Converter needed in Dubai & India?

[mylescool]

I have a CPAP made in US. 24 V. I have adapter plugs but do I need a voltage converter for Dubai and India?

No or maybe. What is written on the machine?

[D.H.]

Most (all?) CPAP machines are dual-voltage. However, you need to see what it says on you machine to be certain. If your machine has a "brick" (a big block in the middle of the power-cord that looks like a brick), it will be on that. If not, it will be on the bottom or side of your machine.

Power in both India and Dubai is 230 volts 50 hertz. U.S. power is 120 volts 60 hertz. That will most likely be a non-issue. What will be an issue is the shape of the electric sockets (also called "power points"). Please follow the link below to see what you'll need in any country. Also, I pack three normal size extension cords, rather than one long one; I find it more convenient. Note also that since there's a U.K. influence in both these places, what we call an extension cord might be known as an "extension lead." Beware of the "M" type socket as the "universal" adapters won't fit into it.

Here's the last caveat. Most power strips that are sold in the U.S. are also surge suppressors and won't work on a 230 volt system.

I've been to Dubai and all I needed was a standard US to EU converter.

Depending on where you will be in India, you may need an automatic voltage regulator. Power voltage is not consistent in most developing countries with massive spikes and much lower than advertised during peak usage (brownouts) so you can not be assured that it will be 230 volts at all times. AVRs smooth out the voltage so it stays in a tight range. If it spikes, it will try to offload the current or will shut off if it can't so that your equipment is not fried. If it goes too low, it will keep it above some predetermined range so that brownouts won't affect your equipment. You can usually pick one up for $50 to $100 US. The nice thing about them is that they typically have at least 1 plug that is 110 volts so that your US devices if they don't have a voltage range. You still need to check the hertz on your appliances since the US is 60 hertz and most of the rest of the world is 50 hertz. If your appliance is not rated for 50 hertz it will not be safe to use even if you have 110V power.
