It is great to charge in the car. I take my Kindle everywhere, so the battery doesn't last long. This is a nice kit with a leather cover. It is essential to all Kindle users. I've used the USB cable with other items as well. It comes in handy. Battery Life Mine burns out fast, so I really need these chargers. Display/Screen Quality The screen covers are wonderful. Ease of Use It is nice to have a variety of chargers. You never know when you will need them. I've used the car one probably the most. I find myself on the way to a doctors appointment, and I realize my Kindle battery is low. It charges pretty fast. Durability All items seem very sturdy. Design I like the entire package. It has everything a Kindle user would require for charging and upkeep.
