Criterias of choice
There are a number of technical parameters to consider when purchasing an additional battery. Many laptop computers require 19 volts. Some laptop models require 12 volts. The main characteristics to be guided by when buying: charge current, voltage, capacity, charging method, number of adapters and interface, material, design, additional functionality.
The external battery must have a USB input and amperage equal to and higher than that of the computer. For fast charging, the required amperage is over 2.5 amps. Various USB inputs allow additional charging of cell phones, tablets, smartphones.
When choosing the size of the external battery capacity, you should take into account the capacity of the laptop's internal battery. If the capacity of the internal battery is 5 amperes per hour, it is necessary to select a battery with a capacity of up to 10 amperes per hour. When charging additional devices, the total capacity should be doubled.
To charge from the mains, the kit must include a power connector. Without it, the charging process will be slow. There are corresponding adapters for different laptop models. When buying an external battery, you need to clarify whether the kit includes an adapter for a specific brand of device. Basically, the market offers buyers low-cost battery options with a housing made of plastic. More expensive metal batteries are less common.
Experts advise you to choose a laptop with a good battery when buying. With the addition of a capacious external battery, the device will be provided with power for 2-3 days.
