What are the types of lithium battery cells used in the charger?

With the popularity of large-screen smart phones, battery technology bottlenecks, fewer and fewer mobile phones with standby time of more than one day. This has led to the creation of a new category of products -- portable power supplies, or power bank.

With the advancement of technology, the 5000 MAH charging treasure is still the starting number. 8000, 10000, 15,000 or even 20,000 MAH of mobile power is everywhere. The current charging treasure market is very chaotic, from a few Yuan to several hundred Yuan, all kinds of brands have shook their eyes (a top e-commerce company in China has hundreds of brands on the category of charging treasure). But there are still many doorways in the charging treasure. For example, its appearance, round, flat, long, square, sheet-like and even plush toys! There is also the difference between its standards, such as the airport to talk about the time, not what we commonly call the milliamp. More and more functions, such as storage, wireless routing, card reader functions and so on.

The most important thing in discharge efficiency is the battery. What is it about?

Today's charging treasure batteries are generally divided into 18650 batteries and polymer lithium-ion batteries.

Their appearance is also well distinguished.

Cylindrical, relatively heavy charging treasures are generally 18650 batteries.

The size and appearance of the polymer lithium ion battery can be customized. For example, some very light, strange, patchy power supplies.
