My FEANISIFEI electric jack set is one of the best road tools I have ever had. It allowed me to change tires faster, safer, and more comfortably than ever before with traditional mechanical jacks. The included impact wrench took care of the cleats my dealer re-tightened, and multiple saddle adapters mean I can use it on almost any car or SUV, whether it's mine or a motorist stranded on the side of the road. Very solid construction, the jack is quite heavy but certainly no more than most drivers can handle. Packed in a sturdy plastic carrying case (with nice metal clasps!), my FEANISIFEI electric jack kit is easy to carry, fits perfectly in the trunk or back compartment, and protects tools from dirt and snow when opened for use. on earth. While the jack and wrench can be powered from the cigarette lighter, they must supply twelve amps, which some vehicles may not be able to do. Luckily, it comes with an adapter that allows me to plug it directly into the car battery, which is a much more reliable option. The FEANISIFEI Electric Car Jack Kit is packed with accessories, including a pair of lug nuts and a set of spare fuses. to an emergency shard/seatbelt cutter and, very thoughtfully, a pair of cotton work gloves and even a handle in case your power goes out. In short, this is an exceptionally useful and well thought out kit for that all too common road repair, flat tyre, and I recommend it.
