The NUISK does not specify its recording durations in different modes, but it is similarly positioned for high-quality footage. The ability to record while charging is a standout feature for the i3, ensuring that users can capture longer events without interruption, which may appeal to those needing extended recording sessions.

Waterproof Capabilities

Both the i3 and NUISK cameras come with waterproof cases, allowing them to be submerged up to 131 feet (40 meters). This feature makes both cameras suitable for underwater activities like snorkeling and surfing. The waterproof capability is critical for users who plan to use these cameras in various adventure settings, such as diving or swimming. However, it's worth noting that the cameras themselves are not waterproof without their cases, a standard feature in action cameras.

Battery Life

Battery life is an important consideration for action cameras, and the i3 shines in this area with its rechargeable 800mAh lithium-ion battery. The i3 can record up to 150 minutes in 1080P mode and significantly less in higher resolutions. The NUISK does not provide specific information on its battery life, leaving potential buyers in the dark about how long they can record before needing to recharge.
