This is a nice fan and quite powerful for its size. I bought this fan for a cruise because it came with a small night light. I thought it would be great for a cockpit. You can't turn on the fan and light at the same time, which I don't want. But worst of all is the battery life. When the battery is fully charged, the fan only runs for about 45 minutes. I am returning the fan and do not recommend it unless you plan on keeping it plugged in all the time.
