Belker 12W Universal 3V 4.5V 5V 6V 7.5V 9V 12V AC DC Adapter Power Supply for Household Electronics - Max. 1000mA

I have a blood pressure monitor that just EATS batteries. It, fortunately, also accepts AC power. However, after just a couple of years, I noticed the wire leading into the jack to the device was breaking and before I could figure out what happened, one side of the dual-wire broke entirely.This, with the multiple plugs available and the multiple settings for output power was just what I needed. Once I was able to see the symbol for the power requirements of the port (TINY printing), I chose this device as a replacement.I wasn't sure which of the two largest ports to use as both seemed to fit. I chose the 2nd largest, fearing the other might be too tight and get stuck in! It worked fine!I'm now able to bypass expensive AAA batteries and can use this elsewhere if needed.The only negative (and that is not worth a decrease in stars) is that the wire is flat 2-part. I feel that if it were round, it would be stronger and last longer.

This AC to DC adaptor power supply works well with my PT-1 Pink Triangle turntable with a DC motor. I use the 9V setting.

This work very well.

This adapter was bought to replace one that just stoped working. It saved me so much time because it had so many adapters included.

I needed a replacement charger for a small skincare device. The original charger is available from the manufacturer for $20 plus shipping, so I decided to try this one instead. On the device there are no markings to indicate what voltage it requires, so I figured I could simply start out by selecting the lowest voltage (3 volts) and increase it if it didn’t start charging. Fortunately, this charger includes most popular plug sizes and I easily found the one that fits my device and the 3 volt setting did work as soon as I plugged it in. I’ll keep those extra assorted plugs handy so I can use this charger on other devices if I need to. Great flexibility and very good value!

Great price and a great idea !!

Works with some items but not with others. Not real impressed so far but cheap enough. Decided not worth returning.

Works well on a 20-year old scoreboard unit.
