What Is a Mobile Power Supply?

Mobile power supply , mobile charger (power bank, bank charger, power bank , urine bag, nurse; English: Power bank ) is a kind of personal electronic products that can be carried by individuals and can mainly store power. For example, portable chargers for wireless phones, laptops, etc. are especially used in situations where there is no external power supply. Its main components include: a battery used for energy storage, a circuit (DC-DC converter) that stabilizes the output voltage, and most mobile power supplies have a charger for charging the built-in battery.

Mobile power supply , mobile charger (power bank, bank charger, power bank , urine bag, nurse; English: Power bank ) is a kind of personal carry-on, it can store power, mainly handheld mobile devices, etc.

1. Power supply efficiency: During voltage conversion and charging of mobile power, electrical energy is lost. The less the loss, the better the performance.

2. safety protection:

3. Overcharge protection: prevent the battery from being overcharged.

4. Over-voltage protection: Prevent the battery charging voltage from being too high.

5. Over-discharge protection: prevent the battery from discharging too much.

6. Overload protection: to prevent continuous discharge under high current conditions at the output.

7. Short-circuit protection: Prevent short-circuit detection at the output and stop power supply.

8. Overheating protection: prevent excessive temperature.

9. Voltage and current stability.

10. The quality of the battery. ^[1-2]
