An AC adapter supplying electricity at a higher voltage than required will cause the connected device to run hotter. Using an adapter with a higher voltage will cause the connected device to detect an overvoltage. This happens if the adapter’s VDC is lower than the device’s input voltage even when their current ratings are the same.

#AC DC ADAPTER HOW TO#

Shoppers learning how to choose AC adapter should know that most power adapters have output DC voltages below 20V while their input AC voltages are over 100V.Ĭhoosing an adapter with a higher or lower voltage or current rating may cause the connected device to malfunction.

#AC DC ADAPTER MANUAL#

Check the device’s product label or user manual to see its rated voltage and current. The device’s input voltage and current must match the adapter’s output voltage and current. The right AC adapter for your device is one with matching electrical ratings. The DC voltage is the output voltage of the adapter, and it is usually much lower than the input AC voltage. The AC symbol is a wave, while the DC symbol is a solid dash with three short dashes underneath it. When reading an adapter label, the VDC will be under the DC symbol.

The DC voltage (VDC) of the power accessory is as important as its AC voltage (VAC). These are most useful for travelers researching how to choose the right power adapter that will work in other parts of the world. Dual voltage adapters have listed input AC voltage ranges of 110 - 220VAC or 100 - 240VAC. To make it easier for users to choose an AC adapter, manufacturers usually offer adapters that support both voltages. Depending on the region, AC input can be 110/120V or 220/240V. Power adapters have AC inputs and DC outputs. The unit for voltage is volt (V), while current ratings end in amps or ampere (A). However, polarity is also an important factor. The most important sections to read on a power adapter label are voltage and current. Alternatively, check the device’s user manual for the electrical ratings of its AC adapter. Manufacturers usually print such information on the labels of these power accessories. When learning how to choose an AC adapter, it is also necessary to understand power adapter specifications. The first step is to determine the electrical rating of the device. Therefore, finding the right AC adapter for your electronics requires selecting a compatible third-party accessory. In some cases, OEM adapters are no longer available from manufacturers. Find the specific adapter for the device by searching for it using the model number printed on the adapter shipped with the device.

Determining how to choose the right power adapter for a device becomes easy if this OEM accessory is available. Device manufacturers sometimes offer replacement chargers/adapters for their products. Users do not have to throw away their devices if voltage spikes, or in the case of brownouts or electrical fires destroy their external power supply units.īefore trying to find a matching AC adapter for a device, check if the OEM (original equipment manufacturer) adapter is available. Lastly, external power adapters are easier to replace. This design also reduces electrical noise and improves safety.Ī manufacturer can also support a wide voltage range by choosing an external power supply when designing the right AC adapter for your device. Having a separate and external AC/DC power adapter also reduces the heat produced inside an electronic device. Those researching how to choose the right AC adapter should know that devices with external power adapters are lighter than those with integrated AC adapters. Installing the power components of devices in external AC adapters allows manufacturers to make them smaller.

#AC DC ADAPTER PORTABLE#

Before picking the right AC adapter for your device, it is useful to know the reasons most portable electronics use external power adapters.

When it supplies power to a battery-powered device, it is also accurate to describe it as a charger. 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.
