Smartphones have evolved to become the best assistant one can have. They are fast, have hi-resolution screens, support advanced photography features, but what most important, they are specially designed to comply with industry trends that request a sleek and thin body design. Our mobile phones can guide us through places, keep us connected in various ways, allowing us to purchase goods and much more. As they are often made to look as elegant as possible, the amount of battery capacity that can be applied on smartphones is limited, even the best-advanced phones you can buy barely will keep it on throughout the day.
The horrors of facing dead phone scenarios accompany us on a daily basis. It just isn’t possible to always maintain your device fully charged, using the built-in power save mode will lower the screen brightness and all you can do is pray to the smartphone gods to keep it on until you reach the plug socket. The current large-battery-capacity alternative phones are outdated and offer little regarding security and feature supports. A smarter choice is the investment on a portable battery charger (power banks).
Powerbanks come in different varieties, designs, and capacities. From the tiny lipstick-sized banks that can flow some juice to your phone, or to any USB-rechargeable device, to the large power banks that can revive your device multiple times. The later one is ideal for trips.
The number of times a power bank can recharge your device depends on the battery capacity of the bank and of your device. The capacity is measured in milliampere-hours (mAh). The iPhone 7 has a battery capacity of 1,960 mAh while the Samsung Galaxy S8 has a whopping battery capacity of 3,000 mAh. Larger devices attend to pack batteries with a larger capacity, but the same can also be said for portable battery chargers. There are large enough power banks that can repeatedly recharge your Galaxy S8 almost ten times without having themselves to be juiced up.
