SoulBay 12W Universal Multi Voltage AC/DC Adapter Switching Power Supply with 8 Selectable Adapter Plugs, Suitable for 3 V to 12 V Device

Love it !!! Works great, my daughters enjoy playing piano again !!!!

I pisplaced a charging cord, for a cardboard ripper, and with this set of adapters it's now charging for the 1st time "thank you"

We did some interior remodeling of the house and lost the AC plus to the OttLite Model T3 LED 5W 5V 1A. This looked like the solution. The first unit came with a RadioShack AC plug no orange colored voltage adjuster. Returned and prompt replacement (no charges). Easy to use. Key to adjust voltage, OK lots of plugs. Found one that seemed to fit, but the OttLight would not turn on. Sometimes there was electricity and the light would flicker but for the most part it didn't work. Other plugs would not fit, either too small or to big. So as a test I connected the adapter to a Tripp-Lite UBS hub (5V 4A) and it worked fine. Both the OttLite and TRIPP-Lite have the same (+) polarity. Make sure the clarity of what you have is correct. Also make sure the green light on the AC block is green, I had an extension cord that I plugged into and it didn't work because of a bad connection. Of note the plugs for the device have one pin that is thicker than the other so be aware and not push too hard, the size difference is not so apparent. The other aspect, which may or not be an important factor is that the lugs to the device are a 90 degree angle. Overall- it didn't work for my main purpose (OttLite) but can work (USB Hub test). Easy to use. Good value for money if it works.

Works on almost everything that has a pin for charging. A game changer for real.

Multiple uses decent tranformer

The pictures for this item shows a product with much better build quality than what actually arrives. The pins on what I received were hollow and of a material that was thin enough to get deformed when I pushed the adapter plug I intended to use into the holes on the cable end. The picture in the description appears to show solid pins. The cable end has a fork like insert that is intended to squeeze on opposing sides of the pins, whereas the picture in the description clearly shows a solid ring that would hold onto the pins. The plastic on the cable end is very soft (this would be hard to discern from the pictures) and I fear that this, in combination with the fork like insert, will over time make for a very unreliable connection. I will likely return this power supply with the comment that it was not as advertised.

I, like others checked voltage on setting with DVM, and all were +/- .006.. (All in correction range). Only negative thing I could say is the cord is pretty short. Would be nice if it were another 24". Now I haven't hooked this up to a load, so not sure how long it will last. I bought it to retrofit a 4.5v game sign that has led tubing. Bought at Bed Bath & Beyond, but it only works with (3) 1.5v batteries (in series). I bought some dc volt jacks here on Amazon, and I'm going to wire to run off this transformer.Will update when hooked up. BTW. People saying to attach the so call key to cord so you won't loose.. The key is for a slotted screw driver slot for selector switch.... ??????Will Update you with final results.. Update: Just hooked this to the LED sign, and transformer hums with a load on it. Checked on several dc items, hums on them all.. Not a loud hum, but something that can irritate you.. You no, when you search a room looking for that slight humming / buzzing sound.....

This is amazing when you lose your plug for anything that has to be recharged. Everything you possibly need for multi-purpose use
