A right-angle, five-foot power cord reduces cord clutter, and two USB ports (Type-A and Type-C) offer quick charging for phones and tablets. Its color LCD panel gives real-time battery and power condition updates, helping users prevent downtime.
APC BX1500M UPS
The APC BX1500M offers longer runtimes for larger setups, including a PC with multiple monitors and a router. With 10 outlets, five provide battery backup while five are surge-protected, plus 1 GB network dataline protection and a six-foot power cord. The unit supports PowerChute management via a dedicated data port for Windows, with guidance on Mac using built-in energy settings. This balance of backup vs. protection makes it a strong option for households looking to safeguard a fridge with smart features and connected devices.
APC BE600M1 Back-UPS
The BE600M1 provides fundamental UPS backup with 600VA/330W capacity across seven outlets, including five backed by battery protection and two surge-only outlets. It includes a USB charger port for mobile devices, helping maintain essential communication during events.

Its USB-enabled communications and energy-efficient design make it a reliable standby for critical appliances, networking gear, and small office systems. This standby UPS is a solid option when space is a consideration but reliable power for a refrigerator during outages remains a priority.
Buying Guide: Key Purchase Considerations
- Capacity and runtime: Choose a unit with enough VA/W rating to support your refrigerator and any connected devices for the expected outage duration. For single-appliance protection, a 600–1000W range can be sufficient; for added devices or longer outages, 1500VA or higher is beneficial.
- Output waveform: For smart refrigerators and devices with active electronics, a pure sine wave (or PFC sinewave) UPS delivers cleaner power and safer operation than a simulated sine wave.
- Outlets and layout: Ensure the UPS provides enough battery-backed outlets for the fridge and any essential peripherals, plus surge-only outlets for other devices. Wider outlet spacing helps accommodate bulky plugs.
- Protection features: Look for surge protection, data-line protection (network/USB), and a clear LCD or app-based status readout. A management software option can help with scheduled shutdowns and alerts.
- Battery type and lifespan: LiFePO4 batteries offer longer lifespans and more cycles than traditional lead-acid, reducing replacement frequency and total cost of ownership.
- Ease of use and maintenance: Consider models with easy-to-replace batteries or service options, clear indicators of battery health, and simple reboot procedures after outages.
- Form factor and placement: Tower or compact designs fit homes with limited space. Some units include built-in cooling and quieter operation, useful for kitchen installations.
- Warranty and support: A longer warranty and accessible customer support are valuable if you rely on backup power for essential appliances.
When selecting a backup battery for a refrigerator, weigh how many devices you want to protect, the typical outage duration in your area, and whether you prefer traditional lead-acid or LiFePO4 battery chemistry for longevity. The models above cover a range of capacities and configurations to accommodate different household needs while prioritizing safe, clean power for your fridge and connected devices.
