SKE Mini UPS 30000mAh Battery Backup & Surge Protector Uninterruptible Power Supply UPS for Router Modem PoE DC USB Type-C Ports Sirius

instad of a mini UPS, it feels more like a super handy large portable power bank. With a 30,000mAh capacity, it can provide enough charge for my phone to last a whole week of use. The Type-C fast charging is especially great, as it only takes 10 minutes to fully charge my phone. It's fantastic! It also looks great on my desk with its stylish design and is very pleasing to the eye. Additionally, it’s a good option for powering a router or gateway. I’m considering buying another one to keep at the office for outage during meetings, as it would be a great choice for my MacBook.The only downside is that the seller advises that for first use, you should fully discharge the battery while not connected to mains power. In my opinion, this is quite inconvenient and they could have set this up at the factory. However, their customer service is very responsive, and I have already discussed this issue with them. They assured me that it will be addressed in the future, so this is not a significant problem anymore. Overall, I highly recommend it.

I never drained the battery when using it for the first time and several weeks later the battery level was stuck at 80%. Fixed it by draining the battery. You'll notice is completely drained when the wattage output indicates zero.Giving 4 stars since, given the price, the need of calibration the first time is something I consider critical and it may happen again. Will update to 5 stars if I notice it won't need recalibration after 3 months minimum.

The media could not be loaded. Update April 2025 1 starThree months since draining the battery and then charging it fully, the UPS is doing the same as before. It is slowly losing its capacity to maintain a fully charged state. It slowly decreased from 100% down to 33%. I do not recommend this UPS.Update: January 2025 3 starsAfter using this for about 2 months, the UPS no longer provides enough power for my 12 volt cable modem, and the UPS recharges only up to 40-60%. This, even after draining the battery upon first use.So, I drained the battery 3 times before it got back up to 100% capacity. Now, it is operating "normally" as a UPS. Cross my fingers I don't have to go through the process of draining the battery again.---------Original review 4 starsThis UPS works well to back up my modem and router. It is smaller and lighter than a traditional sealed lead acid UPS.I have 3 devices that run on 12V barrel connectors that need back up, so I needed to buy another 12V cable (the package includes a cable that splits a 12V output into 2).The fan is a bit noisy.During a power outage, the battery lasted about 2.5 hours. The 3 devices I have use about 24 watts total.

Update: Advertised battery capacity is hogwash! Even after several discharge cycle the deliverable capacity is only ~5,500 mAhr as measured by a multi-battery charger using its discharge feature. Delivering 400 mA, this UPS lasted 816 minutes or 13-1/2 hrs. This equals 5,500 mAhr. Even accounting for internal conversion loss ~20% the actual battery capacity is ~ 6,600 mAhr not the hyper touted 30,000 or even close to 15,000 mAhr. At a nominal load ~650mA requires only 2-1/2 hrs to fully recharge. Therefore I'm dropping a star..Initial impressions are positive. Got this device as a backup to my fiber router. Most conventional UPS's deliver only120VAC output only, being fed internally with 12-24VDC battery power. Problem is most today's routers are powered by a 120VAC wall wart delivering 12VDC to the router. An AC output UPS suffers a tremendous efficiency loss going from 12-24VDC internally to 110VAC output then then the wall wart going from 110VAC input back to 12VDC output. The inverter circuit alone inside the UPS consumes >50% of available battery capacity, ill-respective of load.. My old AC output CyberPower UPS w/8Ahr lead acid batteries will only provide ~120min maximum at no load! With the router connected it lasts just over 60 min. Special note, which is why I gave it only 4 stars is because the 30,000 mA/hr advertised capacity is misleading, its really only 15,000 mA/hr. This is because the batteries are internally series connected to provide 24VDC. Still this device is a game changer. It should power my router @ 650ma for around 24hrs vs 1 hr. The primary reason I selected this device is because it uses LifePO4 batteries NOT lithium ion or especially Lipo or lithium polymer batteries which are FIRE HAZARDS!

This is an ideal UPS for backing up cable modem and router. The cable modem and router draws about 10 watts at 12V and supplied power plug worked well. It will power the internet equipment for about 10 hours in case of power outage. Unlike other UPSs, it doesn't have any inverters so additional power consumption of the UPS is minimal, Additional benefit is it shows the power draws of any equipment connected very accurately. The fan makes noises on;y during the initial charge of the battery. I would highly recommend using this UPS for backing up the power for modems and routers.

The media could not be loaded. Ups de alta calidad en un excelente empaque, su presentación elegante del producto, los cables pertinentes para conexión. Sencillo de instalar con pantalla LCD que te informa aquello que está conectado, nivel de carga de la batería y consumo. Su disipador apropiado para la ventilación de las batería de litio que permitirá una vida útil prolongada.CONTRA: Con el uso del producto se descalibra el controlador de nivel de carga. Es la 2da vez que se descalibra y se debe drenar completamente la batería para recalibrar.

Because these don't have inverters they are crazy efficient! I can run my router/modem for like 10+ hours in a power outage, which is awesome because most internet cables in the US are buried an un-effected by outages. A similar conventional UPS with an inverter would only last like 1 hour in my experience...Very cool, be sure to follow the instructions and do the drain/charge, I think I messed that up with one and it has some issues now, nothing serious just running at lower %s than my others...
