How to choose the best portable charger for your smartphone?

Best portable charger

The battery of the phone, but also that of the tablet, with the increasing use of apps and online services, tends to last less and less. For this reason, the purchase of the best portable charger is essential in order not to run out of battery out of the house. But what characteristics do we need to check before purchasing?

Power banks allow us to recharge our devices without the use of an electrical outlet. They are ideal while we are travelling or during a long day of work or while doing research for our studies. There are countless Best portable chargers, each different in power, shape, weight and size. Some even have cables included and others have multiple ports, for charging multiple devices at the same time. In short, if we do not have great knowledge, it is not easy to choose the best charger. Let’s see how to do it.


The essential aspect is obviously power. Having a Best portable charger that can’t even fully charge our phone might be useless if we have to be away from home for any longer. Likewise if we only need a small hand to make it through to the evening then it might be fine. As always, everything depends on our needs. Which must be evaluated well so as not to spend our money in vain. To understand the power of the charger we have to check its mAh, that is the milliampear hours. The most common sizes range from 2000mAh up to over 30000mAh. Obviously, the greater the power, the greater the cost. The small 2000mAh chargers will guarantee a 50% recharge to a smartphone. Although this factor depends on the total battery capacity of the phone. They are therefore recommended more for small devices such as GoPro, Kindle and Bluetooth headsets. A charger with 10000mAh instead will guarantee your smartphone between 3 and 4 recharges. Always pay attention to compatibility, otherwise the phone battery could be damaged by the use of these devices.

A charger, for tablets or smartphones, must first of all be easily transportable. Having a very powerful but too heavy power bank could be useless. Everything always depends on our needs. If we need a charger for a trip or for an off-site work then it is much better to opt for light solutions that fit inside a pocket and do not weigh in a suitcase.

Power output:

Another aspect to consider is to understand the output power of the charger that will affect the speed with which smartphones will be charged. Furthermore, this aspect is to be considered especially if we usually recharge multiple devices at a time. Otherwise, if the output power is not sufficient, we will not get good results on any of the devices put on charge.


Do we only use the smartphone or do we need a recharge for tablets and accessories too? And why not buy a nice power bank for the whole family or to use on a trip with friends? In this case too, our needs make the difference. Chargers with multiple ports, to charge multiple devices at the same time, require more power and therefore cost more. But they are essential if we want to use them with more people.


A secondary aspect to consider is the presence or absence of cables and connectors. A power bank must always have a cable for connection to the power outlet. Less useful are the USB connection cables with smartphones and tablets. In this case, it would be better to use the official ones of the device.


Speaking in terms of charging the Best portable charger it is important to keep some numbers in mind. The input of a power bank varies from 1Amp up to 2.4Amp. This means that the higher the amps the faster the recharge will be.

Protections and certification:

Then there are a whole series of aspects to prefer on a portable charger. First of all, the efficiency, that is the working temperature of the charger. It is important that it does not overheat causing injury to people or devices. And let’s remember that at extreme temperatures, both hot and cold, it is highly not recommended to use these devices. Finally, we only buy certified devices.
