- Over-charge & over-discharge protection
- Over-current & short-circuit protection
- Over-temperature cut-off
Battery Capacity
This adapter is compatible with all battery capacities (Ah). However, weak or low-capacity batteries below ~3Ah may experience reduced performance or unstable operation. We recommend 4Ah or higher.

This adapter is a practical solution that gives your older Dyson vacuums a second life—without the cost of expensive replacement batteries.

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.
