Having been born before the advent of computers, I am at a disadvantage in terms of upkeep and maintenance for my personal computer. The first experience of a serious nature with a computer was with a computer the size of a small house. It executed the exact functions the calculator in your mobile phone does - less, actually.
Look wise it is very sleek and looks like a mini version of the normal sized fridge. It uses USB power of 5 volts and the temperature of its cooling pad decrease after five minutes of use to 8.5 degrees. It is mini sized having a dimension of 19.4 x 9 x 9 and weighs only 362 grams. It is a great portable device which can be used to great effect especially when one's working on ones computer. It can also be used very efficiently when one is travelling to keep their beverages cool and it does not require any drivers to be installed before it can be charged, one simply needs to just plug it in to charge it. The USB fridge although portable and handy cannot match the cooling of normal fridges and therefore how long they will prove to be effective is uncertain.
