How to Choose the Best Power Bank
Choosing the right power bank involves understanding your needs and priorities. Here are some factors to consider when selecting a power bank:
Battery Size: Power banks range from giving you a single charge to several charges, and may increase in size and price accordingly. Consider your usage patterns to pick the right capacity.
Portability: While some people want giant power banks for multi-day adventures, others prefer something small they can hold in their pocket for daily charging or emergencies. Assess your lifestyle to choose accordingly.
Design: Some want something stylish and sleek, while others want total geekery and get something that’s more like a charging computer than a simple power bank. Make your choice based on personal preference.
Weight: Big power banks can really pull on your pocket or bag, so choose wisely if you intend to carry it around with you.
Ports: Do you want one or two or more ports? Do you need USB-A or will USB-C be fine? These are points to consider before making a purchase.
