power supply/transformer output blurred or blank
I'm looking to buy a power supply/transformer that plugs into AC with 9VAC 1,300mA output. On all the listings, the output in the photos is blurred or missing - intentionally made to be blank. It's important to match the output whether it be 9VAC or 9VDC and the amperage. I won't buy unless I can match this as it could damage the device. Why on all of the images is this blurred or blank ?

·3 years agoMy guess is that these sellers are using stock photos, and they don't match the actual item. Refer to the Item Specifics, where the voltages should be correctly specified. You may also need to specify a regulated supply if your device allows a very limited voltage swing (a 9V +/- 10% type of rating), unlike a dimmable lamp.
Also note that the mA stated on the supply is the max power that is available from the supply. It is quite acceptable to get a larger supply than you need (like 3000ma), but a smaller supply won't sufficiently power your device. Just make sure the voltage is within range for your device. If you receive an item where the specs on the label do not match the item specifics, open a return for "not as described".
If you have a voltmeter, check the supply before connecting your device, to see if you are getting the AC voltage you need and to make sure the polarity is correct for your application.

OP3 years agoThanx for your reply. It wasn't one picture that was blurred and shown many times. All pictures were blurred and some were blank after "Output" as if intentionally photoshopped out. The description did not have the output listed in many of these posted items and some put just "DC" for the output where is was like to not be DC but AC. It appears that they all deleted this info in different ways and kept the info concealed. I'm an engineer and understand. It's for a 9VAC 1.3A output for a guitar looping pedal - low power. For the seller, they may sell the wrong power supply and be happy with the sale as small items are rarely returned, but this make it impossible to buy the correct power supply. I'm not going to buy the device to then test it later when I could have simply read the numbers from the image and avoided buying the obviously wrong device. How can this be fixed so power supplies have their output voltage listed or shown on an image. HOW CAN I GET EBAY INVOLVED TO FIX THIS PROBLEM?

Do you have any item numbers to share? Perhaps the category itself addresses the question. If one is selling power supplies, a power rating is essential to selecting the correct module. I don't know why a seller would intentionally mask the ratings, and then fail to specify the actual power ratings. As we all know, products can blow up or burn out when power is misapplied, so those listings could represent a safety hazard.
I can only suggest avoiding these sellers. But that does leave other buyers at risk.
@devon@ebay Do you have any recommendations for addressing this type of issue? Not all buyers are engineers who grasp the significance of improper power application. Does this violate any eBay rules or safety laws?

Hey @shipscript! Just as you suggested if their are item numbers that can be provided we can take a look into this scenario. In general all listings and descriptions should be as accurate as possible and I can reach out to see if there would be any other safety violations for these types of listings.

Thank you for providing that list. Four of the items specify a product match, rather than giving specific details, although they all say AC-DC adapter, which means DC output. The generic one not matching any specific product, does state the output in the description as DC 9V 2A.
I started an AC-AC adapter search in Musical Gear.
While a lot of AC/DC adapters were displayed, these three came up as AC-AC. They are all the same brick:

OP3 years agoThanx again for your help. I hope you got my point that the important information was concealed and shouldn't be. There are many many many other listings like this. I was able to find a power supply that will work (that I'll buy if I win my auction tomorrow), so I'm not looking for help buying a product. It took me a long time to work through so many listings without the output power specs listed. I would like to see this fixed, meaning output power specs should be clearly listed and correct or shown in the product image.

I've looked at the listings provided by the OP. While a power supply could name a product (or several) that it will work with, power supplies (somewhat like batteries) are essentially generic (and often interchangeable), based on their power, electrical ratings, and protection circuits, and on the configuration of the input plug and output tip.
Like the OP, the above are features I would look for when shopping for a power supply, and these specs are missing from listings.
Naming a matching product may help a non-technical buyer with that match, but it also allows flooding search with "works with" scenarios for identical products. The only reasons I can imagine these sellers have eradicated the output data is because they don't want to show that the same converter is appearing in other "works with" listings, or because it is easier to promote an entire product range with a single stock photo. A look at "seller's other items" could tell volumes. Nonetheless, important decision-making info is missing.
The four listings that name a matching product are missing the output specs and tip type. Several even say "Please make sure the output and tip size are correct before use", and they don't even put that spec in their listings. {{Rolling eyes here}}
The single generic listing includes the expected specs, including the tip type, polarity, and dimensions (they come in different sizes), although the AC blades of the wall-brick are not clearly shown:
CE Certified.
OVP OCP SCP Protection.
Input voltage: AC 100-240Volt 50-60Hz (world wide).
Output: DC 9V 2A
Connector size: 5.5mmx2.5mm Center Positive
Cable Length: 4ft.
So, I think the issue here is that the information necessary to select the correct product is intentionally missing from a significant number of listings searched by the OP, resulting in a poor buyer experience.
