Lokithor J3250 Pro 74.24 Wh 3250 A Jump Starter (J3250 PRO)

LOKITHOR J3250 Pro 74.24Wh 3250A Jump Starter
The LOKITHOR J3250 PRO is a high-performance car starter with a peak current of 3250A, designed to start gasoline engines up to 9.5L and diesel engines up to 7.5L. The unit uses a modern LiFePO4 (LFP) battery, offering over 8,000 charge cycles at 50% discharge, which significantly extends service life and reduces operating costs. This model combines the functions of a jump starter and a 100W power bank with fast, bidirectional charging—a full charge takes approximately 60 minutes. Its robust construction, advanced safety features, and resistance to harsh conditions make it ideal for both everyday use and emergency situations.

High power and wide range of applications
The starter provides a 3250A cranking current, enabling it to start a variety of vehicles—from motorcycles and passenger cars to SUVs, pickups, and larger commercial vehicles. Thanks to its support for large engines, it performs well in both everyday use and when working in more challenging off-road conditions.

LiFePO4 technology and long service life
The lithium iron phosphate battery used guarantees exceptional durability and stable performance over a long period of time. Over 8,000 charge cycles at partial discharge translate to many years of use without any drop in performance. Additionally, the very low self-discharge rate (0.66 mAh) allows the device to remain ready for use for up to 42 months after a full charge.

Fast charging and power bank function
The built-in 74.24Wh power bank allows you to power mobile devices such as smartphones or laptops. 100W bidirectional USB-C fast charging allows you to quickly charge the starter itself as well as connect other devices. The device offers various ports, including USB-A, USB-C, and a DC output, which increases its versatility.

Smart systems and safety
The J3250 PRO model is equipped with ConnectMax technology, which automatically analyzes the connection quality with the battery and detects potential issues, such as dirt or poor contact. The entire system is supported by as many as 10 safety systems, protecting against reverse polarity, short circuits, overheating, overloading, and overcharging, among other things. A clear display shows voltage and any errors, facilitating safe use.

Durability and Additional Features
The IP65-rated housing protects the device from water and dust, allowing it to be used in harsh weather conditions at temperatures ranging from -4°F to 140°F. The built-in 400-lumen LED flashlight offers standard, strobe, and SOS modes, enhancing safety after dark.

Simple operation and package contents
The device is intuitive to use—in standard mode, simply connect the clamps, start the unit, and start the vehicle. Boost mode allows for starting even with very low battery voltage. Its compact dimensions (10.67 × 3.78 × 8.34 inches) make it easy to store, and the kit includes cables with clamps, a manual, and a carrying bag.
