Backup time is a critical factor when evaluating Soluzioni Mini UPS for routers, ONTs, ONUs, and CPE devices. However, actual runtime is not determined by battery capacity alone. Load power, output efficiency, device requirements, and testing conditions all affect the final result.
For ISPs, telecom operators, network equipment manufacturers, and system integrators, accurate backup time testing helps verify whether a Mini UPS solution can maintain network connectivity during power interruptions.
MIO LEONE Soluzioni Mini UPS are designed for DC-powered applications such as routers, ONTs, ONUs, CPEs, gateways, CCTV systems, and IoT devices. A reliable evaluation should consider the complete power system, including the adapter, Mini UPS, battery, output conditions, and connected equipment.
Why Accurate Backup Time Testing Matters for Network Equipment
Unlike computers or monitors, routers and ONTs run 24/7 but draw relatively little power—typically between 5W and 15W combined. However, they are highly sensitive to voltage drops. A brownout or sudden blackout can cascade into service failures that require truck rolls to resolve.
Accurate backup time testing helps you:
- Determine if a Mini UPS can survive a typical local outage (5–10 minutes for flickers, 30–60 minutes for short outages, or 2–4 hours for extended events).
- Evitate di pagare troppo per batterie sovradimensionate.
- Plan for extended outages by pairing with generators or larger power stations.
Understanding the Power Consumption of Your Network Gear
Before you can test or calculate backup time, you need to understand exactly what you are powering. Not all network devices are created equal, and grouping them onto a single backup battery requires a clear understanding of their individual power draws.
Defining Your Network Devices
- Router:Routers manage local IP addresses, broadcast Wi-Fi, and route data. Modern high-speed routers (especially Wi-Fi 6/6E models) have robust processors that demand more power than older generation models.
- ONTs (Optical Network Terminals): Used in Fiber-to-the-Home (FTTH) setups. The ONT converts the optical light signal from the fiber optic cable into the electrical Ethernet signal your router can understand.
- CPE (Customer Premises Equipment):A catch-all term for any provider-owned network gear located at the customer’s site. This includes DSL modems, ONTs, standard gateways, and even small edge servers.

How to Read Device Power Ratings
To test backup time, you must locate the power sticker on the bottom or back of your device (or on its AC adapter). You are looking for three key metrics:
- Voltage:The electrical pressure required by the device. Most consumer and edge network routers operate on 12V or 9V DC.
- Amperage:The maximum electrical current the device is rated to pull.
- Wattage:The total power consumed.
Calculate the maximum theoretical wattage using this simple formula:
W = V × UN
For example, a standard 12V 1A router has a maximum theoretical power draw of 12 Watts.
However, this is the peak rating, not the average consumption. A router rated for 12W might only draw 5W during normal operation. This discrepancy is exactly why physical testing is necessary.
Step-by-Step Guide: How to Test Backup Time for Routers, ONTs, and CPE
Step 1: Set Up a Controlled Real-World Test Environment
To find your actual backup time, you must simulate a power outage.
- Ensure the Mini UPS is charged to 100%. (Check the LED capacity indicators).
- Connect your Router and/or ONT to the UPS using the correct DC output ports (e.g., matching the 12V output to a 12V router).
- The Mini UPS should operate normally with AC power connected, ensuring the devices boot up normally.
Step 2: Start the Power Interruption Test
- Disconnect AC/DC input and observe whether the connected device:
- Stays online without restart (acceptable)
- Riavvia brevemente (inaccettabile per molte applicazioni ISP)
- Mostra cali di tensione o instabilità durante il trasferimento (utilizzare un oscilloscopio se disponibile).
MIO LEONE Mini-UPS units feature zero-delay (0ms) switching, ensuring uninterrupted power to connected devices without any downtime during power outages.

Step 3: Simulate Normal Network Load
Unplug the UPS from the wall AC power. Note the exact time.
Crucial detail: Do not let the network sit idle. Network hardware consumes significantly more power when processing heavy data packets. To simulate an accurate business-day load:
- Stream a 4K video or run a continuous ping test on a connected computer.
- Initiate a large file download.
- Ensure multiple devices (phones, laptops, smart home hubs) remain connected to the Wi-Fi.
Step 4: Monitor, Record, and Evaluate
Allow the devices to run exclusively on the battery until the network drops. Note the exact time the router powers off.
Compare this physical runtime to your theoretical calculation. In many cases, the real-world time will actually exceed the theoretical time you calculated using the power supply’s sticker, because the router rarely draws its maximum rated amperage.
Key Factors That Impact the Actual Backup Time of Your UPS
If your physical test results differed wildly from your calculations, several variables are likely at play.
1. Battery Capacity
The fundamental determinant. Always compare in Wh, not mAh or Ah alone.
2. Device Load Power
Different devices consume dramatically different power—a basic ONT may draw 2W while an enterprise router draws 25W.
3. UPS Efficiency
DC Mini UPS units typically achieve 90–95% efficiency. This efficiency loss must be factored into calculations.
4. Depth of Discharge (DoD)
For lithium batteries, usable capacity is not 100% of rated capacity. Conservative DoD assumptions ensure reliable runtime predictions.
5. Temperature and Ventilation
Battery chemistry performs differently across temperature ranges. Poor ventilation can accelerate capacity degradation during discharge.
6. Battery Age
Runtime decreases as batteries age. Test with new units for baseline, but plan for degradation over the product lifecycle.
