I of course love this thing because of the size. But it also holds the charge of the battery for a pretty decent time. I was recently on a motorcycle road trip and of course I took this. My battery jump starter and other small things to fit on my bike. When we arrive to our Airbnb, I noticed my air pressure was low. This very lightweight air pump pressurize all of our tires in the group within about 20 minutes. Although I think you are supposed to have a break in between, it didn't take long and it only took the battery level down one notch, which was plenty enough time for us to finish the entire road trip. Make it back home before charging again where I definitely did not have to. Small enough to fit under my seats but I put it in my saddle bag. Since my trip I have used this to inflate A backyard swimming pool. The future that turns off once it hit your selected PSI makes it wonderful so you can set it and walk away (although it's not recommended), But in the winter time if it is freezing you can use this sit in the car or in the house. Let it do its thing. Come back and you will be good to go. Highly recommend.
