If you buy the Acopower Solar Generator (and you should cause it's a great product) you definitely will want to purchase this case. Inside it has foam that is cut out exactly to fit each piece. There is also a mesh pouch for storing the instructions, etc. Outside is nice too and lets you know exactly what's unside. If you're like me and have lots of these black cases for your electronics, you'll appreciate that detail. I wish all cases were like this!
