1c, 2c. The power bank does not require too much current to operate, so just use lithium batteries with a discharge rate of 1c or 2c. Mobile power bank, also known as mobile power bank, mobile power. A portable charger that integrates power and charging functions, it can charge mobile phones and other digital devices anytime, anywhere or provide standby power.
This is possible in theory, but this should not be the case in reality, because the more lithium batteries installed, the more risk and accidents are likely to occur, and the number of printed circuits is limited. .
Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable.
Lithium metal batteries, the fifth generation of rechargeable batteries, were born in 1996. Their safety, specific capacity, self-discharge rate and performance-price ratio are superior to lithium-ion batteries.
