>>467579>It powers a fan too?Yes, but according to the reviews, the blower / power pack component needs to be plugged in at home to charge up the internal Li-on battery prior to its first use but once there's a fire going, the fire keeps the fan blowing and charges the battery and whatever is hooked up to the USB port (2w continuous / 4w peak).
There is also a high / low blower fan speed switch; low speed being initially used when starting the fire, then switching to high speed for cooking and afterward, back to low speed to burn less wood as a kinda mini-campfire. Though reviews also mention after about 1-1/2 hours, the ash has to be dumped out and the fire restarted (though I suppose some of the still hot coals and burning sticks could be used to speed things up).
