Why You Do Not Get Full 10000 mah from a power bank of 10000mah
You don’t get the full 10,000mAh from a 10,000mAh power bank due to several key factors:
1. Voltage Conversion Loss
- Power banks store energy at 3.7V (lithium-ion battery voltage).
- When charging devices, they convert it to 5V, 9V, or 12V (USB output voltage).
- This conversion causes energy loss (typically 20-30% loss).
2. Power Bank Efficiency
- Most power banks have an efficiency rate of 70-85% due to internal circuit losses.
- If efficiency is 75%, a 10,000mAh power bank provides around 7,500mAh before conversion losses.
3. Higher Voltage Means Lower mAh
Since energy is stored in watt-hours (Wh), not just mAh:
- 10,000mAh × 3.7V = 37Wh (total stored energy)
- When outputting at 5V:
- 37Wh ÷ 5V = 7,400mAh (before efficiency loss)
- When outputting at 9V or 12V:
- Usable capacity drops further because voltage is higher.
4. Heat & Internal Circuit Losses
- Some power is lost as heat during fast charging.
- Voltage regulators, safety chips, and battery management systems consume power too.
5. Fast Charging Consumes More Power
- Higher voltage (9V, 12V) = Faster charging = More energy loss
- Using 5V 3A mode gives better efficiency than 9V/12V fast charging.
Real Usable Capacity Example
For a 10,000mAh power bank:
- At 5V output (75% efficiency): ~5,000-6,000mAh usable
- At 9V output: ~2,800-3,500mAh
- At 12V output: ~2,100-3,000mAh
