With the development of mobile technology, portable chargers are becoming increasingly relevant. You can use them not only in tandem with smartphones, but also with other devices: music players, camcorders, navigators, and so on. Today we’ll talk about what portable chargers are.
Design Features
The vast majority of them work on the basis of internal rechargeable batteries. If the battery is discharged, it will be logical that the portable charger will not work . Some accessories may be suitable only for a certain brand of smartphones, for example, only for iPhones. But manufacturers are trying to market universal chargers.
Tips 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 selected based not only on their technical characteristics, but also on the indicators of the device for which you choose a battery. Find out how much power your smartphone consumes, and buy a charger that has 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 the smartphone with energy forever.
3) For long trips created solar panels. If the prospect of a campaign with multiple charging of a mobile phone looms ahead, the solar panel is indispensable.
4) Particularly effective solar panels as portable chargers will be on clear, sunny days. These autonomous sources of energy supply will become a practical analogue of other batteries, because without the participation of a person they can charge connected devices.
5) Some electronic devices do not allow them to be used during the charging process. Do not forget about it. If the power supply 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, one should not forget to fully charge a mobile phone before a long trip. The power supply may not finish to the end, and the gadget will remain without charge at the most inopportune moment.
7) The portable charger for the iPhone 5 is designed in a special way, and we highly recommend not purchasing other types of external power sources so as not to damage the battery of the mobile device.
The criteria to pay attention to. Sources
Portable chargers are equipped with internal batteries. Otherwise, they are called power supplies. To be able to charge the smartphone, you need to keep the power supply itself in working condition. What recharging methods do manufacturers of the bulk of external sources of battery life offer?
1) Computer (using the USB port).
2) Alternating current.
3) The solar panel of the attached or built-in type.
4) Replaceable AA battery.
output power
This parameter is often called the most important characteristic. In the worst case, a portable phone charger should have not just comparable, but equal rated power. However, it is better if it is larger than 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 inputs may vary. In cheap models - only one. In medium - two at once. This is the best option.
Battery capacity
The larger it is, the more charging cycles can be carried out. Usually this characteristic is measured in the dimension “milliamps per hour” and carries the designation “mAh”. Calculating how many times an external power source can charge your smartphone (knowing the battery capacity of these two devices) is not difficult.
