Selecting a Mini UPS for ONT, ONU, and router projects involves more than just comparing battery capacities. For telecom companies, ISPs, and system integrators, the right choice depends on several critical factors—including device compatibility, power requirements, deployment environment, backup expectations, and supplier reliability.
A Mini UPS that performs well in one scenario may be entirely unsuitable for another. That’s why a project-based approach is essential to ensure smooth deployment and long-term performance.
Mylion offers a wide range of backup power solutions specifically designed for various telecommunications and network applications, to meet the actual needs of network infrastructure.
Match Output Voltage and Current to Your Devices
Different ONT, ONU, and router devices have varying power input requirements. Common voltages include 9V, 12V, 15V, 24V, or USB-C PD. While some devices operate with low continuous current, others require higher startup current or sustained power during heavy data traffic.
If the output voltage or current does not match, the backup system may fail to power the device—or worse, cause damage.
- For the standard deployment of 12V/1A or 12V/1.5A ONTs, the Mylion MU26W Mini UPS (with an output power ranging from 12W to 18W) can provide the necessary stability without causing unnecessary increase in size.
- For high-performance routers or multi-device configurations, you may consider using the MU35 Mini UPS (with a 5A output) or the MU248 Mini UPS (suitable for non-standard voltages).
Mylion’s Mini UPS series offers a wide range of output configurations, including multi-voltage and dual-output models, ensuring compatibility with diverse CPE (customer-premises equipment) setups.
Calculate Total Load Power Accurately
The mini UPS specifically designed for a single ONT is quite different from the UPS that supplies power to both ONTs and routers. Understanding the overall wattage load is crucial for selecting the appropriate backup capacity and output design.
In some projects, a single device must support dual-device backup functionality, while in others, it might be necessary to power both routers, ONUs and IP phones simultaneously.
Mylion offers personalized power capacity planning services to meet your exact electricity demands, helping you avoid using systems that are either too small or too large, thereby reducing unnecessary costs or increasing unnecessary complexity.
The Mylion MU35 Mini UPS is an industry-leading product designed to meet dual-output requirements. Its power consumption ranges from 30W to 50W, and it can simultaneously support the use of optical network terminals (ONT) and high-performance routers.
Determine the expected backup time and capacity
The backup requirements for ONTs, ONUs, and routers vary depending on the situation, ranging from continuous operation during short power outages to critical operation for several hours. The duration of operation depends on the watt-hour (Wh) capacity of the batteries and the actual load consumption.
- For home broadband configurations that require a backup time of 2 to 4 hours, the MU48W or MU68W Mini UPS is an ideal choice, achieving the best balance between cost and performance.
- For ISP on-site deployments that require continuous operation throughout the day, the MU35 Mini UPS is the ideal choice.
- For remote or unstable power grids, the Mylion MU35 Mini UPS can provide long-term uptime guarantees for enterprise-level ONTs and router clusters
Verify the compatibility of the connector with the port
Telecommunication projects often involve different DC plugs, cable lengths, polarity specifications, or multiple output ports. Some installations also need to support PoE (Power over Ethernet) or USB-C functionality.
If the design of connectors is overlooked too early during the planning stage, it may lead to difficulties in the installation process or equipment failure on site – even if backup equipment is technically feasible.
Mylion supports customized cable design, multiple output configurations, and port personalization settings to ensure a perfect fit for your specific installation environment.
Considering product reliability and intelligent battery management
In large-scale telecommunications deployments, inconsistent quality may lead to high maintenance costs and service disruptions. For ONT and router backup projects, uninterruptible power supply equipment must operate in a 24/7 standby mode and respond promptly in the event of an unexpected power outage. This requires:
- Intelligent Battery Management System (BMS): It can prevent overcharging, overdischarging, short circuits and extreme temperature conditions.
- Encapsulation material: Flame-retardant ABS casing, ensuring a safer standby state in daily use.
- High-quality battery cells: Standard lithium batteries have good safety, while lithium iron phosphate (LiFePO₄) has superior safety compared to standard lithium-ion batteries.
Mylion’s uninterruptible power supply products have been meticulously designed and possess industrial-grade reliability, ensuring stable performance during large-scale production and on-site deployment.
Ensure 100% Testing and Quality Control
Buyers should look beyond product specifications and ask: Is every unit tested before shipment?
For telecom and ISP projects, 100% functional testing significantly reduces field risks and improves batch reliability.
Mylion adheres to strict quality control protocols, with full testing on each unit to guarantee performance before delivery.
Confirm Certifications and Compliance
Depending on your target market, compliance with standards such as CE, FCC, RoHS, UN38.3, IEC62133, and IEC62368 may be required. For telecom and ISP projects, certification readiness can directly affect project approval, procurement, and customs clearance.
Mylion ensures that all Mini UPS products meet relevant international safety and environmental standards, supporting smooth project execution globally.
Evaluate Supplier Capability and Partnership Potential
A reliable supplier should do more than simply deliver products. Key considerations include:
- Ability to support OEM or ODM requirements
- Experience with telecom tenders and large-scale projects
- Flexibility in cable design, labeling, packaging, and output configurations
- Stable production capacity and responsive technical support
Mylion acts as more than a vendor—we are a long-term project partner, offering end-to-end support from design and prototyping to mass production and after-sales service.
