Best UPS for Routers

The EnerGenie brand UPS is made in a black and white plastic case with clear operation indication. At the bottom of the front panel, there is a power button and several LEDs. They demonstrate the active mode, display the battery status — four intermediate marks — 100, 75, 50, or 25%, and warn of impending discharge.

The EnerGenie EG-UPS-DC18 is equipped with a block of three 18650 batteries with a capacity of 2.2 Ah. The battery pack is protected from overcharging and deep discharge, and has a quite fast capacity replenishment cycle — about an hour to 90%. At full load (18 W), the batteries will last up to 70 minutes, and an average router should work without power for 3 hours or more.

The model is meant for working with low-voltage consumers like surveillance cameras and home networking equipment (modem, router, etc.). The voltage switch with two options — 12 or 15 V — is intended to enhance application flexibility. However, there is only one DC output here, making it difficult to operate several devices simultaneously. Thanks to a multi-level protective system, connected equipment is safe from short circuits and power surges.

The downside is the absence of a power adapter for the UPS itself in the package. It is assumed that you'll use the adapter of the device you're making autonomous, and the DC input is standard — sized 5.5 x 2.1 mm.

The EnerGenie EG-UPS-DC18 is a balanced mini UPS with a good balance of charging time and runtime for low-voltage devices.

In the Voltronic Power brand lineup, the low-voltage UPS is the junior solution. It features a peak output power of 18 VA, so it can be recommended for standalone power of one or two devices, such as a router and a fiber-optic internet terminal (or a network switch). It comes with various interfaces for connection — three DC outputs at 5, 9, and 12 V, a USB-A port, and a POE port with adjustable voltage (two options of 15 or 24 V).

If you need a model ready to work with three consumers at once or powerful network equipment (a gaming router), you can consider the older version Voltronic Power DC1036P, which will be more expensive.

Like most counterparts, the model is designed in a flat form factor, does not take up much space (dimensions 32x160x102 mm), weighs about 300 grams, which increases mobility. Inside are lithium-ion batteries with a total capacity of 10.4 Ah, and on the body, in addition to the power button, there is a 4-level LED charge indicator.

In tandem with a regular home router, the UPS should provide up to 10 hours of autonomy. However, battery degradation in some cases occurs quite rapidly, resulting in a one-third reduction in overall autonomy after several months of operation, and then up to 50%. In any case, the Voltronic Power DC1018P 10400mAh 18 VA is a noteworthy UPS for low-voltage devices.

The mini UPS from the ColorWay brand is equipped with a lithium-ion battery with a capacity of 10 Ah. It can provide up to 10 hours of autonomy for a router, switch, or other low-voltage home device. The model also features a cold start function and seamless transition from AC to battery power and vice versa. The overall battery charging cycle should not exceed 2 hours.

The ColorWay CW-PB100LI3WT is primarily recommended for routers and IP cameras. For their connection, there are 5 outputs — three DC with different voltages (from 5 to 12 V), a classic USB-A, and a POE port with a voltage switch (15/24 V). The latter allows transmitting both data and power through one cable.

The total output power is slightly increased — 21 W, which allows powering a fairly powerful router or two less "greedy" devices simultaneously. Also, note the multi-level safety system, which includes protection from typical contingencies such as short circuits, and interference filtering.

For its price, ColorWay CW-PB100LI3WT is a good UPS for routers, surveillance cameras, etc.

The mini UPS of the Eaton profile brand is designed to ensure uninterrupted operation of versatile low-voltage electronics. Thanks to an output power of 36 W and support for four operating modes — with voltages of 9, 12, 15, or 19 V — the versatility of the model is increased. It is compatible with simple IP cameras, routers, or TV set-top boxes, as well as slightly more complex devices like network gateways.

Plus, for convenient connection, the Eaton 3S Mini 36W comes with 4 DC connector adapters, including the most commonly used 5.5 x 2.5 mm, as well as rarer adapters — 4.75x1.7 and 3.5x1.35.

The UPS is a neat box with dimensions of 96x30x136 mm, weighing less than 400 grams. Inside are two Li-ion batteries with a capacity of 2.2 Ah each. To charge them to 100%, it takes about 4 hours, and then at full load (36 W) it will last only 11 minutes. But in less loaded scenarios, it's much more optimistic: up to 5 hours for an IP camera or 120 minutes for a powerful router (at least with support for 5 GHz).

In operation, the model will not cause acoustic discomfort — at a distance of 1 meter, the noise level is 25 dB. Everything is also easy and simple in terms of visibility. A set of four LED indicators will help you select the operating mode and then display the remaining battery charge.

The downside of the UPS is having only one DC output, so you cannot connect 2 devices with different voltages (and for identical voltages, you'll need special splitters). In any case, the Eaton 3S Mini 36W is a worthy solution from a reputable UPS manufacturer.

A newcomer in 2026 from the YEPO brand, this is a UPS for routers and advanced class routers. This status is confirmed by the presence of a LiFePO4 battery, which outperforms lithium-ion counterparts in terms of durability and safety — it's designed for more discharge cycles, not prone to overheating, and better tolerates low temperatures. The battery capacity is 12 Ah, which, depending on the connected devices, will provide 6 to 12 hours of backup power.

Another feature of the YEPO UA-112969 is the presence of two USB ports, including one Type C, which expands versatility and allows the UPS to charge various mobile devices.

The power of the model is 36 W, which is enough to power 3 or 4 devices, or, for example, a tandem of a gaming router and an IP camera. The versatility of the UPS is supported by a wide range of operating modes — with voltages of 5, 9, 12, 24, and 48 V. To that end, the model provides three DC outputs and a POE port with a voltage switch (between 48 and 24 V). Therefore, the UPS is compatible with virtually any router, various modems, network equipment, and POE devices.

Additionally, it offers charge indication, basic safety systems, and microprocessor control to increase overall reliability. The downside of the model is the high price, but if you want a router UPS with Type C and LiFePO4 on board, the YEPO UA-112969 has virtually no competitors.

The TriniX brand UPS is notable for having four outputs to connect various devices — a router, surveillance camera, media converter, modem, etc. It features one DC port with a voltage switch of 12 or 9 V. Additionally, the model includes USB-A and Type C ports, which allow charging smartwatches or other small modern gadgets. Complementing this setup is a LAN port with POE technology support: one Ethernet cable can transmit both data and power.

The UPS has a nominal power of 18 W, which is standard for low-voltage solutions. The device is moderately weighted (about 600 grams) and measures (3.5x20.6x12 cm), making it easy to find a suitable spot for it or, if necessary, hide it from prying eyes. Additionally, it features simple but informative operation indication with seven LEDs. The package includes a power cable for the UPS and a splitter for two DC outputs.

Among the model's advantages is its battery, which has a large capacity of 20 Ah and is made using LiFePO4 (lithium iron phosphate) technology, which surpasses lithium-ion counterparts in reliability and durability. However, the UPS's price is also high. Overall, the TriniX TRX-MUPS-1812 is an interesting UPS with a capacious battery and a good set of ports.
