Buy laptop chargers
All presented original modules for power supply of portable devices of various manufacturers, are operated from a standard 220 V socket and 50 Hz electric current fluctuations - i.e., suitable for use in offices, our houses and apartments.
Let's analyze their technical characteristics and determine the possibility of replacing one charger (memory) to another.
Parameters of laptop chargers asus, hp, acer, lenovo, ASUS.
Choosing a charging module for a laptop, you need to focus on the following indicators:
- specifications - current or power and output voltage;
- connector (this is a plug that is inserted into the laptop, not into the outlet) - its shape and size.
All characteristics of any power module, as usual, are indicated on the body of its power supply. These are numbers with letters. For example, the HP 18.5 V 3.5 A 65W 7.4*5.0 laptop power Adapter has an output voltage of 18.5 volts, a current of 3.5 amperes and a power of 65 watts. Figures 7.4*5.0 indicate the inner to outer diameter of the connector.
Selection and replacement of the laptop charger
All Lenovo chargers with rectangular connectors have identical output voltage of 20 V, but different power. And thus the power - various the current. If any of them are connected to a laptop, the current consumption of which is higher, the Adapter will "burn".
It turns out that it is possible to replace this Lenovo 65W laptop device with Lenovo 90W, but it is not possible to replace Lenovo 65W with Lenovo 45W. Too it is possible to designate concerning the choice of the block for the ASUS laptop: 90W 5.5*2.5 replace 120W 5.5*2.5, but will not change to Asus 65W 5.5*2.5.
As for the replacement of the charger of one brand on the memory of another brand, then, from the presented lineup completely interchangeable modules Lenovo 19V 3.42 A 65W 5.5*2.5 and Asus 65W 5.5*2.5.
Not fatal (but not desirable), replacement of the charging adpter with one output voltage, the charger with another output voltage. The main thing is that the difference between this indicator was not significant and was +/- 1 - 2 No.
Based on this statement, as well as the above, it is possible to replace the charger HP 65W 7.4*5.0 to Dell 90W 7.4*5.0. Reverse replacement (interchanging), in this case, is excluded not because of the difference in the output voltage, but the difference in the indicators of the power supplied to the consumer by the devices.
If the connector has a different shape than necessary - use an adapter or change the connector to the connector of the required shape.
For example, for a Lenovo laptop to which previously connected already out of service charging with a rectangular connector Lenovo 65W, purchased charging unit Asus 65W 5.5*2.5. with a cylindrical connector and replacing the cylindrical connector Asus rectangular Lenovo.
In the future, when working with a laptop Lenovo, use the device charging Asus 65W 5.5*2.5.
