How this adapter is measured

An angled drawing of the adapter, with its length, width and height marked. The latch on top is inside the height. Height 128 mm (5.04 in) Width 81.5 mm (3.21 in) Length 150 mm (5.91 in)
  • Latch
  • Adapter body

Measured across the outside of the part. The height includes the latch, so this is the space the adapter needs.

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 55A continuous with 100A peak at 18VDC for up to 2 seconds, so a high-draw tool is not held back by the adapter.
  • Made for the RIDGID 18V batteries sold at Home Depot, so the fit is the one you already own.
  • Covered by a 12-month warranty from the day it arrives.

RIDGID 18V and Dyson V7 compatibility

It works in one direction only: RIDGID batteries powering Dyson tools. For the opposite pairing, see adapters that run on Dyson V7 batteries.

Compatibility can vary with the exact battery and tool model. Before ordering, confirm that your battery belongs to the RIDGID 18V platform and that your tool takes Dyson V7 batteries.

Important charging and safety information

This adapter is for powering cordless tools and nothing else. It cannot charge RIDGID 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 RIDGID 18V battery.

How it works

  1. 1. Use the battery you own

    Any compatible RIDGID 18V battery of 3Ah or more.

  2. 2. Slide on the adapter

    It goes where the original Dyson V7 battery sits.

  3. 3. Click in and work

    No tools, no wiring, no modifications.

RIDGID 18V to Dyson V7 — Common Questions

Will this fit my other RIDGID batteries?

Only RIDGID 18V batteries. RIDGID also sells RIDGID 18V RED, 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 V7 tool run as long on a RIDGID 18V battery?

Runtime comes from the battery, not the adapter: a 5.0Ah RIDGID 18V battery lasts roughly twice as long as a 2.5Ah one. For this pairing use 3.0 Ah or more — a smaller battery can sag under what a Dyson V7 tool draws and cut out before it is empty.

Could this damage my RIDGID 18V battery or my Dyson V7 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 V7 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 RIDGID 18V battery off the adapter and charge it on its own charger.

My RIDGID 18V gear came from Home Depot. Is that the same platform?

Yes — Home Depot is where RIDGID 18V is sold, so a battery or tool bought there is the platform this adapter is built for. What matters is the socket, and Home Depot stock is the reference for it.

Does it work with third-party RIDGID 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 V7 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 V7 tool?

124 g (4.4 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.

Totally recommend, my AEG battery works a treat.
Works a lot better with the adapter, takes 3-4 vacuums before I charge it.
Perfect.

Worked as advertised. Couldn’t ask for more.

Great Product! It was cheaper than a new battery and my vacuum now has much longer run times, stronger suction, and simple, faster charging with my power tool batteries. I'll be buying more of these adapters for my other devices.

This is a very well engineered product. Installation took maybe a minute, and the Ridgid batteries can run the Dyson at high speed for longer than the original did. I 3d printed a hook to hang up the Dyson and did away with the big, rickety mount.

So now I have a Dyson with two 4 amp-hour batteries which have Ridgid's lifetime service agreement. It doesn't get any better.

This unit was 100% useful and a game changer for the Dyson Vacuum! It is top quality! I've actually forwarded these items to many of my friends who have actually purchased one.
