While not strictly necessary, it’s highly recommended to fully charge a new power bank before using it for the first time. This helps the battery’s chemistry to properly activate and calibrate, and ensures you get the most out of the power bank from the start.

Here’s why and how:

Why fully charge a new power bank?
Proper battery calibration:
When a new battery is first used, the electronics need to learn how to measure the full and empty states of the battery. A full charge helps calibrate the battery management system, ensuring accurate readings and display of the remaining power.

First impressions:

A fully charged power bank provides a good first-use experience, ensuring you can use it effectively from the start.
Avoiding unexpected draining:
Power banks often arrive with a partial charge to preserve battery health during shipping and storage. While you can use them initially with this partial charge, fully charging beforehand prevents the power bank from draining while you’re trying to use it for the first time.

How to charge a new power bank:

1. Connect to a power source:
Use the included USB cable or a suitable charger to connect the power bank to a wall outlet.
2. Wait for a full charge:
Allow the power bank to charge fully, as indicated by the charging indicator light or LED display.
3. Follow manufacturer instructions:
Always refer to the power bank’s manual for specific charging instructions and recommended charging time.
In summary: While you can use a new power bank immediately with a partial charge, fully charging it before the first use is recommended to ensure proper battery calibration, a positive user experience, and optimal performance.
