Review on 🔊 Nobsound NS-15G PRO 2 Channel Bluetooth 5.0 Amplifier - Class D Stereo Audio Power Amp Receiver, 200W by Digna Rodriguez

No matter what the real power output is or how they get it, the Chinese company Douk Audio really tries to make and maintain a quality product! This little jerk has it all. I use it with a pair of Klipsch R51M speakers. Wow! Impressive, dook, impressive. However, please update your declarations of performance and explain to people how it works. Please also offer a full 24V 5A power supply along with a lower power supply. The 3116D chip is rated at 100W at 4 ohms at 24V, 5A. There are 2 of them in this device. The device comes with a 19V/4.75A power adapter that has a maximum output of 90W. Since no power supply is 100% efficient and these little devices are unlikely to exceed 85% efficiency, the total power output is 76W. Additionally, the Texas Instruments 3116D amplifier chip has an output power of 100 watts into 4 ohms when using a 24V, 5 A. Can you get 200 watts out of this amp? How does an amplifier increase output power?
