9VDC 1A Arduino Compatible Power Supply Adapter 110V AC 5.5 x 2.1mm Tip Positive Part#LJH -186

This is a great product and great price.it also has a little red light that tells you it is working.it powers up my stop barking devise.it has been doing a great jod for over 3 years.

arrived quickly. just the right size and voltage. needed it to power chicken coop door in case solar didnt work

Ordered this power supply for an inhouse project, was going to use it as intended, however upon closer inspection, it was discovered it could be easily opened. The circuits were very well built and allowed for easy access to the primary solder joints which allowed us to connect to the projects main power inputs thus eliminating a second outlet. SO for someone whos looking to embed an Arduino or Pi into a larger project, this wall wort can be easily incorporated into a larger power management lay out

The cord is 42", something to consider

Does what it says it will do. No issues yet. Will update the review if/when it ever fails.

This is not the standard power plug size, will not fit over the center pin on the router I wanted to use it on. I was able to drill it out to get the router going, but the plug wont stay in now, so not a good solution. Check the size carefully to be sure it works with the device your going to use it on.The radio interference caused by this adapter is unacceptable. It's effecting AM radio all over the house. If this is an issue for you, avoid this adapter.

What we liked about the 9v1A Arduino Compatible Power Supply Adapter! Had, ordered it on line, was hoping it would be delivered before Christmas! 2020 was not a very good year so! so when we pulled out all the Christmas Decorations, from the garage, I, was very disappointed! ( Singing and dancing Santa Clause), the original power supply was missing! The Singing Santa clause, was not able to sing or dance! with out the power adapter, which Santa sings over 9 Christmas Carols!, was purchased over 20 years ago! It, would not seem the Same with out this long time Family Tradition IThe 9v1A Arduino Compatible Power Supply Adapter, was delivered a day before Christmas Eve! Santas voice sounds a little deeper,but it works good! So, it definitely cheered up our Christmas Season! Holiday!Thank You!

This is a DC 9V 1A Power Adapter. The NES *should* be using an AC adapter, but it works great and adds no noise to the audio/video out. Only thing bad about it is the big LED on it. Just used some duct tape to cover it and it's great now.
