Immersion Heater, Immersion Water Heater, Portable Water Heater, Heater Element 220V 600W Portable Reheater Travel Kit Great for Heating Boiling Chocolate Coffee Tea Drinking Water

Over the years we have used up several of these on overseas trips. We take our thermal cups to make instant coffee or tea in the room, since few restaurants serve decaf. This one is sturdier than most. Works great and fast on 220v. It's a little slower on 110v, but still gets the job done. Best to use a metal cup and unplug it immediately as soon as the water starts boiling. DO NOT USE WITH A PLASTIC CUP! (We take water from the hotel bathroom faucet, run it through a GRAYL GeoPress Water Purifier Bottle, then use a metal or glass cup for the heater. Never had a bug from the water.)

Useful travel item thats now always in my bag.

The description says it is 600 W. I tested it with a Killawatt and it draws only about 150W. I guess this is the same kind of device that is sold as 300W but it draws that much power only with 220V. When you plug it into 110V (half voltage) you get 150W (half wattage).It seems to work fine. If all you care about is bringing a cup of water to boil and don’t mind waiting 5-10 mins, by all means, this is a good device. If you really care about the 600W power, look elsewhere.

The quality is fine but this heater is dual voltage, meaning it will work with an American 120 volt socket or a European 240 volt, but you'll need a simple adapter (not converter) depending on what country you are going to. The only reason I didn't give it 5 stars is because on 120 volt US electricity, it takes a LONG time to boil a cup of water.

I bought two of these, and they work great..They take about 5 mins to boil a cup of water.These are highly portable and take up very little space in your bag.Very easy to use, make sure you add enough water to cover the element.TIP: use bottled water and you don't need to boil it and will save time.Great for the price,

Inaccurate product details. When purchased, this immersion heater only used half the power it claimed. Couldn't get the water anywhere near boiling. Maybe lukewarm after a long wait. Not sure if it will burn you, never got that hot.

Bought this for my mom to make coffee in her room in the morning. She is in assisted living and can now enjoy a cup of coffee before getting dressed and leaving her room.

These immersion heaters have been around for decades and I always meant to buy one. I finally had a real need when my MD gave me a solution to clear my sinuses and the water had to be warm (not tap water, but distilled water) and my bathroom is upstairs.Now, no running downstairs to fill a glass, nuke it, and take it back up stairs. This immersion heater is Stainless Steel so it doesn't corrode and you and use it in a coffee cup, or a glass, or anything where you need warm pure water. Of course, I'm certain there are many "mad scientists" out there that have other uses in the "lab," but for about 11 bucks, this is a must for my bathroom "lab!!"
