Review on 🔌 Wagan 12V Automotive Socket Splitter and Extender, 4-Way Cigarette Power Splitter with Enhanced SEO by Nick Brunner

Mine comes with a 10A fast blow fuse (the one in your car for the socket, not the one in the 4th unit). extension plug). If the output fuse in the car is less than 10A, it will blow first. With such devices, you need to make sure that the fuse you want to blow first is selected for it. If a fuse blows, check for a short between +12V and ground in the connector. I just disassembled and inspected the four-way extension; Only the positive wire of the power plug is held by the terminal on the insulation, and the ground wire is only held by the core. If this crimp fails, the conductor can go to the +12V pin. The extension has an LED to monitor the voltage. The negative wire is longer than necessary and is not shielded. B. by a manufacturing or LED wire defect or by an impact (fall), the broken wire can move in the device and cause a short circuit. To avoid this, it should be quarantined or captured/preserved. In any case, the fuse in the plug or car socket should blow, unless the cause is a broken LED wire and the wire melts, in which case it may smoke briefly but otherwise continue to function. The plug wire is stamped 18AWG as you can see in one of the product photos. This should be listed on the datasheet on the Revain site, as should the amperage (10A). In fact, the Jan 16 listing says 110V as the spec, which is obviously wrong. Assembly parts are unlikely to fit most people. The screws are too short to cut into the surface of the vehicle and are kept from repeated insertion/removal of the connectors for a long time. The double-sided tape is too small to hold on. Try a strip of Velcro about 4 inches long, made up of either a single lengthwise strip or two 2-inch lengths (front to back next to the screws on the bottom). Otherwise, the device looks reasonably well put together for the purpose.
