Product Details

✓This adapter is designed to be compatible with both DeWalt 20V Max and Milwaukee M18 18V lithium-ion batteries (including XR and Redlithium series). It allows you to power your Dyson V7 and V8 cordless vacuums (including Animal, Absolute, Motorhead, Fluffy, SV11, SV10 models), effectively giving your old vacuum a second life.
✓Stop throwing away money on expensive OEM vacuum batteries that die quickly. By utilizing your existing high-capacity tool batteries (4.0Ah, 5.0Ah, 6.0Ah, etc.), this adapter provides significantly longer runtime compared to standard Dyson packs. Vacuum your entire house, car, or workshop on a single charge without the frustration of a dying battery mid-clean.
✓Installation is quick and tool-free. Simply slide your DeWalt or Milwaukee battery onto the adapter until it clicks, then insert the adapter into your Dyson vacuum just like a standard battery. The adapter features a premium ABS plastic housing with a secure locking mechanism, ensuring a wobble-free connection and stable power delivery during use.
✓The adapter features an LED indicator light (Green = Working, Red = Low Power). Note: This is an adapter only; it does not contain a battery and cannot charge batteries directly. To "recharge," simply remove the battery from the adapter and place it on your standard DeWalt or Milwaukee battery charger. This protects your expensive chargers and maintains safety.
✓Package Includes: 1x Multi-Brand Battery Adapter (Batteries and Vacuum NOT included). We stand by our quality with a 12-month warranty and responsive customer service. If you have any questions about compatibility (e.g., does this fit my specific battery model?), please contact us via Amazon before ordering for a quick response.
