Understanding the Need for Mini UPS Backup Power in Networking
Network equipment such as routers, modems, and ONTs often reboot or lose service during short power outages, voltage drops, or unstable grid conditions. For telecom operators, Internet Service Providers (ISPs), broadband network companies, fiber network operators, and system integrators, this type of service interruption is a recurring operational concern. Improper UPS selection regarding voltage, current, peak load, or connectors can lead to application failure, which makes the selection process itself a critical step rather than an afterthought.
Shanghai Mylion New Energy Co., Ltd., operating under the brand MYLION, is 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 B2B backup power partner and OEM/ODM project partner, with 13+ years of experience in lithium battery technology and 10+ years of experience in Mini UPS development specifically.
Key Selection Criteria for Choosing a Mini UPS for Routers
Selecting the right Mini UPS for a router or similar network device requires evaluating several technical factors together, rather than focusing on a single specification.
Voltage and Current Matching
The first requirement is confirming that the UPS output voltage matches the router's rated input voltage, and that the continuous output current meets or exceeds the device's working current. MYLION evaluates solutions based on real device voltage, working current, peak/startup behavior, and installation environment, which allows for technical confirmation before deployment rather than relying on generic assumptions.
Connector and Cable Compatibility
Many application failures originate not from power capacity issues but from connector mismatches. MYLION's approach includes connector/cable matching to reduce selection errors, covering interfaces such as DC5521 input and DC5525 output configurations used across its product lines.
Battery Capacity and Runtime
Battery energy, measured in Wh, determines how long a router or CPE device can continue operating during an outage. Depending on the deployment scenario—short-term outages versus long-duration outages in residential or remote areas—different battery capacities are appropriate.
Peak and Startup Load Considerations
Some routers and gateways draw higher current during startup or peak performance periods than during standard operation. A Mini UPS that only accounts for continuous current, and not maximum/peak current, may be insufficient for high-load CPE or gateways that exceed standard thresholds.
Platform Compatibility
MYLION's Mini UPS products are compatible with routers, ONTs, ONUs, modems, gateways, CPE devices, and security/CCTV equipment, subject to electrical verification for each specific model.
MYLION's Product Portfolio for Router Backup Power
MYLION offers a structured range of Mini UPS products organized by output characteristics, allowing project teams to match a specific router's requirements to an appropriate series.
12V Standard Series
This series targets entry-level to mainstream broadband backup needs. The MU26W is an entry-level 12V Mini UPS supporting 2.5A continuous current (3A maximum) in a compact form factor, with 18.72Wh battery capacity, a DC5521 input, and DC5525 output—suitable for telecom, ISP, and home networking use. The MU48W provides mid-range capacity at 29.6Wh with the same 2.5A continuous/3A maximum output and a center-positive DC5525 output, aimed at ISP and broadband network equipment. The MU68W extends battery energy to 44.4Wh with maximum output of 36W (12V/3A), positioned for professional ISP projects.
12V Long-Runtime Series
The MU635W and MU635L models are designed for long-duration power outages in residential or remote areas. These units provide 75.6Wh of battery energy while maintaining the standard 2.5A continuous/3A maximum 12V output, supporting prolonged service continuity for standard CPE devices.
12V High-Power Series
The MU65W addresses high-load CPE or gateways that exceed standard 2.5A thresholds. It supports a 12V DC input of up to 6A and a 12V DC output of 4A continuous/5A maximum (60W total), with 56.16Wh of battery energy—suitable for high-performance WiFi equipment and storage-integrated gateways.
12V High-Power Long-Runtime Series
The MU35W and MU35L combine high output current with maximum battery capacity, supporting 60W output (4A continuous/5A maximum) alongside 75.6Wh capacity. This series is positioned for professional gateways requiring both high peak current and long backup time.
12V + USB Multi-Output Series
For scenarios requiring simultaneous backup of a router and a USB accessory, the MUJ46 offers 12V DC output (1.5A continuous/2A maximum) along with dual 5V/3A USB-A and USB-C outputs, within an 18W total system limit and 37.44Wh battery energy—suitable for small office/home office (SOHO) setups. The MUJ435 extends this concept with 50.4Wh battery energy while maintaining the same 18W total output limit across 12V DC, 5V USB-A, and 5V USB-C ports.
AC-Input Dual Output Series
The ML1202AC is an AC-input dual 12V LiFePO4 UPS designed for managing two separate 12V devices from a single AC wall outlet, such as an ONT and router combined installation. It accepts 100–240V AC input and delivers dual 12V DC output (2A each; 24W total system limit) with 25.6Wh battery energy, eliminating the need for an external DC adapter.
Development and Project-Evaluation Directions
MYLION is also advancing two directions currently under development. The MUC85 is a USB-C PD Mini UPS intended for modern WiFi 6/7 devices requiring USB-C Power Delivery, with USB-C PD input (65W standard/100W max), two USB-C outputs (up to 20V/3.25A and up to 12V/2.5A), and 92.16Wh battery energy; it is currently available for project evaluation only. The MU248 targets 24V/48V telecom backup needs for higher-voltage wireless CPE and radio bridge equipment, using LiFePO4 chemistry, 48V/60V DC input, independent 24V (3A) and 48V (1A) outputs, a 100W total system limit, and 102.4Wh battery energy.
