Product description

Current strength of the charger: 4.74A

The current (ampere, 4.74AA) of a laptop charger determines the maximum current it can provide to the laptop.

This value can be higher than what the laptop actually needs. This won't harm the laptop because the device will only draw as much current as it needs. For example, if a laptop requires a current of 3.5A, and we use a charger with 4.74A, the laptop will still only draw 3.5A. The extra current provided by the charger won't be utilized.

On the other hand, if the charger's current is lower than what the laptop requires, it can cause problems. An undersized charger (for instance, a 3.5A charger for a laptop requiring 4.74A) will not be able to provide the necessary current to the laptop, leading to overheating, underperformance, or even damage to the charger.

In summary, the current of the charger can be higher than the current desired by the laptop without damaging the device, but it can't be lower.

Output voltage: 19V

The output voltage (volt, 19V) of the charger is a key parameter that is necessary for the operation of a given laptop.

This voltage can't be either higher or lower, since the laptop's electrical system expects this value for proper operation. If the voltage is too low, the laptop won't work or won't work properly, as it won't receive the necessary electrical power. If the voltage is too high, it can damage the laptop's internal components, as they are designed up to a specific voltage.

For example, if your laptop requires a voltage of 19V, your charger should also provide a voltage of 19V. Neither more nor less.

That's why it's important to choose the charger according to the specifications provided by the laptop manufacturer, including the correct output voltage. This information is usually found on the label at the bottom of the laptop, in the user manual, or on the manufacturer's website.

Connector size: 5.5mm X 1.7mm

The connector size of 5.5mm x 1.7mm indicates that the external diameter of the given connector is 5.5mm, while its internal diameter is 1.7mm. This is a common size, encountered in a wide variety of electronic devices including laptops, tablets, and other portable devices.

These connectors are most often found in DC power supplies, serving to provide energy to the given device. It's important that the connector size matches that of the device's connector, ensuring the two can fit together and function without interruption.

In some cases, these connectors may have proprietary dimensions, meaning that they require specific or brand-specific cables and adapters. Always check that the connector size matches that of your device before purchasing any new cables or adapters.

Beyond the connector size, it's necessary to take into account the output voltage and current of the power supply to ensure it meets the specifications demanded by the device. If these values do not align, it can result in damage to the device or a decrease in its performance.

Connector size: 5.5mm X 2.5mm

One of the parameters determining the size of a laptop charger connector is the internal and external diameter. If the connector size is 5.5mm x 2.5mm, then the external diameter is 5.5mm and the internal is 2.5mm. This size is a relatively common standard, and is used by several laptop manufacturers, such as Asus, Toshiba, and Lenovo.

It's important to note that the size of the connector is just one of the factors to consider when choosing the right charger. Other important parameters are the charger's output voltage (V) and current (A), but only in the sense that the charger's current delivery capability can be greater than the laptop's current absorption capacity, as the device will only draw as much current (A) as it needs. These values should match those required by the laptop. Most manufacturers indicate this information on the bottom of the laptop, on the manufacturer's sticker, or in the battery area.

If your charger connector size is 5.5mm x 2.5mm, then the new charger should also be this size, and its output voltage and current should also match the specifications of your laptop.

Connector size: 7.4mm X 5.0mm

The laptop charger connector size of 7.4mm x 5.0mm indicates that the outer diameter of the given connector is 7.4mm, while its inner diameter is 5.0mm. This is a relatively larger size connector, which is used in many high-performance laptop models.

The size of the connectors is important as it ensures that the charging cable fits correctly into the laptop's charging port. An incorrect fit can not only impact the charging capability but could also result in damage to the connector and the port.

In addition, a connector of this size is typically found in laptops that require higher power and larger capacity batteries, as these models usually require higher current and voltage from the charger.

Always check the specifications provided by the laptop manufacturer to choose the correct charger and connector. Using the wrong charger can not only impact the performance of your laptop but can also shorten the lifespan of the battery, and in extreme cases, result in damage to the laptop itself.
