Upgraded 4 in 1 Charger Outlet Socket Panel, Dual QC 3.0 12V USB Power Outlet & Car Voltmeter Gauge & Cigarette Lighter Socket &ON Off Rocker Toggle Switch for Car Marine Boat RV Truck (with Wire)

Installation was a breeze, instructions were very easy to follow. I use the 12v outlet for my Bluetooth adapter to my stereo and it works amazingly. The voltmeter is a great bonus as I am able to monitor my bikes battery level as I ride. Would definitely recommend purchasing.

I am building a sound podium for like karaoke and singing in church I needed a way to plug in other devices for power off of a sealed battery. This had everything I needed not only does it have the USB ports but a 12 Volt power port that can use other USB ports or connect "Y" 12 Volt connector that thing could be extended from there. This is perfect and at a reasonable price.

This was just what I needed. I installed this today in place of an old single DIN radio inside my dune buggy. Very simple installation, and like that it comes with an in-line 10A fuse. It is a bit smaller than a single DIN radio head, so if you are replacing one then you'll need to make a bezel to cover the gaps, but that was not a big deal for me. This is a great little USB power panel.

This worked great for my trolling motor 100 AH lead acid battery box build. Everything worked correctly. I am not able to confirm if the USB outlets are putting out 2.1A, but they will charge your device. I deducted 1 star because of wiring diagram confusion. Pay no attention to the gold blades being stated as + Positive. The line in (+ from your power/battery) goes to center blade on switch. The load (+ out of the switch is the silver blade. The gold on the SWITCH is - neg. in from your battery. All other units (volt meter-USB-12V power outlet) are marked +/- which are correct regardless of blade color. I did not use the inline fuse that was included, instead I spliced in a blade type fuse holder...I have made and attached a .jpeg template that I used by taping on my battery box and drilling through that some my find helpful in their install. You should be able to copy/save it and print out full size (4.1" x 3.3". I hope this review is able to help in making a purchase decision.

The ready to go wiring harness really made install simple and easy.

Revised: The fuse while not blown had a weak enough connection inside to prevent the Voltmeter from coming on. An Ohm meter shows the fuse good, the 12 volt outlet and USB plugs lit up, but the voltage must have been too low for the meter (even though the battery is fully charged). The meter would come on if I plugged the power cord directly to the meter bypassing the switch. I tried multiple things before changing the fuse to insure it wasn't a connection problem with the wires or the switch itself. Once the fuse was replaced, everything worked as it should. I wanted to leave the rest of this review in the event it happens to someone else.Received the product October 2, 2024; voltage meter quit working on October 15, 2024.I used this to make a 12V battery box in the event of a power outage. Decided to see how long the battery would last just charging cell phones. This would have been the 3rd day of turning it on after charging the equivalent of 6 cell phones and the voltage meter doesn't come on. I checked the connections and the power switch, USB ports and 12V power plug all still work. I've had multiple people ask me to make them boxes, but I wouldn't feel comfortable building with this panel.

Great add on for my A-frame camper. Works exactly as expected. I can now charge stuff without getting the generator out. Very easy to install if you follow my steps below. Noticed some reviews complaining it was hard due to mounting bracket pod holes being close to edge. Almost didn’t buy so I figured I’d help someone else out.Install steps-screenshot / take picture of wiring diagram in pics on Amazon add. (2nd pic)-disconnect battery and any other power going to system (shore power)-find place you want it. I put mine by converter box so I didn’t have to add wire. Make sure nothing is behind for at least 6inchs so pods can fit with wires installed-install mounting bracket with 4 included screws. Don’t over tighten and strip hole.-use 1inch hole saw with drill. Try for center of mounting hole. Repeat 3 more times.-use a smaller drill bit with drill to take edge of new holes to plastic of mounting bracket. Like a router making the hole bigger but don’t cut the plastic. Go slow and test fit after.-wire up one at a time using pic. Don’t forget your pod retaining nut needs to go over wires before going to next one. Connect switch to 12v power and ground (directly down stream from battery is best for true reading)-make sure all connections are good and pods are tightened.-reconnect battery-test unit (should all light up with covers off and switch on) start testing usb with something cheep not phone. Same with car plug.-enjoy your job well done in hopefully an hour or less

All I can say is if you look back at why I chose these particular items is simply they work well and they are excellent products! When you are sailing you don't need to worry about any electrical problems these items come all equipped and you will never have to worry after that!
