Two For The Price Of One
When you buy a charger that claims to have a USB port the next time, make an effort to check and see if it actually has one. The fact that this device has two USB ports might seem like an advantage to some people, but the manufacturer disagrees with that assessment.
They were able to conceal the second port, which leads us to wonder whether it would have been more cost-effective for them to simply manufacture two ports and conceal one of them. Since they were likely to succeed in doing so, however, we are left to wonder whether they were.
