Belker 36W Universal 3V 4.5V 5V 6V 7.5V 9V 12V AC DC Adapter with 8 Tips

Works as described. durable cord. Adapters are all for center positive. Mini USB adapter included. Wire terminal adapter included, + and - terminals.

Using these for LED Lego lighting displays. They work great. I like that the voltage setting is on the plug side so it is less likely to get switched after the fact.

Purchased a Famicom without a power supply. Needed a 7.6 volt DC supply which is not a common voltage. First we purchased a different brand of dedicated 7.5 volt supply but when we checked it before use we discovered that the output was 8.5 volts, with or without a load applied (measured with a Fluke meter in good operating condition). We rejected that supply and decided to try the "Belker" listed here.. I am happy to report that the Belker supply, when set to 7.5 volts, was measured to be providing 7.6 volts. While that is 0.1 volts over the rating, I consider that to be a negligible error. And since the Famicom is rated at 7.6 volts, this small error actually made it a perfect fit. However, even at the rated 7.5 volts, I feel confident the Famicom would still be happy. So if you have a Famocom, this should get you going. HOWEVER: Never trust a power supply out of the box - manufacturing errors are common - wrong polarity, wrong voltage. It only takes a moment with a meter to verify these things before use. The gadget you save may be your own! Hope this helps. Have fun.

This power adapter "Belker 36W Universal 3V 4.5V 5V 6V 7.5V 9V 12V AC DC Adapter Power Supply for LCD LED Light Strip Router HUB Speaker Smart Phone TV Box 1A 1.5A 2A 2.5A 3A 3000mA Amp Max" comes as listed. It appears to work as listed. Settings for voltages match. Haven't tested amperage rating but I understand amperage should be kept at around 75% of maximum. Voltages measured run a bit high but less than +10% of the listed voltages (+5% to +9%) but without a load. As a load increases I understand I should normally expect a little voltage sag so this is not critical. Overall appears to be good good quality with no excess packaging.

A nice voltage adapter... I let it run for a few hours and checked all of the various voltage outputs with my digital multi-meter and they are all mostly within spec. If anything they are just a tad over voltage but it is so minuscule it's not a concern at all. Brand new batteries are a tad over too so the amount that is over spec is of no worries at all. The voltage readouts were all very stable too with no drift either way. The voltage adapter can handle many devices with the use of the included adapter plugs. My particular need was the 5.5x2.5 mm size for my Christmas nativity which I overhauled and installed new LED lighting in it and installed a 5.5x2.5 mm female panel mount jack and a rocker type on/off switch to turn the lights on and off. Very fast shipping on the adapter too. I received it in two days. Thank you!

My Kindle charger finally quit. I got good service from it. This Belker charger works great for my Kindle charging fast, and even while charging the Kindle works MUCH faster and better than when the battery gets below 12%. To increase the battery life time, I wait to recharge until I'm below 10%. The original 2013 battery is STILL doing great, and I use my kindle HD several times a day for about 30+ minutes. The many accessory tips will probably make it useful for other devices.

I bought the Belker 36W Universal Adapter Power Supply for my Foxelli trail camera and it's been working great for a couple of months now. For the price of a package of batteries, I now have an unlimited power supply for as long as I choose to keep my camera within reach of a power cord and outlet. I plug/unplug the adapter end every day to bring the camera inside in order to download the photos to the computer. The adapter still fits snugly and hasn't broken or worn out. The 3-prong plug end is protected from the rain and direct sunlight, but it is subjected to drastic changes in humidity and temperature, which have not fazed it at all. I'm well pleased.

Not compact Not compatible with recessed connectors Not easy to use Not good value There, I satisfied the AWS AI. This is a bad product. I'm sure if you need something, you can find something better than Belker. I thought it was BELKIN. Jeez, I would never buy this thing again. It's terrible!

I bought this to work with my portable blood pressure measuring device. Though I select the right output voltage it still didn't work!
