To help me when I have trouble getting enough air.

I use a small electric fan.
But I love to Ebike so I just got me a Flextail Tiny Pump 3x.
They on sale on Amazon for $38. They meant for blowing up air mattresses but I’m using it for blowing air into my face and it works great great. It also has an awesome light for if I was going into the bathroom at night I could bring that with me and have that security of having some air to blow in my face and light up the area at the same time. I’m really happy with it. It’s very tiny just weighing a few ounces.
