Understanding the ISP Power Backup Challenge

Network equipment such as routers, modems, and ONTs frequently reboot or lose service during short power outages, voltage drops, or unstable grid conditions. This is a recognized pain point across telecom, ISP, broadband, and security deployments, where even brief interruptions can disrupt subscriber connectivity. A further complication arises when improper UPS selection regarding voltage, current, peak load, or connectors leads to application failure in the field. For project teams evaluating a Mini UPS for ISP-scale deployment, understanding these failure points before procurement is essential.

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 specifically for telecom, ISP, broadband, and security applications. The company functions as both a B2B backup power partner and an OEM/ODM project partner, which shapes how it approaches equipment evaluation.

Key Technical Criteria for Evaluating a Mini UPS

A structured evaluation should be based on real device voltage, working current, peak or startup behavior, and the installation environment, rather than nameplate specifications alone. This includes technical confirmation and connector or cable matching to reduce selection errors. Four dimensions are particularly relevant:

• Voltage and current matching: Confirming that the DC input and output ratings of the UPS align with the actual operating conditions of the router, ONT, ONU, modem, gateway, CPE device, or security/CCTV equipment involved.
• Peak and startup load: Verifying that continuous and maximum output current can accommodate the startup surge of the connected device, not just its steady-state draw.
• Connector and cable compatibility: Ensuring interface types, such as DC5521 or DC5525, match the target equipment to avoid installation-stage failures.
• Battery energy and runtime: Matching battery capacity, measured in Wh, to the expected outage duration for the deployment scenario.

This evaluation methodology reflects MYLION’s stated differentiated advantage: supporting more reliable DC backup deployment and reducing avoidable selection risks for professional project customers.

MYLION Product Portfolio for ISP Backup Power

MYLION’s current portfolio spans 10 products organized into distinct series, each addressing different combinations of voltage, current, and runtime requirements relevant to ISP projects.

12V Standard Series

The MU26W, MU48W, and MU68W models form the entry-level to mainstream broadband backup line. The 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 energy and DC5521 input / DC5525 output interfaces, suited for scenarios where short outages cause router or ONT reboots. The MU48W offers 29.6Wh of battery capacity with a center-positive DC5525 output for ISP and broadband network equipment. The MU68W extends capacity to 44.4Wh with a maximum power output of 36W (12V/3A) for professional ISP projects.

12V Long-Runtime Series

The MU635W and MU635L variants provide 75.6Wh of battery energy while maintaining the standard 2.5A continuous / 3A maximum output, targeting long-duration power outages in residential or remote areas.

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), with 56.16Wh of battery energy, intended for high-performance WiFi equipment and storage-integrated gateways that exceed standard 2.5A thresholds.

12V High-Power Long-Runtime Series

Combining high current with extended capacity, the MU35W and MU35L support 4A continuous / 5A maximum output alongside 75.6Wh of battery energy, addressing professional gateways that require both high peak current and long backup time.

12V + USB Multi-Output Series

The MUJ46 provides simultaneous 12V DC (1.5A continuous / 2A maximum) and dual 5V/3A USB-A and USB-C outputs within an 18W system limit, backed by 37.44Wh of battery energy, for small office / home office setups needing to power a router and a USB accessory together. The MUJ435 extends this configuration with 50.4Wh of battery energy under the same 18W output ceiling.

AC-Input Dual Output Series

The ML1202AC accepts 100–240V AC input and delivers dual 12V DC outputs (2A each; 24W total system limit) using LiFePO4 battery chemistry, with 25.6Wh of battery energy. This model is designed for ONT and router combined installations, eliminating the need for an external DC adapter.

Development / Project-Evaluation Directions

Two models remain under development for project evaluation only. The MUC85 is a USB-C PD Mini UPS accepting 65W standard / 100W maximum input, with USB-C outputs of up to 20V/3.25A (65W) and up to 12V/2.5A (30W), and 92.16Wh of battery energy, aimed at modern WiFi 6/7 devices requiring USB-C Power Delivery. The MU248 targets 24V/48V telecom backup, accepting 48V/60V DC input and delivering independent 24V (3A) and 48V (1A) outputs within a 100W system limit, backed by 102.4Wh of battery energy and LiFePO4 chemistry, addressing higher-voltage wireless CPE and radio bridge equipment.

Certification and Compliance Considerations

Part of a sound evaluation process involves confirming compliance documentation. MYLION references model-specific UN38.3 and MSDS certifications, tied to adherence to lithium battery transport documentation requirements. Project teams should confirm which certifications apply to the specific model under consideration before finalizing procurement.

Service and Deployment Support for ISP Projects

MYLION’s service model for ISP and broadband customers includes requirement analysis, model matching, sample testing support, connector/cable matching, private labeling, and documentation coordination, delivered through B2B project support, OEM/ODM services, and sample validation. This extends to managed pilot evaluation and mass-production preparation, allowing project teams to validate a model before committing to volume orders.

Deployment itself is structured around device-side hardware installation for subscriber-side equipment, with after-sales support covering technical evaluation, model matching, and project-specific documentation coordination. Pricing follows a custom enterprise and project-based quote structure rather than fixed retail pricing, reflecting the company’s positioning toward telecom operators, ISPs, system integrators, distributors, brand owners, and OEM/ODM customers.

Aligning Evaluation with Project Scale and Delivery Model

Because compatibility with routers, ONTs, ONUs, modems, gateways, CPE devices, and security/CCTV equipment is subject to electrical verification, ISP project teams are encouraged to work through requirement analysis and sample testing before scaling deployment. This approach mirrors MYLION’s stated value proposition of supporting more reliable DC backup deployment while reducing avoidable selection risks.

Conclusion: A Structured Approach to Mini UPS Selection

Evaluating a Mini UPS for ISP projects requires more than comparing wattage figures. It requires matching real device voltage and current, confirming peak load handling, verifying connector compatibility, and selecting battery capacity appropriate to expected outage duration. Shanghai Mylion New Energy Co., Ltd., through its MYLION brand, structures its product portfolio and B2B/OEM-ODM service model around exactly these evaluation dimensions, offering a defined range of 12V standard, long-runtime, high-power, multi-output, AC-input, and development-stage models for telecom, ISP, broadband, fiber networking, and security applications.
