LOKITHOR J3250 Pro Jump Starter 3250Amp

The LOKITHOR J3250 PRO is a high‑end 12‑volt jump starter packing serious power in a relatively compact, well‑protected package.

Its LiFePO₄ battery delivers about 74 Wh, and it can output a peak of 3,250 amps, allowing it to start gasoline engines up to approximately 9.5 L and diesel engines up to about 7.5 L.

One of its standout features is ConnectMax Technology, which automatically judges the quality of the clamp‑to‑battery connection by measuring impedance; it uses indicators (green for good, yellow for suboptimal) to help the user ensure optimal contact for reliable starts.

It also offers fast PD charging via USB‑C, a bright 400‑lumen LED flashlight with multiple modes, and multiple built‑in safety protections (reverse polarity, over/undervoltage, over temperature, etc.).

Main Features

  • The J3250 PRO delivers 3250A for gasoline engines up to 9.5L and diesel up to 7.5L, suitable for various outdoor tasks.
  • Its LiFePO4 technology lasts over 8,000 cycles at 50% discharge, far exceeding traditional batteries and lowering costs.
  • Fully recharged in 60 minutes, it can start your vehicle in just 3 minutes and powers USB-C devices with a 100W power bank.
  • Equipped with multiple safety protections, it ensures secure operation against sparks, reverse polarity, and overheating.
