Still getting rid of extra stuff that I don't use... The Peltier generator in this BioLite does not work. Possibly a faulty battery (LiIon) . The stove itself is similar to other gasifying stoves , the Peltier unit apart from having a built in power generator (USB out) has a fan for the stove. One could add a battery operated computer fan , similar to the Sierra Stove. I have taken apart that orange box but I am no good at all with electronics. The burner is 545g.
