When choosing a laptop charger, there are several options available for you to choose from. Below are some general rules to ensure you choose a laptop charger that meets your needs and will provide great service over the years.
Classic chargers can handle batteries. Original equipment usually works with NiCad cells, but not backward. Most battery chargers work on AA or AAA batteries. Some electronic products require highly customized chargers, which are often provided by the manufacturer.

The average charger can consist of four or more 6 batteries. Ideally, you should have at least one additional pair of batteries easily accessible at all times. So make sure the charger can take the load.
Typical battery chargers are powered by alternating currents. Smaller devices plug directly into the socket and are therefore ideal for on the go.
Since these chargers are deliberate with the passenger in mind, they often run at 100 and 220 volts without the need for an adapter. Cheaper laptop chargers require an external brick converter that supplies power to the charger via a power cable.
These types of chargers are very affordable but too much of a hassle and most can handle 220 volts if no adapter is added.
One of the features worth paying the extra cash for is charger management. Expensive laptop chargers have smart computer chips that turn off the charger when the battery is fully charged.
