What is mAh? — Power Bank & Battery Capacity Explained
mAh stands for milliampere-hours. It's the unit used to measure battery capacity — for both power banks and phone batteries. Understanding mAh helps you choose the right power bank for your needs in Pakistan.
What Does mAh Mean?
mAh measures how much electrical charge a battery can store. Think of it like a water tank — the higher the mAh, the bigger the tank, and the more charge it can hold. A 10,000mAh power bank holds twice as much charge as a 5,000mAh power bank.
Phone Battery Capacities in Pakistan
| Phone | Battery Capacity |
|---|---|
| iPhone 17 Pro Max | ~4,685mAh |
| iPhone 15 Pro Max | 4,422mAh |
| Samsung Galaxy S24 Ultra | 5,000mAh |
| Samsung Galaxy A54 | 5,000mAh |
| Xiaomi Redmi Note 13 | 5,000mAh |
How Many Charges from a Power Bank?
To calculate how many times a power bank can charge your phone, divide the power bank capacity by your phone's battery capacity — then multiply by 0.85 (to account for conversion efficiency losses).
Example: 10,000mAh power bank ÷ 4,422mAh (iPhone 15 Pro Max) × 0.85 = ~1.9 charges
| Power Bank | iPhone 15 Pro Max Charges | Galaxy S24 Ultra Charges |
|---|---|---|
| 5,000mAh | ~0.9x | ~0.85x |
| 10,000mAh | ~1.9x | ~1.7x |
| 20,000mAh | ~3.8x | ~3.4x |
Why Actual Charges Are Less Than Theoretical
Power banks lose approximately 15–20% of their stored energy during the conversion process (from the power bank's battery to your phone's battery). This is normal and happens with all power banks. Higher-quality power banks (like Orashare and Anker) have better conversion efficiency — typically 85–90%.

Frequently Asked Questions
Is 10000mAh enough for a full day in Pakistan?
Yes — a 10,000mAh power bank provides approximately 1.9 full iPhone charges or 1.7 Samsung Galaxy S24 charges, which is more than enough for a full day of use.
Why does my 10000mAh power bank only charge my phone once?
If your power bank only charges your phone once, it may be a counterfeit with a much lower actual capacity than claimed. Original 10,000mAh power banks from Orashare and Anker charge most phones approximately 1.7–2 times.
