Flying is one of the most efficient ways to travel around the world. Indeed, they are both fast and safe. However, the journey can be long, depending on the distance to be covered. Several stopovers are also possible in these cases. To entertain themselves during flights, some people use their mobile phones to watch movies or listen to music. However, the batteries of these devices can become flat, especially during long hours of flight, hence the need for an external charger.
Definition and characteristics
An external charger or powerbank is a portable device for charging the batteries of mobile phones, computers and tablets. It acts as a backup battery especially when it is impossible to find a source to charge the phone directly. It comes with a charger and a micro USB cable. It is thanks to this cable that the phone can be charged.
Benefits of use
An external 10,000 mAh charger alone can charge nearly two tablets and four mobile phones. This makes it convenient because it can be used for several days. It is available in a choice of power and colour. However, for an external computer charger, a power of 50,000 mAh is recommended. Therefore, with this battery, you could continue to work wherever you are or in case of a prolonged power failure. The lifetime of an external charger ranges from 300 to 1000 charge cycles.
Where to get it
External chargers are nowadays fashionable and within everyone’s reach. Moreover, the price varies according to the brand and the power of the device. It’s robust and there are even external solar batteries that charge in sunlight (still handy in places without electricity). External batteries are available at electronic and computer retailers where salespeople can advise you on your purchase. They are also available at some supermarkets.
However, an external charger should be chosen according to the characteristics of your mobile phone or tablet to avoid damage to the battery.
