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.

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

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

This is a decent little supply for the price. But be aware, the cable is painfully short. It appears to be about 3-feet in length, and this is too short to reach from my desk to the power strip on the floor.

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

Mine had horrendous RF noise, if you’re buying this for an AM radio you might shouldn’t. The cord is only about 2 foot long too.

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.

As someone who repairs retro video game systems, sometimes it's hard to find OEM replacement NES AC adapters so I'm always on the lookout for something to take their place. It makes it easy when I can easily and affordably find an adapter with matching specs for under $10. Even better when the form factor is small enough to not take the space of 2-3 other nearby outlets, unlike the original NES adapter. This one does the job perfectly. The indicator LED is a nice addition as well. I know they make cheapy aftermarker NES/SNES/"Genesis" adapters but they feel very cheaply made, are as large as the OEM, and don't have a cool indicator light like this one. This will likely turn into my go-to replacement for NES adapters from here on out.
