Cooling Fan for iPad

But now and then the iPad overheated and had to be shut down. This happened often toward the end of a long trip. In each such case, the forced shutdown was really annoying: No longer could we see ADS-B information about nearby aircraft and couldn't navigate precisely under tight airspace conditions. Not good.
