USB-C / USB-A Buck-Boost charger 110W "convertiger100" for Berker, without mounting frame

Modern laptops and fast chargers operate at voltages of up to 20V. A standard 12V vehicle electrical system cannot supply this voltage directly.

Standard USB sockets do supply 5V or 9V – but this is not enough for high-power devices. The result in a campervan: an inverter, a power supply unit, and additional losses.

The convertiger 100 solves this problem directly within the DC circuit: the integrated buck-boost converter boosts the on-board voltage from 12V up to 20V as required.

What this means for you:

Direct charging of 100W USB-C laptops in the camper

Higher efficiency (no conversion losses) than when using an inverter

No standby power consumption from the inverter

Less installation work in the vehicle

No distracting light in the camper

The charging voltage is displayed for 20 seconds after plugging in. The display then switches off automatically, with the backlight following after a further 10 seconds.

No distracting light whilst sleeping – no unnecessary energy consumption.

Integration into existing vehicle systems

The convertiger 100 fits into:

Berker Integro

These switch ranges are used by many major motorhome manufacturers and are widely used in professional van conversions. The socket integrates seamlessly – even when retrofitting.

Tip: With our switch range configurator, you can put together complete socket and switch combinations for your conversion.

• 7m 4 mm² 2.5 mm²  

Good to know:

These factors may be responsible for reduced charging performance:

• no corresponding power requirement from the connected device
• charge status of the device
• USB-C cable quality (E-mark required for 5A)
• input voltage too low
• ambient temperature too high

Cable recommendation

For full charging power, use a USB-C to USB-C cable that meets the following criteria:

USB-PD certified with a 5 A / 100 W current rating

as short as possible (ideally under 1 m) and sufficiently thick — cables that are too long or too thin cause voltage drop and may interfere with power negotiation

Compatibility issues may arise with the following cable types due to highly inconsistent implementations on the market:

Magnetic charging adapters and proprietary charging cables (e.g. Apple MagSafe) — here, not all USB-C pins are magnetically connected; the negotiation is emulated by electronics within the cable and thus deviates in part from the USB-PDspecification

Charging cables with an integrated voltage trigger (e.g. in some Starlink configurations), which supply a fixed 20 V to the device instead of negotiating the voltage as normal

Such cables may work, but are not guaranteed to do so. If you encounter problems, please try a standard USB-C cable first.
