    Not happy.

    Bought one and the USB-C port didn’t work. Returned it to Best Buy and got another one. Same thing: USB-C doesn’t work. And this one also has a bad connection on the wiring harness for 12v cigarette lighter outlet. Power to unit cuts out unless the wire is positioned just right at the plug. Have to repeatedly bend the wire to the side of the connector to get power to the unit. As for the USB-C, there is nothing wrong with the cable(s) I used. They work just fine with other devices. I just purchased another different brand from Best Buy and everything on it works like it’s supposed to, including USB-C. I’ll be returning this Cobra to Best Buy also and getting a refund.

    No, I would not recommend this to a friend

    Does the job. The cigarette lighter plug didn’t fit really well. Plus it cracked after unplugging the second time. After that happened I wired it directly to the battery with an inline fuse and haven’t had any problems.
