UPS Backup Battery - 12V DC Power Bank Portable Charger for Smart Home Hub, Router, Modem, Raspberry Pi, Smart Phone, LED Lights, Security Camera - 7800mAh - 12V / 5V USB Dual Voltage

Bought this to supply power to my secondary Wyze Wi-Fi mesh router. My primary router is on a normal UPS, but the secondary is in a closet where I don’t need a large UPS.Plug your Wi-Fi power into this battery backup and then the supplied power cable from the unit to your Wi-Fi and it works. It charges itself when it needs to and when the power goes out there is no interruption. You can test it by unplugging the power from the wall socket, and the power stays on for the Wi-Fi. It mounts to the wall with one screw (included in box) or you could double side tape or Velcro it.

Update ** I have had a few power failures now, including a four hour outage while they wiredcin my new transfer switch. Never had a issue with my mesh satellites going offline including the four hour outage. The mesh router master, switch, AirTV, and cable modem are backed up off a traditional offline battery UPS. So on a power bump or outage my Internet/wifi never goes down. Now that I have a home standby generator I should have Internet until Spectrum fails.I just installed them and I have not had a power failure yet, so take that with for what it's worth. I got them for the satellites for my mesh WiFi to keep everything synced up even during a short outage. I have a traditional battery backup for by cable modem, router master, and network switch. These are small so they are great for the satellites which are tucked away. So far so good.Update: Our power was off for 3 hours last night, but our wifi mesh network stayed up for the whole outage. I also experimented and shut off the plug strip to one satellite, no issue, the satellite did not see the outage. So call this a success story

Installed easily on our modem/router. Kept our wifi connection running during recent storm outages.

This comes with a male end to male end connector, but that didn't help when my modem is a bigger port. I could not find anything with two different sized ends. And my Frankenstein attempt to piece together adapters failed to fit as well. So this has been absolutely useless for over a year now.

I like that this has a 12V DC out barrel connector, and that it is very small. The mounting option is nice, and that it doesn’t beep on battery power was essential.But, I was hoping this would work for a certain application and it doesn’t.We bought an AC powered automatic pet watering bowl, but don’t have an outlet near the pet bowl. The AC power of the bowl is a transformer to 5V USB-A. My plan was to get two of these and rotate them between charging and powering the bowl. But because both the power source and the water would not last as long if it was constantly running, I also got a pass through USB-A male to USB-A female motion detector, so the pump would only run for a minute or so with motion nearby.It works well for a few tests, but then a few minutes later I walk by and the water doesn’t come on. This device has powered itself off, even though if I plug it back in for a moment, and then reconnect to the motion detector it works - for a few more minutes. My best guess is that some safety circuit in this device is sensing the change from low power draw (sensor) to relatively high power draw (1.5w pump) and cannot figure out why the power draw is oscillating so it shuts down. I had the very same problem with “traditional” USB-A power banks when I tried them first, but I bought this product because it claimed to be a UPS.The other thing that this device lacks, that is important for at least my application and maybe yours, is that there is no external indication of how much power remains. My traditional USB-A power banks at least had 4 LED’s so I knew when I saw they were at one light left, I could swap them out.I still haven’t decided whether or not to keep this. I could repurpose this to my router cabinet as a sort of backup power to the backup power. I presume if the devices attached are drawing kind of predictable, mostly level power, it will stay on until the battery empties, after the big lead acid UPS I already have is done.

I added this to the fiber optic receiver in my garage. just needed something to keep the receiver from powering off during outages. this works great. my internet now stays up 100% during power outages (inside router is also on battery backup). very easy to install.

Tengo problemas de apagones pero gracias a la batería no he perdido la coneccion con internet pues mi módem no ha perdido alimentación eléctrica .

I have both my T-Mobile gateway and router connected to this battery backup. Together they draw around 20 watts. During a power failure the Konnected keeps them going for 1-1/4 hours. Excellent small and convenient backup solution. Just one annoyance; the LED indicators are super bright. I covered each of them with LED light dimming stickers, resolving the issue.
