Why choose this adapter
- A Battery Management System inside the adapter cuts power before the battery is drained too far — protection your battery may not have on its own.
- Injection-moulded ABS, not 3D printed — no layer lines to split under load.
- Solid copper terminals, so less of the current is lost as heat.
- Rated for 60A continuous with 100A peak at 18VDC for up to 2 seconds, so a high-draw tool is not held back by the adapter.
- Covered by a 12-month warranty from the day it arrives.
Stanley V20 and Dyson V10 compatibility
It works in one direction only: Stanley batteries powering Dyson tools. For the opposite pairing, see adapters that run on Dyson V10 batteries.
Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the Stanley V20 platform and that your tool takes Dyson V10 batteries.
Important charging and safety information
This adapter is for powering cordless tools and nothing else. It cannot charge Stanley or Dyson batteries and must never be connected to a charger of any kind. Always take the battery out of the adapter before charging, and charge it on the original charger made for your Stanley V20 battery.
How it works
-
1. Use the battery you own
Any compatible Stanley V20 battery of 4Ah or more.
-
2. Slide on the adapter
It goes where the original Dyson V10 battery sits.
-
3. Click in and work
No tools, no wiring, no modifications.
Stanley V20 to Dyson V10 — Common Questions
Which Dyson V10 models does this adapter fit?
It fits the Dyson V10 range: 285O, 285P, SV12, SV12G, SV27, SV55-AE, SV58. It does not fit the SV18.
My battery says 20V. Can it run a tool rated differently?
Yes, and they are closer than the labels suggest. 20V is what a Stanley V20 battery measures off the charger with no load; 18V is what it holds in use. Dyson V10 tools are built around 25.2V. The two numbers describe the same class of battery, which is why the adapter works rather than merely fits.
Will my Dyson V10 tool run as long on a Stanley V20 battery?
Runtime comes from the battery, not the adapter: a 5.0Ah Stanley V20 battery lasts roughly twice as long as a 2.5Ah one. For this pairing use 4.0 Ah or more — a smaller battery can sag under what a Dyson V10 tool draws and cut out before it is empty.
Could this damage my Stanley V20 battery or my Dyson V10 tool?
Used with undamaged, compatible equipment it is not expected to. This adapter has its own Battery Management System, which cuts power before the battery is drained too far, so it protects the battery even where the battery has no protection of its own. Stop using it if the adapter becomes unusually hot, the contacts look damaged, or the tool behaves oddly.
Can I charge through the adapter?
No, and it should never be attempted. The adapter carries power one way only, out to the Dyson V10 tool — there is no charging circuit inside it. Connecting it to a charger puts the battery, the charger and the adapter at risk. Always take the Stanley V20 battery off the adapter and charge it on its own charger.
Does it work with third-party Stanley batteries?
Usually. What matters is the socket, not the badge: if the battery slides on and locks the way an original does, the adapter takes it and the Dyson V10 tool runs. Aftermarket moulding does vary, so if yours looks unusual send us a photo and we will check before you order.
How much does it add to the Dyson V10 tool?
197 g (6.9 oz) and a short extension between battery and tool. You notice it overhead or in a tight cabinet; on a drill or driver held normally it disappears.
