Hi, I've just seen your video and wondered what setting you have the freezer box on when you say the powerbank could keep it cool for up to 50 hours? I run a coffee van selling ice cream but I need something to keep it frozen overnight when it's not plugged into the mains. No cool boxes I've tried, work as yet so I'm looking for a battery powered box like this.
