I have been "plugged in" since 1991. My current CPAP machine is a Transcend mini-cpap; about the size of a 12 oz soda can, and weights about a pound ( the separate humidifier is a bit bigger ). It comes with worldwide adapter plugs - you use a different one on the French side, and automatically adapts to whatever voltage is provided. No need for a separate transformer..
I take it everywhere that I travel. When I go to Saint Martin, I also take an 8 hour rechargeable Lithium - ion battery - just in case you have a power outage. I purchased the battery about 3 years ago - I think that I paid about $250.
If you have any kind of medical insurance, they will likely provide you with a heavier older model CPAP machine that is much too heavy to lug around. I returned the last CPAP sent by my insurance company. I purchased the Transcend on line for less than $500.
Don't leave home without it -guarantees a good nights sleep.
