These days, Samsung equips its latest models with Adaptive Fast Charging. This technology allows you to charge your smartphone much faster. One disadvantage of this technology though, is that your charger must support it. Luckily Samsung offers a solution with this special car charger. Note! If your smartphone doesn't support this technology, the charger's no good to you. Always make sure you check your phone in advance! This car charger features two USB ports, so you won't have to choose which device you want to charge first.
