- Pure sine wave — safe for any device
- Automatic cooling fan
- Includes spare fuses and a set of cables
Voltage inverter, i.e., mobile energy in a pure form
The Qoltec inverter is a pure sine wave, producing current identical to a 230V socket, ensuring safety for all connected devices. It is excellent for power outages and during travel when there is no access to a socket.
When choosing the right inverter, it is worth paying attention to the power value and battery voltage, which must match the inverter's specifications to provide our equipment with the right working conditions. The number of connected devices is also important, e.g., when connecting a laptop and a printer, the power of both devices should be summed. Remember that the power consumption required by the connected device should not exceed 85% of the inverter's nominal power.
Don't lose energy while traveling
The product is perfect as a power source in campers or trailers during family trips. Planning a longer vacation at a campsite or by the lake and looking for a way to connect a laptop or charge a phone on a yacht? It's worth being well-prepared. With the Qoltec inverter, you can power your devices anywhere and enjoy comfort and convenience.
The voltage inverter will be an ideal power source for yacht and boat owners. This smart device allows you to power equipment during long trips away from home, featuring a USB port and sockets to connect electrical devices. You can easily charge your phone, laptop, or connect another device whose power does not exceed the inverter's power. Devices up to 150W, such as smartphones or laptops, can be powered by energy drawn from the cigarette lighter socket during travel. For higher power equipment, we recommend using a battery with parameters compatible with the inverter.
Depending on the power consumed by the device, the inverter can power:
- RTV equipment: TV, game console, music equipment, radio
- Household appliances: refrigerator, freezer
- Office equipment: computers, printers, laptops
- Others: power tools, e.g., drill
The inverter can also be used not only during travel but also as an emergency power source, e.g., to maintain the heating furnace or to power equipment as a UPS during temporary power outages from the grid.
Durable and lightweight housing
The housing is designed from high-quality aluminum resistant to shocks and mechanical damage. It's an ideal choice for people who enjoy long journeys. With the inverter featuring a built-in socket, you can use almost any device requiring a socket connection. The product has a USB port for charging mobile devices and a fan ensuring proper cooling.
Full confidence in the quality of powering your devices
The product is equipped with a range of protections that guarantee full protection for connected devices. Additionally, the set includes a spare fuse to ensure the longest possible operation of the equipment.
The inverter features:
- UVP protection - protects devices from too low output voltage, which affects the stability of connected devices
- SCP protection - this is short-circuit protection
- OVP protection - this is protection against too high output voltage and damage to connected devices
- OCP protection - this is protection against too high current on the line
- OTP protection - this is protection against overheating
