Important Notes
- Due to energy conversion losses and heat dissipation during use, the actual usable capacity is approximately 60–70% of the rated 10000mAh—about 6000–7000mAh in real-world scenarios.
- To estimate how many times you can charge your device, use this formula: (Power bank capacity × 0.65) ÷ Device battery capacity = Estimated number of charges. For example: (10,000mAh × 0.65) ÷ 3279mAh (iPhone 14 battery) ≈ 2 full charges.
- Always recharge the power bank via the USB-C port for optimal speed and safety.
- Package includes: 1× INIU 10000mAh Power Bank, 1× Detachable USB-C Cable, and user manual.
- While pass-through charging is supported, it is not recommended for simultaneous laptop charging under heavy load due to potential performance limitations.
Frequently Asked Questions
Why does my power bank provide fewer charges than expected?
External batteries naturally lose some energy during voltage conversion and circuit resistance. Typically, only 60–70% of the total capacity is available to your devices. A fully charged INIU 10000mAh power bank can safely deliver approximately 6000–7000mAh to connected devices.
How do I calculate the possible number of charges?
Use the industry-standard formula: (Power bank capacity × 0.65) ÷ Device battery capacity ≈ Number of charges.
For example: (10,000mAh × 0.65) ÷ 3279mAh (iPhone 14) ≈ 2.0 charges.
How long does it take to fully recharge the power bank?
Recharge time depends on the wall charger used:
- With a 15W charger: ~3 hours
- With a 20W fast charger: ~2 hours
Note: Always recharge via the USB-C port for best results.
Does it support pass-through charging?
Yes, the power bank supports pass-through charging, allowing you to charge both the power bank and a connected device simultaneously. However, avoid using this feature for high-load tasks like charging a laptop during intensive usage.
Is it allowed on airplanes?
Yes, this 10000mAh power bank complies with TSA regulations for carry-on items (≤100Wh ≈ 27,027mAh). You can bring it on flights without needing special approval.
