Cordless Car Wash Gun 21V 300W — Dual-Battery, 3MPa High-Pressure Kit
$126.99
300W motor, 3MPa working pressure, 4.5L/min flow — highest continuous output in this cordless lineup. Dual-battery kit for extended cleaning sessions without stopping to recharge. ABS housing at 2.9kg. For homeowners who run their cordless tools hard.
The Highest-Output Cordless Unit in This Lineup
Three numbers tell the story: 300W motor, 3MPa (roughly 435 PSI) working pressure, and 4.5L/min flow rate. Multiply pressure by flow and you get the highest Cleaning Unit output in this cordless segment. That combination means faster rinse cycles on larger surfaces and more effective penetration on embedded grime — the kind found in wheel wells, concrete edges, and weathered decking.
Performance & Specifications
Motor & Output
- Motor: 300W
- Voltage: 21V lithium
- Working pressure: 3MPa (≈ 435 PSI)
- Flow rate: 4.5L/min — highest in this cordless lineup
- Hose: 1.5m (short tether — use the unit close to the work area)
Why Dual Battery
At 300W output, a single battery depletes faster than lower-wattage models. The dual-battery configuration is the right setup for this power level — run one pack, charge the other simultaneously, keep working. For a vehicle that takes 30–45 minutes to wash properly, that uninterrupted runtime matters.
Build
- Housing: ABS
- Weight: 2.9kg
Right Tool, Wrong Tool
The Right Fit
Homeowners with larger vehicles, heavier cleaning workloads, or surfaces that demand more than 260W can deliver. SUVs, trucks, driveways with moderate concrete staining, and extended sessions where single-battery tools would require a mid-job stop.
The 1.5m Hose Constraint
The hose on this unit is shorter than the 5–10m options on other models. You’ll position the unit closer to the work area and move it as you go — a different workflow than the longer-hose models. Worth knowing before you purchase.
Frequently Asked Questions
How does 3MPa compare to other units in bar?
3MPa = 30 bar. That sits below the 50bar TJ02 and 120bar EPW02-005 in absolute pressure terms, but the 4.5L/min flow rate is the highest in the lineup. Cleaning Unit output (pressure × flow) is what determines real-world performance — not pressure or flow in isolation.
Is 2.9kg manageable for extended one-handed use?
For short sessions, yes. For 30+ minutes continuous, most users find two-handed operation more comfortable at this weight. Plan your workflow accordingly if fatigue is a concern.
