This is really cool with this there is no need for ice anymore, and the fact that it can be charged using solar power makes it more amazing (I love solar powered things).
I really love this type of product because can be used to do more than one thing, this can chill your food or drink and it can also charge the rest of your stuff.
Great Hunt.
Yes, it is a very useful and fascinating article, and the best thing is what you highlight is charged with solar energy!
