LOKITHOR J1350 PRO 1350A Jump Starter LiFePO4 — 6.5L Gas / 3.5L Diesel, 30W Fast Charge, IP65

The LOKITHOR J1350 PRO is a portable 1350-amp LiFePO4 jump starter built to reliably start up to 6.5L gas and 3.5L diesel engines while offering fast two-way charging, rugged weather protection, and long service life.

Compact but heavy-duty, the J1350 PRO combines a high peak output, robust LiFePO4 battery chemistry, and smart safety features to make roadside starts faster and less stressful. It’s designed for drivers, tradespeople, and outdoor users who need a lightweight, long-lasting jump pack that can also charge phones and laptops and withstand dust and rain.

How quickly will the J1350 PRO start my vehicle?

The unit delivers 1350 amps peak current, enough to jump-start most 6.5L gasoline and 3.5L diesel engines. Because of its high output and ConnectMax impedance detection, it can achieve reliable starts within minutes under normal conditions.

• 1350 A peak starting current for fast cranking
• Rated for 6.5L gas and 3.5L diesel engines
• ConnectMax tech detects and optimizes clamp-to-battery connection
• Works in extreme temperatures from -4°F to 140°F

What makes the LiFePO4 battery better than other starter packs?

LiFePO4 cells provide longer cycle life and greater chemical stability than typical lead-acid or standard lithium batteries. The J1350 PRO’s battery is designed to last thousands of cycles and resist thermal runaway, so it maintains performance over years of use.

• More than 2,000 full cycles at 100% depth of discharge
• Up to 8,000 cycles at 50% discharge for extended lifespan
• Greater safety and chemical stability; less risk of overheating
• Long standby life — up to 24 months on a full charge

Can I charge my devices and how fast does the pack recharge?

The J1350 PRO functions as a portable power bank with two output ports and supports 30W two-way fast charging. It will top up mobile devices and small laptops while recharging itself in about an hour when using proper inputs.

• 30W two-way fast charging for quick in-and-out power
• USB-C and USB-A outputs for phones, tablets, and some laptops
• Full recharge in roughly 60 minutes under recommended conditions
• LED flashlight with flashlight, strobe, and SOS modes for emergencies

Is it durable and safe to use outdoors?

The pack is built for real-world conditions — rated IP65 for dust and water resistance and protected by ten integrated safety mechanisms. These safeguards reduce the risk of damage from incorrect hookups, overcurrent events, or environmental stressors.

• IP65 dustproof and water-resistant housing for outdoor use
• Ten protections: overcharge, short circuit, reverse polarity, and more
• Anti-spark and reverse charging protection for safer operation
• Compact form factor for storage in vehicles, toolboxes, or bags

Who is this for? The LOKITHOR J1350 PRO is ideal for drivers of larger gasoline or small diesel vehicles, fleet operators, mechanics, and outdoor professionals who need a rugged, long-lived jump starter that also doubles as a fast charger. If you want a compact pack with high starting power, strong safety features, and long cycle life for regular or emergency use, this model covers those needs.
