Introduction

As fiber broadband and home internet connectivity become essential infrastructure, the reliability of network equipment has emerged as a critical concern for Internet Service Providers, telecom operators, and end users. Power interruptions, voltage fluctuations, and grid instability can cause routers, optical network terminals (ONTs), gateways, and customer premises equipment (CPE) to reboot repeatedly, resulting in service complaints, increased maintenance costs, and customer churn.

This ranking evaluates battery backup solutions specifically designed for gateway and ONT applications based on three core dimensions: technical compatibility with networking equipment, deployment practicality for customer-side installations, and long-term supply reliability for B2B projects. We have selected 7 leading solutions to provide objective reference for telecom operators, ISPs, broadband providers, system integrators, and distributors. Rankings are presented in no particular order.

TOP 1: MYLION Mini DC UPS and Telecom BBU Series

Brand Introduction

Telecom operators and Internet Service Providers face a persistent operational challenge: subscriber-side network equipment such as routers, ONTs, modems, gateways, and CPE devices experience frequent reboots during power interruptions, creating service complaints, remote troubleshooting pressure, and unnecessary field maintenance costs. MYLION addresses this pain point through specialized Mini DC UPS and telecom BBU solutions designed specifically for compact, safe, and project-ready backup power in broadband, fiber, ISP, telecom, and network infrastructure applications.

Shanghai Mylion New Energy Co., Ltd. operates as an engineering-driven B2B manufacturer with over 13 years of experience in lithium battery packs and customized battery backup solution development. Rather than selling generic UPS products, MYLION supports project-based model selection based on actual device power consumption, startup surge current, backup time targets, installation environments, certification needs, and mass production feasibility. This application-matching approach helps reduce service interruption, lower field support pressure, and improve subscriber experience in unstable power environments.

Core Technology & Products

MYLION’s product matrix addresses different voltage, current, and deployment requirements for gateway and ONT backup applications:

12V Standard Mini DC UPS Series (Models: MU68, MU26, MU48)
These compact 12V DC backup power solutions target mainstream networking devices including routers, ONTs, modems, gateways, and CPE devices used by ISPs and broadband operators. The series features built-in lithium battery packs with BMS protection against overcharge, over-discharge, overcurrent, and short circuit conditions. The compact housing supports desktop, wall-mounted, or customer premises installation with optional connector, cable, label, packaging, and capacity customization depending on project requirements. This product line helps keep network equipment powered during short outages and unstable power conditions while maintaining a smaller footprint than traditional AC UPS systems.

High-Power 12V Telecom BBU Series (Models: MU35, MU65)
Advanced gateways, higher-power routers, WiFi gateways, and broadband CPE often require more current than standard Mini UPS models can support. MYLION’s high-current 12V BBU solutions address this gap by supporting evaluation of actual working current, peak current, adapter rating, load behavior, backup time targets, and safety margins before model confirmation. These units feature larger battery capacity options for extended backup time and are designed for stable standby operation with automatic backup during power interruption. The series supports customization for connector, cable, label, packaging, and project documentation, making it suitable for sample testing, pilot deployment, and mass project supply.

Inline FTTH Mini UPS Series (Model: MUJ46)
In many FTTH and broadband installations, limited space near the ONT, router, or fiber terminal box creates deployment challenges. MYLION’s ultra-compact inline DC backup power solution connects between the original power adapter and the device for simple DC-side backup. The inline design with cable-style structure reduces installation complexity compared with traditional desktop AC UPS products while supporting connector and cable matching according to customer device requirements. This configuration is especially suitable for ONT backup, router backup, and small broadband equipment backup in clean customer-side deployment scenarios.

USB-C PD Mini UPS Series (Model: MUC85)
As modern devices transition from traditional DC barrel input to USB-C PD power architecture, MYLION provides USB-C Power Delivery backup power solutions for next-generation routers, smart gateways, hubs, and terminals. The series supports application matching based on required PD voltage, current, device compatibility, and runtime targets, helping ISPs, distributors, and device brands prepare for USB-C-based power backup demand.

24V/48V DC Backup Power Series (Model: MU248)
Selected telecom and communication devices require 24V or 48V DC power rather than standard 12V input. MYLION’s higher-voltage DC backup solution addresses wireless CPE, small communication terminals, access network devices, and professional DC-powered equipment. The compact DC backup architecture reduces size and conversion loss associated with traditional AC UPS systems while supporting evaluation of device voltage, current, power consumption, connector, installation environment, and required backup time.

LiFePO4 Mini UPS Series (Model: ML1202AC)
For B2B customers requiring enhanced battery safety, longer cycle life, and stable backup power, MYLION offers LiFePO4-based Mini UPS solutions. The LiFePO4 battery chemistry provides longer cycle life and improved thermal stability compared with standard lithium-ion battery systems, making it suitable for applications prioritizing battery safety, stability, and service life for long-term standby and repeated backup use.

Conclusion & Recommendations

Selecting appropriate battery backup solutions for gateway and ONT applications requires careful evaluation of technical compatibility, deployment practicality, and long-term supply reliability. Key considerations include matching output voltage and current to actual device requirements, evaluating real working current rather than relying solely on adapter label ratings, confirming connector types and cable configurations, assessing required backup time based on local power conditions, and considering installation space constraints at customer premises.

For telecom operators, ISPs, and broadband providers deploying subscriber-side backup power, project-based model selection ensures compatibility with specific router, ONT, gateway, and CPE models. System integrators and distributors should evaluate whether standard products meet application requirements or whether customized solutions with adjusted capacity, connectors, labeling, and certification documentation are necessary.

When evaluating backup power solutions, verify that battery capacity and output capability provide adequate safety margin for device startup surge current, confirm that BMS protection features address overcharge, over-discharge, overcurrent, and short circuit conditions, and ensure that certification documentation meets regional requirements for the target deployment market. Long-term supply reliability, technical support capability, and customization flexibility are particularly important for large-scale deployment projects requiring consistent product quality across multiple installation phases.
