How to Choose the Right MYLION Mini UPS for Router and ONT

Why Router and ONT Backup Power Selection Matters

Network equipment such as routers, modems, and ONTs often reboot or lose service during short power outages, voltage drops, or unstable grid conditions. For telecom operators, Internet Service Providers (ISPs), broadband network companies, fiber network operators, and system integrators, this is more than an inconvenience—it directly affects service continuity for subscribers. Improper UPS selection regarding voltage, current, peak load, or connectors can lead to application failure, making the choice of backup power equipment a technical decision, not just a purchasing one.

Shanghai Mylion New Energy Co., Ltd., operating under the brand MYLION, positions itself as a global B2B provider of Mini UPS products, DC backup power solutions, and project support for telecom, ISP, broadband, and security applications. With 13+ years of experience in Lithium Battery technology and 10+ years of experience in Mini UPS development, the company's approach centers on evaluating solutions based on real device voltage, working current, peak/startup behavior, and installation environment, followed by technical confirmation and connector/cable matching to reduce selection errors.

Understanding the Core Selection Criteria

Before choosing a Mini UPS for a router-and-ONT setup, several technical factors need to be confirmed:

• Voltage compatibility: Most routers and ONTs run on 12V DC systems, but some devices may require different input voltages.
• Working current vs. peak current: A device's continuous current draw may differ significantly from its startup or peak current, which affects whether a UPS can support it without failure.
• Connector type: Interfaces such as DC5521 and DC5525 must match the target device to avoid physical or electrical mismatches.
• Battery energy (Wh): This determines how long a device can run during an outage.

MYLION's model matching process reflects these criteria directly, offering evaluation and sample testing support so that project customers can confirm compatibility before mass deployment.

Matching Standard Router and ONT Loads with the 12V Standard Series

For entry-level to mainstream broadband backup needs, MYLION's 12V Standard Series covers a range of capacities:

• MU26W supports a 12V DC Input up to 3.5A and a 12V DC Output of 2.5A continuous / 3A maximum, with 18.72Wh of battery capacity and a DC5521 input / DC5525 output interface. It is positioned for compatible standard loads such as routers or ONTs experiencing short outage-related reboots.
• MU48W offers a mid-range capacity option with 29.6Wh energy and the same 2.5A continuous / 3A maximum 12V DC output, using a center-positive DC5525 output.
• MU68W extends runtime further with 44.4Wh energy and a maximum power output of 36W (12V/3A), suited for professional ISP projects that require more backup duration than entry-level models.

These three models illustrate how MYLION scales battery energy while keeping output current consistent, allowing customers to select based on required backup duration rather than changing electrical requirements.

Long-Runtime and High-Power Options for Demanding Setups

Some router and ONT installations, particularly in residential or remote areas facing longer outages, require more battery energy at the same standard current. The 12V Long-Runtime Series, represented by MU635W / MU635L, delivers 75.6Wh of battery energy while maintaining the same 2.5A continuous / 3A maximum 12V DC output as the standard series—prioritizing prolonged service continuity for standard CPE devices.

In contrast, high-load routers or gateways that exceed standard 2.5A thresholds require the 12V High-Power Series. The MU65W supports a 12V DC Input up to 6A and a 12V DC Output of 4A continuous / 5A maximum (60W total), backed by 56.16Wh of battery energy—intended for high-performance WiFi equipment and storage-integrated gateways.

For scenarios combining high current draw with extended runtime, the 12V High-Power Long-Runtime Series (MU35W / MU35L) combines the 4A continuous / 5A maximum output with 75.6Wh of battery capacity, addressing professional gateways that need both high peak current and long backup time.

Simplifying Combined Router-Plus-ONT Installations

A common scenario is powering both a router and an ONT from a single unit rather than two separate DC adapters. The AC-Input Dual Output Series, represented by the ML1202AC, is built specifically for this. It accepts 100–240V AC input and provides two 12V DC ports (2A each; 24W total system limit) using LiFePO4 battery chemistry with 25.6Wh of energy. This model is positioned for ONT + Router combined installations, offering simplified deployment without needing an external DC adapter for each device.

Multi-Output and Emerging Directions

Where a router or ONT setup also needs to support a USB-powered accessory, the 12V + USB Multi-Output Series becomes relevant. The MUJ46 provides a 12V DC Output of 1.5A continuous / 2A maximum, plus dual 5V/3A USB-A and USB-C outputs, within an 18W maximum total output and 37.44Wh battery energy—suited for small office/home office (SOHO) setups needing simultaneous backup for 12V and 5V devices. The MUJ435 extends this concept with 50.4Wh of battery energy while keeping the same 18W system limit and port configuration.

Looking ahead, MYLION also lists development/project-evaluation directions, including the MUC85, a USB-C PD Mini UPS designed for modern WiFi 6/7 devices requiring USB-C Power Delivery, and the MU248, targeting 24V/48V telecom backup for higher-voltage wireless CPE and radio bridge equipment. These remain under project evaluation rather than standard catalog items.

Why Technical Confirmation Remains Central

Across all series, MYLION's value proposition is not simply offering a range of wattages and battery sizes—it is supporting more reliable DC backup deployment and reducing avoidable selection risks for professional project customers. This is delivered through requirement analysis, model matching, sample testing support, connector/cable matching, private labeling, and documentation coordination, along with adherence to UN38.3 and MSDS compliance requirements on a model-specific basis.

For a router-and-ONT backup decision, this means the correct MYLION model depends on confirmed device voltage, working and peak current, connector type, and required runtime—criteria that MYLION's B2B project support and OEM/ODM services are structured to verify before deployment, whether for a single ISP installation or a broader system integrator project.
