Belker 36W 3V 4.5V 5V 6V 7.5V 9V 12V Adjustable Voltage Universal AC/DC Adapter Power Supply for Household Electronics Security Camera Router LED Strip Light Keyboard Tablet - 3A 3000mA Max.

Works great and I love that it has many connectors for multiple electronics to charge also great price

We had purchased "Motion Sensor" stair lights for a dark staircase. They worked great, always came on, and shut off after a few seconds.After the first two weeks, they started to dim, and required 4) new AAA batteries EACH. I bought the "Ultimate Lithium" batteries, and they also died before three weeks of use. We were spending just under $60.00 a MONTH, just for some light on the stairs.I opened the lights up, re-wired the battery leads, and soldered on wire extensions. I connected the BELKER adapter, set it to 6 Volts, and plugged it in. Problem Solved! I fished the new wiring behind the stairs, and installed the Power Adapter in the basement ceiling. No more giant battery orders, and all the lamps are all bright. (FOREVER)

If the VA .let's your needs. It is the perfect DC power supply to put on the shelf. The adjustment for DC voltage fits most applications. I would buy again.

I looked at a few different universal DC converters and my biggest concern was how easy the voltage dials would be to accidentally turn. You might think you want a nice easy dial, but if the dial is too easy to turn it could be turned by accident. If you have a 5V device and the dial gets bumped to 12V, your device is likely to puff out some nice smoke.This one requires a flat object (it comes with a "key") to turn the dial. The dial is just hard enough to turn that I is unlikely to get turned by accident, but not so hard to turn that it would be a pain to change.

Was not too sure how well this variable power supply would work, but took a chance as the original power supply replacement was about the same price and hoped this would actually work for several of my devices.Easy to set: Just use small screw driver to set the dial to device voltage.Charged the battery for two different devices so far, and confident it will also work well with the restof my other devices missing their original charger.Excellent device, good price, and eliminates needing several different power supplies.

Excellent product, would recomend.

Ordered this Belker 36W AC/DC power adapter, and...there was NO adapter in the box! Just the DC barrel plugs and their mounting strips. No actual power adapter, AT ALL. Tough to give this product any rating for Vesatility, Value for Money, or Easy to Use when....the product is NOT IN THE BOX!

This would be perfect for my needs if it limited draw to 3A and let voltage drop after, but instead it triggers overcurrent protection and resets the circuit over and over.
