APC UPS Battery Backup & Surge Protector BE600M1
The APC BE600M1 Back-UPS provides 600VA / 330W of battery-backed power with seven total outlets. Five of these outlets are equipped for battery backup and surge protection, while two outlets offer surge protection only. It includes a USB charging port for mobile devices, making it suitable for small home offices or essential electronics during outages. Runtime varies with load; expect longer backup times at lower power draw and shorter times as devices draw more power. The unit supports safe shutdown during longer outages by preserving connected equipment.
Amazon Basics UPS Battery Backup & Surge Protector 600VA/360W
This standby UPS offers 600VA / 360W with eight outlets, split between battery-backed and surge-protected options. It’s designed for home networks, IoT devices, and home entertainment setups. Backup runtimes scale with load, often providing adequate time to save work and shut systems down during short outages. The compact form makes it easy to place near a modem/router, gaming console, or desktop computer while protecting sensitive electronics from power surges.
CyberPower CP1500PFCLCD PFC Sinewave UPS
The CyberPower CP1500PFCLCD delivers 1500VA / 1000W with a pure sine wave output suitable for active PFC and conventional power supplies. It features 12 outlets (six battery-backed and six surge-protected), a right-angle NEMA 5-15P input, and a five-foot cord. Enhancing usability, it includes two USB ports (Type-A and Type-C) for fast charging. The LCD panel provides real-time battery and power condition details and can tilt up to 22 degrees for easier viewing, helping users monitor status and schedule maintenance or shutdowns.
Amazon Basics UPS 800VA/450W

It’s positioned for larger home networks, AV setups, and gaming consoles that require more power and protection during outages. Runtime scales with device load; expect longer operation for lighter setups and a quick window to gracefully shut down higher-power equipment during longer outages. The unit aims to balance capacity and affordability for mid-sized applications.
Liebert PST5 UPS – 660VA/400W
The Liebert PST5 combines 660VA / 400W standby power with eight outlets, including a mix of surge-only and battery-backed options. It also offers surge protection for network data lines (RJ45) and an LCD display for easy monitoring. Widely spaced transformer outlets help accommodate bulky plugs without blocking adjacent outlets. This model suits small to medium office setups, home media centers, and devices that need reliable protection against power disturbances with visible status information.
Buying Guide: Key Purchase Considerations
- Power capacity and runtime: Match VA/W ratings to your total load. Heavier setups (desktops, NAS, AV gear) need higher VA and longer runtime, while basic routers and modems require less.
- Output waveform: Pure sine wave (or simulated sine wave with high fidelity) is important for sensitive electronics and active PFC power supplies. Cheaper units may provide simulated sine wave; verify compatibility with your devices.
- Battery backup vs. surge protection balance: Assess how many outlets you need for backup power versus protection-only outlets. Some models emphasize battery-backed outlets; others prioritize surge protection across all ports.
- Connectivity and management: USB ports for charging and software that can automatically shut down equipment during outages are valuable for devices with frequent power interruptions. LCD panels help monitor status in real time.
- Protection features: Look for data-line protection (Ethernet, coax, or RJ-45/11) to guard network equipment. Audible alerts and automatic shutdown software can prevent data loss.
- Form factor and placement: Consider tower versus compact designs. Taller units may block nearby outlets, while compact models fit into tighter spaces near PCs or entertainment centers.
- Warranty and service: A longer warranty and responsive support can reduce total cost of ownership, especially for devices relied upon for uptime and data integrity.
These options provide a range of capacities and features for different 120V power needs. When selecting, prioritize the devices that represent your critical load, your available space, and your preferred level of automatic protection and shutdown capability.
