In today’s fast-paced world, staying connected is essential. Whether you’re traveling, commuting, or working remotely, a dead battery is the last thing you need. That’s where power banks come in. But with so many options available, how do you choose the right one?
This guide will walk you through everything you need to know about power banks, from key features to consider to selecting the best one for your needs.
What is a Power Bank?

A power bank is a portable battery that stores energy and allows you to charge your devices on the go. Whether you’re using a smartphone, tablet, laptop, or other USB-powered device, a power bank ensures you stay powered up when an outlet isn’t available.
Key Features to Consider When Choosing a Power Bank
1. Capacity (mAh Rating)
Power bank capacity is measured in milliampere-hours (mAh). The higher the mAh, the more power it can store.
- 5,000mAh – 10,000mAh: Great for smartphones; provides 1-2 full charges.
- 10,000mAh – 20,000mAh: Ideal for tablets and multiple smartphone charges.
- 20,000mAh+: Designed for laptops, gaming devices, and long trips.
If you need to charge a laptop, look for a power bank with at least 20,000mAh and USB-C PD (Power Delivery) support.
2. Output Power & Charging Speed
Not all power banks charge at the same speed. Look for these features:
- USB-C PD (Power Delivery): Supports fast charging for compatible devices, including MacBooks and other laptops.
- Quick Charge (QC) Technology: Provides faster charging for smartphones.
- Multiple Output Ports: Allows you to charge more than one device simultaneously.
3. Portability & Size
Larger capacity power banks tend to be bulkier. If you need something for everyday use, a 10,000mAh – 20,000mAh model is best. However, for laptop charging or extended trips, a higher-capacity power bank is worth carrying.
4. Battery Type
Most power banks use either Lithium-Ion (Li-Ion) or Lithium-Polymer (Li-Poly) batteries. Li-Poly batteries are lighter and more durable, making them a great choice for frequent travellers.
5. Additional Features
Some power banks come with extra functionality, such as:
- Magnetic Wireless Charging
- Built-in LED Flashlights
- Solar Charging for Outdoor Use
