Ultrasonic cleaners

[Harry Klippton]

I've had a Vevor 2L ultrasonic cleaner for about a year and a half that saw regular light duty use but it recently stopped working. Unfortunately it's out of warranty, and despite being very responsive, Vevor customer support was ultimately unhelpful in diagnosing or repairing my unit. An ultrasonic cleaner is something I have a regular recurring use for and I've decided I can't live without one. While it's not very expensive, I'm not eager to buy another Vevor knowing that they're not very durable. So I have a few questions:

1. Is there a better option for a relatively inexpensive but more durable ultrasonic cleaner?

2. How does the transducer work? This is what stopped working. I looked for obvious faults like disconnected wires or broken solder joints. I don't know jack shit about transducers so are they high voltage or high current? I'm not going to go poking around with the unit on without know how to be careful around it


If necessary, I'll just replace it with the same unit again. It's not that expensive but I'd like to consider some options first

I mean. You gotta take it apart first.
If there's power getting to the transducer you can possibly just replace the transducer with Ali parts

I mean of course I took it apart but is there a way to test the transducer?

My no-name eBay one hasn’t died yet, but it doesn’t have a lot of hours on it.

I’ve seen real similar looking ones with a few different names on them, I’m betting most of the cheap ones all come out of the same factory.

I used to use a fancy industrial grade one at work, but I bet that was 10x the price of the generic eBay/ Amazon ones.

If mine dies I’ll just roll the dice again on whichever one is cheapest.

Sounds like a weak connection inside.
Reflow all the solder joints, and you're probably fixed.

I poked around and tested some components. Found at least one blown diode so I'll swap that and see where I'm at
