Yuuki Power Mini UPS for Wifi Router, USB 5V⎓3.6A DC UPS 12V⎓2A Battery Backup

Who this mini UPS is best for

• Home networking backup (modem/router): If your main goal is staying online during brief outages, this device is positioned for DC-powered networking gear.
• People who need flexible connectors: Included barrel adapters and USB options help when your router or accessories use different power plug standards.
• RV, car, or lab-style setups: The compact form factor and low-profile design fit mobile or bench setups where you do not want a traditional large UPS.
• Monitoring and alert systems: Reviewers mention power-loss alerts and small always-on systems as a good match.

What to check before you buy

1) Your devices’ total wattage

The unit’s total output max is 24W. Even if a single port appears to match your device’s voltage/current requirements, the combined draw across outputs can push the system beyond what it can reliably provide. If you plan to run a router plus another gadget (like a LAN switch or accessories), add up your power needs and stay comfortably under the 24W ceiling.

2) Voltage compatibility (5V, 9V, 12V)

This mini UPS supports DC outputs for 5V (USB-style use), 9V, and 12V, plus additional PoE voltage options for compatible CCTV style gear. Make sure your target devices run on one of these voltages, and use the correct barrel adapter or port.

3) Expected runtime during real outages

You should treat runtime as power-consumption dependent. The battery capacity is stated as 10400mAh (38Wh), and at an average of 10W it’s described as lasting around 3 hours. Charging a depleted battery is described as about 10 hours, so longer outages may outlast what the battery can cover.

Ports and connectivity, explained

This model is designed to reduce plug-compatibility friction. It supports multiple output types, including USB-A and USB-C PD fast charging, along with DC barrel connectors for several common sizes. The included adapter set covers multiple barrel dimensions, so it can be easier to power different routers, modems, and small DC devices without hunting for the right plug.

Pros and cons in real buyer terms

Pros you can count on

• Backup that feels practical: Multiple buyers describe it keeping modem/router-style gear alive through outages for hours.
• Simple usability: The combination of an LCD status screen and multi-port output is frequently cited as making the unit straightforward to use.
• Helpful protection features: Built-in protections for surge and overcharge/over-discharge are relevant for electronics you want to safeguard during unpredictable power.

Tradeoffs to keep in mind

• Limited headroom for multi-device setups: If your combined watt draw exceeds the 24W total cap, you may see unreliable behavior.
• Recharge time matters: If outages are frequent, the ~10-hour full recharge can limit how quickly the unit is ready again.
• Battery service is not quick: Battery replacement is possible but involves additional work because the battery is fixed in the compartment.

Verdict

The Yuuki Power mini UPS is a solid choice if you want a compact way to keep a router or small DC networking setup running during power cuts, especially when you benefit from the included barrel adapters and USB options. It becomes a poor fit if you want to power multiple devices at once without doing careful wattage math, since the 24W total output limit is a key constraint. For single-device router backup and monitoring-style gear, it looks like a practical, low-hassle solution.

Alternatives to consider

• A higher-output DC mini UPS: If you routinely run a router plus additional networking gear, look for a model with a higher total wattage rating so you have headroom.
• A larger-capacity battery backup: If your priority is longer runtime through extended outages, choose a unit with higher battery watt-hours rather than planning for only short interruptions.
• A dedicated power supply for PoE devices: If your priority is CCTV PoE switching, ensure the mini UPS’s supported PoE voltages match your specific equipment rather than assuming PoE compatibility automatically.
