[单项选择]The Esky, a great Australian invention—it’s about as important to the Australian household as a BBQ (烧烤的野餐). How else would we move our carefully prepared food and drink around without having it spoilt.
Though it is a regular problem with Esky, you also need to plan. If you haven’t had a freeze pack, then you’ll need to go out and buy a bag of ice (maybe even several bags of ice).
Get a Portable Mini Fridge and you’ll save on the bags of ice as well as a good deal on cleaning time. The Portable Mini Fridge requires a 12V DC supply, and you’ll find this thermo electric cooler the best thing invented since sliced bread (near enough anyway).
One thing this car fridge has over your average Esky—it’ll warm to 60—65℃... and it does all this without any environmental pollution.
Apart from basic cleaning, this thermo electric warmer is largely non-wearing and maintenance-free.
At last, an affordable mini fridge for your car or boat will help save those green vegetables
A. He thinks it’s inferior to Esky.
B. He likes it very much.
C. He thinks it’s like sliced bread.
D. He doesn’t quite like this fridge.
