Hi Dryer
The TEG (the batt/fan part) is now dead...
At the start it did all the right things.
As you might have noticed in the video it takes a little while for the green light (USB out ready) to come up but once up it did not work.
The next day I let it run for about 20 minutes after the green light came up before plugging a USB device in . (I had re-charged the battery via PC USB in the meantime)
Still nothing.
Two days later the fan stopped working and if I plug it in on the PC USB I get a green light no fan going.
So now I am waiting to hear from BioLite.
Kind of funny that having posted about this product in various forums I am the one to get a faulty one...
