UPS POWERWALKER VI 2200 STL 2200VA Line Interactive

POWERWALKER VI 2200 STL is a line-interactive UPS of medium class, aimed at protecting several important devices – PC, NAS, router, small server, or workstation. With a capacity of 2200VA and 4x CEE 7/3 (Type F) Schuko outputs, you have enough reserve for all the main equipment around the desk or in a small office. The line-interactive type provides voltage stabilization during fluctuations in the network, without switching to a more expensive online class. The LCD display helps you monitor the status in real-time, without guessing what is happening with the battery and load.

What you get

Inside, there are 2 batteries 12V/9Ah that provide about 3.9 minutes of runtime at 50% load – completely sufficient for controlled shutdown of machines, saving work, and safely turning off systems. The output voltage waveform is a simulated sine wave, which is fine for most PC PSUs, network equipment, and peripherals. It supports input voltage 162–290 VAC, so it easily handles typical drops and spikes in home and office networks. Through a USB connection and the PowerMaster software, you can monitor load, charge, and set up automatic shutdown of computers. Full charging to 90% in about 8 hours means that after a night without power or a series of outages, the next day the UPS is ready again.

• Line-interactive type with a capacity of 2200VA, suitable for protecting several devices simultaneously – PC, NAS, router, small server.
• 4x CEE 7/3 (Type F) Schuko outputs for direct connection of standard plugs without the need for adapters or extensions.
• Uses 2 batteries 12V/9Ah, providing about 3.9 minutes of operation at 50% load for safe data preservation and controlled shutdown.
• Wide range of input voltage 162–290 VAC and surge protection, which protects the equipment in an unstable network.
• Simulated sine wave output – a good solution for standard computer power supplies, monitors, and network equipment.
• LCD control panel for quick status check – charge, load, operating mode, and alarms without opening software.
• USB connectivity and PowerMaster software for monitoring and automatic shutdown of connected machines.
• Charging time about 8 hours to 90%, which is convenient for overnight recovery after a long power outage.
• Weight of 10.8 kg, making it stable enough under the desk or next to a cabinet, without easily moving when pulling cables.
• No option to add additional batteries, so plan the runtime according to the factory capacity.

Who it is suitable for

This UPS is a good choice for a home office, small business, or gaming/work PC, where the most important thing is not to lose data and to avoid sudden shutdowns. It is suitable for several machines plus network equipment, but it is not a solution for long autonomous power supply or heavy server rack configurations. If you are looking for hours of battery operation, not minutes for safe shutdown, you will need a different system.

The most sensible thing here is the combination of 2200VA capacity, convenient LCD panel, and control via USB/PowerMaster, which gives you real control over the power supply without entering more expensive UPS classes.
