How long does the battery last?
The small battery will last 10-15 hours, depending on the use of the bottle. The big battery lasts twice as long.
Is this safe for airplane carry-on?
Both of the batteries meet carry on requirements for all major US airlines, but we always recommend checking with your airline before your flight if you are unsure as airline rules and regulations are at the discretion of each airline and subject to change.
Can you charge the battery with a USB plug?
No, it is charged with an AC Adapter, similar to a computer. The big battery does have USB outputs that give you the ability to charge your phone on-the-go.
How precise of a temperature range does it keep?
Cauldryn Coffee and Mobile 2.0
The temperature average temperature variation of the liquid is only +/-2 degrees once’s it reaches your set temperature. You may notice the readout being a bit lower than that after disconnecting power. it reads a bit lower than that because the temperature sensor is at the bottom of the bottle where there is no vacuum, so the temp at the very bottom drops faster than the whole, and we have to account for that. If you had a thermometer right in the middle you would see it stay +/-2 degrees. That is also why you would notice that it heats up much faster from those lower temps after reaching temperature than if you were heating the whole thing up from cold, it basically just has to heat the bit at the bottom.
Battery Saver Mode will allow the temperature variation to increase to 10 degrees which increases battery life.
Cauldryn Fyre Mobile 1.0
Cauldryn Fyre Mobile 1.0 allows 10 degrees of variation, and operates in the same fashion as Battery Saver Mode on the LCD models.
Do I need to pour out the ground coffee beans before I put on the heating element to brew coffee?
Yes, you will need to empty out the bottle before removing the blender accessory and adding on the heating element.
Is the bottle dishwasher safe?
No, the bottle is handwash only. Do not place in dishwasher.
How does it work?
Models with an LCD Screen - Press the button on the battery to turn it on. When the LCD screen lights up, you can use the up and down arrows to set your desired temperature. Toggling to the optional battery saving mode allows for extended battery life.
Models without an LCD Screen - Make sure the battery is attached and powered on. To boil, add the desired amount of water or ice into the Cauldryn and push the boil (right-hand side) button. To enter temperature maintenance mode, press the maintain button (left-hand side) for one second and the led with flash fast. Press the maintain button again to cycle through the settings.
Blender Model - For best results, fill the unit 50% full and put the lid on. Tip the blender upside down and press the on button twice. Slowly return the Cauldryn blend to the upright position. This will prevent any ice from getting jammed in between the blades and the wall of the bottle. Gently shake while blending.
How long does it take until it reaches boiling?
From ice water, it will be about 18-20 minutes until boiling. From room temperature, it will be about 8-10 minutes.
Does it make drinks cold?
No, it can only heat drinks. Though it is vacuum-insulated so if you put a cold drink in the bottle, it will keep it cold.
How long does it take for a battery to fully charge?
From a dead battery, the small battery will take approximately 2 hours to fully charge. The big battery takes approximately 4 hours to fully charge.
