See Battery Guide for more details.

To guarantee compatibility, use the cable included with EcoSimmer.

If an alternative USB-C cable does not support power transfer of 100W or more, EcoSimmer may not function properly. EcoSimmer 100 requires 100. Not all USB-C cables are made the same, so please ensure that the USB-C cable included with EcoSimmer is being utilized to guarantee that a compatible cable is being used. Some USB-C cables support data transfer, some support power transfer, and some support both. Any cable rated below 100W of power transfer (such as 30 W, 45 W, or 60 W) will not work with EcoSimmer.

No, EcoSimmer does not come with a battery unless you buy a bundle. To pick the perfect one, check out our Battery Guide.

EcoSimmer does ship with a compatible USB-C cable.

Turn ON: Simply plug EcoSimmer into a compatible 100W USB-C power source. It will automatically turn on and begin heating.  

Turn OFF: EcoSimmer automatically stops heating and turns off when:
- Unplugged from a power source
- A boil is detected
- No contents are detected

When turned on, EcoSimmer will display two numbers. Read them vertically as the temperature of its contents in Celsius. For example: when EcoSimmer displays “93”, its contents are at 93ᵒC (199ᵒF).

Bonus: Generally, the numbers in Celsius can be interpreted as the % progress towards boiling as well.

When a boil is reached, the numbers flash rapidly, indicating that heating has stopped. EcoSimmer will continue to flash until unplugged.

To use the Original EcoSimmer 100 in the outdoors, you need 3 things:
1) EcoSimmer
2) USB-C cable that supports 100W (included with EcoSimmer)
3) 100W power source (sold separately, please see Battery Guide)

You do not need any pots, pans, lighters, or gas canisters!

Pro Tip: Bring a water filter.

Save battery energy and shave minutes off cooking time - use already purified water. EcoSimmer can boil water to purify it so no worries if you don’t have one.

Hand-wash only.  

Wash EcoSimmer thoroughly before first use and after every use. Hand-wash using a cloth with warm, soapy water. Use mild soap and avoid cleaners containing bleach, chlorine, and abrasive or other harsh chemicals. Use extra caution when cleaning near the EcoSimmer USB-C port and do not let water come in contact with the USB-C port. The lid can be washed on the top rack of the dishwasher.

Yes! EcoSimmer is safe, durable, and eco-friendly. It has been tested and certified to UL and CSA 60335-1 by SGS.
See User Manual for additional safety considerations.

There are no dynamic settings to change the cooking speed of EcoSimmer, however there are several ways you can get hot food or drinks faster:

1) Try coffee temp – if your water is already purified and don’t require a boil, try heating to a lower temperature.

2) Keep the lid on – to reduce heat waste and to ensure all heat goes towards warming up your food or drinks.

3) Use only as much water needed, no more – water will heat linearly, so removing half the water will halve the heating time and energy drain on your battery.

4) Start with warmer water – try starting with warmer water to reduce the temperature differential to coffee temp or to boiling temp.

As well, shave minutes off your cooking time by brining water to a coffee temp or to a simmer, not all the way to a boil.
