Understanding the CPE Backup Power Challenge

Telecom operators, Internet Service Providers, and broadband network companies face a recurring operational issue: subscriber-side equipment such as routers, ONTs, modems, gateways, and CPE devices tend to reboot during short power interruptions, voltage drops, or unstable grid conditions. These repeated reboots translate into internet downtime, increased customer complaints, remote troubleshooting pressure, and higher field maintenance costs. For companies managing large fleets of customer premises equipment, this is not a minor inconvenience — it is a service continuity and cost-control problem that demands a purpose-built solution rather than a generic power backup product.

This is precisely the gap that Shanghai Mylion New Energy Co., Ltd., operating under the brand MYLION, has focused on addressing. Rather than positioning itself as a general UPS or consumer power bank supplier, MYLION operates as a specialized Mini DC UPS and telecom BBU solution provider built around the real deployment needs of broadband, fiber, ISP, and telecom infrastructure.

MYLION’s Engineering-Driven Approach

MYLION describes itself as an engineering-driven B2B manufacturer and OEM/ODM battery backup solution provider, drawing on over 13 years of experience in lithium battery packs, Mini UPS, and DC backup power development. Instead of selling a single generic UPS product, the company supports project-based model selection anchored in the actual operating conditions of the device being protected: real device voltage, working current, startup surge current, backup time target, installation environment, connector type, certification needs, labeling requirements, and mass production feasibility.

This matters specifically for CPE backup power because subscriber-side devices vary widely in their voltage and current demands. A standard low-current Mini UPS model that works for a basic router may be insufficient for a higher-performance gateway with greater startup surge or peak load. MYLION’s stated approach is to help customers evaluate actual working current, peak current, adapter rating, and load behavior before confirming a model — helping avoid the scenario where an under-rated backup unit causes a device to shut down, restart, or fail during customer testing.

Product Lineup Built for CPE Applications

MYLION’s Mini DC UPS and BBU catalog is structured around the range of CPE devices found in real deployments. The 12V Standard Mini DC UPS Series, which includes models MU68, MU26, and MU48, is designed as a compact 12V DC backup power solution for mainstream networking devices such as routers, ONTs, modems, gateways, and CPE devices used by ISPs, broadband operators, and system integrators. These units feature a built-in lithium battery pack with BMS protection against overcharge, over-discharge, overcurrent, and short circuit, packaged in a compact housing suitable for desktop, wall-mounted, or customer premises installation.

For higher-load scenarios, MYLION offers the High-Power 12V Telecom BBU Series, comprising models MU35 and MU65. This line is intended for advanced gateways, higher-power routers, WiFi gateways, and broadband CPE that require more current than standard Mini UPS models can support. It offers larger battery capacity options for longer backup time and is positioned for ISP gateway backup, broadband router backup, and operator-side trial projects where safety margin and real load evaluation are critical before model confirmation.

Space-constrained installations are addressed through the Inline FTTH Mini UPS Series, model MUJ46, an ultra-compact inline DC backup power solution designed to connect between the original power adapter and the device for simple DC-side backup. This addresses a specific pain point in FTTH and broadband installations where space near the ONT, router, or fiber terminal box is limited, and traditional desktop AC UPS products are too bulky or visible for customer-side deployment.

MYLION also extends its CPE-relevant range into newer device architectures with the USB-C PD Mini UPS Series (model MUC85) for devices using USB-C Power Delivery input, and the 24V / 48V DC Backup Power Series (model MU248) for selected telecom and wireless CPE devices that require higher DC voltage input than standard 12V equipment. For customers prioritizing battery longevity and thermal stability, the LiFePO4 Mini UPS Series (model ML1202AC) offers LiFePO4 battery chemistry with built-in BMS protection for long-term standby and repeated backup use.

Technical and Quality Discipline

Across this lineup, MYLION applies a consistent quality discipline: incoming material control, production process inspection, functional testing, aging or charge/discharge verification when required, and 100% outgoing inspection before shipment. The company also supports advanced customization for project-based applications, including housing, labeling, connectors, cables, battery capacity, charging parameters, and output configuration when technically feasible — a relevant capability for ISPs and distributors who need private-labeled CPE backup products rather than off-the-shelf hardware.

Compliance and Documentation for International Projects

For telecom and ISP customers operating across international markets, certification and transport documentation are practical concerns. MYLION states that its products can support international B2B project requirements including CE, FCC, RoHS, UN38.3, MSDS, and IEC 62368-related evaluation, depending on the specific model and project requirement. The company also emphasizes its understanding of lithium battery export requirements, supporting UN38.3, MSDS, shipping documentation, and labeling for international battery shipments. It is worth noting that certification availability may vary by product model and final configuration, and certification scope for customized projects should be confirmed based on the final approved version.

Market Validation Through Deployment Scenarios

MYLION reports that its Mini DC UPS and telecom BBU solutions — including MU68, MU26, MU48, MU35, and MU65 — have been supplied to international B2B customers for telecom, ISP, broadband, security, and networking backup power applications. These deployments span router backup, ONT backup, gateway backup, and broadband CPE backup use cases, with model selection based on real device voltage, working current, startup surge, connector type, required backup time, and deployment environment. The company’s FTTH-focused inline models, such as MUJ46, have similarly been positioned to help B2B customers build backup power solutions for residential broadband, small office networks, remote work setups, security systems, and regions with unstable power supply.

Conclusion

For telecom operators, ISPs, broadband network companies, and system integrators evaluating backup power for CPE devices, MYLION’s Mini DC UPS and BBU portfolio reflects a project-based, engineering-first approach rather than a one-size-fits-all product. With a model range spanning 12V standard and high-power series, inline FTTH designs, USB-C PD compatibility, 24V/48V options, and LiFePO4 chemistry, along with OEM/ODM support, quality inspection processes, and international compliance documentation, MYLION positions itself as a technical partner for B2B customers who need reliable, correctly matched, and well-documented backup power for subscriber-side network equipment.
