I saw the alpenblow and was curious whether it would work for me, but not curious enought to spend €60. So I made my own. It weighs 16g and takes about 3 minutes, 12mAh, and 2 extra breaths to inflate my Nemo tensor regular wide.I saw the alpenblow and was curious whether it would work for me, but not curious enought to spend €60.

Here's the fan I used, others might work as well but make sure to get one with high static pressure.

I removed the top cover of the fan because it's function is replaced by the housing.
Added a backflow arrestor based on u/TheGrandHobo 's suggestion. Not sure whether or how much it actually helps though.
To be honest I'll still just carry my pack liner / pumpsack creation rather than the next gadget to keep track of. I had fun creating it though!
