Travel voltage converter for sensitive devices

The BFKK 500/350W adapter steps down 100-240V input to 110V 60Hz output using 100% pure sine wave technology. It supports heating tools up to 500W and electronics up to 350W, making it suitable for CPAP machines, medical nebulisers and other sensitive equipment that requires clean, stable power.

Sustained load protection with automatic recovery

A silent cooling fan manages heat during continuous operation while a touch switch controls power state. When overheating or overloading is detected, the unit blinks and cuts power automatically, then restarts once conditions return to normal without user intervention. This protects both the converter and connected devices during extended use.

Replaces separate transformer and USB chargers

Seven devices charge simultaneously through three US AC sockets, two PD 20W ports and two QC 18W USB-A ports, removing the need for multiple travel adapters. The kit includes a detachable EU cord and UK, US, AU, IT plug heads for use in over 190 countries. Travellers needing only USB-C laptop charging above 20W or high-wattage appliances beyond 500W should consider dedicated solutions.
