Buy adapters for laptops

If the power supply adapter for your laptop is damaged or lost, the safest way is to buy a new one just like the old one. But you may not be able to find such a thing or the price is too expensive. Could this case buy an equivalent?

Adapter is probably the least noticeable part in a laptop. Therefore, the damage, loss . very often occur for this component. In such cases, most solutions are to buy a new adapter in the same way as your laptop.

Can an equivalent replacement adapter be purchased for a lower price but still have the same quality (or more) of the adapter included with the machine? Some of the following tips can help you accomplish this:

1. Preview the voltage before buying a new adapter: the voltage (in V) and the current consumed (in A) of the laptop's plug are indicated on the stamps below the machine. If it is not possible to find an adapter with 100% correct voltage, the adapter with a voltage of high or lower than 5% may still be an appropriate option. The power supply capacity must be equal to or higher than the maximum current consumption recorded on the machine a little (select the higher current the adapter you buy will run cooler).

2. Types of adapters for laptops are those that operate on the principle of electromagnetic energy conversion with electronic circuits in combination with switching transformers, absolutely do not use adapters of conventional transformers (regulator ). Features that help you distinguish between light-weight switching adapters, small sizes, large currents and large supply voltages. If the specifications are equivalent to switching adapters, the regulator will be three times larger, weigh a lot more, and the input voltage is always fixed at a single level (220V or 110V).

3. The DC (jack) level of the adapter must be of size compatible with the socket of the machine and have polarity along with the polarity of the machine (usually the anode will be inside but there are still some computers used). Use an external positive so pay attention when buying. When the adapter you choose is reverse polarity, you should ask the technician to reverse polarity.
