OTE sent it to me for the router..... I tried it and it lasted 6 hours with the router on! Without being plugged in, so what's better?
3-2023 with interruption and the speedport smart on it lasted 2 hours. Everything is ok.

Although it states that it is a 2amp router, the comsote router still malfunctions even when it is plugged in. Low speed, disconnections, freezing. In a few words, for me who wanted it for the router, it is a waste of money.

  This review is about a variation of the product

  I have it for about 2 months, it doesn't sound at all, it is the size of a router, it does exactly what it says, I have put it in a router and connected it to a home alarm, it lasts about 3-4 hours, even if it lasts 1 year I am ok to take it every year with a 30 that I got now.

  The best thing for power backup on the router. Small like a router and silent. I have had it for 5 years and I haven't changed the batteries yet. It lasts for over 5 hours during a power outage. And it's only for the router, of course. I have installed several of these without any problems. Finally, for those of you who claim that it doesn't work for you, your router probably consumes more than 15 watts and you need to buy the black one that is 30 watts.

  I got it to hold usb ip cam... In a test discharge through my usb it gave a little over 5000mah.... It doesn't look bad... Of course I would prefer the indicators and the button to be on top but ok....
  The only downside I noticed is that when it discharges, the charging circuit fills the batteries quickly in less than 1-2 hours approximately, which mainly makes it heat up when charging and possibly reduces the battery life over time....
  This is good because you have the device quickly ready for use again but.... Let's see how long the batteries and the charging circuit will last....
  The other downside is that it doesn't have 7.5 and 5v at the back but only 9 and 12v...
  Also from what I understand this one provides up to 2A in the usb and in the back socket at 9 and 12v up to 1A but not simultaneously...
  If you want more in the back socket then look for models with more wattage....
  Finally, the 15watt is total for both ports.... So if we assume that we draw 1A at 9-12v from the back, which is 9-12watt, then there is little available power left for the usb....
  About 0.6-1.2A, meaning 3-6watt...
  It also claims that if the 15w limit is exceeded, it first turns off the usb and if the overload continues, it turns off everything...
  Personally, I haven't tried it...
  That's all for now...

  Excellent
  I have it for over 3 years and it hasn't had any issues, it performs perfectly when the power goes out
  it just doesn't have a long duration.. it's for a router.

  I have connected it to a 12V router that draws up to 1.5A of current. I unplugged it from the socket to test it, and it lasted for 3 hours, reaching 50%. Excellent.

  I had the previous one that OTE used to provide. It did its job very well. When I changed the router, I found out they stopped providing it. I got the same but a longer model. A week ago we had a power outage due to network restoration works, from 08:00 to 14:30. I had internet thanks to the UPS throughout the whole duration.

  Good mini UPS that will keep your modem on for a few hours. It has a 5V USB output so you can charge a device. It is worth it for emergency situations.

  After 2.5 years of good performance (maintaining power to the router and no internet drops when the power went out), it got tired. The battery no longer holds a charge.
  As soon as there is a slight power outage, the router shuts off and I have to wait for a reset.
  Of course, the warranty was only for 2 years, during which it saved me many times. I bought it again.
  It's worth the money for 2 years.

  Apart from the Cosmote modem, I also added the Cisco device that converts optical fiber into a network so that I have internet in case of a power outage. It works great, I left it for 15 minutes with the battery and it dropped to 50%-75%.

  I use three, two for two routers and the third for a security camera. Extremely reliable. They give me about 4 hours of operation for this use in case of power outage. I am satisfied.

  Very satisfied. It keeps my 9 amp router running for up to 4 hours. It doesn't overheat, it's quiet, and it has a sturdy construction. It's not cheap plastic. I recommend it!

  This review is about a variation of the product

  It is used to support a modem/router in case of power outage. So far, it has not presented any problems. Obviously, it heats up at times, especially during the summer months, but if it has sufficient ventilation and is placed in an open space, there is no problem. Its predecessor (15W or 20W) from the same company lasted 5-6 years, which is why it was preferred again.

  It lasted me 10 months. The batteries burned out and caused a short circuit. Chinese people who are marketing it as a Greek product. Stay away.

  They gave it to me from the telecommunications company to "keep" the router due to frequent power outages (I live in a mountain village). The batteries lasted only about 1 year.

  Better than I expected. I connected 2 devices, an ADSL Router & an NVR with a hard drive, both 12V. It supported them very well for about 3 hours during a power outage. It is preferable for such loads compared to a 230V UPS with an inverter, which loses power during voltage conversion and requires frequent battery replacement. I hope its battery lasts longer than the lead-acid batteries of traditional UPS devices.

  This review is about a variation of the product

  I bought it exclusively for the router. They provide only 6 months warranty for the batteries and 12 months for the motherboard. There was a power outage in the 3rd month and it worked fine. There was another outage in the 13th month and it shut down along with all the other devices, even though it appeared to be 100% charged and until then I was confident that my UPS was functional! When I contacted the company, their technician informed me that it would be better to throw it away because replacing the batteries would cost more than buying a new one and that they are aware of this device's behavior.

  It does the job just fine and at a very good price. I tried to reset it and the router lights didn't flicker at all.
  As for how much the battery life will decrease, that will become apparent over time.
  Overall, it's perfect for the job I need it for.

  This review is about a variation of the product

  I bought this specific device for power outages on Cosmote TV and Cosmote router. Indeed, when there was a power outage, it worked wonderfully BUT...
  The big problem was that every night the router would restart on its own, losing internet connection. At first, I didn't pay attention. The next day, the same thing happened, and the next day. Googling, I found that other LAMTECH UPS users had the same problem and they said to remove it immediately and put back their original power supplies. As an electronics expert, I can't understand why this happens, but I had no other solution but to try. I went back to the power supplies of the router and Cosmote TV, and since then I haven't seen the router restart on its own again. The comments are up to you...

  Value for money. When I received it, the battery was already charged at 100%. The installation is simple, plug & play. I use it for the new COSMOTE SpeedPort Plus2 router (12V, 2A). The review is about the 2A, 30W Lamtech. It just requires a little attention in choosing the appropriate UPS, given that the smaller 15W Lamtech (the white one) operates at 1.2A and obviously is not sufficient for this specific router.

  I have it for the router and the photo was taken during a real power outage, one of those that we often have in my area. It performs excellently without losing the connection for a second. It is exceptional for the job I need it for. As for durability, I don't have an opinion yet, time will tell.

  Update: After 4 months of use and after a voltage drop, it simply stopped working. I'm downgrading it from 5 to 3 stars and it will depend on the after-sales service if it will go down further...

  I have it for about fifteen days and it works perfectly and silently. It has two plugs for routers that take either a large or a small plug. I have tested it by unplugging the power and it keeps the VDSL router from Vodafone on for 4 hours.
