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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works Flawlessly for me *by on Reviewed in the United States April 9, 2026* I like finding practical solutions that extend the life of tools I already own, so I was genuinely interested to see how well this JJXNDO V8 adapter would perform in real-world use. After testing it with my Dyson V8, I can say it’s a clever idea that—mostly—delivers when used correctly.The concept is simple: this adapter allows you to use a DeWalt 20V lithium battery in place of the original Dyson V8 battery. Installation was straightforward and didn’t require any modifications to the vacuum or battery. It clicks into place securely, and removing it is just as easy.In terms of performance, the biggest advantage is runtime. With a higher-capacity DeWalt battery, I was able to clean longer without needing to recharge, which is a noticeable upgrade over the stock Dyson battery—especially if your original battery has started to degrade over time.Build quality is better than expected for an accessory like this. The plastic housing feels solid, and the connection points align well without looseness or wobble. Once attached, it feels stable during normal vacuum use.A few things stood out during testing:* Great way to repurpose existing DeWalt batteries if you already own them* Extended runtime compared to an aging OEM battery* No tools required for installation* Fits snugly without interrupting normal operationThat said, there are a couple of important considerations. This adapter adds some bulk and weight to the vacuum, which can make it feel a bit less balanced, especially during longer cleaning sessions. Also, since this isn’t an official Dyson accessory, there’s no onboard communication with the vacuum for battery percentage, so you’re relying on the battery’s indicator instead.One more practical note: as with any third-party power solution, it’s important to use quality batteries and avoid over-discharging to maintain both safety and longevity.Overall, this is a smart, cost-effective workaround for extending the usability of a Dyson V8—particularly if your original battery isn’t holding a charge anymore. It’s not a perfect plug-and-play replacement, but for the right user, it’s a very functional and worthwhile upgrade.A thoughtful accessory that solves a real problem without overcomplicating things. ### ⭐⭐⭐⭐⭐ should have bought this sooner. *by on Reviewed in the United States July 7, 2026* very clear instructions. easy to install. the vacuum works 10x longer than with the original battery. ### ⭐⭐⭐⭐⭐ DOES NOT WORK WITH POWERSTACK 5AH *by on Reviewed in the United States September 3, 2023* 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.
