Tiny flush-fit dual USB adapter for cars

I've been using Aukey's Flush Fit Dual Port USB adapter since early 2016. Once you push it into the car's "cigarette lighter" hole, it's close to a flush fit. It could be a chore to pull it out, but I've never had a reason to. It's regularly $9 but if you use the Amazon code AUKECAR7 it costs $7.
