Both power supplies are designed for universal inputs of 100-240V, 50-60Hz and can be used in most countries around the world.
This S9 90-Watt Power Supply measures approximately 6.5 x 2.5 x 1.5 inches and weighs approximately 1.25lbs. It is designed to power both the S9 CPAP/VPAP and an H5i Heated Humidifier. It can also be used to recharge ResMed Power Station II Batteries.
