## 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.
