Took the KA 75ltr duel zone fridge for a weekend away off grid. The fridge worked extremely well, plugged into solar charged KA battery box and maintained solid charge. The fridge ran 24/7 and maintained temperature. Only one small issue is that when the compressor automatically switched off the temp went up several degrees (+5) before it switched on again. Apparantly this is normal as stated by KA but only + or - 3 degrees. The fridge cooled down again quite quickly and ran quietly & efficiently. The anderson plug at the side was the winner for me. Would definately reccommend to anyone wanting a solid well built fridge.
