Have you noticed the "500 WATT" mini amps on eBay? In most cases, these mini amps are under $20 US shipped. So, how can they make such a small amp so inexpensive and so powerful? Well, first of all, don't always believe output power specs unless more details are provided.
For example, the Kinter MA-150 has a big, silk-screened "500 Watts" on the heatsink. One might think since someone took the time to put such a rating on an amp, there would be some truth to it, right? Well, not necessarily...The MA-150 doesn't mention any RMS wattage output rating, so one is to assume the 500 watts.
Well, my friends, don't fool yourself! This $15 amp is NO 500 Watt amp. In fact, the most power I could squeeze out of it (with distortion galore) was about 30 watts. This was 30 Watts combining BOTH channels!

Watch the video to see the full measurements. I used my SMD DD-1 and Velleman HPS50 to measure everything from unloaded Voltage output to resistive loads from 8 ohms down to 2 ohms.

This entire video was made on my Apple iPhone 4 using the Apple earbuds with microphone. Video was edited entirely on the iPhone using iMovie for iOS. Amazingly powerful tool!!
