Excellent for its size and price. When the power is out, it keeps both a modem and a TP-Link camera running for over 2 hours. The plugs that come with it fit almost all devices with DC input and across the full voltage range.

excellent, it also has dual power supply for 12v

Use for router & optical fiber.
Includes a dual-output cable to connect both together, however it is a bit short and you need to have all the devices very close to each other.

Speed limit at 100 Mbps
I bought it to protect my network equipment (router / 5G antenna), but unfortunately the Ethernet ports (RJ45) it has are Fast Ethernet (up to 100 Mbps) and not Gigabit (1000 Mbps).
This means that if you run the data cable through the UPS for protection, the internet speed is necessarily “locked” at 100 Mbps, creating a huge bottleneck on any line above 100 Mbps or on a 5G connection.
As a DC power supply for the router it does its job, but the presence of 100 Mbps network ports in 2026 is a significant drawback. If you have a fast connection, its network ports are practically useless.

Very good purchase! Exactly as described, it arrived quickly and does its job excellently. I would definitely buy it again.

I have it and it has been working for a short time. It works as it should. A small problem is the short cables it comes with, especially for connecting to the socket.

very good. it does its job. my battery lasted exactly 3 hours. to be honest, I expected around 5.
update: on a router with a SIM it was causing problems and the internet had no speed at all. unfortunately, I removed it and now it’s useless.

Silent indeed but it should have a sound when the battery runs out
short power cable
lasts over 2 hours approximately with a 12 volt modem

New, it kept my modem on for 4-5 hours. Its consumption is about 3w/h. So about 26 kwh per year or 6.5€. I hope its batteries last 2-3 years

During short power outages of 5-20 minutes, the Speedport Plus modem remained operational without any problems and without the battery indicator dropping. During the last power outage, it powered it for over 5 hours before the battery ran out.

It appears to be a quality and sturdy construction, in no way does it look like a cheap Chinese product. Its size is like a compact modem with a bit more weight! It comes with a power supply cable and a cable that replaces the modem's transformer so it can draw power from it. It provides various power cables so it fits about 99% of all sockets! On it, there is an on/off button and a battery level indicator. Overall, very positive impressions—during artificial power outages by unplugging it, it powered a modem for 30 to 45 minutes (I didn't leave it longer) and everything was fine! A big negative for me is that on the back there are no slots to mount it to the wall with screws, so I had to use a strap to keep it nicely organized with the other items.

Very good value for features/price, with a maximum power of 36W, multiple outputs 12V, 9V, 5V (barrel and USB), passive PoE 15V and 24V, built-in power supply and large 10400 mAh battery. I connected it to a ZTE MC888 router and after two hours the battery had dropped by 25%, so I estimate a duration of about 8 hours. It gets warm on its left side, but I don't see its operation being affected.

I got it for the router, I haven't tried it yet in case of a power outage to see how long it lasts, I hope it does the job.

update: today there were two short power cuts and I continued to have internet... recommended
