A replacement charger can look like a perfect match and still be the wrong choice. The connector may fit, the device may light up, and everything may seem fine until charging slows down, the charger gets unusually hot, or the device starts behaving like it has developed a personal grudge.

A few checks can reveal whether a charger matches the device, delivers power correctly, and carries legitimate certification. The trick involves looking beyond the plug and checking the details that actually matter.
