Review on ⚡️ Blue Voltmeter Dual USB Rocker Switch Style Charger with Quick Charge 3.0 for Boats, Polaris, RZR 1000, Ranger, Mobile Home, RV, Can Am Spyders, Can Am Maverick, Can AM SxS, Golf Cart - Switchtec by Shedrick Roach

The product has arrived and meets all the specifications listed. Installed on a 2000 Jeep Wrangler SE. Used to replace a connector on a factory panel. The supplied wiring harness has high-quality connectors and works perfectly. It is very good that they include a built-in fuse. The only problem with vehicle mounting is that the wiring is only about 24 inches long. I decided to use wire taps and plug them into a switchable 12 volt cigarette lighter. Works perfectly! It is noticeable that the voltage drops slightly (0.1-0.2) when both USB ports are used. I believe this is because the voltmeter is local to the device and doesn't show the actual voltage drop across the entire on-board network.
