Trail Addicts: 10 days cold without electricity – The ultimate cooler box in the test
Whatever the multi-day MTB adventure looks like, if you are without electricity for more than 2 days, you will undoubtedly be familiar with this problem: how do you keep your perishables (and beer) really cold? A cool box with electricity is of course a good option, but often you can't run it long enough with the car battery. Starting the engine in the evening doesn't make everyone happy either 😉 An additional battery is possible, but even that doesn't have much power after a day. The big problem with passive coolers is that they simply don't stay cold long enough.
