Product Details
✓⚙️ Designed Specifically for Harpy Eagle Oil Extractor Pump: This battery adapter is purpose-built to transform your Harpy Eagle Oil Change Extractor Pump into a cordless tool. No need to rely on a vehicle battery — perform oil changes anywhere, even in tight spaces like gearboxes, rear axles, and small engines.
✓📦 Complete Connection Kit – No Soldering Required: Everything you need is included: pre-wired DeWalt-style adapter, WAGO lever connectors, inline fuse holder (30A), spare fuses, and durable 12 AWG wire. Installation takes less than 10 minutes using only a basic wire cutter.
✓🛠 Step-by-Step Setup Instructions Built In: To install, cut the original power cable 4–6 inches from the pump. Strip 1.5 inches of the outer insulation and 0.38 inch (9–10mm) of red and black wires on both ends. Connect matching wires using the included WAGO connectors (red to red, black to black). Insert a fully charged DeWalt 20V battery — and you're ready for mobile operation.
✓🔋 Built for High-Current Operation with Safety First: Designed for safe high-power use with a pre-installed 30A fuse and two spares. The heat-resistant ABS housing, waterproof fuse cap, and thick 12AWG silicone copper wiring provide stable power even in challenging conditions. Recommended usage: 10 minutes ON / 10 minutes OFF.
✓🔌 Compatible with DeWalt 20V MAX Lithium Batteries: Securely fits popular DeWalt 20V / 18V DCB models including DCB205, DCB206, DCB204, DCB203, DCB200, DCB201, and more. Locks firmly into the battery, ensuring a stable connection. Adapter includes mounting holes for optional fixed installation on walls or tool stations.
✓🧠 Helpful Usage Notes for Safe Operation: This adapter is not a charger — it transfers voltage directly from your DeWalt battery to the pump. Always match red wires to positive (+) and black wires to negative (–) when connecting. Remove the battery after each use to prevent discharge. Follow 10-minute duty cycle to protect both pump and battery.
