I don't know how this vacuum cleaner model works: MZ-5234 will work because "DC 8.4V output" is printed on the USB connector. I'll plug it into my USB port and see how well it works, then I'll update the review. The vacuum cleaner is well packaged and looks high quality, time will tell. The stainless steel filter is one of the reasons I bought this vacuum as it can be cleaned many times. UPDATE 08/31/21 I was able to charge my vacuum cleaner with a standard USB charging adapter. We have used a vacuum in our RV and are happy with the results. When you first turn it on you might think the suction power is poor, but with or without the attachments it sucks well. It fits perfectly in one of our drawers and is a nice addition to a camper van.
