The vast majority of them work on the basis of internal rechargeable batteries. If the battery is dead, then it is logical that the portable charger will not work. Some accessories may only fit certain brands of smartphones, such as iPhones only. But manufacturers are trying to bring universal chargers to the market.

Advice for those who decide to buy an external battery

There are general recommendations that will be of interest to users:

1)Portable chargers should be chosen based not only on their technical characteristics, but also on the performance of the device for which you choose the battery. Find out how much power your smartphone consumes and buy a charger with more power.

2) Do you like to travel? Then you should purchase another power supply. This time for a portable charger. It will not be able to provide a smartphone with energy forever.

3) Solar panels are made for long journeys. If the prospect of a hike with repeated charging of a mobile phone looms ahead, then a solar panel is indispensable.

4) Solar panels are especially effective as portable chargers on clear, sunny days. These autonomous sources of energy supply will become a practical analogue of other batteries, since they will be able to charge connected devices without human intervention.

5) Some electronic devices do not allow you to use them during the charging process. Don't forget about it. If the power bank will be charged from the solar panel, you will also not be able to use it to charge the device.

6) Despite the presence of an external battery, do not forget to fully charge your mobile phone before a long hike. The power supply may not be completed to the end, and the gadget will be left without a charge at the most inopportune moment.

7) The portable charger for iPhone 5 is designed in a special way, and we highly recommend not to purchase other types of external power sources, so as not to damagemobile phone battery.

1) Computer (using USB port).

2) Alternating current.

3) Attachable or embedded type solar panel.

4) Replacement AA battery.

Power output

This parameter is often called the most important characteristic. In the worst case, a portable phone charger should have not just a comparable, but an equal power rating. However, it is better if it is larger than that of the smartphone that is supposed to be charged. Otherwise, the devices will be discharged on the contrary.

Connectors and interfaces

Portable chargers are equipped with outputs of several standards: ordinary, mini and micro. There are models that work with adapters. The number of entries may vary. In cheap models - only one. In the middle - just two. This is the best option.

Battery capacity

The larger it is, the more charging cycles can be carried out. This characteristic is usually measured in the dimension of “milliamp per hour” and isdesignation "mAh". Calculating how many times an external power source can charge your smartphone (knowing the battery capacity of these two devices) is not difficult.
