Product Description
More Power for Bigger Engines
A basic jump starter is fine for a compact car, but full-size trucks, SUVs, and vans need more muscle behind them. The Lokithor J3250 PRO delivers 3250A of peak current, enough to start gas or diesel engines up to 7.5 liters, giving you real confidence the next time a larger vehicle won't turn over.
Right-Sized for Trucks and SUVs, Not Just Semis
Not every driver needs a commercial-grade jump starter built for 18-wheelers. The J3250 PRO sits right where most full-size trucks, SUVs, work vans, and towing vehicles actually need it, with enough reserve power for bigger engines without the bulk or price tag of Lokithor's heavy-duty commercial units.
A Connection You Can Count On
A poor clamp connection is one of the most common reasons a jump start fails. ConnectMax technology checks the connection between the clamps and your battery automatically, showing a green light for a solid connection or yellow for a poor one, so you can fix the contact before attempting to start the engine.
Built on a Battery Made to Last
The J3250 PRO runs on a Lithium Iron Phosphate (LiFePO4) battery, a chemistry known for staying stable under heavy use and holding its charge over the long haul. It's backed by seven layers of protection, including:
- Overvoltage and undervoltage protection
- Overcurrent protection
- High and low temperature protection
- Short circuit and reverse connection protection
More Than an Engine Starter
With a 74.25Wh battery and 100W USB-C input and output, the J3250 PRO doubles as a serious power source for charging phones, tablets, and other USB-C devices in the field. A 400-lumen LED light with steady, strobe, and SOS modes adds real visibility for roadside repairs after dark, and an IP65 rating keeps it working through dust and light rain.

Frequently Asked Questions
What size engines can the J3250 PRO jump-start?
A: It delivers 3250A of peak current, enough to start gas or diesel engines up to 7.5 liters, making it a good fit for full-size trucks, SUVs, work vans, and towing vehicles that need more power than a basic jump starter provides.
Is this powerful enough for a semi-truck or commercial vehicle?
A: It can handle larger gas and diesel engines up to 7.5L, but for semi-trucks, buses, or heavy commercial and industrial equipment, Lokithor's HD-series jump starters (like the J5000 PRO or J10000HD) are built with higher amperage for those larger applications.
Does the J3250 PRO have a built-in air compressor?
A: No. The J3250 PRO is a dedicated jump starter, power bank, and flashlight; it doesn't include a tire inflator. Lokithor's JA-series jump starters are built with an air compressor if that's a feature you need.
How do I know if the clamps are connected properly?
A: ConnectMax technology checks the connection quality automatically and shows a green light for a good connection or a yellow light for a poor one, so you can correct the contact before trying to start the engine.
Can I use it to charge my phone or tablet without jump-starting a vehicle?
A: Yes. It works as a standalone power source any time, with 100W USB-C input and output for charging phones, tablets, and other USB-C devices, whether or not you've used it to jump-start a vehicle.
