So, just like regular power banks for smartphone-dependent teenagers, laptop battery chargers have fast become an integral part of any professional’s setup, specifically those who work remotely or enjoy working at a cafe. The good news is that many laptops today are designed with USB-C charging available. And, it’s not like you can just find an outlet anywhere – even big-name coffee shops like Starbucks are making outlets inaccessible to patrons.
While the battery lives of many of the best laptops are now longer than ever, longevity still depends on how demanding the tasks they’re handling are.
