Understanding the Real Risk Behind Short Power Interruptions in Telecom CPE

Network equipment such as routers, modems, and ONTs frequently reboot or lose service during short power outages, voltage drops, or unstable grid conditions. For system integrators managing telecom, ISP, broadband, fiber networking, and security deployments, this is not a minor inconvenience—it directly affects service continuity for end customers. Improper UPS selection regarding voltage, current, peak load, or connectors can lead to application failure, meaning a backup power unit that looks adequate on paper may still fail to keep customer-premises equipment (CPE) online when it matters most.

This is the core challenge that Shanghai Mylion New Energy Co., Ltd., operating under the MYLION brand, was built to address. As a global B2B provider of Mini UPS products, DC backup power solutions, and project support for telecom, ISP, broadband, and security applications, the company positions itself as a backup power partner and OEM/ODM project partner rather than a generic component supplier.

Core Selection Criteria System Integrators Must Verify

Choosing backup power for telecom CPE is not a one-size-fits-all decision. It requires evaluating the actual device rather than assuming standard specifications will apply.

Voltage and Working Current Matching

The first step is confirming the real device voltage and working current, rather than relying on generic assumptions about "12V equipment." Many CPE devices operate within a 12V DC range, but their continuous current draw can vary significantly—from lightweight ONTs to high-performance WiFi routers and storage-integrated gateways. A UPS rated for 2.5A continuous output will not reliably support a device that regularly draws 4A.

Peak and Startup Current Behavior

Beyond steady-state operation, integrators must account for peak or startup current behavior. Devices often draw more current momentarily during boot-up or heavy processing loads than during normal operation. A backup power unit that only matches average current needs may still fail at the exact moment a device restarts after a power event.

Connector and Cable Compatibility

Even when voltage and current specifications align, connector and cable mismatches remain a common and avoidable cause of failure. Differences such as DC5521 versus DC5525 interfaces, or center-positive versus other polarity configurations, can render an otherwise correct UPS unusable without proper matching.

Battery Capacity and Runtime Requirements

Finally, installation environment and expected outage duration determine how much battery energy (measured in Wh) is appropriate. A short urban outage scenario has different requirements than long-duration power interruptions in residential or remote areas.

Matching Backup Power to Deployment Scenarios

Because CPE environments vary widely, MYLION structures its Mini UPS offerings around distinct deployment scenarios rather than a single universal product.

Standard 12V Deployments

For entry-level to mainstream broadband backup, the 12V Standard Series includes the MU26W, MU48W, and MU68W. The MU26W supports up to 3.5A DC input and delivers 2.5A continuous / 3A maximum 12V output with 18.72Wh of battery energy, using DC5521 input and DC5525 output connectors—suited for telecom, ISP, and home networking equipment. The MU48W offers 29.6Wh of energy with the same 2.5A continuous / 3A maximum output through a center-positive DC5525 output, targeting ISP and broadband network equipment. The MU68W extends capacity further to 44.4Wh with a maximum output of 36W (12V/3A), addressing professional ISP projects that need longer coverage.

Long-Runtime Requirements

For residential or remote installations facing extended outages, the 12V Long-Runtime Series—MU635W and MU635L—provides 75.6Wh of battery energy while maintaining the standard 2.5A continuous / 3A maximum 12V output, prioritizing prolonged service continuity for standard CPE devices.

High-Power CPE and Gateways

Higher-load equipment, such as high-performance WiFi systems and storage-integrated gateways, often exceeds standard 2.5A thresholds. The 12V High-Power Series MU65W supports up to 6A DC input and delivers 4A continuous / 5A maximum output (60W total), backed by 56.16Wh of battery energy. For scenarios requiring both high current and long backup time, the 12V High-Power Long-Runtime Series MU35W and MU35L combine the same 4A continuous / 5A maximum output with an increased 75.6Wh capacity, supporting professional gateways that need both performance and duration.

Multi-Device and Multi-Output Needs

Small office and home office (SOHO) setups frequently need to power more than one device type simultaneously. The 12V + USB Multi-Output Series addresses this with the MUJ46, which provides 1.5A continuous / 2A maximum 12V DC output alongside dual 5V/3A USB-A and USB-C outputs, within an 18W total system limit and 37.44Wh battery energy. The MUJ435 extends this concept with 50.4Wh of energy while maintaining the same 12V DC plus USB-A and USB-C ports and 18W system limit, offering longer runtime for multi-port environments.

AC-Input Dual Device Installations

For sites needing to manage two separate 12V devices—such as combined ONT and router installations—from a single wall outlet, the AC-Input Dual Output Series ML1202AC uses LiFePO4 battery chemistry with 100–240V AC input and two 12V DC output ports (2A each, 24W total system limit), supported by 25.6Wh of battery energy, simplifying deployment without requiring an external DC adapter.

Emerging USB-C PD and Higher-Voltage Directions

Looking toward evolving CPE requirements, MYLION’s development and project-evaluation directions include the MUC85, a USB-C PD Mini UPS under development supporting 65W standard / 100W max input, with USB-C outputs up to 20V/3.25A (65W) and 12V/2.5A (30W), and 92.16Wh of battery energy—designed for modern WiFi 6/7 devices requiring USB-C Power Delivery. Also under development is the MU248, targeting 24V/48V telecom backup for higher-voltage wireless CPE and radio bridge equipment, with 48V/60V DC input, independent 24V (3A) and 48V (1A) outputs, a 100W total system limit, LiFePO4 chemistry, and 102.4Wh of battery energy.

Why Technical Confirmation Matters Before Mass Deployment

Rather than shipping fixed configurations, MYLION emphasizes evaluation of solutions based on real device voltage, working current, peak/startup behavior, and installation environment, followed by technical confirmation and connector/cable matching to reduce selection errors. This service scope includes requirement analysis, model matching, sample testing support, connector/cable matching, private labeling, and documentation coordination—supporting managed pilot evaluation and mass-production preparation for OEM/ODM customers. Compatibility is verified across routers, ONTs, ONUs, modems, gateways, CPE devices, and security/CCTV equipment, subject to electrical verification rather than assumption.
