Power Output by Voltage
Output power varies with supply voltage and speaker impedance:
12V: 12W + 12W (8Ω) | 20W + 20W (4Ω)
15V: 18W + 18W (8Ω) | 30W + 30W (4Ω)
19V: 32W + 32W (8Ω) | 45W + 45W (4Ω)
24V: 38W + 38W (8Ω) | 55W + 55W (4Ω)
Note: Sufficient audio input and power supply voltage/current are required for optimal output. Higher supply voltage increases power output; lower speaker impedance increases power but may reduce efficiency.
Absolutely brilliant product, I was expecting it to be slow giving the price but it's not, I would say it's an ideal starter phone for kids. Or even adults who just want a standard phone. You can download apps with it.
