🤔What are the different types of external batteries?

There are two main types of external batteries. Shell batteries, which are intended for the use of a single device, usually a smartphone. They are positioned on the back of the latter and also acts as its name suggests as a protective shell. Their disadvantage is that they can only be used on a specific device.

And there are the so-called classic external batteries. With one or more USB ports (Type-C, USB-A, micro USB) in rectangular or cylindrical shape with capacities ranging from 2500 up to 50,000 mAh. Manufacturers do not pride themselves on charging speeds and some have even invented specific terms and technologies to boast about the efficiency of their batteries.

Size, weight, but also charging frequency and power delivered by the battery you want to buy are the main elements to take into account before choosing an external battery. So, if you want to use it for occasional use, it is better to turn to models with a lower capacity and therefore logically more compact and easy to transport.

On the contrary, if you are going on a trip and intend to bring your devices with you, a battery with a minimum capacity of 10,000 mAh with several USB ports is recommended. Regarding the size and weight, it all depends on where you are going to use your devices.

If you want a smaller footprint, you should logically turn to the most compact models. Some do not sacrifice their performance, however, and offer several USB ports as well as a decent charging capacity (this is the case of the Anker PowerCore Slim).

💰What budget for an external battery?

Entry-level models start at very affordable prices – between 15 and 30 euros. For batteries offering, for example, a sealing certification or a fast charging system, it is necessary to count between 35 and 70 euros. Other high-end models can reach 150 euros. A small investment which in any case will allow you to never run out of battery wherever you are.
