I absolutely am in love with this charger! it works perfectly, as well as larger ones but this one is actually about half the size of the one that I already had. It's compact which makes it absolutely perfect for putting in a purse, or putting in your glove box, or even sliding it into a suitcase to go on a trip. it's just so nice to have something that's just as powerful as the larger version but way more portable, a fantastic buy!
