At present, the feature that most of the smartphones lack is battery durability for which they can be even called as power hungry. In the case you want to make it through a long commute or a cross-country flight without needing to search for an electric socket to plug in the charger to your mobile phone, you need to purchase a portable battery charger.
So usually when you need to charge your smartphone you have to plug the USB charging cable into the wall-wart transformer. Now, that’s not always convenient or practical in the situation like traveling or you’re away from home.
This is where an external battery charger is really beneficial. They are available a wide range of variety from various colors, size, etc. Instead of plugging your charging cable into the wall, you instead plug the charging cable into the battery pack and fill up the device’s batteries that way.
The device batteries and the external battery packs capacities both are rated in mAh (milliampere hours). Therefore, this should be your principle in determining how much you need to invest in your pack.
Also, besides calculating the battery capacity you need, there’s also the matter of charging amperage. The bigger and more power-hungry your device, the more important having the proper amperage on the USB charging ports is.
You may follow below-mentioned points to buy the ideal portable charging device for your smartphone:
- Decide your total mAh needs and multiply that value by the percentage you want to extend your battery life.
