Choose 5,000mAh for light emergency charging, 10,000mAh for balanced everyday backup, and 20,000mAh or more for travel, several devices, or supported laptop charging.
Capacity is not the only factor
The printed battery capacity is not identical to the energy delivered to a phone because voltage conversion and normal efficiency losses occur. Compare capacity together with output wattage, size, and weight.
5,000mAh for minimum bulk
This size works well when pocketability matters most. It is suited to top-ups and emergencies rather than repeated full charges during a long trip.
10,000mAh for everyday balance
This is a practical middle ground for commuters, students, and office users. Models differ in wireless charging, built-in cables, displays, and charging speed.
20,000mAh and above
Larger models suit travel and multiple devices. For laptops, verify high-wattage USB-C output. Always check current airline rules before flying.
Buying checklist
- Estimate how many devices need charging
- Compare output wattage
- Consider weight and built-in cables
- Check airline limits before travel
