Standby UPS for home office and networking
The CyberPower SL700U is a standby uninterruptible power supply rated at 700 VA and 370 W. It protects computers, gaming consoles and home networking equipment from outages and surges. Eight NEMA 5-15R outlets provide five battery-backed sockets and three surge-only sockets. Two shared USB Type-A ports deliver up to 2.4 A for phones and tablets.
Input range and simulated sine wave output
The unit accepts an input voltage window of 96 to 140 V at 50 or 60 Hz. Output is a simulated sine wave at 120 V ± 5 %, which suits most switch-mode power supplies but may not support active PFC units or sensitive medical gear. Surge protection includes EMI and RFI filtration plus an internal circuit breaker. Recharge takes eight hours after a full discharge.
Runtime at load determines suitability
At full 370 W load the battery lasts two minutes; at half load it runs for nine minutes. This window is sized for a graceful shutdown rather than extended operation. The sealed lead-acid battery is not user-replaceable. Buyers needing longer runtimes or pure sine wave output should consider other topologies.

Questions about this item
How do I decide between the 700 VA rating and the 370 W rating when sizing my load?
Use the 370 W figure for real equipment draw; the 700 VA value only describes apparent power capacity.
What does the 370 W output actually support during a blackout?
It powers connected gear for about 2 minutes at full load or 9 minutes at half load before shutdown.
What does the shared 2.4 A USB limit mean for charging two phones at once?
Both ports together supply a maximum of 2.4 A, so two devices split that current rather than each getting 2.4 A.
