Eaton 3S Mini UPS, we tested this device with 2200 mAh battery

The Eaton 3S Mini UPS  is a compact uninterruptible power supply designed to save us when the electrical network fails. The manufacturer has had the courtesy of sending one of these units to our newsroom, so we are going to share with you the experience of using the small UPS . We encourage you to discover the usefulness of the Eaton product through the review . An ideal accessory to keep critical system devices always active, such as a FRITZ!Box 4060 router .

Presentation of the Eaton 3S Mini UPS

The small 3S Mini is a practical UPS from the Eaton brand , dedicated to producing a wide range of products and services. The company offers everything from fuel-efficient systems to power chain management tools and components that safely guide commercial aircraft. It may be surprising that managing at such levels, the firm has in its catalog a device, a priori, so simple. But Eaton distinguishes itself by finding new ways to increase the value of the products and services they offer to users.

The Eaton product comes to us in a simple box that is no different from any accessory that we can find on the shelves of a computer store. The packaging has a bright white background , where the blue color provides the necessary contrast to break the monotony of the design. The front of the box presents a reduced-scale image of the UPS , profusely surrounded by texts, all in English , that point out salient aspects of the device.

On the front of the box, the manufacturer has arranged a kind of mini-guide of the device. Eaton exposes, in a very graphic way, how the UPS is connected and works , in addition to showing us some of the elements contained in the package. The box has a simple upper opening, after cutting the adhesive seal that keeps it closed. A cardboard separator keeps the elements contained inside safe from friction between them. Inside we find the UPS in question; an envelope with several barrel-type connectors ; the power input cable ; and a quick guide booklet .

3S Mini Design

When extracting the UPS Eaton 3S Mini we like the sensations that the product transmits. The quality of the accessory is appreciable , and it is surprising to be much more compact than we supposed. It is not a heavy device, but it is felt. The device weighs 370 grams , so it is easy to carry around. The tower format with rounded edges, designed to be placed horizontally , is concentrated in rectangular dimensions of 13.6 cm deep , 3 cm high , and 9.5 cm wide .

The device sports an attractive appearance by combining the strong contrast of white with black in the halves of its chassis. The casing is made of plastic , and the manufacturer’s logo stands alone on the top. On the front it has, turned towards the extreme left, a set of LEDs and the only UPS button . Just below each of these elements are engraved the symbols that indicate the function and the voltage . The truth is that being in the black part of the chassis, it is difficult to appreciate them.

On the opposite side of the button and lights is the connector for the power cable. The power cable for the other devices also comes out of this area. It is a fixed cable, unlike the one that connects the UPS to the electrical network. Finally, if we turn the device over, we will discover that small rubber feet have been placed on the base to ensure its location on any surface.

Device Features and Functionalities

The Eaton 3S Mini UPS is intended to keep a critical appliance running when a power outage occurs, long enough to weather the situation. Compared to the usual proposals, this model is distinguished by its small format, which allows it to be installed in limited spaces, and its very silent operation .

Of course, due to its small size, its use is limited to the field of peripherals with low consumption. The UPS offers us a power of 36 W , with the possibility of adapting the output voltage to 9V , 12V , 15V and 19V , with a maximum intensity of 3A . Inside it has a 2,200 mAh Li – Ion battery , capable of holding simple devices such as an IP camera for up to 5 hours , or keeping a router active for around 40 minutes .

This device is very easy to use. First we select among the included connectors the plug that adapts to the device that we are going to feed. When turning on the UPS , we choose the appropriate voltage by pressing the button, until the LED that marks it lights up, and everything is ready so that when the power fails, the 3S Mini battery comes into play .
