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)

Works with Dewalt 2Ah Max and 1.7 Ah Powerstack but vacuum pulses on and off with 5Ah Powerstack. Disappointed that it can’t be used with a higher capacity battery.

Works as described. Easy to install.

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 Quite a bit bummed, but gave it a try (in hopes the other reviews were outdated).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!

This product was very simply to install. As far as working correctly no. This product only works in the normal speed for the vacuum. When I go to max it runs for two seconds and shuts off. I tried freshly fully charged dewalt battery and it continued to do the same thing. Would not recommend this product.

I had the exact same problem as other users where the 20V 2ah battery didnt work longer than 10-20sec. I installed my 20v/60v 5ah battery and it worked fantastic. I assume a 20V with larger amp hour would work, but I only have an order small capacity 20V battery.

Product works great with the DeWalt batteries Ive used.

Perfect works great

Attached it to my Dyson v8…. blinked red and green lights and worked for a second then turned off. Doesn’t work.

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 love that this was an easy install and extended the run time significantly. We have 3 kids under 5 and 2 dogs, so our house is being vacuumed constantly, and this attachment has been a life saver. I do wish that the battery I have (v20 XR Lithium Ion) worked with the MAX setting on the vacuum. I only get about 2-3 seconds before it starts doing the stutter suction. Ive checked the inlet and changed the filters and still run into this problem.
