison, so it works best when the load stays modest. If that fits your setup, this is a sensible critical-power backup.
Eaton 5P1500R 5P 1U 120V Rack UPS
The Eaton is the higher-output side of this comparison. The five 5-15R receptacles, together with the audible alarm, cold start, and LED display, make it a practical choice for equipment that needs to stay up when power dips. It is sold as used, and the exterior shows scuffs and scratches from storage and regular use, so it will not look new. A 30-day warranty is included, which is useful given the used status. This is the side to pick when your gear lives in a rack and you need more headroom than the Goldenmate offers.
Final choice by use case
Choose the Goldenmate Back-UPS 1000VA/800W if you want a lithium battery, a certified-refurbished label, and the lower end of this price spread. Choose the Eaton 5P1500R if you need higher capacity, more receptacles, and a rack-oriented UPS, and you can accept cosmetic wear.
