Unless you want Anker’s Roav Viva ( on sale right now for just $19.49!), which is basically an Echo Dot built into a car charger, then there’s really only one car charger you should even consider. It’s the AUKEY Flush-Fit Dual-Port USB Car Charger , and it’s on sale right now on Amazon at an all-time low price. This mini car charger is so compact that you’ll actually be able to close the cover on your power port without removing it.
