🔋 Cllena Dual USB Charger with Voltmeter, 12V Power Outlet, and Toggle Switch - Multi-Functional Panel for Car Boat Marine RV Truck Camper Vehicles GPS Mobiles (Green) Review

All components work well, the bezel is a bit unusual in size. It would be nice if they made it to fit in the standard PVC switch box. I left out the bezel and used an electrical PVC cover as I installed it as a free standing outlet on the boat.

Worth the money. Highly recommended! As a John Deere technician, I like to turn on the voltmeter from time to time because I know the regulator is putting out a charge. For me, this is the best thing about this product. USB charging is an added bonus.

My only suggestion to the company would be to have fork swap options. (i.e. two plugs instead of one plug and one USB port.) I could use two plugs.

While all gadgets work. USB charges my iPhones. The 12 volt outlet works well. The voltage reading is fairly accurate compared to my multimeter readings. You can see the gauge reading in daylight. I've seen a lot of confusing information on how to wire it up, but I just followed the diagram and it worked the first time. The on/off switch has three pins. The mean is positive from the source. Copper color - negative return to source. The rest goes to the next caliber. Exactly as shown in the…

I didn't install most of this panel but I put the voltmeter in the car in the hole where the cigarette lighter used to be and connected it to a constant +12V Power supply so it was on all the time. I've found it only draws 8mA so I don't have to worry about battery drain. (car clock draws 4mA) So far this has saved me twice. The first time I broke the generator bracket and lost the charge. The voltmeter dropped from the usual 13.8 to 12.1 volts, which I noticed immediately. The second time the…
