I bought this power supply for my iMM190 speaker. I hoped that it would save me from using batteries and possibly allow my old iPhone 4S to charge. This power supply works great. It powers the speaker and the phone charges. I use the speaker when I am on my exercise bike. Now I can just press the power button on the speaker and the phone lock screen lights up. I just have to swipe the lock screen and start the music app. This supply will pay for itself with the batteries it will save me not to mention the fact that I no longer have to take the phone off and charge it up.
