Why Does 20,000mAh Feel Like Less?
- Rated Capacity: 20,000mAh
- Note that power banks typically deliver only 60% to 70% of their rated capacity to other devices. This is due to energy loss from circuit heat and voltage conversion, resulting in an actual capacity of around 12,000mAh to 14,000mAh.
Calculating Actual Charges:
- The formula to estimate the number of charges per device is:
(PowerBank Rated Capacity × 0.6) ÷ Device Battery Capacity ≈ Number of Charges
Example:
- For an iPhone 14 (battery capacity 3279mAh):
(20,000mAh × 0.6) ÷ 3279mAh ≈ 3.6 full charges.
Recharging Time
- Full recharge time varies depending on the wall charger used:
- Using an 18W fast charger: approximately 6 hours.
- With a 5V/2A charger: about 10 hours.
- Or a 5V/1A charger: approximately 20 hours.

- With our 20,000mAh 22.5W power bank, you can expect:
- 2.8 full charges for an iPhone 14 Pro Max (1.4 for iPad Pro).
