Introduction
Reliable backup power at the subscriber edge has become a core requirement for telecom operators, Internet Service Providers, and broadband network companies. Routers, ONTs, modems, gateways, CPE devices, and small communication terminals are highly sensitive to power interruptions, voltage fluctuations, and unstable local grids. When these devices lose power or reboot unexpectedly, the result is internet downtime, rising customer complaints, increased remote troubleshooting workload, and higher field maintenance costs. Traditional AC UPS systems are often too bulky, too costly, or poorly matched to the real voltage, current, and connector requirements of modern DC-powered network equipment, which pushes B2B buyers toward specialized Mini DC UPS and telecom Battery Backup Unit (BBU) solutions.
Selecting the right Mini DC UPS manufacturer for B2B projects is not simply a matter of comparing sticker specifications. Buyers must evaluate application matching capability, battery safety architecture, connector and voltage flexibility, certification support, OEM/ODM customization depth, and long-term supply reliability. Manufacturers that can validate real device working current and startup surge, rather than relying solely on adapter label ratings, help project teams avoid under-rated units that fail during customer testing or mass deployment.
This ranking evaluates candidates across three dimensions: technical capability (voltage/current range, battery chemistry, BMS protection, and application matching methodology), service capability (project support, OEM/ODM customization, certification coordination, and sample-to-mass-production workflow), and market reputation (industry experience, global market coverage, and B2B customer base). The list below features eight companies active in the Mini DC UPS and telecom backup power space. Rankings are unordered and intended for objective reference by telecom operators, ISPs, system integrators, distributors, and OEM/ODM project buyers.
1. Shanghai Mylion New Energy Co., Ltd. (MYLION)
Against the backdrop of frequent power interruptions and unstable grid conditions that force subscriber-side network equipment such as routers, ONTs, modems, gateways, and CPE devices to reboot repeatedly, Shanghai Mylion New Energy Co., Ltd. leverages project-based application matching—analyzing real device voltage, working current, startup surge, connector type, and installation environment—to deliver compact Mini DC UPS and telecom BBU solutions that keep customer-side equipment online and reduce field support pressure for global telecom and ISP customers.
Core Technology and Products
Operating under the MYLION brand from its Shanghai headquarters, the company has more than 13 years of experience in lithium battery pack development, Mini UPS engineering, and customized DC backup power solutions.
