Adaptors Or Adapters

Power adapter manufacturers: what is the difference between built-in power supply and external power supply?

Built-in power supply and non-built-in power supply chargers are differentiated according to whether there is a built-in voltage reduction and stabilization module. The working voltage of the charger is commonly 11~18V, and there are some 24V, but only for some ultra-high-power models. Our home electricity is 220V, so we need a set of voltage reduction equipment, that is, power adapter, to supply power to the charger.

The vast majority of chargers do not have a built-in power supply. The reasons are generally as follows: first of all, because most of the professional chargers are very powerful, and most of the high-power power supply will be more bulky, not suitable for built-in chargers. Therefore, the general built-in power charger, the power is generally not too large, less than 100W charging power. Like me it commonly used laptop he is not built-in power supply.

Built-in power charger in the charger built-in power adapter, we do not need to purchase additional power can be used. General power is not too large, but there are some power is relatively large built-in power charger generally support external power supply, that is, both can use the built-in power supply, you can also use an external power supply!

The disadvantage is that you need an additional power adapter to use it, which is sometimes not very convenient. Advantages of the built-in power charger: a lot easier for ordinary people to use, at any time to connect 220V can be used, do not need to connect an additional power adapter. In addition to these, power adapter manufacturers also recommend learning more about some other power knowledge, so that usually in the use of power adapters will not be wrong to confuse.
