Design is not just about pursuing beauty; more importantly, it’s about solving users’ practical problems.
Among Shenglan Auto Products’ numerous offerings, there are some designs you might not pay much attention to. At first glance, they may seem like a matter of course, but in reality, they embody our thinking on "how to further enhance usability." What matters most is that these designs can help us solve real problems in specific scenarios.
Take, for example, Shenglan Auto Products’ multi-functional jump starter & air compressor—JCTC-139PLUS!
Most emergency jump starters on the market have a boxy, industrial, "brick-like" design. We all know jump starters are used to charge cars, but they actually have more applications: charging mobile phones, laptops, digital cameras, tablets, and other electronic devices.
In such moments, you can simply "carry" this large power bank from the car trunk to recharge your devices in time. When they’re fully charged, your sense of security is fully restored too.
All input and output ports of the JCTC-139PLUS are located on the top. It features 2 USB-A QC3.0 fast-charging ports (18W each) and 1 Type-C PD 65W port, along with an EC5 jump-start output port. The total power output reaches QC18W + PD65W. Equipped with 4 built-in 5000mAh batteries, it has a maximum capacity of 20000mAh. Both large and small plugs can be used simultaneously without interfering with each other. The front of the device is designed with a mirror finish, adding a touch of sophistication. This side only houses a large digital screen and the control panel, perfectly blending style and functionality.
Its powerful current delivers robust performance. Jump-starting cars with dead batteries is its primary function. Boasting a starting current of 1500A and a peak current of 3000A, here’s how it works when your car battery dies: plug the smart clamp into the JCTC-139PLUS’s EC5 port, then attach the alligator clips to the car battery’s positive (red) and negative (black) terminals—always positive first, then negative. Once secured, get in the car, press the start button while holding the brake, and it will easily jump-start 12V gasoline cars with a displacement of 8.0L or less, and 12V diesel cars with a displacement of 5.0L or less. After 30 seconds, you can return to the battery, remove the clips, and you’re done. The operation is simple, and jump-starting is completed in one step.
In fact, the JCTC-139PLUS offers more than just that! When driving in busy traffic, apart from worrying about running out of fuel or battery, flat tires or low tire pressure can also cause great stress. A 2-in-1 product that charges and inflates, ready to use anytime, is definitely a welcome solution. That’s why we firmly believe:
2-in-1, multi-functional product designs deserve to be used in more scenarios.
Hidden on the back of the JCTC-139PLUS is an air hose and three different nozzles, ready to inflate car tires at any time. Beyond emergency car tire inflation, it can also be used for motorcycles, bicycles, and basketballs. For example, inflating a 195/65 R15 tire from 0 PSI to 36 PSI takes less than 7 minutes—impressive efficiency! When not in use, just close the back cover, and you’ll barely notice it’s there.
Additionally, the right side of the device features alternating red and white flashing lights, which serve as a strong warning to oncoming vehicles in emergencies. It also has lighting, SOS, and small round light flashing functions. In comparison to similar products on the market, Shenglan Auto Products’ JCTC-139PLUS multi-functional jump starter & air compressor stands out in terms of appearance, texture, and performance.
To circle back to our core idea: design is not just about beauty—it’s about delivering a smoother user experience on top of aesthetics. This value is reflected in the interaction between users and the product, i.e., the user experience. Users’ recognition of the product is essentially recognition of us and their yearning for a better life. Developing and producing practical yet beautiful products is something we’ve always been committed to.
