A broadband installation may need backup power for more than one type of device. An ONT, router or modem may use a 12V DC supply, while an auxiliary terminal or mobile device requires 5V USB power.
For ISPs, telecom operators and system integrators, this creates a practical challenge: how to support the essential network equipment and selected accessories within a clearly defined backup arrangement.
The MYLION MUJ46 Mini UPS combines 12V DC, USB-A 5V and USB-C 5V output options in a compact unit. It provides a solution direction for compatible broadband equipment and mixed DC-and-USB installations, with the final configuration determined by device requirements and total operating demand.
Why Multi-Output Matters for Broadband Installations
Multi-output backup solution helps project teams consider the main network device and auxiliary USB equipment within one power plan. This makes it easier to identify which functions need to remain available during an outage.
MUJ46’s 12V DC, USB-A 5V and USB-C 5V connections provide different output options for compatible equipment, helping buyers define the intended device configuration.
A clear equipment, cable and load list also gives installers a practical reference. It shows which device connects to each output, which cable is required and what combined demand must be considered, helping teams understand the project requirements before installation.
What Does MUJ46 Multi-Output Backup Provide?
The MYLION MUJ46 Mini UPS provides three output connections for different device requirements.

USB-C output | 5V, 3A maximum |
Output power | 18W |
Input | 12V DC, 3A maximum |
Battery | 37.44Wh lithium-ion |
Dimensions | 145 × 90 × 26mm |
Housing | Fire-resistant ABS |
Three Output Types for Different Device Requirements
12V DC: The Main Network Device
The DC output provides a connection option for a compatible ONT, ONU, low-power CPE, router or modem.
Device selection should account for input voltage, operating demand, connector dimensions and polarity. A matching nominal voltage is only one part of the requirement.
USB-A: A Selected 5V Accessory
The USB-A output can serve compatible small terminals, accessories or mobile devices that accept the available 5V supply.
For a business installation, the accessory should have a defined purpose during an outage. Its power demand belongs in the same backup plan as the main network device.
USB-C: A Compatible 5V Device
The USB-C connection offers a second USB connector format for suitable equipment, such as a compatible phone or small terminal.
For example, a site contact may need a phone available for outage reporting while the local network equipment operates on backup. The phone represents an additional load that should be included in the power plan.
MUJ46 Application Scenarios for Broadband and Network Backup
The following applications describe solution directions rather than verified compatibility with specific device models.
1.ONT and ONU Backup
MUJ46 can be considered for a compatible 12V ONT or ONU at the subscriber premises. The installation plan should also account for any separate router needed to maintain the intended connection.
2.Low-Power CPE Backup
For low-power CPE accepting a compatible 12V DC supply, MUJ46 offers a compact backup option. CPE requiring PoE, another voltage or higher power needs a separately approved solution.
3.Router and Auxiliary USB Device Backup
A compatible router can use the DC connection while a selected 5V accessory uses USB-A or USB-C. This arrangement suits projects where a supporting terminal also needs power during an interruption.
4.Modem and Mobile Device Backup
A compatible modem and a mobile device can support fixed broadband and staff communication respectively. Mobile charging demand should be included in the total load, with network operation given the appropriate priority.
5.Broadband Equipment Requiring 12V and 5V USB
For installations combining DC-powered broadband equipment and USB accessories, MUJ46 provides a mixed-output solution direction. Define the complete device group and confirm the permitted output combination before deployment.
Planning Power Across DC and USB Outputs
Every active device contributes to the power required from the backup unit. Small USB loads can make a meaningful difference when added to the main broadband equipment.
The following example uses hypothetical device loads to illustrate the calculation. It is not a MUJ46 test result or an approved equipment combination.
Illustrative Device | Assumed Working Demand | Calculated Power |
Main DC network device | 12V × 0.75A | 9W |
USB-A accessory | 5V × 0.4A | 2W |
USB-C accessory | 5V × 0.6A | 3W |
Combined demand |
| 14W |
Power in watts = Voltage × Current
In this example, the USB devices add 5W to the main device’s 9W demand. Planning around the network device alone would overlook more than one-third of the combined operating load.
Although 14W is below the published 18W output figure, that comparison alone does not establish compatibility. Individual output limits, startup demand, cable requirements and continuous operating conditions still apply.
Explore Other MYLION Backup Solutions
Different broadband projects require different backup configurations. Alongside MUJ46, MYLION MUJ435 is another multi-output option to consider for projects involving network equipment and USB-powered accessories.
Buyers comparing the two models should define the main device, auxiliary USB loads, target backup duration and installation requirements. Model selection should follow the current specifications and the complete equipment configuration.
