Great idea. I was so excited when this pump arrived. I tried it today and my experience was a bit disappointing. I first used it to inflate a swim ring that I was trying to inflate with a manual floor pump the other day and only got about 75% because I was just exhausted after 45 minutes of pumping. So I hooked up an electric pump which was fully charged and took about 15 more minutes to fully inflate the ring. I still had my second swim ring in the original packaging and decided to inflate that one as well and measure how long it took from A to Z. It turned out to be about 32 minutes. The pump is very noisy and the output is rather slow. After the second swim ring and about 45 minutes of total pump use, the battery died. I also noticed that the bottom backlight went out at zero, which means the electronic display is already broken. As I said, the idea is good, but the quality should be better. As a suggestion, it would be very helpful for me if the pump had a place for a small charging cable and nozzles in addition to the built-in hose. Or at least take a small bag with you so everything is in one place when you pack it before your bike ride.
