To extend the battery life of Anker portable chargers, you can take a look at the following tips:

• Use the battery within the optimized operating temperature (0°C - 25°C / 0°C - 77°C)
• Do not use it close to a heat source.
• Do not store the portable charger in a hot or humid environment.
• Do not misuse the battery. Irregular use (including but not limited to overuse, using methods, environmental conditions, etc.) will easily lead to performance degradation of lithium batteries, shorten the run time, affect the lifespan, and may even lead to bulging, smoke, and fire.
• It is recommended to recharge the lithium battery periodically (once every 3 months).
