The Lokithor JTC4250 is a powerful jump starter with LiFePO4 technology that combines a booster, a 6 V/12 V charger, and a 12V battery tester. With a capacity of 89.6 Wh and a peak current of 4250 A, it helps you quickly start a wide range of vehicles while also offering smart features, high safety, and convenient USB charging.
Extreme starting power up to 4250 A
A peak current of 4250 A and stable operation enable quick starting of both 6V and 12V vehicles. An ideal solution when the battery fails on the road or in more demanding conditions.
6 V / 12 V battery charger up to 90 W
The Lokithor JTC4250 also works as a battery charger and supports 6V/12V batteries up to 120 Ah. Thanks to the 100–240 V input and max output of 90 W, you can conveniently recharge your battery without additional equipment.
LiFePO4, ConnectMax and safety protections
Modern LiFePO4 cells deliver stability and a lifespan of over 2000 cycles. ConnectMax technology improves clamp contact with the battery, and the device is protected against overvoltage, undervoltage, overload, overheating, overcooling, short circuit, and reverse polarity.
The Lokithor JTC4250 jump starter is designed for situations when you need to revive a discharged battery quickly and safely. Its high starting performance handles both 6V and 12V systems, and the device also serves as a battery charger and a diagnostic tester. It is suitable for everyday use, travel, and the workshop.
The advanced ConnectMax function automatically evaluates the quality of the clamp connection to the battery and adjusts parameters for the most efficient start. Long service life is ensured by LiFePO4 cells (over 2000 cycles), and comprehensive protections are included against overvoltage, undervoltage, overload, overheating, overcooling, short circuit, and reverse polarity.
