How to Choose the Right Power Bank
Choosing a power bank isn't just about a big capacity number. Consider your daily usage to make the right choice from the start:
- For basic daily use: If you use your phone normally and need one extra charge, 5,000-10,000mAh is enough
- For heavy use & travel: If you travel or use your phone heavily, choose 20,000mAh — charges your phone 4 full times
- For laptops & multiple devices: You need 25,000mAh+ with PD support at 60W or more
- Fast charging: Make sure it supports USB-C PD (Power Delivery) — charges iPhone from 0 to 50% in 30 minutes
- Number of ports: If you charge more than one device, choose a power bank with 2+ ports

Tips to Extend Your Power Bank's Lifespan
- Don't let it fully drain: Charge it when it reaches 20% — complete drain reduces lifespan
- Avoid heat: Don't leave it in a car under the sun — heat is the battery's worst enemy
- Use original cables: Poor cables slow charging and may cause safety issues
- Charge monthly at minimum: Even if unused, periodic charging maintains battery health
- Buy from trusted sources: Fake power banks are a real danger — buy from authorized dealers only
