How well do you know about the adapter?

The adapter is an electronic device for small portable electronic devices and power conversion devices. It consists of housing, transformer, inductor, capacitor, control chip, PCB and so on.

What is the best way to use the adapter?

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.

It may surprise you to know that you can use an adapter with a higher current than your device. This recommendation applies as long as both devices have the same rated voltage. For example, a 10V/8-A adapter can safely power a 10V/5-A device.

What is a power supply?

1.Chargers are used to charge devices such as batteries or ultracapacitors, while adapters are devices designed to provide the device with the required energy.

2.There are no AC-AC chargers, as all batteries and ultracapacitors are charged with DC and not AC, but there are AC-DC and AC-AC adapters on the market, which are used to power DC or ultracapacitors. Power AC devices.

Normally, the rated output voltage of the charger is greater than the voltage required by the device. For example, a 4.2-V battery requires a 5-V charger. On the other hand, adapters require the same output voltage as the device. For example, a 5V DC fan requires a 5V DC adapter.

How do we choose a power supply with suitable specifications and what is the device?

The right power supply for your device 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.
