Product Description
One Tool Instead of Three
Jump-starting a dead battery, testing whether it's actually still good, and charging it back up usually means owning three separate tools. The Lokithor JTC4250 combines all three into one device. With 4250A of peak current, it starts gas engines up to 10.0 liters and diesel engines up to 8.0 liters, so the jump-starting side alone covers most cars, SUVs, and trucks.
Know What's Actually Wrong With Your Battery
Not every no-start is a dead battery, and not every dead battery is worth jumping. The built-in battery tester runs a starting test, a charging test, and an overall health check on your 12V battery, so you get a real answer instead of a guess. Bluetooth connectivity sends that data straight to the Lokithor app, so you can check the results on your phone instead of squinting at the unit itself.
A Real Battery Charger, Not Just a Booster
A jump starter gets you moving, but it doesn't fix a battery that's genuinely worn down. The JTC4250 also works as a smart charger compatible with 6V and 12V lead-acid and LiFePO4 batteries, with four charging modes for different battery types and conditions. That means you can bring a weak battery back to a full, healthy charge at home instead of just topping it off enough to limp to the next stop.
A Connection You Can Trust
ConnectMax technology checks the connection between the clamps and your battery automatically, helping ensure solid contact whether you're jump-starting, testing, or charging. It's one less thing to second-guess when you're troubleshooting a battery problem.
Built to Handle Regular Use
Running on a LiFePO4 battery rated for over 2,000 recharge cycles, the JTC4250 is built for drivers and DIYers who'll actually use it often, not just once a year in an emergency. An IP65 rating and a 300-lumen LED flashlight round it out for use in the driveway, garage, or on the road.

Frequently Asked Questions
What size engines can the JTC4250 jump-start?
A: It delivers 4250A of peak current, enough to start gas engines up to 10.0 liters and diesel engines up to 8.0 liters, covering most cars, SUVs, and light trucks.
What's the difference between the jump starter and the battery charger functions?
A: The jump starter delivers a quick burst of power to start your engine right away. The battery charger is separate: it slowly and fully recharges a 6V or 12V lead-acid or LiFePO4 battery over time, the way you'd use a charger left connected overnight, so your battery comes back to a genuinely healthy charge rather than just enough to start the car.
What battery types does the charger work with?
A: The built-in smart charger supports both 6V and 12V lead-acid batteries as well as 12V LiFePO4 batteries, with four charging modes to match different battery types and conditions.
How does the battery tester and Bluetooth app work?
A: Connect the clamps to your battery and the JTC4250 runs a starting test, a charging test, and a health check. Pair it with the Lokithor app over Bluetooth to view that test data in real time on your phone instead of reading it off the unit.
Is it safe to use if I'm not an experienced mechanic?
A: Yes. ConnectMax technology checks the clamp connection automatically, and the battery tester is designed to walk you through a clear health check rather than requiring you to interpret raw diagnostic data yourself.
