## Description

Eaton 3S Mini UPS: Safe service continuity of connected devices during power outages. An affordable and compact DC UPS that provides power to your internet router, IP camera, home assistant and smart controller. Designed to maintain connectivity: Connect and operate important devices (such as internet gateway, IP camera, smart home controller, personal assistant, etc.) during a power outage. Maintains the ability to remote control connected devices without loss of power (IP camera) Internal Circuit Overcurrent Protection Adaptivity: Choose from 4 output voltages to meet the power needs of critical applications and 4 output connector types that meet the requirements of the device. Simple: Easy to read LED indicator provides information about selected output voltage and battery level Cold start feature means that the 3S Mini can be used as a battery bank. 【Compact and Quiet】The 3S Mini replaces the included power source for your device, ensuring power protection without additional devices. The ultra-compact, silent, and stylish design allows the 3S Mini to blend well with your home or bath.

Review: The second chance ones have a high probability of damaged battery cells. I had to replace those,which is possible when you take it apart. But consider that it has no, again no, protection for deep discharging of the battwry cells inside. (2 x 18650)
Review: I own three of these units. Two worked great during a power cut yesterday, but one of them instantly dropped the output power. They are all around 12 months old. The one unit which failed had actually been fully discharged once, several months ago during a previous power cut. The other two units did not fully discharge, because they have very light loads (~3 watts vs the ~9 watts attached to the failed unit). Both of the lipo cells inside (TP LI-ION 3.7V ICR18650 2200mAh MH46259 UD020) now read at roughly 0.125 volts, so my /assumption/ is that these are unprotected cells and the unit itself does not have a low-voltage automatic cutoff. This is extremely problematic, because whenever there's a lengthy power cut, there is a solid risk that the unit itself will then be bricked unless you want to manually replace the lipo cells inside. So I'm afraid I need to give the "overall rating" as just one star because of this. Sorry, Eaton. Unless I'm mistaken and the one unit is faulty, then you will need to release a revision 2.0 which includes proper cell protection. Ideally they would auto power-off at, say, 20% power remaining. Perhaps even make the percentage/voltage configurable with a DIP switch somewhere, but obviously a DIP switch would add slightly to the materials cost & the plastics would need redesigning, so a straightforward X% cut-off would be the most reasonable thing to implement.

*by S***E on January 6, 2022*

Edit. 2 years later I’ve repeated some full discharge and recharge tests, including discharging it at the max rated 36Watts and unlike others still have has no problems with the recharge sequence. The failure of the low cell voltage protection reported by some hasn’t occurred on my unit. This Eaton3S and the APC CP12036Li remain the best options available for anyone looking for a small DC UPS with a recognised name. Nicely made mini UPS from a recognisable name, with a 2 year warranty its got the feel of a quality product. Well documented. It has some nice features, like switchable output voltage level and a relatively high supply rating of 36Watts. I've run some12V load tests when on battery and the output voltage only dropped from 11.9V@0.5A to 11.3V@3A. The DC output level was also maintained well as the battery ran low . By including the AC/DC conversion inside the unit there is only space to include 2 off 2200mAH lion cells, so overall capacity is a fairly small but usable 11.9Wh (measured). So it should be able to run a typical small router (5-6Watts) for around 2hours, that's probably long enough for most typical mains power interruptions. The battery recharge rate is a relatively low 4Watts so once mains power is restored it does take around 5Hours to fully recharge . Once fully charged the UPS appears to use <1W to manage its own functions To make it a better prospect than its competitor MiniDC UPS What it ideally needs is either larger internal batteries or perhaps the ability to recharge from an external powerbank. The case would benefit from some mounting holes and there's also no audio warning to indicate 240V power failure. It is however one of the few MiniDC UPS that I'd be content to leave running unattended in my house 24/7/365.
