Why do we have to choose the right adapter?

It is a power supply conversion device for small portable electronic devices and electronic devices. It generally consists of housings, transformers, inductors, capacitors, control ICs, printed circuit boards and other components. Its working principle is to convert the AC input into the DC output.

How does the adapter work?

The working principle of the adapter is converted from AC input to DC output; Depending on the connection method, it can be divided into wall type and desktop type. Widely used in security cameras, set-top boxes, routers, light bars, massagers and other equipment.

Usage: Generally, the role of power supply is a transformer and rectifier. Household AC current is 220 V, and our computer grounding is 12 V DC. Therefore, it is safe that the power supply is a transformer with rectifier. adapters are transformers.

How to select the adapter?

Before selecting a power supply, first determine three adjustment conditions.

First, the interface of the adapter fits to the device

Second, the input voltage must be equal to the rated input voltage of the load (mobile device) or within the voltage range the load (mobile device) can withstand, otherwise the load (mobile device) can be burned

Third, the output current of the power supply should be equal to or greater than the current of the load (mobile device) to provide sufficient power.

Why do we have to choose the right adapter?

Selection of a power supply with suitable specifications and equipment

The right power supply for your devices is one with suitable electrical ratings. Input voltage and current of the device must match the output voltage and current of the adapter. Check the product label or user manual of the device to see the voltage and current values. Buyers learning how to choose a power supply should know that most power supplies have an output DC voltage of less than 20 V and an input AC voltage of over 100 V.

Choosing an adapter with a higher or lower rated voltage or current may cause the connected device to malfunction. This can happen if the VDC of the adapter is lower than the input voltage of the device, even if they have the same amperage. Using an adapter with a higher voltage may cause the connected device to detect an overvoltage. A power supply that runs at a higher voltage than required will cause the connected device to become hotter. Operating at higher voltages can also shorten the life of the device and burn its internal circuits.

Using power supplies with different currents can be a problem. When choosing a power supply, avoid choosing a power supply that delivers less power than is required by the device. Even if the adapter and the device have the same rated voltage, the device will try to draw more current than the power supply can handle. This can cause the adapter to overheat. The device may not turn on or may have difficulty staying on. If the current is too low, the electronic device can remain on, but its battery will not charge.
