Car Jump Starter Lokithor J401 2500A, Powerbank 20000mAh

Lokithor J401 is a portable car jump starter and powerbank with a 74 Wh (about 20000 mAh) battery and a 12 V output. It delivers up to 2500 A peak current and is suitable for starting petrol engines up to 8.5 L and diesel engines up to 6.5 L. The device features an integrated flashlight, a 3.75" display that shows voltage, temperature and fault warnings, and includes clamps, a 12 V adapter, a USB-A to USB-C cable and a USB-C to USB-C cable.

Advantages

The Lokithor J401 combines jump-start capability and fast mobile charging in a single compact unit. A 74 Wh battery provides long runtime — up to about 60 starts on a single full charge — while standby drain is minimal. Fast charging ports (USB-C up to 100 W and USB-A up to 18 W) let you recharge phones and other devices quickly. Built-in protections (overload, short circuit, overvoltage, reverse polarity, overcharge and temperature safeguards) and an IP68 rating increase operational safety and reliability.

How to use

Charge the Lokithor J401 before first use via the USB-C input or DC input until the display shows full charge. To start a vehicle, connect the included clamps to the device and then to the battery terminals observing correct polarity; the built-in protections and display will warn of reverse polarity or unsafe temperature. Press the start function according to the user manual and start the engine. To charge external devices, connect them to the USB-C or USB-A port; the display indicates fast-charging status. After use, turn the unit off and store in a dry place within the recommended temperature range.

Usage recommendations

Keep the jump starter charged if you plan to store it for long periods — the device has very low standby drain but benefits from periodic charging. Always follow the included user manual and safety warnings when connecting clamps and using the starter; do not use if clamps or cables are damaged.
