Sobre este artículo

  • No Pre-Charge Needed & Batteryless Design for Instant Use:Built with advanced supercapacitor technology, the JS200 requires no pre-charging at home—simply rely on your car’s weak battery or quick external charging to get started in seconds. Without internal traditional batteries, it’s eco-friendly, maintenance-free, and avoids the hassle of regular recharging, making it a reliable emergency solution for unexpected battery failures.
  • Permanent Mount & Battery Life Extender (Exclusive Advantage):Designed as a permanent installation accessory, the JS200 eliminates frequent disassembly and storage—install it once and enjoy long-term convenience. Beyond emergency starting, it actively extends your original car battery’s lifespan by stabilizing voltage and reducing wear from repeated charging/discharging (the main cause of battery damage), saving you costs on battery replacements.
  • Powerful Performance & Fast Charging for 12V Passenger Cars:Boasting a 700A discharge current and 15V max output voltage, it effortlessly starts all 12V passenger cars. Supports dual fast charging methods: Type-C (5V/2A) charges in 3~50 minutes, while direct car battery charging takes only 3~22 minutes—get back on the road quickly without long waits.
  • Extreme Temperature Resistance & Ultra-Long Lifespan:Withstands harsh environments from -40℃ to 80℃ (-40°F to 176°F), delivering consistent performance in blizzards, scorching heat, or other extreme weather. Engineered for 500,000 charge-discharge cycles, it outlasts traditional battery jump starters, providing durable reliability for years of use.
  • Smart Bluetooth Connectivity & Wide Voltage Compatibility:Equipped with Bluetooth BLE 5.3, you can real-time monitor the jump starter’s status (e.g., charge level, connection) via your smartphone for added peace of mind. Features a 5~20V wide working voltage range, adapting to diverse power supply scenarios, and ensures safe use with reverse polarity protection, overcurrent protection, and overload protection.

Excellent technology, bluetooth app gives full health picture of your battery so no surprises

I just received this unit and the concept is very cool. Currently I live in Georgia and we get a few days below 30 degrees and that's enough to kill a battery that's only a couple years old but more importantly when you really need it like getting to work. I am planning a move to Colorado and obviously a lot more colder days, so this seemed a great product for back-up protection. The capacitor is very light weight, housing is plastic and not so thick as I can actually squeeze it and the housing will flex. Leads are a thick gauge and good quality. I do wish there were better mounting options verses the included velcro maybe mount points you can bolt to the battery terminals. Unit also came with a chrome vanadium wrench that now resides in my tool bag. What's really great is the bluetooth app for your phone. You can see health readings and add a boost to start your car even if your voltage drops down to 6v which is impressive. The unit also has LED indicators for status and an emergency start feature. I believe this will give me visual warnings when my battery is nearing its terminal life span so I won't get caught on the side of the road with a dead battery ever again. There should be these units on every new car. There's a lot to this technology and like being better prepared. It's a little pricey but the peace of mind is great and never being late for work due to a dead battery, or whenever you really need your vehicle to start, priceless. Read more
