Im willing to bet that any given household has a dozen or more of different types of cell phone chargers, ACDC adapters, power bricks, power cables, and charger plugs. Its easy to get them separated from the phone or laptop or tablet or router. And once that happens, it can be incredibly difficult to figure out which goes with which. The default solution to this is to try random plugs until you find one that fits into your device. If you grab an incompatible power adapter, your best case scenario is that it works, albeit not the way the manufacturer intended. The second worst case scenario is that you fry the gadget you are trying to power up. In this article, Im going to walk you through the process of digging through your junk drawer and finding the right power adapter for your device. In a nutshell: The following will cause damage to your device: Reverse polarity Higher voltage adapter than device rating The following will cause harm to your power cord or adapter: Reverse polarity Lower current adapter than device rating The following might not cause damage, but the device will not work properly: Lower voltage adapter than device rating Higher current adapter than device rating A Very Brief Introduction to Electrical Terminology Each ACDC power adapter is specifically designed to accept a certain AC input (usually the standard output from a 120 V AC outlet in your home) and convert it to a particular DC output. Likewise, each electronic device is specifically designed to accept a certain DC input. The key is to match the DC output of the adapter to the DC input of your device. Determining the outputs and inputs of your adapters and devices is the hard part. And if there is no information on the label, proceed with extreme caution. The most important details for you and your delicate electronics are the voltage and the current. Voltage is measured in volts (V) and current is measured in amps (A). Youve probably also heard about resistance (), but this doesnt usually show up on power adapters.) To understand what these three terms mean, it helps to think of electricity as water flowing through a pipe. ![]() ![]() Too much power generates excess heat, which is the bane of sensitive electronics. For direct currents, there is a positive pole () and a negative pole (-). For an adapter to work, the positive plug must mate with a negative receptacle or vice versa. Direct current, by nature, is a one-way street, and things just wont work if you try to go up the downspout. If you multiply the voltage by the current, you get the wattage. But the number of watts alone wont tell you if the adapter is right for your device.
