The best UPS for routers

The EnerGenie uninterruptible power supply is made in a black and white plastic case and provides a clear indication of operation. 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%, warn of imminent discharge.

The EnerGenie EG-UPS-DC18 UPS is equipped with a block of three 18650 batteries with a capacity of 2.2 Ah. The battery is protected against overcharging and low discharge, as well as a fairly fast capacity replenishment cycle - about an hour for 90%. At the same time, at full load (18 W), the battery will last up to 70 minutes, and, let's say, the average router should "work" without power for 3 hours or more.

The model is designed to work with low-voltage consumers such as video surveillance cameras and home network equipment (modem, router, etc.). A voltage switch with two voltage options - 12 or 15 V - is designed to increase the versatility of use. However, there is only one DC output, which makes it difficult to work with several devices at the same time. Thanks to the multi-level protection system, the connected equipment is not afraid of short circuits and voltage surges in the network.

The disadvantages include the absence of a power supply unit for the UPS itself in the delivery set. It is assumed that you will use the adapter of the device that you will make autonomous, and the DC input here is standard - with dimensions of 5.5 x 2.1 mm.

EnerGenie EG-UPS-DC18 is a balanced mini-UPS with a good ratio of charging time and battery life of low-voltage devices.

The PowerWalker brand UPS has a form factor of a remote power supply unit (PSU). It is really small (even against the background of analogues) - 68x42x74 mm, comparable in size to a regular router PSU. This means that it does not need to look for any special place to place it.

PowerWalker DC SecureAdapter 12V works very quietly : background noise of up to 30 dB will not interfere even if the UPS is very close. The model also has a simple LED indicator that will tell you about correct operation (green glow), imminent discharge (fast blinking) or errors (red color).

The UPS is compatible with small electronics - routers, switches, IP cameras, decoders, smart home control panels, media players and other devices with a voltage of 12 V. There is one standard DC output with a connector size of 5.5 by 2.5 mm directly for connecting them. At the same time, the maximum power is limited to 25 W, which generally allows for simultaneous backup power supply for several devices (but through splitter cables, which must be purchased separately).

The additional features of the model include not only a basic protection system (against overload and short circuit), but also a high-quality output signal in the form of a correct sine wave.

A 2.6 Ah lithium-ion battery from Samsung is responsible for autonomous power supply. At maximum load, it will provide about 25 minutes of operation without electricity, but the average router should work from 2 to 3 hours, which can be considered the lower limit of the norm for force majeure situations.

Another advantage of the UPS is its low price compared to its main competitors. Therefore, the PowerWalker DC SecureAdapter 12V is a good option without overpaying to power one low-voltage device.

The mini-UPS from the Voltronic brand features a high-quality battery. For example, it uses lithium-iron-phosphate LiFePO4 technology, which surpasses Li-ion in terms of working life and readiness for difficult operating conditions. At the same time, the battery capacity of 8 Ah should be enough for several hours of backup power supply for low-voltage consumers in practice.

Voltronic Power Eco-1825 also has a multi-level security system, including protection against overload, overcharge, and short circuit. All this also has a positive effect on the overall reliability and durability of the UPS.

The UPS has three DC outputs with different voltages - 12, 9 and 5 V. In addition, there is a traditional USB A port and a LAN connector with a POE function and the ability to select voltage - 24 or 15 V. Thus, various low-voltage devices can be connected to the model, including a router, video surveillance cameras, mobile gadgets, GPON terminal. Simultaneous power supply of several consumers is also possible, however, it should be taken into account that the nominal output power is 18 W.

The device has an informative indicator, does not take up much space (dimensions 33x160x105 mm), and weighs a moderate 400 grams.

Voltronic Power Eco-1825 is a great low-voltage UPS, especially if you want lots of ports and a long-lasting battery on board.

The Marsriva brand UPS is the junior solution within the branded KP1 line. It is equipped with a lithium-ion battery of 8000 mAh (capacity 29.6 Wh) and has a nominal output power of 18 W. Let's say the KP1 Plus version can offer a battery of twice the capacity, but it is also more expensive.

The built-in battery in Marsriva KP1 EC is sufficient for most low-voltage device backup power scenarios. If you connect a router, its autonomy averages over 6 hours, and, for example, a fiber-optic modem, it approaches 10 hours.

The uninterruptible power supply is equipped with 4 DC outputs at once, a pair of which has a voltage of 12 V, and two more - 9 and 5 V. Such variability adds versatility and ensures compatibility even with the most non-typical low-voltage consumers. In addition, USB A is provided here, which, if necessary, will help charge a smartphone or other mobile devices.

In theory, 5 devices can be connected to the UPS at the same time, but given the average peak power and battery capacity, such a scenario is not very practical. However, there should be no problems with the simultaneous backup power supply of 3 consumers: for example, this could be a router, a GPON terminal, and a video surveillance camera.

The model is stated to be made of fire-resistant plastic. The body is compact (3x11x17 cm), not heavy (340 grams), and is supplemented with wall-mounting mounts. We also note the laconic control with LED indicators and a basic safety system - protection against overload and short circuit.

Marsriva KP1 EC is a noteworthy mid-priced mini-UPS with variable connection interfaces.

The debutant of 2024 from the YEPO brand is a UPS in a brick form factor with dimensions of 5x15x5 cm. In this aspect, the model is somewhat different from its analogues, but it will still be easy to use and will fit into any interior (thanks to the black color). On one side of the case there is a power button and LED indicator, and on the other - all the connectors. The kit includes a power cable and two adapters for connecting devices.

Inside the YEPO UA-112485 there is a fairly capacious lithium-ion battery of 10.4 Ah. It is stated that at full load (output power of 18 W), the battery will provide up to 480 minutes (8 hours) of autonomous operation. And if only one router is connected, it will withstand even longer blackouts.

The model provides a multi-level protection system, including interference filtering and all standard force majeure events - short circuit, overload, etc.

The UPS guarantees an output signal in the form of a pure sine wave, which is extremely important for devices sensitive to the quality of current. Here you can connect not only routers, routers, surveillance cameras, but also low-voltage audio equipment, IP telephony equipment, etc. For these purposes, three DC outputs of 5, 9 and 12 V are offered at once, as well as a LAN connector with the POE function (two voltages are supported - 24 or 15 V). In addition, there are two USB at once, and not only the classic one, but also type C with an output power of 15 W (5 V 3 A) - for quick charging of mobile gadgets.

YEPO UA-112485 is slightly more expensive than its mid-range counterparts, but it also offers a number of advantages that are worth paying extra for.

The mini-UPS of the Eaton brand is designed to ensure uninterrupted operation of a wide range of low-voltage electronics. With an output power of 36 W and support for four operating modes - with a voltage of 9, 12, 15 or 19 V - the model's versatility increases. It is compatible with both simple IP cameras, routers or TV set-top boxes, and slightly more complex devices, such as network gateways.

Plus, for convenient connection, the Eaton 3S Mini 36W package includes 4 adapters for the DC connector, which include the most common 5.5 to 2.5 mm, as well as rarer adapters - 4.75x1.7 and 3.5x1.35.

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

The model will not cause acoustic discomfort in operation - at a distance of 1 meter, the noise level is 25 dB. With clarity, everything is also easy and simple. Four LED indicators will help you select the operating mode, and then show the remaining battery charge level.

The disadvantages of the UPS include only one DC output, so you definitely can’t connect 2 devices with different voltages (and for devices with the same voltage, you’ll need special splitters). In any case, the Eaton 3S Mini 36W is a solid solution from a manufacturer with a good reputation in the UPS market.
