STANLEY Lithium Jump Starter 1800 Peak Amps — Compact 12V V8 Ready with USB-C PD 30W & Carry Case

Compact yet powerful, the STANLEY FATMAX LJ18FC delivers high-current starting capability in a portable package with safety features and modern charging ports. Designed to be easy to stow in a trunk or garage, it combines jump-starting performance, reverse-polarity protection, and USB-C/USB-A charging so you can revive a dead battery and recharge devices from the same unit.

How quickly will this starter get a vehicle running?

The LJ18FC provides 1800 peak amps for immediate starting power suitable for most gasoline engines up to eight cylinders. Peak amps give the burst needed to crank an engine; typical use cycles should be short and follow the included instructions for safety. For deeply discharged or damaged batteries, professional service may still be required.

• 1800 peak amps for instant cranking power
• Suitable for most 12V cars and trucks up to V8 engines
• Powder-coated metal clamps for reliable contact
• Reverse polarity protection prevents incorrect connections

What charging and power delivery options does it offer?

This model doubles as a portable power bank with a USB-A output and a USB-C PD port for faster charging of laptops, tablets, and phones. It supports Power In & Out so the internal battery can be replenished and then used to power devices or jump a vehicle. The USB-C PD 30W output supports modern devices that require higher wattage.

• USB-C PD (30W) for fast charging compatible devices
• USB-A (15W) for phones and accessories
• Power In & Out ports to charge the unit and external gear
• Compact form factor fits a carry case or vehicle compartment

What safety and convenience features are included?

Safety is built in with reverse polarity protection so the starter won’t operate if clamps are improperly connected, reducing the chance of sparks or damage. The included bright LED work light helps illuminate roadside repairs after dark, and the powder-coated clamps resist corrosion for longer life. The unit ships with a zippered carry case for tidy storage and transport.

• Reverse polarity protection for safe hookup
• Bright LED work light for nighttime use
• Durable, powder-coated metal clamps to maintain conductivity
• Included carrying case for protection and organization

Who is this for: The STANLEY LJ18FC fits drivers who want a compact, reliable jump starter for everyday vehicles, commuters who need backup power on the go, and DIYers who appreciate an integrated power bank with safety features. It’s suited for owners of cars and light trucks with 12V lead-acid batteries (AGM, GEL, and WET types) who want a portable, multi-functional emergency power solution without the bulk of traditional starters.
