Does it matter what power adapter you use?
The general rule is to match the V and equal or beat the mAh, so if you are choosing an AC adapter to make sure you check the following, The adapter output V matches the rated input V of the device. The adapter output is greater or equal to the devices rated mAh or A.
What is A replacement AC adapter?
Alternatively known as an AC/DC adapter, AC converter or charger, an AC adapter is an external power supply used with devices that run on batteries or have no other power source. It then converts the power to DC that’s used by the computer, and a second cord that plugs into the computer.
What does a AC adapter do?
An AC adapter is an external power supply that converts alternating current (AC) from a wall outlet to a direct current (DC) needed by an electronic device. Therefore, it is an AC/DC converter. When it supplies power to a battery-powered device, it is also accurate to describe it as a charger.
Is it better to use a higher power adapter?
Usually, a higher power adapter will be more expensive, so if you have the option just match the device’s power. Your device is unlikely to operate if you have an adapter with a lower A or mAh output then the device, and if it does operate the adapter is likely to get very hot and could be dangerous.
What happens if you get your AC adapter wrong?
Getting it wrong can damage your equipment, the adapter, or both. The damage can be immediate, or it can appear over time. The specifications for your AC adapter (also not affectionately known as wall warts or power bricks) should be printed on the old one, and hopefully on the device too.
What happens if you grab an incompatible power adapter?
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. The worst-case scenario is that you burn down your house.
What should you know when replacing an AC adapter?
Incorrect polarity is the most common cause of damage when substituting adapters. Always assume you have to match polarity. Think of voltage as the speed of the electrical current. Electrical devices are designed to tolerate small deviations in voltage, but you should match voltage as closely as possible.
