Question: What is lithium polymer power bank?

Answer: Power banks either use Lithium-ion or Lithium-polymer cells to charge any device. Lithium-ion cells are a type of rechargeable battery which is made of lithium-ions whereas lithium-polymer cells are packed in a soft pouch which makes them more lightweight than the Lithium-ion cells.

Question: Which type of battery is best for power bank?

Answer: Lithium-Ion and Lithium-Polymer batteries are the most common rechargeable cell types found in Power Banks. Lithium-Ion cells are generally cheaper and limited in mAh capacity, while Lithium-Polymer cells can be larger and don't suffer from a memory effect over time.
