Camping Cool Boxes
What's a Passive Coolbox?
A Passive Coolbox is the only type that used to exist before the plug in ones were invented. It's a solid case coolbox which you need to pack with your food and drink and a few ice packs and head off to the campsite or the beach, Some passive coolboxes these days will guarantee to keep ice for up to 5 days so they are great if you are wild camping or have no hook up at the campsite.
