Best UPS battery backups when the NAS must stop and the network must stay on
Our pick
APC BE850G2
Start with APC BE850G2 for six modest essential connections, a supported USB shutdown route and quiet routine alarms with a low-battery warning. BE600M1 covers five connections at a lower watt ceiling. BR1000MS adds sine-wave battery output and boost-and-trim regulation. EC850LCD is worth considering when its computer-following surge outlets are useful, but they are the wrong bank for always-on networking. Check exact host support, total load and runtime before choosing any of them.
BE850G2 combines six battery-backed AC sockets, separate USB host communication, supported user battery replacement and Quiet Alarm behavior that retains the low-battery warning. It suits a compact network setup within 450 W and 850 VA when the NAS supports this exact UPS and its step-approximated output. Check adapter spacing and runtime at the actual load. Two charging USB ports share 2.4 A and do not replace the data connection. A supported host can still be configured to turn off the whole UPS, so inspect that setting before relying on the router to stay on.
Why it fits this need
- The complete power and data path stays connected
- The exact host can execute the intended shutdown sequence
- Main trade-off
- 450 W and 850 VA limits, with step-approximated battery output.
- Choose APC BE600M1 instead when
- Five essential plugs are enough within 330 W and 600 VA, with exact NAS support confirmed. Quiet Alarm and supported APCRBC154 battery service remain useful. It has one charging port, separate from data USB. The initial charge instruction is 24 hours, so arrival day is not a reason to assume a fully prepared battery.
More reasons behind this pick
- Warnings and battery service fit the household
Choose backup for a NAS, router and separate network devices. Count the backed-up plugs, verify shutdown support and plan what stays on after the NAS stops.

What matters in practice
How to choose for this need
Draw what must stay powered after the NAS has finished protecting its data, then check whether the shutdown command preserves that plan.
One home network can need more plugs than it first appears
A NAS, ONT, router, separate switch and wireless access point make five AC connections. A second NAS makes six. BE600M1 backs five sockets, while BE850G2, BR1000MS and EC850LCD each back six. Count the actual equipment before buying. A combined router and modem changes that example, and a large adapter can block an adjacent position. Check total watts and VA independently of the socket count. A device moved to a surge-only bank will stop receiving power during the outage, even when the UPS still has battery energy available.
The shutdown signal needs its own route
A charging USB socket supplies power to a compatible device. A host communication port reports the UPS state to supported software. These finalists provide a separate data connection, but that alone does not establish support for every NAS. Synology’s documented network UPS arrangement also requires switches or hubs along the signal path to stay powered. A NAS receiving its warning over the network may lose that warning if the intervening switch is on a surge-only socket. Verify the exact NAS, UPS and software combination, then test the documented shutdown procedure with the real network layout.
Stopping the NAS and stopping the UPS are different decisions
Synology DSM documents Standby Mode, which stops services and unmounts volumes. It also offers an option to shut down the UPS, with behavior depending on the model and settings. If the UPS turns off its battery output, a router sharing that supply cannot keep working just because the NAS is now safe. Decide whether the requirement is a clean storage shutdown, continued local networking, or both. Do not infer independent outlet groups from the number of sockets. Check restart settings too, since returning utility power does not by itself prove that every connected device will resume its previous job.
Energy-saving sockets can conflict with an always-on household
EC850LCD has three ECO-controlled surge-only sockets that follow its documented USB-host arrangement. ECO is off by default. When enabled, absent or switched-off host behavior can remove power from those controlled sockets, making them useful for optional desk peripherals. That same dependency is inconvenient for a router used by other people after the computer stops. Put always-on equipment on the correct battery-backed bank and verify the setting. The ECO feature does not extend backup to its controlled sockets or establish a low-load shutdown rule for the battery bank.
A bedroom shelf changes the warning and maintenance choice
BE600M1 and BE850G2 document Quiet Alarm behavior that suppresses routine battery beeps while retaining a low-battery notification. EC850LCD’s muted mode also suppresses the low-battery alarm, so choose another reliable way to receive the warning before silencing it. None of that establishes a fan or electrical-noise ranking. APC documents user replacement for the selected cartridges, while the EC manual assigns battery replacement to qualified service personnel. That service difference matters after years in a shared room. Before another outage, allow for the actual recharge condition rather than repeating a full-battery runtime assumption.
