3-12Vdc Switching Power Supply

This is a good option for hobbies or if you lose that pesky little power supply for a toy or device. The switching voltage and different adapters really help. The only other feature I wish it had is a polarity switch. On a few electronics the positive and negative are reversed on the post vs sleeve. Be sure to check your device before plugging it in. Just because it fits you may have one of the rare devices with opposite polarity.

Works well, good asst of plugs. I keep buying these, even when I don't need them and they are stacking up.

Didn’t work for the litter-robot that I bought it for. One of the adapters broke after using it once.
