## Description

* This item is just a converter adapter, not a battery or charger, and no battery is included in the package; * Why you meet that the vacuum cleaners turn off after few seconds? Or say only works on low setting but cannot work on max setting? Please let me explain the situation. In fact, the dyson v8 vacuum cleaners have a protection voltage. And the battery also has a protective function. Once you switch the vacuum to a high mode, the battery cell's discharge rate is low, it will stop automatically in order to protect them. So when you use the low setting mode, it works normally. And our adapter is just a converter, it does not consume any energy. So the machine's work depends entirely on the battery. For this situation, we recommend that you'd better to use a new and high capacity battery. * For Dewalt To Dyson V8 Battery Adapter Compatible with DeWalt 20V 60V Battery Note: 1.The adapter is incompatible with Dewalt PowerStack batteries; 2.Compatible with Dyson V8 series vacuum cleaners, not for V6 V10 V11 V12 V15; 3.Only 4Ah capacity or above can run V8 vacuums cleaner; 4.Must fully charged the de*walt battery before using it to run vacuums; 5. Only Adapter included in the package, no battery; 6. This is an converter adapter, NOT Battery, Not Charger.

Review: Easy to assemble and works great
Review: Fits perfectly and now the Dyson lasts 30 minutes instead of 2. I’ve got loads of dewalt batteries so I just swap them out when they are out of charge. Highly recommended to improve your Dyson.

## 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.

*by V***R on 19 November 2023*

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!
