A voltage converter is a practical solution that allows you to convert 12V DC to 230V AC. This allows you to power electrical devices wherever there is no access to the mains – in a car, camper van, at your allotment or whilst working on the move. The device generates a modified sine wave (MS Wave), which ensures stable operation of many popular electronic devices.
Modified sine wave – simple design, lower failure rate
The ideal choice for everyday use
Devices that do not require a pure sine wave, such as LED power supplies, LED lighting, computers, laptops and small household appliances, will operate without any problems with a modified sine wave inverter, which produces an output sine wave with an approximate AC voltage waveform, the RMS value of which is the same as that of a sine wave found in the mains supply. This type of inverter is characterised primarily by lower failure rates and a simple design.
Compatibility with modern and traditional batteries
Compatibility with AGM, GEL and LiFePO4 batteries
The voltage converter has been designed to work with common types of 12V batteries, making it suitable for a wide range of power supply systems – from automotive installations to off-grid systems.
Match the battery to the inverter’s power rating
To ensure correct operation, the battery should supply a voltage within the range of approx. 10.5V – 15.5V DC and sufficient current to power the connected devices.
- the higher the inverter power, the greater the current demand
- the recommended minimum battery capacity ensures stable operation
- higher capacity = longer operating time for devices
Ensure your devices have the right operating conditions
Choose the right power rating, match the voltage, allow for a safety margin
When selecting the right power converter, it is worth paying attention to the power rating and voltage of the battery, which must match those specified on the converter to ensure our equipment operates under the right conditions. The number of connected devices is also important; for example, when connecting a laptop and a printer, the power of both devices must be added together. Remember that the power consumption of the connected device should not exceed 85% of the converter’s rated power.
Why is this so important?
✔ prevents overloads
✔ extends the device’s lifespan
✔ ensures a stable voltage for the connected equipment
✔ minimises the risk of shutdowns and performance drops
Don’t waste your energy whilst travelling
Freedom wherever you are
This product is ideal as a power source for motorhomes or caravans on family trips. Are you planning a longer holiday at a campsite or by a lake, and looking for a way to plug in your laptop or charge your phone on a yacht? Thanks to the Qoltec inverter, you’ll be able to power your devices anywhere and enjoy convenience and comfort. The voltage converter will be the ideal power source for yacht and boat owners. This smart device will allow you to power your equipment during long trips away from home; it features a USB port, a USB-C port and mains sockets to which you can connect electrical devices. You can easily charge your phone, laptop or connect any other device whose power consumption does not exceed the converter’s capacity.
Depending on the power consumption of the device, the power supply can power:
Audio-visual equipment: TVs, games consoles, music systems, radios, smartphones, routers
Office equipment: computers, printers, laptops.
Emergency power supply at home
The inverter can also be used not only when travelling, but also as an emergency power source, for example to maintain power to audio-visual equipment as a UPS during a temporary power cut. This device gives you energy independence and the ability to use electronic devices in all conditions – both whilst travelling and in emergency situations.

Remember to connect the wires and ensure the correct polarity of the power supply voltage!
Batteries must supply a voltage within the range of 10.5V to 15.5V DC (for 12V converters) and be capable of providing the current required to power the connected load. To estimate the approximate current (in amperes) that the battery must supply, simply divide the power of the load by 10. |
