The VLD-950 UPS Line-Interactive 950VA with 2 Schuko Outlets by Power On is a Tower UPS with 2 Schuko outlets. Its operation is (VI) Line-Interactive, which continuously adjusts the output voltage through an automatic voltage regulator, protecting against voltage fluctuations and power outages.

Bought in March '14, it gave up on July '21 with a heavy load during the day, computer, guitar amplifier (100W), stereo. Two battery changes were made during these years, which are reasonable considering their lifespan. Despite being heavy and bulky, it is very reliable, truly quiet, and I highly recommend it as it has saved me many times from power outages and sudden voltage drops, which I have a lot of at home.
Model code: Power On VLD-2000
Type: Line-Interactive
Power: 2000VA
Output waveform: Modified Sine Wave (stepped - simulated)
Dimensions: Large
Weight: 11.9 Kg
Socket style: 4x Schuko
Network & Telephone protection: Yes
Display: Yes, Battery and load levels, AC Voltage In/Out
Connectivity: USB (the corresponding cable is provided as well as an Ethernet)
Price: 185€
Warranty: 2 years. 1 year for the battery
Software: View Power Management compatible with Windows, Mac, and Linux! The manual mentions a CD but you need to download it from the Internet
Standby power consumption: 27.688 W - High
Idle power consumption: 27.887 W - High
Load power consumption (340W): 32.55 W - High
Power factor with load (340W): 0.9715 - Normal
Battery endurance with 340W load: 14:14.50
UPS load level with 340W: 30%
Battery switch time (AC Loss): 14.06 ms
Battery release time (AC Gain): 10.49 ms
Output voltage: 230.36V, very close to ideal (230V)
AVR results: Satisfactory results here. The AVR does not allow voltages to drop below 200.57V and rise above 253.5V. Also, the lowest voltage that the UPS can handle without battery engagement is 169.4V and the highest is 279.5V
Internal fan: Yes (DWPH EFS-06E12M-A005)
Noise (if it has a fan): Low, as it does not operate continuously
Batteries: 2 x 12V/9Ah CSB 33€ each (https://www.batteries.gr/gr/csb-ups12...)
Battery replacement difficulty: Low
Build quality: Quite good capacitors (Jamicon) and good FETs in the Inverter. However, the PCB design is not good and several components are missing.
Epilogue
In general, it is a product that could have been much better with 2-3 changes, a varistor at the input, slightly thicker and shorter cables, and why not, a sinusoidal signal instead of stepped. Not to forget a separate power supply for battery charging and screen operation, so that the main transformer that increases consumption is not constantly in operation, especially in standby and idle situations.
Positives
• Long battery life under load
• Good battery quality
• Good AVR with boost and voltage drop function where needed
• User-friendly software compatible even with Linux
• 4x Schuko sockets
• Low noise (the fan does not operate continuously)
• LCD screen (not very user-friendly though)
• Jamicon DC-Link capacitors
• Quality Mosfets and components in general (but many are missing)
Negatives
• High power consumption in standby and idle mode
• Modified Sine Wave output of not very good quality
• Quite high battery switch time (more than 14ms)
• Does not have MOV at the input, so it does not provide protection against overvoltages
• I would like thicker cables for battery connection
• There is a smell in my sample (I don't know if it will go away quickly)
• Fan that does not inspire great confidence
• Quite large dimensions

I bought it a week ago, but I will return it due to a strong plastic smell in the area. We have been living with open windows for a week in the middle of winter. It has been placed in the space with the recommended distances from objects, as stated by the manufacturer.
I wanted a power stabilizer essentially, and they suggested the one that does both.
I have simultaneously a PC, monitor, speakers, camera, microphone, an 8-input power USB, and a Raspberry Pi.
I noticed that as soon as I connected the power strip to one of the sockets it has, an annoying sound from the speakers stopped. It handles everything together and as soon as I turned off the power, until I shut down the computer and the rest, the time was fine.
Good choice if you want a simple ups.
I have a computer server connected and a 32-inch monitor and I have left it running for about 20-15 minutes until I realize what happened (Power outage) and shut down the computer. A cheap solution for home...
It's worth it!
