Selecting a mini UPS for telecom, ISP, and broadband customer-premises equipment is not a matter of picking a battery pack with the right shape. It requires a precise match between the electrical characteristics of the device being backed up and the electrical output of the backup unit. For system integrators managing large-scale rollouts of routers, ONTs, ONUs, modems, gateways, CPE devices, and security or CCTV equipment, an improper match can lead to application failure at the exact moment backup power is needed most.
Understanding the Core Challenge in Telecom Backup Power
Network equipment such as routers, modems, and ONTs often reboot or lose service during short power outages, voltage drops, or unstable grid conditions. This is a recognized pain point across telecom, ISP, and broadband deployments, particularly in regions where grid stability cannot be guaranteed. The consequence of an unplanned reboot is not merely inconvenience — it interrupts service continuity for subscribers and increases support costs for operators.
The underlying issue is frequently traced back to improper UPS selection regarding voltage, current, peak load, or connectors, which can lead to application failure even when a backup unit is technically present. A mini UPS that outputs the correct nominal voltage but insufficient continuous or peak current, for example, will not sustain a device through its startup or high-load moments.
What a Mini UPS Selection Guide Should Cover
A proper selection process for system integrators should evaluate several factors before any unit is deployed at scale.
Evaluating Voltage, Current, and Peak Load
Selection should be based on real device voltage, working current, peak or startup behavior, and the physical installation environment. Many CPE devices draw a higher current at startup than during steady-state operation, so a unit rated only for continuous load may fail to support the device reliably. This is why technical confirmation — checking a specific device's requirements against a specific UPS model's output specifications — is a necessary step rather than an optional one.
Connector and Cable Compatibility
Beyond voltage and current, connector and cable matching is a frequently overlooked variable. A mismatch in connector type, such as DC5521 versus DC5525, or polarity configuration, can prevent a functioning unit from powering a compatible device altogether. Confirming connector and cable compatibility as part of the selection process reduces avoidable field issues after deployment.
A Product Portfolio Built for Precision Selection
Shanghai Mylion New Energy Co., Ltd., operating under the brand MYLION and headquartered in Shanghai, China, positions itself 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 brings 13+ years of experience in lithium battery technology and 10+ years of experience in mini UPS development to its product line, which spans ten products organized into distinct series aligned with different device requirements.
The 12V Standard Series — including the MU26W, MU48W, and MU68W — addresses entry-level to mainstream broadband backup needs. The MU26W supports a 12V DC input up to 3.5A and a 12V DC output of 2.5A continuous or 3A maximum, with 18.72Wh of battery capacity and DC5521 input / DC5525 output interfaces. The MU48W offers 29.6Wh of energy with the same 2.5A continuous / 3A maximum output and a center-positive DC5525 output, while the MU68W extends capacity to 44.4Wh with a maximum output of 36W (12V/3A) for professional ISP projects.
The 12V Long-Runtime Series, represented by the MU635W and MU635L, retains the standard 2.5A continuous / 3A maximum output but increases battery energy to 75.6Wh, targeting long-duration power outages in residential or remote areas.
For higher-load equipment, the 12V High-Power Series MU65W supports a 12V DC input up to 6A and a 12V DC output of 4A continuous / 5A maximum (60W total), with 56.16Wh of battery energy — suited to high-performance WiFi equipment and storage-integrated gateways that exceed standard 2.5A thresholds. The 12V High-Power Long-Runtime Series MU35W and MU35L combine that same 60W output capability with 75.6Wh of battery capacity for professional gateways requiring both high peak current and extended backup time.
The 12V + USB Multi-Output Series addresses scenarios where a router and a USB accessory must be powered simultaneously. The MUJ46 provides a 12V DC output of 1.5A continuous / 2A maximum alongside dual 5V/3A USB-A and USB-C outputs, within an 18W maximum total output and 37.44Wh battery energy — suited to small office / home office setups. The MUJ435 extends battery energy to 50.4Wh while maintaining the same 12V DC + 5V USB-A + 5V USB-C port configuration and 18W system limit.
The AC-Input Dual Output Series ML1202AC uses LiFePO4 battery chemistry with a 100–240V AC input and two 12V DC output ports (2A each, 24W total system limit) with 25.6Wh of battery energy, allowing ONT and router combined installations to be powered from a single AC wall outlet without an external DC adapter.
Two additional directions, the MUC85 and MU248, remain in project evaluation. The MUC85 is designed around USB-C Power Delivery (65W standard / 100W max input) for modern WiFi 6/7 devices, with 92.16Wh of battery energy. The MU248 targets 24V/48V telecom backup applications using LiFePO4 chemistry, a 48V/60V DC input, independent 24V (3A) and 48V (1A) outputs, a 100W system limit, and 102.4Wh of battery energy for higher-voltage wireless CPE and radio bridge equipment.
Why Technical Confirmation Matters for System Integrators
Because electrical requirements vary significantly across routers, ONTs, ONUs, modems, gateways, CPE devices, and security or CCTV equipment, MYLION's approach centers on evaluation of solutions based on real device voltage, working current, peak/startup behavior, and installation environment, combined with technical confirmation and connector/cable matching to reduce selection errors. This process is intended to support more reliable DC backup deployment and reduce avoidable selection risks for professional project customers, rather than relying on a single generic product to fit all use cases.
Platform compatibility across routers, ONTs, ONUs, modems, gateways, CPE devices, and security/CCTV equipment is described as subject to electrical verification, reinforcing that model-by-model confirmation remains part of any responsible deployment process, even within an established product range.
Business Model and Support for Project-Based Deployments
MYLION operates as a B2B backup power partner and OEM/ODM project partner, working with telecom operators, Internet Service Providers, system integrators, distributors, brand owners, and OEM/ODM customers across telecom, ISP, broadband, fiber networking, and security industries. Services include requirement analysis, model matching, sample testing support, connector/cable matching, private labeling, and documentation coordination, with pricing structured around custom enterprise and project-based quotes rather than fixed retail pricing. After-sales support extends to technical evaluation, model matching, and project-specific documentation coordination, alongside managed pilot evaluation and mass-production preparation for larger rollouts. Applicable products carry model-specific UN38.3 and MSDS certifications relevant to lithium battery transport and compliance documentation.
Conclusion
For system integrators evaluating mini UPS options for telecom, ISP, broadband, or security deployments, the selection process benefits from a structured comparison of device voltage, current, peak load behavior, connector type, and installation environment against the specifications of each candidate unit. Shanghai Mylion New Energy Co., Ltd.'s portfolio — spanning standard, long-runtime, high-power, multi-output, AC-input, and emerging USB-C PD and 24V/48V directions — reflects an approach built around matching backup power characteristics to real-world device requirements, supported by project-based technical confirmation and OEM/ODM services for global telecom and broadband applications.
