This is not really good for heavy duty inflation...

I used this pump 3 times to blow up a shallow inflatable pool. The attachment fit perfectly. The first two times, it got the pool filled with air with no issues. The 3rd time I hooked it up to inflate the pool, it just died. I thought maybe it just needed to cool off because it was pretty warm when I picked it up. There was plenty of ventilation around it, so it wasn't being smothered. I let it cool off and tried it again, and it just doesn't work. Back to the old fashioned manual pump I go....
