These batteries are connected through PCB (Printed circuit board), through which internal battery operations are controlled.

Power bank provides an external source of power for recharging electronic devices. It stores electrical energy in batteries and supplies whenever required. It is commonly used to recharge electronic devices like smartphones, MP3 players, digital cameras, Laptops, Tablets, etc.

Lithium-ion batteries – These are high energy density batteries i.e. more electric charge can be stored in a given size. Lithium-Ion batteries are cheap, as they are easy to manufacture as compared to Li-polymer batteries. These batteries can lose charging capacity over time. Heavier in weight compared to Li-polymer batteries.

Li-Polymers batteries– These batteries are more flexible to manufacture in different shapes. Lithium-Polymer batteries are costlier then Li-Ion batteries because their manufacturing cost is higher. These batteries can retain better charging capacity over time as compared to Li-ion batteries. These are light in weight. They have lower energy density compared to Li-ion batteries.

How power bank works

power bank buying guide
