What to consider before buying a Power Bank?

To start with, one should always consider their phone size and its battery life. Smartphones with bigger screens tend to have bigger batteries and therefore need a higher capacity power bank. In case your smartphone constantly dies halfway through the day, then you would need something portable to carry around every day.

The following pointers cover many important things to consider for opting a power bank.

  • Usage Frequency: The more it is, the more you would have to carry around. Hence, choose the one which is less bulky with a decent Battery Power like Xiaomi Mi 10,400mAh.
  • Number of Devices: If you carry multiple phones that needs to be charged often, then it’s better to go for something with at least 2 USB Ports with a minimum capacity 20,000mAh.
  • Portability: If you’re always on-the-go and need something light and small for your handbag. Choose the portable chargers that has a capacity of around 5000mAh. They usually take longer to charge and you would have to re-charge them more frequently.
  • Bulkiness: Although it might not sound that important, but it could be a deal breaker for many. Essentially, weight of the power bank is dependent on a number of factors like its internal components, battery capacity and built materials.
