Common Questions
Which Dyson does this fit?
This adapter is model-specific — the title and description show which Dyson it fits (V6, V7, V8 or V10).
What battery capacity do I need?
At least 3Ah — anything below that won't power the adapter. We recommend 4Ah or higher for the best runtime.
Do I need any tools or modifications?
No. It clicks onto your Dyson with no wiring, cutting or permanent changes.
Can I charge the battery on a Dyson charger?
No. Charge it on its own power-tool charger — the battery cannot be charged on a Dyson charger or through the adapter.
