UBEC DC/DC Step-Down (Buck) Converter - 5V @ 3A output
https://www.adafruit.com/product/1385
Adafruit order number 2842447-1402830870
Purchased on May 8, 2022.
I connected 12.3 V to the input of the UBEC with no load other than a multimeter. The UBEC immediately popped, got very hot, and had a swinging output up to 200 V.
Setting aside wasting a bunch of time this is an irresponsibly dangerous product to sell without QC and a total ripoff at $10.

Re: Defective UBEC
Can you post a photo and indicate which side you connected the 12v input on?
As long as you connected the input on the correct side we can refund you for your purchase.

Re: Defective UBEC
In lieu of any markings on the UBEC and difficulty finding useful information on the store page, I worked with the assumption that the filtering cap would be riding the output.
Afterwards I found this buried on the store page:

Please label the input on the UBEC and more clearly label this information on the store page.The IN side (provide 7V-12V) is the open wires and the out (supplies 5V) is the black 3 pin female connector.
