Your Dyson

Dyson V8 is model HH15, SV10, SV10D, SV10E, SV10K or SV25

Only know your model number?

Look on the Dyson battery, next to its serial number. It is also on the serial-number sticker on the handle, hidden under the battery. It starts with SV, HH or DC.

Label says SV10? That is a Dyson V8, so you are in the right place. It is not a V10.

Estimated from battery energy, allowing for the adapter’s converter. Actual runtime depends on the power mode and the attachment fitted.

What still works on your Dyson V8

  • The trigger works as before.
  • Every power mode works, MAX included.
  • Motorised heads spin as usual, from the Motorhead to the mini motorised tool.
  • Wands, filters and the bin are unchanged.
  • The Dyson’s own battery lights stay off: check the charge on your battery’s gauge.
  • When the battery runs low, the adapter stops the vacuum to protect it.
  • The light on the side of the adapter is green when all is well and red when power runs low.

Fitting it to your Dyson V8

It only takes a few minutes, and nothing on your Dyson needs to be modified.

  1. Undo the 3 screws

    One is on the right side of the handle, the other 2 at the bottom left, between the bin and the battery. Keep them: you will need them again.

  2. Slide the Dyson battery out

    It comes straight out of the handle.

  3. Fit the adapter

    Slide it in where the battery was and put the 3 screws back.

  4. Click on your battery

    Your DeWalt 20V MAX battery locks onto the adapter. Pull the trigger and clean.

Changed your mind? The original battery goes back the same way.

DeWalt 20V MAX to Dyson V8: Common Questions

Which Dyson V8 models does this adapter fit?

It fits the Dyson V8 range: HH15, SV10, SV10D, SV10E, SV10K, SV25. It does not fit the Dyson V8 Cyclone, SV55.

My battery says 20V. Will it run my Dyson V8?

Yes. 20V is what a DeWalt 20V MAX battery measures off the charger with no load; 18V is what it holds in use. The adapter takes it from there, so your Dyson V8 gets the power it is built for.

Will this fit my other DeWalt batteries?

Only DeWalt 20V MAX batteries. DeWalt also sells DeWalt 12V MAX, DeWalt 18V Ni-Cd, and those use a different socket: same brand, different rail and contacts, so they need their own adapter. Compare the rail on your battery with the photos before ordering.

Will my Dyson V8 run as long on your DeWalt 20V MAX battery?

Runtime comes from the battery, not the adapter: a 5.0Ah DeWalt 20V MAX battery lasts roughly twice as long as a 2.5Ah one. For this pairing use 3.0 Ah or more, because a smaller battery can sag under what a Dyson V8 draws and cut out before it is empty.

Could this damage my DeWalt 20V MAX battery or my Dyson V8?

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 vacuum 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 V8: there is no charging circuit inside it, and the vacuum’s dock cannot charge through it. Always take the DeWalt 20V MAX battery off the adapter and charge it on its own charger.

Does it work with third-party DeWalt 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 V8 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 V8?

114 g (4.0 oz), plus your battery, which sits under the handle where the original battery was. You notice the extra weight on stairs or when reaching up high; on floors it soon feels normal.

Exactly what I was after, quick delivery. Super happy that my Dyson now lasts longer and I can change the battery for another without having to wait for it to charge (not that I have needed to as it lasts long enough to do the whole house now!)

Excellent. Very easy to install. Much longer run time with the Milwaukee battery compared to original Dyson.

This adapter has renewed my old Dyson vacuum. Super easy to install, only two screws. Just keep Dewalt batteries nearby and we are good to go.

The clip to hold the adaptor in the handle of the vacuum is difficult to latch, but otherwise it works great!

DeWalt 20V MAX and Dyson V8 compatibility

It works in one direction only: DeWalt batteries powering your Dyson.

Compatibility can vary with the exact battery and vacuum model. Before ordering, confirm that your battery belongs to the DeWalt 20V MAX platform and that your vacuum is a Dyson V8: the model number on its label tells you.

Important charging and safety information

This adapter is for powering your vacuum and nothing else. It cannot charge DeWalt or Dyson batteries and must never be connected to a charger or the vacuum’s dock. Always take the battery out of the adapter before charging, and charge it on the original charger made for your DeWalt 20V MAX battery.
