I just got back into town on a flight and the inhale in with the nose did work better in the airport. Not sure why it does but it did. Interesting.
I recently found a Samsung cell manufacturer (re-brand) that makes a 9V Li-ion that does NOT explode!!
It has a very large capacity and a very high discharge rate for power-hungry applications.
And yes, you read that correctly....A LI-ION CELL!!
I love to own a puck but I am not a modder. I saw this Double Capacity MintyBoost with 4-AA Battery Holder Modification but it only outputs 500ma . How easy to change it to 3A or 5A and what parts I need? Thanks
