Review: Works for my hard drive and charging certain devices - This device works great. One thing I will note is that you want to set to the correct setting before charging or powering. Putting it on the wrong setting can seriously damage the device. I usually like to use this to power my drive as well as charging my bluetooth shower speakers. I has a hard time find a good charger. It also works for mg bigger battery packs. The brick does not getting any heat from what I can tell but it can if you put it on the wrong setting. The cable does feel a bit thin so handle with care. It does have six different tips that area easy to exchange. You just pull the tips out and exchange them for another. The setting can be adjusted with a coin or screw driver. Overall this is a great device to power things. I would recommend it to also make sure you have the correct settings before plugging anything in.
Review: Lifesaver! This Cord Is A Must-Have For Many Devices...Just Get It! - What a lifesaver! I lost the original cord to my only nebulizer (for asthma), a travel nebulizer. I had sudden onset, extremely severe asthma, and after an ER trip, I need to be able to continue treatments at home, and use it like I’m supposed to from now on. With no time to mess around, I took a chance and got this, and was lucky enough to have a same-day option (which saved me a hellish return trip to the ER, yea!). And yes, one of the plugs fits, and the correct voltage setting is one of the available options, and it works perfectly, of course. It will also fit loads of other things which no longer have their original cords as well. Thanks, guys! The same-day option was a figurative, maybe even literal lifesaver, and the driver even rolled up early (thanks, driver lady, wherever you are, you saved me money, and stress, and hours in ER, and you’ll probably never even read this nor be able to know that it was you, and how much you helped me today!), just as I was in the car backing out, and about to go back to the ER to get the asthma under control again until the cord would come at the scheduled time, just hours later. So kudos all around, it’s next to me right now, and I can finally safely go to sleep. You have no idea what a relief that is! 😅🙏💕

## Features

- 12W Power Supply Spec.: Input: AC 100-240V, 50-60Hz, DC output: 3V, 4.5V, 5V, 6V, 7.5V, 9V, or 12V 1.2A(1200mA Max), ✔️ Only for 3V-12V DC ≤1.2A Devices; Use the included key tool to securely dial in your required DC output; Warning: You must lock in the correct voltage before plugging the adapter into your device to prevent functional failure or damage;
- ⚡ NOT UNIVERSAL: This adapter provides a maximum output of 12W and 1.2A (1200mA). It works perfectly for devices requiring less than 1.2A (e.g., 500mA, 1A). ❌NOT COMPATIBLE with high-draw appliances requiring 2A, 3A, or higher (such as percussion massagers, cordless vacuums, or large Yamaha keyboards) 🛑 NOT A BATTERY CHARGER: This is an AC to DC power supply adapter. It will NOT charge batteries for cordless vacuums, rechargeable flashlights, or hover-boards
- 🔌 8 INTERCHANGEABLE TIPS (MEASURE FOR FIT): Includes 8 different right-angle connector plugs: 5.5*2.5mm, 4.8*1.7mm, 4.0*1.7mm, 3.5*1.35mm, 3.0*1.1mm, 2.5*0.7mm, 3.5mm Mono, and 5.0*2.1mm. ✅Crucial Step: Please measure the inner and outer diameter of your device's input port to ensure a secure physical fit. (Note: Not compatible with USB-C or Micro-USB ports)
- ⚠️ CRITICAL: CHECK DEVICE POLARITY BEFORE BUYING: This adapter is Center Positive (+) ONLY and the polarity is NOT reversible.🚫 Many devices (like electronic keyboards and guitar pedals) require a Center Negative (-) power supply. Using this adapter on a Center Negative device will not work and may cause damage. Please locate the polarity symbol on your device before purchasing
- ✅ SPACE-SAVING REPLACEMENT & SUPPORT: Replaces a drawer full of cords for low-power household electronics like LED light strips, wireless routers, electronic scales, and small fans. Backed by a 12-Month Warranty and 30-day return policy. Troubleshooting: If it fails to power your item, double-check that your device is Center Positive (+), requires 1.2A or less, and that the tip fits snugly
- 🔧 TROUBLESHOOTING GUIDE: If your device is not powering on, please verify the following: 1. Voltage: Is the dial locked to the exact DC output required by your device? 2. Polarity: Is your device strictly Center Positive (+)? (It will not work with center negative devices). 3. Amperage: Does your device require more than 1.2A? (If it requires 2A, 3A, etc., this 12W adapter is not powerful enough to run it)

## Questions & Answers

**Q: I have a 4 ft Gemmy indoor inflatable football player that needs a 12 watt charger.   Anyone know if this will work?**
A: Not 100% sure. List three points to help you distinguish if it's compatible...1.Polarity: inner positive2.Meet the working requirement of 12W charger, be aware that the maximum current is 1.2Amps. (If needed current exceeded 1.2A, please search: SoulBay 30W Charger.)3.Find the suitable adapter plug,6 Connection Tips Spec.: 2.5*0.7mm, 3.0*1.1mm, 3.5*1.35mm, 4.0*1.7mm, 5.0*2.1mm, 5.5*2.5mmBesides, Should you have the detailed sticker of your original adapter, please keep free to contact us at aruiservice@hotmail.comHope this helps you and best wishes!

**Q: i am looking for an adapter which would output 12v at .5A. Can this adapter do that?**
A: Hello Leno,Yes, it can. FYA, find a suitable adapter plugs for your device.Hope this helps you, have a nice day!

**Q: I have no idea what "inner positive" means, so how does one know if they have a device that is inner positive?  all the connection says is 4.5v dc....**
A: This can be tricky in some instance.. This unit has a (+) positive inner, and a (-) negative outside. Which means the female of the plug is positive, and the male ( outer metal) is negative. Now tricky part, some devices use outer ( positive "+") and (negative" -" ) inner. I ran into this with some light, and score board. I bought generic transformer on Amazon, and none worked. took apart light , and found the polarity was reversed. This is how OEM folks fool conservatives that don't buy OEM parts, or know how electricity works in dc circuits. (Had me confused for an hour or two)   OEM=  Original Equipment Mfg.

**Q: When using the 12 volt setting, what are the amps?**
A: I haven't used or tested the 12 Volt setting.  However excluding losses a IxV=W, so we can substitute and get I=W/V which in this case would be I=12/12, so theoretically the maximum current at 12 Volts would be 1 Amp.

### ⭐⭐⭐⭐ Works on some devices ..... not others
*by B***T on August 16, 2019*

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.
