Variable DC Power Supply 3.6-24V 2.5A Power Supply with 5.5MM x 2.1MM Plug, Includes 5.5MM x 2.5MM Plug Adapter

This power supply works perfectly for my needs. The 1A spec. is really helpful. The two sizes of plug are also a plus.

I had to return this adaptor due to polarity. I needed a negative center and this one is positive. My bad! But the return was handled quickly and no problems whatsoever. Thanks guys! 👍🏻

So... If you like your electronics to get power, then this is the adapter for you! If, on the other hand, you have mixed to negative feelings towards blinding blue LED power indicators that can literally light up a room at night---especially if it's in a room you're trying to sleep in---maybe this isn't the adapter for you. You WILL have to dig out your roll of electrical tape to cover up the LED. This review would have absolutely been a 5 star rating were it not for that.

I needed a 9V DC 1 amp power supply for an Arduino board and this worked perfectly.

Works great till it rains. They are not water tight..Shorts out and quits working after first rain..cheap crap.

Ordered this to power a small portable fan instead of using 2 D batteries. Worked great and the included extension cord was a big bonus.

I used this for a Dermlite DL3 dermatoscope. It worked fine and was much cheaper than the a replacement charger for dermlite.

The variable tips are easy to attach and the voltage selections simple to mchange with the included wrench. The good selection of tips adds top the versatility. Good value.
