Best Refurbished Uninterruptible Power Supplies for Home and Office Use
If you’re looking for a refurbished uninterruptible power supply (UPS) that protects a home office, Wi‑Fi router, and computer from outages and surges, you’ll want options that balance runtime, outlets, and reliability. The following five products represent solid choices for different needs—from compact setups to full home office rigs. They’re especially suitable for buyers who want dependable backup power without breaking the bank, with clear tradeoffs noted for each model.
APC BE600M1 UPS: Compact Backup Power For Essentials
The APC BE600M1 provides short‑term battery power for computers, Wi‑Fi, and routers during outages, with 23 minutes of runtime at 100W. It features 5 battery-backed outlets plus 2 surge-only outlets, offering a compact footprint for a single desk setup. This makes it best for smaller home offices or dorm rooms where compact size and essential protection matter most. A caveat: it’s not ideal for power-hungry setups or home entertainment centers requiring extensive backup time.
APC BX1500M Back‑Ups Pro: Mid‑Size Home Office Power
The APC BX1500M offers 1500VA / 900W of backup power with up to 19 minutes of runtime at a 300W load. It supports essential devices like computers, Wi‑Fi routers, modems, and NAS drives with 10 total outlets (5 battery backup + 5 surge only) along with built‑in surge protection for coaxial and Ethernet ports. This model is best for users who need more runtime and outlets than a compact unit and want reliable performance during outages. It’s less ideal for heavy, high‑power workstations that require sustained power for long periods.
CyberPower ST425: Compact Standby UPS
The CyberPower ST425 is a compact standby UPS with 425VA/260W and 8 outlets (4 battery backup + surge protected; 4 surge protected). It uses a simulated sine wave output, making it suitable for basic home offices, gaming consoles, and broadband routers. It’s best for users who need affordable, space‑saving UPS protection for low‑to‑mid‑power devices. Note that it provides less runtime and no true sine wave output, which some sensitive electronics prefer.
CyberPower CP1500PFCLCD: PFC Sinewave‑Ready UPS
The CyberPower CP1500PFCLCD delivers 1500VA / 1000W with PFC sinewave output and 12 outlets (6 battery backup + 6 surge protected). It includes 2 USB ports (Type‑A and Type‑C) for quick device charging and a multifunction color LCD panel that shows battery and power status. This model is best for users with a larger setup that includes multiple peripherals and USB‑charged devices, offering both strong runtime and modern charging features. A limitation: higher power draw devices reduce backup time, so plan runtimes accordingly.
APC BE425M: Small, Reliable Router‑Saver
The APC BE425M focuses on small electronics with 6 outlets (4 battery backup + surge protection; 2 surge‑only), providing up to 15 minutes of runtime at 100W. It’s best for essential devices like a router, modem, VoIP phones, and compact home office gear. Choose this if you want a minimal footprint with dependable surge protection and short‑term backup during brief outages. A drawback is the limited backup duration for any higher‑power devices.
APC BE1500MS2: Sine Wave For Demanding Setups
The APC BE1500MS2 provides 1500VA / 900W with true sine wave output, AVR, and a 10‑outlet configuration (10 total). It’s designed for homes with power‑sensitive equipment such as gaming rigs, workstations, NAS drives, and smart home devices. Runtime can reach around 73 minutes at 100W, depending on load, making it better for longer outages. It’s best for users who require steady sine wave power and more outlets, but it’s larger and costs more than compact models.
Buying Guide
- Runtime needs: Calculate total wattage of essential devices and choose a UPS that can cover at least 15–30 minutes at your typical load; consider models with 900W–1000W or higher for longer outages.
- Outlets and layout: Determine how many devices you need on backup power. Look for mixed battery backup and surge‑protected outlets, plus surge‑only outlets for less critical gear.
- Power type: True sine wave (or AVR‑enabled sine wave) is preferable for sensitive electronics and modern PCs; standby units may be sufficient for basic routers and modems.
- Data protection features: LCD/LED status indicators, automatic voltage regulation, and USB ports for charging can improve usability and reduce downtime during outages.
- Form factor: Compact units fit small desks; larger towers or mini-towers support bigger setups with more outlets and longer runtimes.
