Comparison of the Action 2 vs the Brave 4 Pro

Why size and weight matter: Weight is important for action cameras because we often mount them on helmets, or hold them at the end of a selfie stick while moving. Therefore a heavier camera can be dvifficult to use or uncomfortable. Weight is even more crucial for certain sports like road cycling or running.

Battery life

The Brave 4 Pro offers a much larger battery capacity. The Brave 4 Pro has a removable battery whereas the Action 2's battery is not removable

Why battery life matters: Nothing worse than running out of battery just before capturing the best footage of the day! A long battery life is reassuring and convenient when shooting footage outdoors where options to charge are limited. Even the use of a power bank can be tedious or simply impossible like when filming watersports. Having removeable batteries allows battery swapping on the go which further extends your runtime.

Storage

Only the Action 2 features built-in storage. Both the Action 2 and the Brave 4 Pro support SD cards.

Why storage matters: High quality footage can quickly take up lots of space and insufficient storage can soon be frustrating. Having a large amount of storage and the possiblity to extend it or swap SD cards while on a outing will ensure you will always be able to capture the footage you want. However, smaller, wearable action cameras often rely on built-in storage because of their small size.
