V8 Battery Adapter for Dewalt 20V Lithium Battery Converted to Replace for Dyson V8 Battery, Works with Dyson V8 Series Animal Absolute Vacuum Cleaner(DW20V8 Adapter ONLY)

I was really excited for this product. It has great power and last long time, but you can’t put it on the high setting. So you’re forced to vacuum up a low setting everywhere. Sent it back. I got an actual battery replacement and it works fabulous. You can’t vacuum without the high setting.

Perfect works great

It fits perfectly, but as others said it will not work on the max setting. Thats a deal breaker for me, so Im sending it back. Quite a bit bummed, but gave it a try (in hopes the other reviews were outdated). This is as of 14 February 2023. Good luck!

i had to come back to this page to figure out how to swap the battery adapters. There are 3 screws total, 2 are hidden. Other than the setup, this thing is incredible!!!!

My Dyson V8 and DW battery are good but not working when pluged into this adaptor, so Im sure this adaptor is a fail !

I ideally wanted to use this with the maximum suction function but the light turns red after a few seconds. On the lower setting it works fine. Buy this if you dont mind the lower setting.

This works well with 4 ah Dewalt batteries in my Dyson V8. My initial impression is around 25% more life than the original battery. This does NOT work on max setting with a smaller, 1.5 ah battery. If you use max settings and have the smaller Dewalt batteries then Id avoid this. Otherwise Im looking forward to having swappable batteries for my Dyson! Id give it 5 stars but the seller should indicate the need for larger batteries.

Plastic around the trigger broke off and unit snapped apart within 4 months.

I have 2aH and 5aH batteries and this adapter fits both and allows extended run-time on my V8. It works on Max Suction or normal suction. I have not tried my 60V DeWalt batteries. Good buy if youre already invested in the DeWalt system.

These adapters only work on the low power setting. I tried it on 2 different fully operational dyson v8 vacuums and neither worked so I figured I just got a defective one and switched out a replacement, but had the same result with the replacement, so these just dont work on max power.
