I have been using this product for over a year now. It works fine in my Buick Enclave. I've been on many long trips and only had this to charge my Surface Pro 3. It constantly charges the system and does not cause blown fuses or other problems in the car. I usually plug my Surface into the charger when I start driving in the morning and by midday it's fully charged, even though I drained the Surface's battery the night before. I love that I can unplug the cable when not in use and that it has a USB socket so I can charge my phone while traveling. Great product and thanks to Kingdo for providing it.
