We have an Icey-Tek, bought a few years ago and it's totally amazing.” (Reviewed by northerngirl2012) Our verdict Whilst cool bags are certainly the most portable, if you want to guarantee a cool drink for longer, it may be time to upgrade to the best cool box. Although relatively big and bulky, these robust and highly-insulated cooling boxes can house significant capacity and chill your contents for a number of days rather than hours.

You either plug the box into your car (12V), the most common type of charger, or into the mains by a UK plug. They require constant power, though will still keep contents cool for a few hours if you unplug. You can get battery-powered boxes, but they’re less common and far more expensive.
