LOKITHOR JC400 2500A Jump Starter & 9-in-1 Car Battery Charger — Compact 12V Boost, USB-C Power Bank, LED Light

The LOKITHOR JC400 is a compact 9-in-1 car battery charger and 2500A peak jump starter that charges, maintains, desulfates, and jump-starts 12V vehicles while doubling as a portable power bank and LED emergency light.

Designed to fit in a glovebox or under a seat, the JC400 packs battery management, safety features, and versatile charging options into a palm-sized unit. It supports multiple battery types and offers a BOOST start for depleted batteries, plus USB-A and USB-C outputs to keep phones and accessories powered during roadside calls or outdoor trips.

How quickly will the JC400 get my vehicle started?

The JC400 delivers up to 2500A peak current and includes a BOOST start mode for deeply discharged batteries, enabling fast restarts for most 12V gasoline and diesel engines. It's rated to jump vehicles up to 8.5L gas or 6.5L diesel in seconds and works reliably across a wide temperature range.

• 2500A peak current for high-starting power
• Works with 12V systems only (not for 6V vehicles)
• Effective from -4°F to 140°F
• BOOST mode for very low or dead batteries

What charging and battery care options does it provide?

The JC400 is more than a jump starter: it offers three selectable charging currents (0.75A, 1A, 2A), a 7-stage charge profile, trickle/float maintenance, and automatic desulfation to treat sulfated batteries. Those modes help extend battery life and keep vehicles ready after long storage periods.

• Three output currents to match battery condition
• 7-stage smart charging for safe and efficient replenishment
• Automatic trickle to maintain batteries over months
• Pulse desulfator to recover neglected or stratified batteries

Is the JC400 safe and easy to use on the road?

Safety and simplicity are built in: smart clamps detect polarity, an integrated management system provides ten protections, and the device alerts you to improper connections. A clear 4.15-inch display shows voltage and charge status, while CONNECTMAX technology improves clamp contact for more reliable starts.

• 10 built-in protections including reverse-polarity and spark-proof
• Smart self-identifying clamps for automatic safety checks
• CONNECTMAX reduces impedance and improves clamp contact
• Readable display for real-time voltage and charging info

What extra features make this useful beyond jump-starting?

LOKITHOR added practical extras: dual USB ports (USB-A and USB-C) let you charge phones or small devices, and a 300-lumen LED with six modes provides light for nighttime repairs or emergencies. The internal high-rate battery holds charge long-term, making it dependable after extended storage.

• Dual USB outputs to charge phones, cameras, or laptops
• 300-lumen LED with SOS, strobe, and three brightness levels
• Low self-discharge and up to 27 months standby time
• Compact, rugged shell protects against water, dust, and drops

Who is this for? The LOKITHOR JC400 is aimed at drivers, fleet operators, and outdoor enthusiasts who want a single, compact tool that handles emergency jump-starts, routine battery maintenance, and device charging. If you store vehicles seasonally, tow, or travel in remote areas, this unit gives practical safeguards and multi-purpose utility without bulky equipment.
