## Questions & Answers

**Q: This thing is BIG 3.75 dia. how does this thing fit in the car cup holder?**
A: The battery or car charger both fit.  Without those it wont.

**Q: How do I clean the Cauldryn?**
A: The top and bottom come off making it easy to clean. The cup is stainless steel and cleans well.
Some parts must be hand washed.

**Q: Can you detach the base and still keep coffee at the target temp for 2 hours? Or do you have to have the base attached for the heater to work?**
A: Not sure if the cup will hold it's temp for 2 hrs. without one of the 2 power  power bases that came with my cup attached.
My cup came with the A/C powered base you could use at an available outlet or a battery powered base for off grid use.
The cup itself has a bottom that is removable, the heating element is part of the bottom with a docking style plug that connect to the power bases.
Oh and my 16 oz. of coffee never to be  left alone for 2 hrs. that 's why I'm not sure about how long the temp will stay at target without a power base attached.

    Hot (not warm) coffee, happy buyer!
  

*by J***D on Reviewed in the United States on December 11, 2019*

I commute every morning 45 minutes to work.  Invariably my coffee is lukewarm before I arrive.  This product was recommended to me by a friend  and I am finished using other coffee cups and yeti style mugs. Not only does this device keep my coffee hot for the drive, it actually heats it to make it hot throughout the day.The assembly is foolproof  and the function is straight forward.  I downloaded the app and it has made  using this device as simple as it can possibly be.I’m excited to purchase the mixer type attachment and use this device on my next outdoor camping adventure as this baby will boil water in minutes!!! Happy with my purchase and happy to be drinking hot, not warm coffee all day long.

    Awesome concept, a little pricey
  

*by S***N on Reviewed in the United States on December 15, 2019*

I received this item as a gift. It's really nice! But as others have noted, it's bulky and a bit cumbersome. I appreciated the added base to plug in and keep the drink hot without the battery pack - that comes in handy at work. The ability to boil water, in a mug, is stellar. However, the cup itself is only 16 oz. That's not a lot of water but is sufficient for most dehydrated meals (I take it car camping; it's FAR too heavy for backpacking). And it heats the water fast, too! I'm eager to get the blender and percolator attachments! Overall, it's a good item but a little pricey for me. The 2 usb chargers can be handy in a pinch, too.Overall, I recommend this product.

    Bulky but it gets the job done.
  

*by C***. on Reviewed in the United States on December 13, 2019*

Bulky but battery last quite long. It heats up water from 15 to 55 degree celcius in about 10 to 15 minutes. Battery fully charged can heat uo water like this abt 4 to 5 times. It takes 3-4 hours to charge the battery. Same cable is used for the battery base and charging base so can't use them at the same time. Lid seals quite well. The remote app works but not friendly to use. Price similar like Ember but the build is not as quality. However, it lasts much longer. I like to attach the battery base for heating and remove after it is heated. This way the cup is easier and lighter to travel. But if u need the water constantly at a temperature..expect it will be like carrying a light laptop around. Battery is almost too big for TSA so be careful if u carry it on an airplane with other big battery pack for phone plus a laptoo ..u may be over the limit and it's up to ur luck if you don't get caught.
