Question 1

I have a 4 ft Gemmy indoor inflatable football player that needs a 12 watt charger.   Anyone know if this will work?

Accepted Answer

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!

Question 2

i am looking for an adapter which would output 12v at .5A. Can this adapter do that?

Accepted Answer

Hello Leno,Yes, it can. FYA, find a suitable adapter plugs for your device.Hope this helps you, have a nice day!

Question 3

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....

Accepted Answer

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.

Question 4

When using the 12 volt setting, what are the amps?

Accepted Answer

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.
