Review on 🔌 Cllena Triple Function Car Charger with LED Voltmeter & 12V Outlet: Power Up Your Digital Devices with Style (Blue LED) by Justin Ewing

I mounted this into the top of a battery box for my 12v deep-cycle battery I keep on a trickle charger in my shop for various uses during a power outage. Now, at a glance, I can see the existing charge on the battery and have the convenience of the 12v receptacle and the usb ports as well. It's a good-looking and well made item.
