Charging Speed and Output Options
I checked how quickly the external battery could charge my Lenovo T580. Some batteries support fast charging via USB-C or proprietary connectors, which is a huge convenience. Also, I looked for batteries with multiple output ports so I could charge other devices simultaneously.
