Compact and portable jump starter adapter compatible with Dewalt 18V/20V Li-ion batteries. Provides safe and efficient jump-starting for cars with 12V batteries up to 3.5L engines. Built-in protections prevent short circuits, reverse connections, and overcurrent. Pulse charging helps revive weak car batteries. Lightweight and easy to store in your vehicle, this adapter is an essential automotive emergency tool.

Features

• Wide Compatibility: Works with Dewalt 18V/20V Li-ion batteries including DCB203, DCB204, DCB206, DCB606, DCB609, DCB612, DCB207, and more. Battery not included.
• Emergency Power Solution: Safely jump-start 12V car batteries (up to 3.5L engines) using Dewalt 18V/20V Li-ion batteries. Compact design for easy storage in your vehicle.
• Safe & Protective Design: No output before connection prevents short circuits and electric shock. Built-in current limiting protects both car electronics and the tool battery.
• Reverse Polarity Alert: Red & green indicator lights warn if positive and negative connections are reversed, ensuring safe operation every time.
• Pulse Charging Function: Revives weak or deeply discharged car batteries by delivering controlled pulse charging for better startup performance.

Important Safety Notes

• This product is an auxiliary jump starter and cannot directly start a car without connecting to the car battery.
  
• Only for cars with 12V batteries and engines up to 3.5L. Not for large vehicles or heavy-duty engines.
  
• Do not use if the car battery is completely damaged; the car will not start.
  
• Use original or high-quality tool batteries for optimal performance. Low-quality or old batteries may fail.
  
• Reverse connection alert: Red & green lights indicate incorrect connection.
  
• Short-circuit protection: Voltage across clamps may read 0V without a car battery connected. This is normal.

Operation Instructions

• Insert a compatible Dewalt 18V/20V lithium battery into the adapter; the green light will flash.
  
• Wait until the green light is steady, indicating readiness.
  
• Connect clamps to car battery: red = positive (+), black = negative (-).
  If red & green lights both flash, switch clamps immediately.
  If green & red lights flash alternately, battery charge is too low; use a fully charged tool battery.
  
• Once the green light is steady, start the car (typically 3–5 minutes charging).
  
• After the engine starts, remove clamps and battery from the adapter. Let the car run normally.
  
• Do not connect a tool battery directly to a car battery; the adapter safely converts voltage to 13.5V and limits current to 30A to protect electronics.
