Your Dyson

Dyson V10 is model SV12, SV12G, SV27 or SV58

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, not a V10.

Use your DeWalt 20V MAX batteries on your Dyson V10, with no new Dyson battery to buy. The molded ABS housing keeps it light and hard-wearing, and pure copper contacts keep current delivery steady. The batteries you already charge for your tools now clean the house too, with no extra charger to keep. It also carries battery protection electronics (BMS) inside.

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 V10

  • 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.

Fitting it to your Dyson V10

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

  1. Undo the 3 screws

    One is on the handle, the other 2 on the front of 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 V10: Common Questions

Which Dyson V10 models does this adapter fit?

It fits the Dyson V10 range: SV12, SV12G, SV27, SV58. It does not fit the 285O, 285P, SV18, SV55-A, SV55-AE, V10 Konical.

My battery says 20V. Will it run my Dyson V10?

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 V10 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 V10 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 4.0 Ah or more, because a smaller battery can sag under what a Dyson V10 draws and cut out before it is empty.

Could this damage my DeWalt 20V MAX battery or my Dyson V10?

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 V10: 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 V10 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?

192 g (6.8 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.

DeWalt 20V MAX and Dyson V10 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 V10: 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.
