The answer is almost yes: I use a phone charger myself. A typical SMPS power supply does not support a digital negotiation. These then tell the phone the type of charger being used and how much current it can draw from it. Your phone does not recognize the power source and cuts back on the charge rate in the hope of preventing a catastrophic failure. The power adapter’s charges the laptop batter as well as you can directly run a laptop using direct power supply of power adapter if you don’t have a laptop battery or the battery is damaged.
