Reliable Backup for Routers, Cameras and Smart Home Devices
Power cuts don’t just knock out the router, they can take down cameras, door access systems and other smart home gear at the same time. The NBS-UPS05W switches to battery automatically with zero-second transfer time, so connected devices keep running the instant grid power drops. It’s built on a 44.4Wh lithium battery, larger than the standard compact mini UPS models, to give real backup time rather than just a few minutes of bridging power.
A High-Current 5A Backup Solution
With a 12V 5A max discharge, the NBS-UPS05W can power 2 to 3 devices at the same time instead of just one. Optional voltage conversion cables are available for 5V, 9V and 12V outputs, so it can match devices beyond standard 12V equipment. It sits flat on a desk with an anti-skid base or mounts on a wall at any angle, and a brushless silent fan keeps it cool without adding noise.
Backup Time for Real-World Loads
Runtime depends on what’s connected. At a light 12V 0.5A load it holds approximately 9 to 10 hours, while at 12V 2A it holds roughly 2 to 3 hours. Heavier multi-device setups will run shorter, so it’s worth checking total connected load against the 5A max output.
Compatible Devices
- WiFi routers, hubs and CPE equipment
- ONT, ONU and gateway devices
- VoIP telephones
- IP cameras and security systems
- Door access control and smart home controllers
Key Features
- 12V 5A max discharge, enough to power 2 to 3 devices at once
- 44.4Wh lithium battery for extended runtime
- Optional 5V/9V/12V conversion cables for broader device compatibility
- Brushless silent fan for heat dissipation
- 4 LED lights showing battery level
- Anti-fire ABS housing, wall-mountable or desktop use
Smart Protection Built In
The NBS-UPS05W runs on a smart chip management system with a dedicated battery protection board, covering over-current, over-voltage, over-discharge, over-charge, short-circuit and high-temperature protection. It carries CE, FCC, ROHS, LVD, IEC62368 and UN38.3 certification, and comes with a 12-month warranty.
Looking for a High-Current Smart Home Backup?
The NBS-UPS05W is built for setups where one device isn’t enough, backing up routers, cameras, VoIP phones and smart home controllers together through a single unit. Its larger battery and 5A output make it a fit for households and small offices that need more than a basic single-device mini UPS.
