SKE SMART KEY ENERGY SKE SK425 425VA/240W UPS Battery Backup & Surge Protector

Bottom line: The SKE SK425 425VA/240W UPS Battery Backup & Surge Protector ($82.99 on Amazon as of 2026-10-21 04:22 UTC, orderable but not in stock): 425VA/240W keeps a PC, router, modem and NAS powered through short outages; main trade-off: 240W output caps loads, too little for gaming PCs or high-draw setups.
