The laptop adapter purchase recommended

1.Selected brand:
Substandard products sold online are cutting corners, normal use should be no problem, once the unexpected will burn your laptop, and to cut dozens of blocks has burned thousands of pieces of notebook more harm than good, (cut corners The common practice of arbitrary standard Liteon laptop adapter, such as the actual 19V3.42A, but marked 19V4.74A, this will lead to charging is very slow, or even damage the laptop battery and laptop also remove some protection, this is even more horrible and unexpected on burned laptop.)

I suggest you ample funds, you can buy a professional brand (ie professional Asus laptop charger brand, rather than what the power to do the kind of only such professional brand-specific products was not on the battery and damage to the laptop, and state-of-the-art protection circuit.) such as N17908 the (Asus’s brand) (though these brands are mainly in Europe and North America sales, rarely found in domestic retail)

2.points clear purpose:
Want household and office with sold to buy a home (AC use), you want to use the car, buy a Laptop Car Charger, you want to use in the aircraft on the basis of the vehicle with a aircraft head on it. Home, car, airplane, wants to take into account, buy a combo or triple. However, if you do not want a computer bag multiple weight, you can put in the house, put a car, put a office, so that you can not bring to bring plug to plug go, more convenient and can give around with .

3.points clear of voltage, current and connector:
Look at the original laptop brand, original Acer charger behind the label, write V, the number of A (generally written in the the OUTPUT behind), the compaq charger connector is probably round or square, or porous do to himself probably several, they are not to buy the wrong, or even been fooled.

For example, you originally attached to the hp laptop charger 18.5V 3.5A that have to buy the output 18.5V As for the current higher than 3.5A can. hp 710412-001 laptop adapter.Merchant Referral 18.5V, you’d better not, Although you can charge the special circumstances of emergency can charge, a long time to be battery and laptop causing damage. That voltage accuracy (can not be the way high or low), the current can be high (but the higher the more expensive).

Purpose:
1.AC (such as home, office with AC called AC)
2.DC (such as the car, on the plane with the DC called DC)
Instance Acharger the of ALS-185A35C (number followed by the letter A is indicated by AC current)
For example Acharger’s of ALS-185D35C (figures behind the letter D is for DC)
(Find Acharger product numbers will be preceded and ALS, ALS is the meaning of the single-band Gateway laptop charger
Singel-output Fujitsu Laptop Adapter combination of the first letter abbreviation)
