WattBox WB-OVRC-UPS-350-6 Compact 6-Outlet 350VA UPS Battery Backup

Compact UPS Backup for Low-Power Essentials

This compact 350VA UPS is built for small devices that keep a home or light business system running, such as a modem, router, smart home controller, small network device, or low-power AV component. It is a good fit when you need battery backup in a tight space and a full-size UPS would be too large.

The main value is simple: protect the small devices that often cause the most frustration when power flickers. If the internet drops, a controller shuts off, or a small AV device hard reboots, the whole system can feel broken. This UPS helps reduce those quick power-related interruptions.

Best Use Cases

• Router and modem backup: Helps keep basic internet equipment running during short power outages or quick power flickers.
• Smart home systems: Useful for small controllers, hubs, bridges, and other low-power smart home devices.
• Structured wiring cans: Compact size makes it a better fit for tight wiring cabinets and in-wall storage areas.
• Behind-TV installs: Good for small streaming devices, media players, or other low-power AV components.
• Small network setups: Can help protect low-power switches, access point controllers, or other supporting network devices.

Who Should Buy This?

This is a good choice if you need a small UPS for essential low-power equipment and want something compact enough for tight installations. It makes sense for homeowners, smart home users, AV installers, IT companies, and low-voltage professionals who need simple backup power for small devices.

It is especially useful when the goal is not long runtime, but stability during short outages, brownouts, and quick power interruptions.

Who Should Not Buy This?

This is not the right UPS for high-load systems, large AV racks, PoE-heavy security systems, large NVR setups, servers, desktop workstations with high power draw, laser printers, heaters, or amplifiers.

It is also not the right choice if you need every outlet to provide battery backup. This model has 6 outlets total, but only 3 outlets provide UPS battery backup. The other 3 outlets provide surge protection only.

Compatibility Notes

• Power capacity: Rated at 350VA / 210W.
• Outlet layout: Includes 6 total outlets: 3 battery-backup outlets and 3 surge-only outlets.
• Power type: Standby UPS topology with simulated sinewave output.
• OvrC support: OvrC cloud management is available when paired with compatible WattBox IP power products.
• Install locations: Compact form factor works well in tight spaces such as structured wiring cans, behind furniture, or near small AV/network gear.
• Power requirement: Designed for use with a properly grounded 15A outlet.

Installation Considerations

Before installing this UPS, decide which devices actually need battery backup. The most important devices should go into the battery-backup outlets, usually the modem, router, controller, or small network device. Less critical devices can use the surge-only outlets.

Keep the load realistic. This is a compact 350VA / 210W UPS, so it should be used for low-power electronics, not larger equipment. If the connected devices draw too much power, runtime will be short and the UPS may not be the right fit.

For structured wiring cans or behind-TV installations, make sure there is enough physical space, airflow, and safe cable routing. Do not bury the UPS in a sealed or overheated area.

Runtime Expectations

Runtime depends on the connected load. The manufacturer lists about 7 minutes at half load, but lighter loads may run longer and heavier loads will run for less time.

For this type of UPS, the goal is usually to ride through short outages, prevent quick device resets, and keep essential low-power gear stable. It is not meant to run a full system for hours.

Good Products to Pair With This UPS

• WattBox Power Solutions for compatible managed power products and larger WattBox options.
• Power Management Solutions for UPS, surge protection, and power planning.
• UPS Battery Backup to compare larger UPS models and runtime options.
• Surge Protectors & Smart Power Strips for additional protection where battery backup is not needed.
• Network Switches if you are protecting small network equipment.
• Access Points if your Wi-Fi system depends on network uptime.
• Wi-Fi Mesh Systems for home and small business wireless coverage.

Need Help Choosing What to Plug Into It?

If you are not sure whether this compact UPS is enough, send us the devices you want to protect. We can help you decide what should go on battery backup, what can stay on surge-only protection, and whether you should step up to a larger UPS.

How many outlets provide battery backup?

This model has 6 total outlets. Three outlets provide UPS battery backup and surge protection, while the other three outlets provide surge protection only.

Is this good for a router and modem?

Yes. This is one of the best use cases for this compact UPS. A router and modem are usually low-power devices, and keeping them online during short outages can help reduce internet interruptions.

Can I use this for an NVR or PoE switch?

It depends on the power draw. This UPS is rated at 350VA / 210W, so it is better for small, low-power devices. Larger NVRs, PoE switches, or camera systems may need a higher-capacity UPS.

Does this UPS provide pure sinewave power?

No. This model uses simulated sinewave output. It is mainly intended for small electronics such as routers, modems, smart home controllers, and low-power AV or networking devices.

How long will it keep devices running?

Runtime depends on the connected load. The manufacturer lists about 7 minutes at half load. Lighter loads may run longer, while heavier loads will reduce runtime.

Do I need OvrC to use this UPS?

No. It can be used as a compact UPS without OvrC. OvrC cloud management becomes useful when the UPS is paired with compatible WattBox IP power equipment.

Can this fit inside a structured wiring can?

Yes, that is one of the intended use cases. Its compact form factor works well for tight spaces, but you should still confirm dimensions, airflow, and cable clearance before installation.

What should I avoid plugging into this UPS?

Avoid high-draw devices such as heaters, laser printers, large amplifiers, power tools, and large computer or server setups. This UPS is designed for low-power essential electronics.
