Why Broadband Networks Need a Different Kind of Backup Power

Short power interruptions, voltage dips, and unstable grid conditions remain a persistent operational risk for telecom operators, Internet Service Providers (ISPs), fiber network operators, and system integrators. When a router, modem, or ONT loses power—even briefly—the device typically reboots, causing service interruption for the end user. Traditional AC UPS units are often oversized, costly to deploy at scale, and impractical for compact customer-premises equipment. This gap has created growing interest in a mini UPS for broadband service continuity without a traditional AC UPS, a category that Shanghai Mylion New Energy Co., Ltd., operating under the brand MYLION, has focused on for more than a decade.

Understanding the Mini UPS Category

A Mini UPS, in this context, refers to a compact DC backup power device designed to sit directly between the power adapter and the network equipment, maintaining voltage during brief outages without the footprint, cost, or AC-to-DC conversion overhead of a conventional UPS. Because devices such as routers, ONTs, ONUs, modems, gateways, and CPE equipment operate on regulated DC voltages—commonly 12V—matching the UPS output precisely to the device's voltage, working current, and peak/startup behavior becomes critical. Improper selection regarding voltage, current, peak load, or connector type is one of the most common causes of application failure in field deployments, a challenge MYLION has built its entire technical evaluation process around addressing.

MYLION's Strategic Positioning in DC Backup Power

Shanghai Mylion New Energy Co., Ltd. operates 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 positions itself not simply as a component supplier but as a B2B backup power partner and OEM/ODM project partner, meaning its role extends into requirement analysis, model matching, and documentation coordination rather than stopping at product shipment.

This positioning is grounded in over 13 years of experience in lithium battery technology and more than 10 years of experience specifically in Mini UPS development. The company's differentiated approach centers on evaluating backup power solutions based on real device voltage, working current, peak or startup current behavior, and the physical installation environment—followed by technical confirmation and connector or cable matching. This process is designed to reduce avoidable selection errors, which the company identifies as a leading cause of failed deployments in the field.

A Product Portfolio Built Around Real-World Voltage and Load Profiles

MYLION's catalog spans ten distinct products organized into functional series, each addressing a specific combination of voltage, current, and runtime requirements rather than offering a one-size-fits-all device.

The 12V Standard Series, including the MU26W, MU48W, and MU68W, is built for entry-level to mainstream broadband backup. The MU26W supports a 12V DC input up to 3.5A and delivers 2.5A continuous / 3A maximum output with 18.72Wh of battery energy, using DC5521 input and DC5525 output interfaces. The MU48W offers 29.6Wh of capacity with the same 2.5A/3A output profile, while the MU68W extends capacity to 44.4Wh with a maximum output of 36W (12V/3A) for professional ISP projects.

For deployments requiring longer backup windows without a change in output current, the 12V Long-Runtime Series—MU635W and MU635L—raises battery energy to 75.6Wh while maintaining the standard 2.5A continuous / 3A maximum output, targeting long-duration outages in residential or remote areas.

Higher-load equipment is addressed by the 12V High-Power Series. The MU65W supports a 12V DC input up to 6A and delivers 4A continuous / 5A maximum output (60W total) with 56.16Wh of battery energy, intended for high-performance WiFi equipment and storage-integrated gateways that exceed standard 2.5A thresholds. The 12V High-Power Long-Runtime Series, comprising the MU35W and MU35L, combines that same 60W output capability with 75.6Wh of battery energy for professional gateways requiring both high peak current and extended backup time.

Multi-device environments are served by the 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 and 37.44Wh battery capacity, suited to small office / home office setups powering a router and a USB accessory together. The MUJ435 extends this format to 50.4Wh while retaining the same 18W system limit and port configuration.

For installations managing two separate 12V devices from a single AC wall outlet, the AC-Input Dual Output Series ML1202AC uses LiFePO4 battery chemistry, accepts 100–240V AC input, and delivers two independent 12V DC outputs at 2A each (24W total system limit) with 25.6Wh of battery energy—commonly applied to combined ONT and router installations.

Looking Ahead: Development-Stage Directions

Beyond current production models, MYLION is evaluating two forward-looking directions for project-specific development. The MUC85 is a USB-C PD Mini UPS under development, designed for modern WiFi 6/7 devices requiring USB-C Power Delivery, with a 65W standard / 100W maximum PD input, two USB-C outputs (up to 20V/3.25A and up to 12V/2.5A), and 92.16Wh of battery energy. The MU248 addresses higher-voltage wireless CPE and radio bridge equipment through a 24V/48V telecom backup direction, using LiFePO4 chemistry, 48V/60V DC input, independent 24V (3A) and 48V (1A) outputs, a 100W total power limit, and 102.4Wh of battery energy. Both remain at the project evaluation stage rather than general availability.

Service Model: From Technical Matching to Mass Production

MYLION's service scope covers requirement analysis, model matching, sample testing support, connector and cable matching, private labeling, and documentation coordination—supporting both managed pilot evaluation and mass-production preparation for OEM/ODM customers. Compliance considerations are addressed at the model-specific level, with adherence to lithium battery transport documentation requirements, alongside UN38.3 and MSDS certifications applied per model.

Who This Approach Serves

This structured, voltage-matched approach to DC backup power is directed at telecom operators, Internet Service Providers, broadband network companies, fiber network operators, and system integrators, as well as distributors, brand owners, and OEM/ODM customers evaluating private-label or co-developed backup power lines. Platform compatibility spans routers, ONTs, ONUs, modems, gateways, CPE devices, and security or CCTV equipment, subject to electrical verification against the specific device's voltage and current profile.

For organizations evaluating a mini UPS for broadband service continuity without a traditional AC UPS, the practical takeaway is that selection should begin with the target device's actual electrical characteristics—not a generic wattage figure. Shanghai Mylion New Energy Co., Ltd., through its MYLION product line and technical matching process, structures its entire product and service approach around that principle, offering project-based evaluation and OEM/ODM support for customers seeking to reduce field failures tied to power backup mismatches.
