  Until now (1 month) I haven't had any long-lasting interruptions, but I've had many brief ones, where I simply heard the beep of the UPS and the screen didn't even flicker, I continued working as if nothing happened

  I have had the UPS for about 1 year and it works exceptionally well. I haven't tested how long it lasts, but during this time I have realized that you don't need more than 2-3 minutes to shut down the computer, and the same goes for the UPS. What you need to be careful about is that every time you connect something, you need to check if the UPS can handle those watts or volts.

  Advice!! Don't be afraid to use it, it is very safe because that's what I did. For 2 months, I was trying to decide whether to install it, but I made a big mistake.

  Also, when it turns on, it makes a continuous beep and when the power goes out, it beeps every 10 seconds. When you call it, it is silent. I highly recommend it without hesitation!

  An affordable UPS that, however, costs 5 to 10 euros more than the much better PowerWalker Basic VI 800 STL: https://youtu.be/XpDZXc6wr88

  Full review (Hardware Busters): https://youtu.be/xfmJ-B3dS2E

  Standby power consumption: 9.475 W - High

  Idle power consumption: 10.067 W - High

  Charging power consumption: 13.191 W - Moderate

  Battery duration with 300W load: 60 sec, Very short!

  Power factor with battery load (300W): 0.816 - Low

  Active power with battery load (300W): 250 - 220.6 W - Low

  Battery switch time (AC Loss): 11.63 ms, 14.23 ms for clean signal - Slow

  Battery release time (AC Gain): 7.755 ms - Fast

  Output voltage: 229.50, Very close to ideal (230V) although it fluctuates between 227V and 232V

  AVR results: Good results here. The AVR does not allow voltages to drop below 191.35V (ideal would be above 200V) and to rise above 229.78V. Also, the lowest voltage that the UPS can handle without battery engagement is 164.5V and the highest is 273V.

  Internal fan: No

  Batteries: 1 x 12V/7Ah Fujian MinHua Power Source
  http://www.mhb-battery.com/upload/MS7-12-2_10kg_pdf(1).pdf

  Battery replacement difficulty: Moderate

  OEM: TAIWAN WAN NIEN ELECTRIC APPLIANCE CO., LTD

  Build quality
  Inverter: 4x 200N3LL N-Channel FETs, STMicroElectronics, 30V, 120A. Small heatsinks and battery cables are connected to the board via spade terminals instead of screws, as is the case with all the UPS I have opened so far. The DC Link capacitor is from Aishi, 105C but of small capacity. 1000uF

  There is no MOV at the input, and filtering is done through only one X capacitor. Also, the fuse is 40A, so the maximum that the Inverter can theoretically provide is 480W and not 510W as stated by Powertech. Of course, in reality, the Inverter cannot even provide a constant 280W.

  Overall, many components are missing from the board. In the line protection board, for example, there is only one MOV, while capacitors, diodes, and the other 2 MOVs are missing.

  Conclusion
  It has a good AVR, but I can't say that I am impressed, mainly due to the tragically low duration with a 300W load, where its Inverter struggled, as the power factor constantly dropped, resulting in the active power delivered by the UPS also decreasing. For its price, I would recommend the PowerWalker VI 800 STL, which has better overall performance, its battery lasts longer, and it also has an LCD screen and can be connected to your system via USB, allowing you to control it through software.

  A note about Powertech, say that it is not on the power and you are trying to open a device for a few seconds to do a quick task. The UPS does not open under these conditions if the power it delivers exceeds 140W.

  ADVANTAGES
  • Quite good AVR with voltage boost and drop function where needed
  • 2x Schuko sockets

  DISADVANTAGES
  • At this price, you can find better options
  • Very short duration with 300W load and extremely high losses
  • High power consumption in standby and idle mode
  • Modified Sine Wave output of not so good quality
  • Quite high battery switch time
  • Does not have MOV at the input, so it does not provide protection against overvoltages. Generally, there are many missing input and output filters.
  • I would like thicker cables for connecting to the batteries.
  • It does not have an LCD screen.
  • There is no possibility of connecting to a PC

  Well, except for the fact that the power has gone out three hundred times and the PC hasn't suffered anything thanks to this specific one, my mother has made the same mistake so many times by putting the vacuum cleaner in the UPS, which can't handle so many VA, yet it still lives and reigns.

  A very good choice for live interactive ups, good build quality, quiet and functional. It's worth it, I highly recommend it to you.

  For those who say "I have a PS4, TVs and it doesn't do its job, you simply made a mistake in terms of autonomy in such devices. The machine on my PC (power supply) and some other inductive devices that I have on top do their job wonderfully. And even if the battery lasts for 15 minutes, it is more than enough for saving during a power outage. Before someone comments that it turns off, there is a buzzing sound or I don't know what else, obviously you have put something on it that shouldn't be there. And I wouldn't recommend the PS with the power supply it has, just like a laptop, for example

  I have it for 2 days, I connected it to the TV and PS4, and even though it's plugged in, every 20 minutes it makes a noise like an alarm clock and I have to turn it off to make it stop. In theory, it shouldn't be doing that, so it's not doing its job properly

  What can I say. Pure ps4 in a mess, when the ps4 is supposed to be 300 watts and all that. When the console is in the menu, it doesn't turn off, be careful if you're playing a game. The sixty bucks were wasted.
  And don't show off.. the ps4 pro at full power goes up to 300 watts, on its own (without a TV) and it turns off in game mode. When it's in the main menu of the console, it lifts it up. So it doesn't put the console in full operation. I hope I made myself clear.
  The TV of course does its job properly because we're talking about maximum performance of 200 watts. Beyond that, it's good for all devices to write what each product delivers.

  Very good for its price!!! It's worth it a thousand times. I use it for my desktop computer, and in the game lineage 2 where I played with a power outage, it managed to keep my computer on for 15 minutes with the router connected..!!!

  I have it for a year now without any problem. It holds a 55'' TV for 30+ minutes. Very fast in voltage drops. Makes a little noise. I will buy another one for the camera recorder.

  Quite good for its price.
  I have about 10 of them for the computers of my business.
  And another 2 at 1500VA and 2000VA.
  For the past 3 months that I have them, they have been doing their job properly and I haven't encountered any issues

  I have this UPS for about a year. It effectively protects my PC and my 17" monitor, but it makes a loud noise many times when it's in operation. When it's not making this noise, it makes a sort of whistling sound as if something is broken inside. Therefore, I consider it a mediocre product and I don't recommend someone to easily buy it. Its good point is that it is very easy to connect it to the PC and the monitor. There are also higher quality UPS available in the market.

  Simply excellent and very economical.
  I am an accountant and I use 5 of these.
  In the two years, I have only changed batteries.
  Very good
