Best Battery Backup for a Router and Camera for Power Outages
A power outage should not cut the home network and the security cameras at the same moment. A small battery backup keeps the router, modem, and camera alive long enough to stay online, record events, or ride out a short blackout. This guide covers five battery backups for a router and camera, from a compact standby unit to high-capacity mini UPS models with selectable DC voltages. Buyers who want the simplest plug-and-play option, buyers who need multiple DC voltages, and buyers who want maximum runtime each have a clear pick below. The overview table comes first so a decision can be made in under a minute.
Overview of the Picks
| Product | Key Spec | Best Use | Price Tier |
|---|---|---|---|
| UPS Battery Backup for Router Camera DVR, 2600mAh | 2600mAh capacity | Short outages, single router or camera | Budget |
| CyberPower ST425 Standby UPS | 425VA/260W, 8 outlets | Whole desk of network gear on AC power | Budget |
| Mini UPS 6000mAh, 5V/9V/12V Outputs | 6000mAh, selectable DC | Mixed-voltage router and camera setups | Mid-range |
| Mini UPS 8000mAh with USB and DC Ports | 8000mAh, USB + DC | Longer runtime, modem plus camera | Mid-range |
| FTVOGUE Mini UPS 10400mAh | 10400mAh capacity | Maximum runtime for router and camera | Premium |
1. UPS Battery Backup for Router Camera DVR, 2600mAh
UPS Battery Backup for Router Camera DVR, 2600mAh Emergency Power Supply
Capacity: 2600mAh
Type: Emergency power supply
Intended use: Router, camera, DVR
Power source: Rechargeable battery
This is the smallest and most focused unit in the group. It is built for the one job most people actually need: keeping a router or a single camera alive while the grid is down. The 2600mAh cell is enough for short interruptions, and the compact housing is meant to sit quietly next to the gear rather than take up desk space. It suits a renter or a first-time buyer who wants a cheap safety net without rewiring anything.
The caution here is runtime. A 2600mAh battery is a short-bridge design, so it is not the pick for multi-hour outages or for powering a router and several cameras at once. It earned its place as the entry point for anyone testing whether a backup is worth having at all.
Trade-off: Small capacity means short runtime, so this is a stopgap, not an all-evening solution.

2. CyberPower ST425 Standby UPS Battery Backup and Surge Protector
Power rating: 425VA/260W
Outlets: 8
Form factor: Compact
Certification: UL Certified
Type: Standby UPS with surge protection
This is the traditional answer to the question, and the most familiar shape of the category. It is a standby UPS with eight outlets, so the router, modem, and a camera power supply can all plug into one box, and the surge protection covers everything attached. The UL certification is the detail that matters most for a device that will sit plugged in for years. It suits a buyer with a small network shelf who wants one box to handle both outages and spikes.
The limitation is that it delivers standard AC power only, so it does nothing for gear that runs on a DC barrel jack without its own adapter. It is also the bulkiest pick here, which matters in a tight cabinet.
Trade-off: AC-only output means DC-powered cameras still need their own adapters, and the box takes up real shelf space.

3. Mini UPS Battery Backup for Router, 6000mAh, 5V/9V/12V Outputs
Capacity: 6000mAh
Outputs: DC 5V/9V/12V
Compatible with: WiFi routers, security cameras, fingerprint scanners, smartphones
Type: Mini uninterruptible power supply
This is the versatile middle of the range. Three selectable DC voltages mean one unit can feed a 12V router, a 9V camera, and a 5V accessory without a pile of adapters. The 6000mAh capacity is roughly double the entry pick, so it covers longer interruptions and more than one device. It suits a household with mixed gear from different brands, where matching voltages is the real headache.
The caution is that voltage selection has to be set correctly before anything is plugged in, and a wrong setting is a real risk for the connected device. It also depends on the right barrel connector being supplied.
Trade-off: Flexible DC output demands care — the voltage switch must match each device exactly.

4. Mini UPS Battery Backup for Router Camera Modem, 8000mAh
Capacity: 8000mAh
Ports: USB and DC
Intended use: Router, camera, modem
Type: Mini uninterruptible power supply
The 8000mAh model is the runtime step up, aimed squarely at outages rather than blips. The mix of USB and DC ports means it can carry the modem and a camera alongside a phone, which is useful when the outage also takes the phone charger. It suits a buyer who has already decided a backup is necessary and wants enough reserve to keep the network up for a meaningful stretch.
The trade-off is size and charge time: a larger cell takes longer to refill and is less discreet than the 2600mAh unit. Buyers with a single low-draw router may be paying for capacity they never use.
Trade-off: Bigger battery means longer recharge and more bulk than a single-router household needs.

5. FTVOGUE Mini UPS 10400mAh Battery Backup
Capacity: 10400mAh
Type: Mini UPS, DC
Intended use: Routers, cameras
Form factor: Compact
Plug: US Plug
Color: White
This is the highest-capacity pick in the roundup, and the one for buyers who treat an outage as a multi-hour event. The 10400mAh cell gives the longest reserve here for a router and camera pair, and the compact white housing is easier to place than a full-size UPS. It suits a home office or a property with frequent, long blackouts where the network has to stay up.
The caution is that capacity this large only pays off if the connected gear is modest; a high-draw device will still drain it. It is also the priciest pick, so it is overkill for anyone who only needs to bridge a few minutes.
Trade-off: The premium price and large cell only make sense for long or frequent outages.

Before You Buy
- Output type: An AC standby UPS powers anything with a standard plug; a DC mini UPS needs the correct barrel connector and voltage for each device.
- Capacity vs. runtime: Match the mAh rating to the outage length expected — 2600mAh bridges minutes, 10400mAh covers hours of light load.
- Compatibility: Check the router and camera power ratings and plug types before buying, especially for 5V/9V/12V switchable units.
- Device count: Count how many devices must stay up; a single-outlet mini UPS will not carry a router, modem, and camera together.
- Placement: Confirm the unit fits the shelf or cabinet and has room for ventilation, since standby UPS boxes are the bulkiest option.
- Charging: Larger batteries take longer to recharge after an outage, so plan for a full recharge between events.
- Certification: For anything left plugged in permanently, prefer a UL-certified unit such as the CyberPower standby model.
Frequently Asked Questions
-
How long will a battery backup keep a router running?
It depends on capacity and load. A 2600mAh unit covers short interruptions, while an 8000mAh or 10400mAh model can carry a router and camera through a longer outage. -
Can one battery backup power both a router and a camera?
Yes, if it has enough outlets or ports and the capacity to match. AC standby UPS units with multiple outlets and higher-capacity mini UPS models are the usual choices. -
Do I need an AC UPS or a DC mini UPS?
An AC UPS suits standard plugs and surge protection; a DC mini UPS suits gear with barrel connectors and lets the voltage be matched to each device. -
Is a UL-certified UPS necessary?
It is a sensible baseline for a device that stays plugged in year-round. The CyberPower ST425 carries UL certification, which is a meaningful safety marker. -
What happens if the voltage setting is wrong on a mini UPS?
Feeding the wrong voltage to a router or camera can damage it. The setting must be confirmed against the device label before connection. -
Can a battery backup also protect against surges?
Standby UPS units like the CyberPower model include surge protection; most DC mini UPS units focus on backup power rather than surge suppression.
Bottom Line
For most households, the best battery backup for a router and camera is the CyberPower ST425: UL-certified, eight outlets, and simple AC plug-and-play for the whole network shelf. Buyers with mixed DC gear should step up to the 6000mAh mini UPS with selectable voltages, and anyone facing long outages should take the 10400mAh FTVOGUE for maximum runtime.
