Bring the charging power of a wall outlet to a place where there are no walls with the BioLite KettleCharge Battery. Ready day or night as long as you have water, the KettleCharge is compatible with a variety of heat sources, including gas ranges, backpacking stoves, the BioLite CampStove, or any concentrated flame. It produces ten watts of power that charges phones, tablets, or any other device you might need juiced via a USB port. All you need to do is add water to the stainless steel kettle, bring it to a boil, and the electricity produced gets sent to the Power Handle, leaving you with potable water and 10W of usable power. The smart LED interface monitors the strength of your heat source while providing real time feedback on how much electricity you've generated and the USB extender keeps your devices out of harm's way from the heat.
