Is 20000mAh power bank enough?

This depends on your actual need. Generally speaking, a 20,000mAh power bank is generally considered sufficient for most people's everyday charging needs. However, if you have power-hungry devices or plan to charge multiple gadgets simultaneously, preparing a higher-capacity power bank like the 24000mAh Anker 737 Power Bank (PowerCore 24K) or wired chargers for Samsung or other phones might be more suitable.

Is a 20000mAh power bank better than 10000mAh?

Whether a 20,000mAh power bank is better than a 10,000mAh one depends on individual needs and preferences. A 20000mAh power bank can store more energy but are also heavier and bulkier than a 10000mAh power bank. So, if you prioritize portability, a 10000mAh power bank is ideal.
