How to choose the best portable battery charger for smartphone

Load capacity

The millimeter-hour (mAh) battery specification indicates the maximum amount of power your loads can receive. In this way, the higher these values, the greater the capacity of their loads. So the first thing to keep in mind before buying a portable battery is to see if the total values ??of your charge exceed the capacity indicated on the phone’s battery.

Battery power

It is important to choose a portable battery that has a power output power, indicated by the values ??specified in Watts (W), equal to or greater than the charging power of your smartphone.

If the electric current coming out of the portable battery is less than that needed to charge the gadget, the device will not charge. However, the higher the value of this current, the faster the battery can be recharged.

The service life

Remembering the power loss of the external battery when transferring your mAh amounts to smartphones, it is important that your users also evaluate their charge cycle. Also known as a useful life, this cycle can be calculated by comparing the mAh values ??of your portable battery capacity with the mAh indication on the device’s battery specifications.

Tips to increase the battery life of your Android

Recapping the measures to be taken or avoided to optimize the duration of your battery:

  • Charge your battery for shorter periods and more times;
  • Charge it in a cool place; never use your cell phone while charging;
  • Do not leave the smartphone on the bed;
  • Do not leave the battery exhausted and do not store it uncharged;
  • Disconnect charger when charging is complete;
  • Do not attempt to re-connect the phone if it is turned off due to the low battery.
  • Store your battery properly if it is out of use.

Lastly, remember that after 2 or 3 years, maybe before, the battery should be changed so that the usage time can be again satisfactory.
