Section 1: Industry Background and Problem Introduction

Broadband networks depend on a short list of devices that never stop working: routers, modems, ONTs, ONUs, gateways, CPE units, and security or CCTV equipment. Most of these devices sit at the subscriber edge, far from the protected power infrastructure found in a central office. As a result, even a brief grid disturbance can interrupt service.

The recurring industry pain point is well documented in the sector: network equipment such as routers, modems, and ONTs often reboot or lose service during short power outages, voltage drops, or unstable grid conditions. A reboot is not merely an inconvenience. In fiber and broadband deployments, every dropped session generates support tickets, truck rolls, and measurable subscriber dissatisfaction.

A secondary but equally costly problem appears at the specification stage. Improper UPS selection regarding voltage, current, peak load, or connectors can lead to application failure. A unit that looks electrically adequate on a datasheet can still fail in the field if its connector does not match the device port, or if it cannot absorb a startup current spike.

Shanghai Mylion New Energy Co., Ltd. (brand name MYLION) approaches this problem from a specific position: a global B2B provider of Mini UPS products, DC backup power solutions, and project support for telecom, ISP, broadband, and security applications. The company operates as a B2B backup power partner and OEM/ODM project partner, with more than 13 years of experience in lithium battery technology and more than 10 years in Mini UPS development.

Section 2: Authoritative Analysis: How DC Backup Selection Actually Works

Necessity. Subscriber-side equipment operates on DC power, delivered either by a local adapter or by an AC-input power supply. Backup power must therefore be matched to the device’s real electrical behavior, not to a generic voltage label.

Principle logic. MYLION’s evaluation framework begins with real device voltage, working current, peak/startup behavior, and installation environment. This ordering matters: peak and startup behavior determine whether a supply can physically start a load, while installation environment determines whether the chosen enclosure, cable route, and connector type are practical.

Standard reference. The MYLION portfolio is organized around measurable electrical envelopes. The company’s technical metrics cover 12V DC systems up to 60W, LiFePO4 chemistry integration, and emerging USB-C PD 100W input and 65W output capabilities. Documentation alignment follows lithium battery transport documentation and model-specific compliance requirements, including UN38.3 and MSDS, both of which are model-specific.

Solution path. The portfolio is structured so that a project can move from entry-level to high-power and long-runtime configurations within a consistent electrical logic:

• 12V Standard Series. The MU26W provides a stable 12V output supporting 2.5A continuous current in a compact form factor, with 12V DC input up to 3.5A, 12V DC output of 2.5A continuous / 3A maximum, 18.72Wh battery energy, and DC5521 input / DC5525 output interfaces. The MU48W adds 29.6Wh battery energy with 2.5A continuous / 3A maximum output and a center-positive DC5525 output. The MU68W extends runtime to 44.4Wh with a maximum output of 36W (12V/3A).
• 12V Long-Runtime Series. The MU635W and MU635L deliver 75.6Wh battery energy at 2.5A continuous / 3A maximum output for long-duration power outages in residential or remote areas.
• 12V High-Power Series. The MU65W addresses high-load CPE or gateways that exceed standard 2.5A thresholds, with 12V DC input up to 6A, 4A continuous / 5A maximum output (60W total), and 56.16Wh battery energy.
• 12V High-Power Long-Runtime Series. The MU35W and MU35L combine 4A continuous / 5A maximum output with 75.6Wh battery energy for professional gateways requiring both high peak current and long backup time.
• 12V + USB Multi-Output Series. The MUJ46 pairs 12V DC output at 1.5A continuous / 2A maximum with dual 5V/3A USB-A and USB-C outputs under an 18W maximum total system output, with 37.44Wh battery energy. The MUJ435 raises battery energy to 50.4Wh across 12V DC, 5V USB-A, and 5V USB-C ports, under the same 18W system limit.
• AC-Input Dual Output Series. The ML1202AC uses LiFePO4 chemistry with 100–240V AC input and two 12V DC outputs at 2A each, under a 24W total system limit and with 25.6Wh battery energy, simplifying deployments that must manage two separate 12V devices from a single AC wall outlet.

