Power Banks have become the rage and people of all age groups are opting for Power Banks of different shapes and sizes. The varied use of phone and the importance of battery have made Power Banks inevitable.
What is power bank?
Power-Bank is the charging device that comes with an inbuilt battery that can be used to charge other devices. The battery fitted in the Power-Bank is used to store the electrical energy directly from the power source and this stored energy is then transferred to other devices charged with USB cable. These battery banks are very handy and come in portable designs.
Different types of Power-Bank
All Power Banks are meant for charging but the way in which they are charged would decide its type. There are two major types of Power-Banks popularly used worldwide –
Solar Charged Power-Bank – This type of Power Bank is charged by solar power. The photovoltaic panels are provided in this Power Bank to initiate charging whenever the Power Bank is placed under sunlight. The charging in this type of Power Bank is not very fast and hence conventional cable charging is also provided for faster charging.
Universal Power Bank – This is the standard Power-Bank that comes with different battery configurations. It is available in various shapes and sizes. The designs vary from pocket size to normal phone sized Power Banks.
How does Power Bank work?
The Power Bank is charged in the same way as the phone. You can charge it directly from the power source or you can use your laptop to charge this portable battery bank. The time taken for charging would depend on the size of the battery. The number of charges possible with this Power-Bank would also depend on the Power Bank battery and phone battery. For e.g. if the battery capacity of your Power Bank is 2000mAh then it would charge 1500mAh phone once. You can’t expect 100% conversion as some of the power is lost during conversion.
What type of Power Bank one should select?
The selection of the Power-Bank depends on its size, shape, and most importantly battery capacity. The battery capacity of the Power Bank should be more than the phone battery capacity, so that it ensures at least single charge. You can go for bigger battery to get multiple charging but in that case, the size of the Power Bank would increase substantially and the charging time for the Power-Bank would also be very high.
So, opt for the Power-Bank that offers you the complete charging solution along with convenience of carrying it anywhere anytime without increasing the burden on your bag.
