1. Capacity
   A power bank's capacity is measured in milliampere-hours (mAh). It determines how much charge a power bank can hold and how many times it can charge your device. For example, an iPhone 14 has power capacity of 3,279 mAh, you'll need a power bank with a capacity of at least 3,279 mAh to fully charge your phone once, or about 9 times on EXCELLION™ 30000mAh power banks.

2. Output
   The output of a power bank refers to the amount of power it can deliver to your device at once. The output is measured in milliamperes (mA) or amps (A). Look for a power bank with an output that matches the charging requirements of your device.

3. Number of Ports
   The number of ports determines the number of devices you can charge at once. If you only need to charge one device, a single-port power bank is sufficient. However, if you need to charge multiple devices, consider a multi-port power bank.

4. Size and Weight
   Consider the size and weight of the power bank if you plan on carrying it with you. Choose a compact and lightweight option if you want something that's easy to carry, such as EXCELLION™ 20000mAh power banks.

5. Charging Speed
   The charging speed of a power bank refers to how quickly it can charge your device. Some power banks offer fast charging capabilities, while others take longer. If you need to charge your device quickly, look for a power bank with fast charging capabilities.

6. Price
   The price of a power bank can vary greatly, depending on its capacity, features, and brand. Determine your budget and look for a power bank that offers the features you need at a price you can afford.

7. Brand and Warranty
   Consider the brand and warranty when choosing a power bank. All EXCELLION™ power banks come with 6 months warranty.

Choosing the right power bank can be a challenge, but by considering the factors outlined above, you can find the perfect option for your needs. With the right power bank, you'll never have to worry about your devices running out of power when you're on the go.
