In today’s fast-paced world, staying connected is essential, and a dead smartphone battery can be a major inconvenience.

Key Factors to Consider When Choosing a Power Bank
Before diving into the best options, it’s important to understand the key features that make a power bank effective:
1. Capacity (mAh)
- Measured in milliampere-hours (mAh), capacity determines how many times a power bank can charge your device.

Note: A higher capacity means a larger and heavier power bank.
2. Output Ports & Charging Speed

- Wattage (W): Higher wattage = faster charging.
- 18W-30W: Good for smartphones.
- 60W+: Can charge laptops and tablets.
- Multiple Ports: Allows charging multiple devices simultaneously.
3. Portability & Design

- Additional Features: LED indicators, wireless charging, foldable plugs.
4. Safety Features
