Shanqiu Mini UPS Battery Backup Uninterruptible Power Supply for Router, Modem, Security Camera with Input AC Output USB 5V DC 5V 9V 12V (37Wh)

You never know when you need insurance until the day something goes wrong. That’s exactly this backup. The other day power went off. And I never lost internet thanks to having one of this units connected to my router. Best investment ever. I planning to get second unit.

I recently purchased this UPS, and it has exceeded my expectations. I bought this for my family that live in a country tant has a lot of electricity problems they have frequent power outages in their area, and this device has been a game-changer. It provides uninterrupted power to their computer and modem, preventing data loss and keeping their connected during blackouts.The setup was simple and straightforward. It has multiple outlets, which allows their to protect several devices simultaneously. The battery backup gives me enough time to save their work and shut down the system safely. Additionally, the surge protection feature offers extra peace of mind, especially during storms.One of the features I appreciate most is the automatic voltage regulation (AVR), which stabilizes power fluctuations and protects sensitive electronics. It operates quietly, and the LED display provides clear information on battery status and power conditions.Overall, this UPS is a solid investment for anyone who wants to safeguard their devices and avoid unexpected shutdowns. I highly recommend it!Pros:Easy to set up and useReliable battery backupSurge protection and AVR featureQuiet operationCons:Battery life could be longer for extended outages

I've actually bought several of these backup batteries. I like them because they essentially take the place of the wall wart transformer some devices come with, so when the power goes out, they're way more efficient when providing backup power.The pluses:As mentioned, they essentially take the place of a plug-in transformer for devices up to 12 volts. So, unlike a normal backup battery plug strip, they directly supply DC power to the device. What that means is the backup battery doesn't have to convert AC to DC to charge the battery, then convert the battery DC back to AC to power the device. It means instead of running for as little as 2-5 minutes for a small computer or maybe and hour, in the case of running an internet router, it can run potential for multiple hours.That leads to the second plus, which is that it can do this in the form factor that's maybe the size of a couple of decks of cards placed side by side. That means you can easily put it wherever your device is, unlike battery plug strips that are hard to place anywhere that isn't the floor, shelf or a desk.As I mentioned, I have several of these running my internet router (the modem still needs a regular battery plug strip due to the internal transformer), my security camera DVR, the security cameras, a micro PC and a couple of other small devices I want to have seamless power for.The nice thing is, these batteries will either run a device that uses a normal round DC plug or those devices that use USB adapters since it has a USB power port.The minuses? I haven't really found any so far, other than you really should use one for each device instead of trying to run multiple items on one. I do run my security DVR cameras all off one, but they don't use much power so it works well for that. Anything else, I have a battery for each item.

Only just got this. I really don't like what I consider throw away ups units from the common manufacturers such as APC and their current lithium ion ups is laughable with next to no compatibility out of the box. It was too crazy to try to figure that one out. Instead, this one here comes exactly with everything I needed plus more.Actually, so far am impressed by this as a ups. Will update this review in time.Decided to start the review today as I want people to understand that this will not have a warranty like APC, etc. I see that one person got a replacement when one failed after some months. That is great but you shouldn't expect anything and should expect less than a company like APC with U.S. warranty laws. If this company does as good or better than APC would then that is great but that's the risk here. The laws are not the same.That said, its not that eg APC products are great anyway. I avoid all those typical companies with ups's unless there's no other choice.But, coming back to this product, it looks great and functions well. One end of the included y cable fits exactly the voip device and the other end, I just add one of the included adapters to it to fit the other device.I used a kill-a-watt meter device to test the wattage of the devices to attach here and made sure it comes well under the max wattage of this ups with extra room.However, dc is quite particular so you should be careful or you will wind up with under voltage, over voltage, wrong polarity, or something else that isn't good. This product could be further improved to provide more compatibility and safety out of the box.Press the power button and the ups goes on. The device(s) power on. Plug the ups in and it regulates the battery and unplug it and the device(s) continue to function without loss of power. Works as expected.The ups is nearly cool to the touch once the battery tops off. Warm while charging.Full battery use test with about 14 watts came in at just over 3 hours. Full battery charge came in at about 5 hours 30 minutes.So far, its a great buy. I'm sure its possible some people will find reasons to give it one star but the same can be said for any product. I rate an APC ups sitting failed right now that way especially since their only comparable ups for sale today is ridiculous in comparison.But, I only just started testing this. Check back in time to see if my opinion changes.Also, you might forever miss the shipping film over the light section. Nice added touch to the product to keep it from scratching until you get it.Update 1: Heading towards 5 months. Still working great. Next update should be after a year or more.Update 2: Nearly a year. Still great. No fires lol. Actually, I'm definitely happy with it and will buy more in the future.Update 3: Still works great over 2 years now. Handles every power flicker and short outage thrown at it.To add. Some 1 star reviews will definitely not have ever considered the fact that what you plug into a router determines the amount of wattage. If you have a computer plugged into it and are using a lot of Internet for example then the wattage consumed goes up greatly. Etc. Lots of people will be getting things wrong here. If the wattage goes above the ceiling then that's not good here at all.
