Nowadays it is impossible to conceive a life without smartphones and mobile devices that constantly help us make payments, find streets, restaurants and any other type of information, also representing a good percentage of our daily entertainment.
Of course, these activities involve a considerable consumption of the device battery, greatly reducing the canonical 24 hours of use of a smartphone.
External batteries, or power banks, are useful devices especially for those who spend most of the day away from home since they allow access to a variable energy supply based on its nominal capacity, available for any USB device.

Buying Guide – How To Choose the Best Power Bank?
Capacity and Speed
Modern smartphones are getting thinner and if, on the one hand, the design benefits, on the other hand, the battery size is getting smaller and smaller.
At the same time, functions and energy consumption increase and the problem of autonomy often insufficient for the needs of users, especially of those who use it intensively, is not solved.
External batteries represent an effective response, provided that certain factors are taken into account, such as, for example, the capacity expressed in m ah.
If you have a latest-generation smartphone such as an i phone 6, you could choose a very capable power bank with 20,000 m ah that allows you to recharge it even seven times before having to be charged in turn. In this way you can stay calm for days even away from power sources, knowing that you can count on a reliable battery at any time.
Also take into account the charging times of these accessories which are sometimes incredibly long, perhaps too much for your needs.
It is not only important to be able to charge your device several times, but also to do it as quickly as possible. In this case, we must consider the output current from the ports which are expressed in amperes.
Technology
we talked about ports, in the plural, not surprisingly because external batteries with two USB ports and not only one are widespread on the market, ensuring an important advantage and, that is, that of being able to recharge two devices at the same time, ideal if you often go out with more than one smartphone.
Power banks are often technologically very advanced accumulators and the best brand models are those that automatically recognize the optimal energy needed by the two devices connected simultaneously, releasing the adequate one for each.
The advantage is faster and safer charging, both for the devices and for the battery itself.
Without this function, by connecting two smartphones with different powers, the charging times would be longer because the energy would be distributed equally on both ports.
In short, the models equipped with the most modern technology allow a better and safer refill because they adapt better than others to any brand and model that will be refilled with maximum efficiency and speed.
Design and Dimensions
Of the other components that could influence your choice are, of course, the price but also the design and size. The design has its importance from two points of view: firstly, for an aesthetic fact; many companies make particularly attractive models with different colors to improve their appeal.
Secondly, because it is important to have a handy external battery in your hands that does not scratch at the first impact, with a coating that does not leave unsightly fingerprints.
As for the size, the batteries are not the same because they can all go into the glove compartment of the car or bag, but if you want maximum practicality you may prefer those with such a compact design that you can also put them in your pocket.
How to Use an External Battery
Internal Battery Wear
if you consider that these devices lose speed and efficiency over time, it becomes almost impossible to rely on a single recharge to face the day.
Fortunately, there are supports available on the market that can extend the use of your smartphone when no power outlet is available for quick recharging on the fly: these are external batteries.
Compactness and Capacity
they are more or less compact products, depending on the capacity, to be connected via USB cable to your favorite device, thus enjoying an additional battery.
If the first external batteries did not exceed 2,000 m ah, today it is possible to find very large ones, up to 10,000 m ah, which guarantees various recharges, preventing panic situations when the internal battery of the device reaches 1%.
Compatible Devices
before making the purchase you must consider compatible devices. Always look in the product data sheet for the name of your smartphone or tablet to be 100% sure to buy an external battery that is right for you, avoiding wasting money unnecessarily.
The models differ not only in capacity, size, and external appearance but also for the connections that can be USB, mini USB, micro USB up to the most modern USB type-c and the lightning system used by apple.
Recharge One or More Smartphones
Ask Yourself This Question: How Many Devices Do I Always Carry with Me?
Some external batteries are equipped with more than one USB slot, just to meet the needs of those who, for work or for other types of needs, need different smartphones, tablets or even digital cameras.
The ability to connect them all simultaneously to the same external battery is certainly a convenience to consider.
Use
The operation is extremely simple. First of all, make sure to charge the external battery to the maximum. Then leave it overnight connected to your pc or charger if supplied with the product.
To check the battery charge status, there is usually bright le ds. When they are all completely on, you can disconnect it and, without forgetting the connection cables, take it with you. To use it with devices, all you have to do is connect it to them with the appropriate cable.
Never forget to check the status of the external battery before leaving the house, otherwise, you may find yourself with all the devices discharged and without the possibility of recharging them.
