Review on 🔌 [2021 Upgraded] Qidoe Aluminum Metal Dual USB Socket with LED Voltmeter & ON/Off Switch – Quick Charge 3.0, 12V/24V USB Outlet for Car Boat Marine ATV Bus Truck and More by Isaac Morales

Generally does what it's supposed to. The voltage indicator is clearly visible. The on/off switch cuts power to the entire device, which is nice when you don't have to unplug anything. My only complaint is that the lid doesn't hold up very well. It opens a minuet or so after closing. Edit: I found that only one of the USB ports actually works. I'm sticking with just using the connector above the voltage indicator. Also, the thing seems to be durable.
