What the Numbers Mean
mAh vs Real Output
As discussed in our buying guide, rated capacity doesn’t equal usable capacity:
- 10000mAh rated → 6200-7000mAh actual
- 20000mAh rated → 12000-14000mAh actual
- 24000mAh rated → 15000-16000mAh actual
Higher-quality power banks have better efficiency ratings (65-70% vs 60-65% for budget).
Wattage Requirements
- Smartphones: 18-30W for fast charging
- Tablets: 30-45W
- Laptops: 45-100W
More wattage doesn’t always mean faster phone charging—phones limit their intake regardless of available power.
