Does this product automatically adjust the usb charging rate down from 2.4ah for devices that usually need a lower input?

Current ratings for chargers are always maximums - devices will take as much or as little as they need. There is no need to worry about devices that need less current, just plug them in.

Can I make this stop turning off automatically when the power is turned off. It is difficult to reach and a nuisance to have to turn it on each time

that little square button is for on/off switch just turn it on and leave it. mine isn't turning itself off maybe yours is faulty??

Does this have a fuse? My extension cube has stopped working and taking it out from the socket involves moving a heavy table top .

No, but it has a fuse in the plug top. It also has a push button switch on the cube. Have you switched this off by mistake

Is it working with a microwave, a sewing machine, a lamp and a phone at the same time?

As long as you don't exceed the 10 amp (2500 watts) rating, you'll be fine. You need to check your individual appliances to see what wattage they consume. The microwave will be the highest but probably no more than 1000 watts. The others wouldn't use much more than 100 watts each