What this comparison cannot tell you
- No universal NAS compatibility or automatic restart promise.
- No runtime is extrapolated from VA, watts or outlet count.
- Local network backup cannot guarantee the internet provider remains available.
- No independently switched battery banks are established for these finalists.
- No medical or life-support equipment recommendation.
4 options
Our pick and alternatives
APC, BE850G2
APC BE850G2
Useful when a compact desk or network shelf needs six backed-up AC connections, plus phone charging that does not occupy another socket. Its two USB-A chargers share one 2.4 A budget, and a separate data connection handles supported host communication. Quiet Alarm retains the final warning. The sixth socket solves a connection shortage only if the adapters fit and the complete load stays within 450 W and 850 VA.
Winner whenBE850G2 combines six battery-backed AC sockets, separate USB host communication, supported user battery replacement and Quiet Alarm behavior that retains the low-battery warning. It suits a compact network setup within 450 W and 850 VA when the NAS supports this exact UPS and its step-approximated output. Check adapter spacing and runtime at the actual load. Two charging USB ports share 2.4 A and do not replace the data connection. A supported host can still be configured to turn off the whole UPS, so inspect that setting before relying on the router to stay on.
Decisive facts
- Six battery-backed and three surge-only sockets.
- Separate USB data, two charging ports and Quiet Alarm mode with low-battery warning.
Trade-off
450 W and 850 VA limits, with step-approximated battery output.
APC, BE600M1
APC BE600M1
A compact option for a supported computer or NAS sharing power with a few network devices. Its separate USB communication port can support the host shutdown routine, while five AC sockets receive battery backup. The user-replaceable cartridge gives it a service route that BE425M lacks. Keep the complete load below both ratings and configure the host explicitly, since a data port alone does not establish NAS compatibility.
Choose instead whenFive essential plugs are enough within 330 W and 600 VA, with exact NAS support confirmed. Quiet Alarm and supported APCRBC154 battery service remain useful. It has one charging port, separate from data USB. The initial charge instruction is 24 hours, so arrival day is not a reason to assume a fully prepared battery.
Decisive facts
- Five battery-backed and two surge-only sockets.
- Separate USB data and one 1.5 A charging port.
Trade-off
330 W and 600 VA limits, with step-approximated battery output.
APC, BR1000MS
APC BR1000MS
A useful step up when the difficult part is six essential connections and an equipment maker’s sine-wave requirement, rather than a desk drawing more than 600 W. Boost and trim AVR cover supported low and high utility-voltage conditions. Two charging ports leave AC sockets free for equipment, but share 15 W. Check the host shutdown path and both output limits before treating the unit as a complete NAS and network plan.
Choose instead whenThe equipment requires sine-wave battery output or the power plan needs boost and trim AVR. Six backed-up sockets share 600 W and 1000 VA. Check the exact transfer requirement, host compatibility and documented 16-hour recharge. The shared 15 W charging ports do not establish a laptop charging replacement. Conflicting dimensions in the current manual are not used to promise shelf fit.
Decisive facts
- Six battery-backed and four surge-only AC sockets.
- Sine-wave battery output, boost and trim AVR and 8 ms maximum transfer.
Trade-off
600 W and 1000 VA ceilings still apply to all six backed-up sockets.
CyberPower, EC850LCD
CyberPower EC850LCD
A compact six-connection backup with a separate choice about optional desk peripherals. Three surge-only ECO sockets can follow the documented USB-connected computer arrangement when the feature is enabled. Keep the household router on a suitable battery-backed socket if it must stay on after the computer is off. ECO starts disabled, and its computer-following behavior does not make those three controlled outlets battery-backed.
Choose instead whenSix essential sockets are needed and three optional desk peripherals should follow a supported USB-connected computer. ECO defaults off and controls surge-only sockets, which never supply outage power. Keep the router and NAS on the battery bank. Muting suppresses the low-battery alarm too, and the manual assigns battery replacement to qualified service personnel.
Decisive facts
- Six battery-backed plus six surge-only sockets, with three surge sockets ECO-controlled.
- ECO defaults off and uses the documented USB-host arrangement.
Trade-off
ECO-controlled outlets are surge-only and unsuitable for an always-on backup role.
