Review on Portable Battery Operated Fan: Small Table Fan with Powerful Airflow and Quiet Operation for Home, Office, Bedroom, Desktop – Adjustable Speed Head, Mini Personal Fan (4 Inch) by Carlos Whitfield

So far I am satisfied with this fan. I actually use it to cool my MacBook which gets very hot when running certain programs. A cool breeze from above works better than a cooling pad from below. This fan does exactly what I need. However, there are a few things I don't like about it. So. Pros: - Long battery life. I mostly use it on low setting, but even with prolonged use on medium to high setting I get several hours of battery life. More time on the low. Nice and compact, doesn't take up space on my desk. Powerful. This tiny thing can really release some air, even on the lowest settings. Cons: - Not as quiet as I had hoped. It's not very loud, but definitely not what I would call a silent fan. Charging takes a long time. It can be used while it's charging, but I've found that it uses less energy in this case. You have to switch speeds with the power button. If you choose the wrong speed, you'll have to scroll through all the others, turn them off and on again, and then scroll again to get to the speed you want. This is very annoying.
