Description
Convert your US, Canadian, or Mexican 120V power supply to 100V with the UMI 1800 Watt voltage converter, engineered specifically for Japan appliances. This heavy-duty step-down transformer features a compact toroidal design measuring 7 x 18.5 x 24 cm and weighing just 4.1 kg, making it both space-efficient and portable. Multi-layer protection keeps your appliances safe with surge protection to prevent circuit breaker trips, overload protection with alarm function, short circuit protection, and overheating safeguards. The toroidal transformer uses heat-resistant insulation rated above 900 degrees for long-term reliability. Dual outlets let you power two Japan-rated devices simultaneously, whilst the CE and CQC certifications confirm compliance with safety standards. Ideal for travellers, expats, and anyone relocating Japanese electronics abroad, this converter delivers consistent 100V output from standard North American electrical outlets with a reassuring 3-year warranty.

Key Features

The UMI 1800 Watt converter steps down 120V AC power to 100V, matching the voltage required for Japan appliances used in US, Canada and Mexico.

Surge protection prevents circuit breaker trips and fuse damage by shielding your home electrical system from voltage spikes.

Dual outlets allow you to connect and operate two Japan-rated appliances at the same time from a single UMI converter unit.

Compact toroidal transformer design measures 7 x 18.5 x 24 cm and weighs 4.1 kg, offering slim profile and lightweight portability without sacrificing power capacity.

Heat-resistant insulation material rated above 900 degrees ensures the UMI transformer maintains safety and efficiency during extended use.

CE and CQC certifications confirm the voltage converter meets rigorous electrical safety and quality standards for international use.

Overload protection with audible alarm alerts you when the 1800 Watt capacity is exceeded, preventing damage to connected appliances.
