9V 3A 27W DC Power Supply Adapter Power Cord Charger for Schwinn Exercise Bike or Arduino UNO R3, for Crosley Cruiser CR8005A, for Elliptical Trainer【NOT for Pedal】

Works great for my raspberry pi.

Very useful

as described

I modified a battery powered labelmaker to run off a standard 120v wall receptacle using a 5.5 x 2.1mm barrel style male electrical connector and this 120v to 9vdc wall transformer with a matching female end connector. No more searching for batteries. The picts show what the transformer is used for.

I needed to replace adapters for two dehumidifiers. I accidentally ordered the wrong adapters with a higher amperage. Luckily my husband noticed the problem and I easily reordered these adapters and they are working perfectly.

I bought this as a replacement for a power supply that began to exhibit brief but frequent 12v spikes, which caused the powered equipment to glitch. At first, this supply worked fine, but 4 weeks later it intermittently goes into a state where output voltage drops to wavering between 4 and 7 volts.Another example of complete Chinese garbage.

Great replacement.

Tried other transformers for my closet dehudifier, Other ones had enough voltage, but not enough amperage to run the small motor. This one works! The plug also fits the Jese brand model JS-904 . Has not yet proven the test of time, I just received it.
