Review: Brought a Dyson I found discarded back to life! - I’m so glad I found this item. I found a discarded Dyson vacuum was thrown out for bulk item pickup. I brought it home and discovered the battery wss no good. Popped this guy in (just one screw), threw in my Dewalt battery and boom! A fully functional Dyson working as good as it probably did day it was bought! This thing saved me 200$ and gave me a free 500$ vacuum on top of it!! Very pleased!! Installation was very simple, just one screw! It matches the vacuums color scheme and looks like it was built by the OEM. It had a status light that turns on while in use. Keep in mind however, this adapter will NOT charge your battery but you should know this already. You should only charge your tool battery in a the charger designed by your manufacturer. Thankfully they thought of this by removing the power plug that was normally present in the original battery so you don’t accidentally plug your Dyson charger into this to charge your tools battery. If your vacuum is not working, consider this before buying a 250$ battery replacement. You will be pleased!
Review: DOES NOT WORK WITH POWERSTACK 5AH - Giving this 5 stars because it took 30 seconds to swap out, was super affordable, and works with all of my batteries big and small except my new powerstack 5ahs. The vacuum will not run with it, it tries to but it sounds like it’s dying of thirst from no juice. Swapped it out with a regular 4ah and ran both max suction and extended run like it was a brand new vacuum. Buying another to fix up another used Dyson on marketplace to keep in the garage

## Questions & Answers

**Q: Dyson v8 for example runs on 21.6 volts, how does the dyson run on only 20 volts?**
A: Actually Dyson V8 batteries have 6 cells and are 21.6V nominal. DeWalt packs all have 5 cells x 3.6V in series and so are actually18V nominal, which many of their batteries actually say on the label. DeWalt just calls it a 20V system because fully charged it will actually hit 20V but then decrease about 2-3 volts as it discharges. (The 20V nameplate probably also helped them differentiate the newer lithium battery system from their much older 18V nicad system). At any rate, 18V is close enough to run the vacuum pretty well but one could assume about 15% slower motor speed. I would also think it would cause the vac's low battery warning light to come on sooner though, as that generally goes by pack voltage.

**Q: With this attachment the dyson v8 kept going, but the head got a bit hot, are their any problems with duty cycle of the dyson kept running?**
A: I haven’t had any issues with mine and been using it for at least 6 months

**Q: It works on light suction but it turns off after 3 seconds when i switch it to max suction ; what should I do?**
A: For this situation, we suggest that you should check your battery's electricity and capacity. The vacuum cleaners' usage totally depends on your battery's capacity. The adapter is just a converter, which won't cosume battery power or electricity.

**Q: Does it match a 18v dewalt 2.0ah dcb183 battery?**
A: Red light shows up when inserted with a 2AH Dewalt battery.  I assume that red light means low capacity although it still runs.  Green light shows up with a 5AH battery.  The fully charged Dyson battery has a blue LED light.  DeWalt batteries are heavier and can only be charged using a DeWalt charger.

### ⭐⭐⭐⭐⭐ Works Great! And There's Wall Mounts Out There for It!
*by L***E on December 8, 2025*

Works great with the 5Ah 20V batteries. The 2Ah 20V ones only like the low power setting. I'd still much rather deal with that than pay another $160 for a new Dyson battery. Also there's an Etsy seller that makes a mount for it for the wall holder!
