12V Solar Car Batttery Trickle Charger Power Harness Kit 18AWG SAE Quick Connector with Cigarette Lighter Plug&Socket&Alligator Clips&DC5521&Extension Cord&Tester for Solar Panel Boat Mower - Shenzhen Jinkaiming Electronics Co., Ltd., JKM-WTZ-018

• 【For Most Applications】This set is equipped with four options: SAE to male/female cigarette lighter, DC5.5x2.1mm barrel adapter, and battery clamp. Can be used to power devices from car batteries or to power batteries through solar panels. SAE extension cable can provide 16FT distance for connection. 【SAE Harness Volt Tester】This tester can detect whether there is voltage or signal in SAE harness. The round hole end is negative and the exposed end is positive, insert it into the SAE port of the tested harness(If polarity backward, use reverse adapter). When the LED light of the tester emits light,there is a voltage in the measured harness. 【Wide Applicability】Widely used in a variety of solar battery panel and vehicles, such as snowmobile, lawn mowers, ATV, RV, troll motors, tractor sprayers, inverters and other equipment you want to charge. The polarity of SAE sockets from different brands may vary, and the kit includes a SAE polarity reversal adapter to address this situation. 【7 Items Included】1xSAE extension cord 5m/16.4ft, 1xSAE to DC5.5x2.1mm(center+) cable 0.3m/0.98ft, 1xSAE to battery clamps cable (SAE female+) 0.3m/0.98ft, 1xSAE to cigarette lighter male(with 5A Fuse) cable 0.3m/0.98ft, 1xSAE to cigarette lighter female cable 0.3m/0.98ft, 1xSAE harness voltage tester, 1xSAE polarity reverse adapter 【Please Note】Just suitable for 12 Volt DC Systems.