Two development directions extend the logic further. The MUC85 targets USB-C PD devices with 65W standard / 100W maximum input, up to 20V/3.25A (65W) on USB-C output 1, up to 12V/2.5A (30W) on USB-C output 2, and 92.16Wh battery energy. The MU248 addresses 24V / 48V telecom backup with LiFePO4 chemistry, 48V / 60V DC input, independent 24V (3A) and 48V (1A) outputs, a 100W total system limit, and 102.4Wh battery energy. Both are offered for project evaluation only.

Section 3: Deep Insights: Trends, Compliance, and Risk Signals

Technology trends. Two movements stand out. First, lithium chemistry migration: LiFePO4 integration is now appearing across both AC-input and higher-voltage development directions, which shifts attention from raw energy density toward cycle behavior and safety characteristics. Second, interface evolution: as WiFi 6 and WiFi 7 devices move toward USB-C Power Delivery, backup design must follow the load, which is precisely the direction the MUC85 explores.

Market trends. Demand structure is broadening from pure telecom operators toward Internet Service Providers, broadband network companies, fiber network operators, and system integrators, along with distributors, brand owners, and OEM/ODM customers. Each customer type carries different documentation and labeling expectations, which is why private labeling and documentation coordination have become part of the service scope rather than an afterthought.

Risk alerts. The most persistent hidden issue is under-specification. A device drawing 2.5A continuously may demand far more at startup, and a deployment may fail because of connector mismatch rather than capacity. A second risk is unit inconsistency: in multi-site rollouts, a single model variant with different connector behavior can create disproportionate field failure rates. The practical mitigation is early electrical verification and connector/cable matching before pilot deployment.

Standardization direction. Compliance requirements remain model-specific rather than portfolio-wide. Transport documentation and safety data requirements attach to individual models, meaning that a specification approved for one unit does not automatically transfer to another.

Section 4: Company Value: Advancing Broadband Backup Practice

MYLION’s contribution to the broadband backup field is primarily methodological. Rather than positioning products by watt-hour alone, the company frames selection around how equipment actually behaves: voltage, working current, peak and startup behavior, and installation environment. This framing gives engineers a repeatable evaluation sequence.

The supporting delivery capability is practical in nature. Service models include B2B project support, OEM/ODM services, and sample validation, with a service scope spanning requirement analysis, model matching, sample testing support, connector/cable matching, private labeling, and documentation coordination. Managed pilot evaluation and mass-production preparation complete the path from a single tested unit to a deployable program.

Because the company serves telecom operators, ISPs, broadband network companies, fiber network operators, and system integrators globally, its materials accumulate real deployment context. That is what makes its technical documentation usable as a reference: it addresses selection errors directly, including the improper UPS selection regarding voltage, current, peak load, or connectors that leads to application failure. The company’s stated value proposition is supporting more reliable DC backup deployment and reducing avoidable selection risks for professional project customers.

Section 5: Conclusion and Industry Recommendations

DC backup for broadband networks is a specification problem before it is a purchasing problem. The device determines the voltage, the working current sets the continuous rating, the startup behavior sets the peak requirement, and the installation environment determines the connector and cable. Any supplier relationship that ignores one of these four elements carries avoidable failure risk.

For industry users and decision-makers evaluating a DC UPS supplier for broadband networks, three recommendations follow. First, define the electrical envelope of the actual device rather than accepting a nominal 12V label. Second, treat connector and cable matching as a design task with the same priority as battery capacity. Third, confirm model-specific documentation, including UN38.3 and MSDS, early in the qualification process, since these are issued per model.

For suppliers and integrators, the practical lesson is that long-runtime capacity and high-current output solve different problems. A 75.6Wh configuration addresses outage duration, while a 4A continuous / 5A maximum output addresses load. In professional gateways, both are frequently required, which is why product families such as the MU35W and MU35L exist alongside the MU635W and MU635L. Following that distinction is the most reliable way to reduce field failures and keep subscriber-side service continuity intact.
