The iPhone 8 is all cracked up. I was unable to get it to come on. The iphone 7 charges and is in great condition but it has an icloud activation lock on it. I don't know much about the Macbook or the Macbook Air. I don't have the power cables so I was unable to test them. I assume they are not working.
All these are listed for parts or not working. Please know that you will have these repaired prior to using or reselling.
