Of course I also thought about the purchase of a compressor cooler. The work more efficiently and use less power. For compressor coolers are of this size considerably heavier and more expensive!
So I eventually bought Dometic RC 2200 EGP CombiCool. The box came in the package of the manufacturer and therefore fully protected sufficiently. For delivery, I could not detect any damage. So unpacked and only time connected to 230 volts and filled with drinks. Major large bottles fit standing in the box. Only the "narrow" and high 1,5 l bottles are too high. 20 or 24 bottles of beer (0,5 or 0,33 bottles) fit easily inside.
I put the box on the balcony and the drinks were very fast cooling, so that I have the power of max. So could reduce level 7 to level 3. The box cools properly!
Even the first test in gas mode, it has survived. After pre-cooling at the highest flame the average position for a cool drink just fine!
Here was already written that the lid of the cool box has no gasket. Which is not required! Inside the cover there is a continuous raised that closes perfectly with the box. That's enough poetry! By design, the cold stays where it should be - in the box!
The processing is for the price perfectly fine! The material makes a stable impression. The plastic components are sufficiently strong and the aluminum body of the box makes them look very high. The weight of the box is 14 kg in the green zone. The box is well filled but very quickly extremely difficult. The two side handles allow a good wearing, but rather only when empty! When filled box to a Trolli for transporting recommends.
I will continue to use the box at home as an additional cooling facility for drinks and even when camping and would buy again at any time.
