Over the years that you’ve owned laptops, smartphones, tablets, speakers, and other portable electronic devices, you have probably accumulated a number of electrical adapters, and may even have kept them for potential use on a replacement device. This can be dangerous. Most portable devices have specific types of batteries that require very specific power input. Incompatible pairings can cause severe damage, as well as render a device’s warranty null and void. Each adapter delivers a precise amount of electricity from a standard 120 volt AC wall plug by calibrating the electricity so it is compatible with the lower voltage DC batteries within the specified device it is designed to power. An improper match could cause hazardous overheating or frustrating underperformance, compromising delicate circuitry. For this reason, it’s risky to presume that older adapters with matching fittings are actually safe for your device, especially if you’re travelling to countries with different electrical systems. Fortunately, newer adapters that use USB connections tend to have a broader range of compatibility, although you should always follow manufacturers’ guidelines before usage.
