3V 1A 3W Adapter

Used to illuminate a shrine of a string of led lights. Runs day and night and it feels cool to the tact, an indication of minimal thermal losses. It met exactly what it was elected for.

I used it to my battery bug zapper that looks like a tenniss racket. I use a small garbage can lace aleft over peel ir fruir like cherry seeds on the bottom and place the zapper on top. True flies go by they smell the fruit they dive down hit the zapper and die better way than collecting them in a small jar of juice and see the nasty Critters this way here they just Sizzle away like you can't even see them they burn so bad so I used to trivolt plug modified it inside the battery compartment so it stays on constantly whenever elastic band around the button to keep it on otherwise I go through batteries everyday

Great AC adapter to connect to my holiday village street lights battery pack

I just recently learned the basics of circuits and transformers. This works perfectly with my dollhouse and lights about 20 little 3mm lights without any issues. My only complaint is theres a little blue light on it that is extremely bright.

what I dislike about 3V 1A Power Adapter Supply 3W AC/DC Adapter is that with only a 3W output, this adapter is not suitable for devices that require higher power, limiting its use to low-power electronics only. I may find the cord too short for their needs, which can limit flexibility in positioning the connected device relative to the power outlet. I have reported that the adapter’s build quality feels basic, with concerns about durability and longevity, especially if frequently plugged in and unplugged. Some adapters can generate noticeable heat during extended use, which could be a concern for those worried about potential overheating or safety issues. Lastly Depending on the model, the plug may not fit securely in all power sockets, leading to poor connections or accidental disconnections.

Funciona excelente

Worked perfect for a heat cool thermostat...

I like when I order something and it's exactly as it says it is. Perfect fit and a perfectly consistent 3V DC coming out of it.
