Why Network Equipment Needs Dedicated DC Backup Power

Modern broadband infrastructure — routers, ONTs, modems, gateways, and CPE devices — runs on low-voltage DC power. Yet most backup power strategies still default to bulky AC UPS systems that convert power multiple times before reaching sensitive network hardware. The mismatch is real: AC-to-DC losses, oversized footprints, and connector incompatibilities frequently result in failed deployments and avoidable service disruptions.

The underlying problem is not the power outage itself. It is the reboot cycle. Even a short voltage drop or a brief grid interruption can force a router or ONT to restart, dropping subscriber sessions and triggering support tickets. For telecom operators, ISPs, and fiber network operators managing thousands of customer-premises installations, these micro-events accumulate into measurable service degradation.

MYLION, the brand of Shanghai Mylion New Energy Co., Ltd., was built as a direct response to this pain point. With more than 13 years of experience in lithium battery technology and more than 10 years focused specifically on Mini UPS development, the company has structured its entire product architecture around DC backup for network subscriber-side equipment.

What Makes Mini DC UPS Different From Standard AC UPS

A Mini DC UPS is engineered to accept DC input directly from a wall adapter and deliver regulated DC output to a specific class of device — most commonly 12V network equipment. This bypass of AC-DC conversion stages matters for two reasons: efficiency and precision.

From an efficiency standpoint, eliminating the AC-DC conversion stage on the output side reduces energy waste. From a precision standpoint, the output voltage, current rating, and connector type can be matched exactly to the target device — whether that is a dual-band router drawing less than 2.5A or a high-performance gateway requiring up to 4A or 5A peak current.

MYLION addresses this precision problem explicitly. The company’s deployment approach involves evaluating each project based on the actual working voltage, working current, and peak or startup behavior of the connected device before confirming a model. Connector and cable matching is treated as part of the selection process, not an afterthought — a discipline that directly reduces the risk of selection errors on live deployments.

MYLION’s Product Portfolio: Matching Hardware to Application

MYLION’s current Mini UPS lineup covers a structured range of 12V DC applications with meaningful differentiation across battery capacity, output current, and form factor.

Standard Output: Entry to Mainstream

The MU26W, MU48W, and MU68W form the standard 12V series. The MU26W provides 18.72Wh of energy with 2.5A continuous output through a DC5521 input and DC5525 output interface — designed for entry-level loads and ISP home networking installations. The MU48W steps capacity to 29.6Wh while maintaining the same 2.5A continuous output rating with a center-positive DC5525 output. The MU68W extends runtime further with 44.4Wh and a maximum 36W output (12V/3A), making it well-suited for professional ISP project deployments.

Extended Runtime for Prolonged Outages

The MU635W and MU635L are engineered specifically for scenarios where outages extend beyond standard durations. Both carry 75.6Wh battery energy with 2.5A continuous output — addressing long-duration power interruptions in residential or remote-area installations where entry-level capacity falls short.

High-Power Configurations for Performance-Heavy Equipment

Where the connected device exceeds standard 2.5A thresholds — common in high-performance WiFi equipment and storage-integrated gateways — the MU65W provides 4A continuous output, 5A maximum, and 56.16Wh energy. Its 12V DC input supports up to 6A, with a 60W total output capacity. For installations that must combine high output current with extended backup duration, the MU35W and MU35L deliver the same 4A continuous, 5A maximum output alongside 75.6Wh capacity — designed for professional gateways requiring both high peak current tolerance and long backup time.

Multi-Output for Combined Device Installations

The MUJ46 and MUJ435 address environments where a 12V network device and USB-powered accessories require simultaneous backup. The MUJ46 provides 12V DC at 1.5A continuous alongside dual 5V/3A USB outputs — one USB-A and one USB-C — within an 18W total system limit, backed by 37.44Wh energy. The MUJ435 extends battery energy to 50.4Wh under the same port architecture, providing longer runtime for small office and home office setups.

For installations drawing from a single AC wall outlet, the ML1202AC offers dual 12V DC outputs (2A each, 24W total system limit) with LiFePO4 chemistry and 100–240V AC input. This model supports combined ONT and router installations without requiring a separate external DC adapter — simplifying deployment in residential broadband environments.

Emerging Directions for Next-Generation Network Hardware

Two development directions reflect MYLION’s alignment with the evolving requirements of modern network hardware.

The MUC85 targets WiFi 6/7 devices and other modern equipment requiring USB-C Power Delivery input. Its architecture supports USB-C PD input up to 100W, with USB-C Output 1 providing up to 20V/3.25A (65W) and USB-C Output 2 up to 12V/2.5A (30W), alongside 92.16Wh battery energy. This model is currently at the project evaluation stage.

The MU248 addresses higher-voltage wireless CPE and radio bridge equipment through independent 24V (3A) and 48V (1A) outputs, LiFePO4 chemistry, 48V/60V DC input, and 102.4Wh battery energy at a 100W total system limit. Both directions indicate that the product roadmap is being shaped by the actual voltage and interface requirements of next-generation subscriber-side equipment.

B2B Project Support as a Core Service Competency

MYLION positions itself explicitly as a B2B backup power partner rather than a retail supplier. The engagement model reflects this orientation: OEM and ODM project support, sample validation, connector and cable matching, private labeling, and documentation coordination are all included in the project partnership scope. Certifications including UN38.3 and MSDS are maintained on a model-specific basis to meet lithium battery transport requirements for international project logistics.

The company serves telecom operators, ISPs, fiber network operators, system integrators, distributors, and brand owners — all parties involved in subscriber-side equipment deployment at scale. Pricing is handled through custom enterprise and project-based quotes, and delivery capability spans from pilot evaluation through mass-production preparation.

Key Technical Considerations for Deployment Success

Selection success in Mini DC UPS deployments depends on variables that extend beyond battery capacity alone.

Output current adequacy — The connected device’s peak or startup current must not exceed the UPS output maximum. High-performance gateways may require 4A–5A peak tolerance, which only the MU65W and MU35W/MU35L series address within the current production lineup.

Connector and cable compatibility — Interface mismatch is among the most common causes of failed broadband UPS deployments. MYLION’s project confirmation process specifically evaluates this variable before sample shipment.

Battery energy and runtime — Target backup duration, combined with the device’s actual power draw, determines the required watt-hour capacity. The current production lineup spans from 18.72Wh to 75.6Wh.

Installation environment — AC-input environments benefit from the ML1202AC’s integrated adapter architecture. High-wattage DC-input environments align with the MU65W or MU35W/MU35L configurations.

For ISPs and system integrators evaluating Mini DC UPS deployments at scale, MYLION’s technical confirmation process — covering real device voltage, current profiles, peak behavior, and connector specifications — is designed to reduce selection risk before pilot validation begins.
