I guess your Macbook Air port is Type-C port, there are following ways for you: Way 1: need a USB A to USB C adapter. If your computer is type-c port, you need to have a USB A to USB C adapter, use the equipped usb cable, type-C end of USB cable to connect the camera, another end of USB Cable (usb-A) to connect the USB A to USB C adapter, and then insert into your computer, you will see a U disk icon on your computer, and then you can transfer the phones and videos on your computer. Way 2: Need a usb c sd card reader for Micro SD/SDXC/SDHC. We hope it is helpful to you. Thanks for your kind asking 

Hello, thank you for your question, you can charge your laptop, the premise is that the solar panel must be placed in the sun to charge, it works: in the sunlight to collect ultraviolet light to convert into electricity, thank you 

Yes, there is a seperate pocket for a 15.6" laptop. 

Of course it can be used. But since slides are made of glass, our microscope is equipped with 8 LED lights that reflect light during use.
