How to buy a laptop adapter?

Chargers often burn out with use, usually caused by the rapid aging of parts due to too much current load.Eahunt charger manufacturers have found through research that the ones that have this problem are usually not the original chargers, but the ones that users buy from roadside stalls. Compared to the original, most of them do not have the following circuit protection.

1, over-current protection

When the charger is connected to the current is too large, or a short circuit occurs, generating a great current, if there is a current protection device, the value of the current does not necessarily exceed the value of the overcurrent protection, if it exceeds, this device will automatically cut off the power supply.

2, over-voltage protection:

Access to the voltage is too high, the circuit of the loop is likely to be damaged, such as optocoupler damage or TL431 voltage divider network is affected, over-voltage protection device will automatically cut off the power supply to stop working.

3, over-temperature protection

Charger in the 220V AC into DC, part of the power will be consumed, especially now popular PD fast charging, using high power and low-current way, such charging will produce a great deal of heat, the heat is not emitted, and accumulated to a certain amount of equipment, the internal components will be destroyed, the use of over-temperature protection settings, that is, in the internal installation of a temperature sensor, when the temperature reaches a certain value, it will automatically cut off the power supply and stop working. When the temperature reaches a certain value, it will automatically cut off the current and stop working.

Eahunt is a source charger manufacturers, mainly produces a variety of market 5 ~ 180W specifications of conventional chargers, products with over-current, over-voltage and other 8 circuit protection, charging performance is superior, safe to use. Wholesale from manufacturers with more favorable price.
