An external battery will be useful to recharge the charge level of a mobile phone, tablet or laptop in conditions when it is not possible to use the electric network. In our ranking of the best portable chargers, you will find great power banks for any gadget.
Which portable charger is better to buy
When choosing a portable battery, you should pay attention to a number of important criteria. The main one is the capacity of the device.
The required indicator depends on the number of connected devices, the volume of their drives, the activity of using gadgets.
Portable battery capacity is measured in milliampere-hours. For comfortable use with multiple devices, this value should be twice the average battery capacity of a mobile phone.
In modern smartphones, it can reach 3500 mAh, which means that a power bank is needed with a capacity of at least 7-8 Ah.
The output current affects the charging speed. It is important that this indicator is greater than or equal to the value provided by the manufacturer of the mobile device. Otherwise, replenishment of the battery will be extremely slow.
Not all portable chargers are suitable for laptops. Here you will need an increased indicator of the output voltage of the portable battery – from 16 to 20 V.
The power recharge rate of the power bank itself depends on the input current. The optimal value is 1.5 A. This is enough to increase the energy reserve of a portable battery with a volume of about 9000-1000 mAh to a maximum of 7-8 hours.
Additional important characteristics that affect the choice of model include the presence of connectors of various types and their number.
A large-capacity battery with multiple charging outputs ensures successful replenishment of the battery for two or more devices.
