The video explores the longevity and lifecycle of the Anker 737 power bank, or PowerCore 24K. Despite concerns about its lifespan being limited to 300 charging cycles, the presenter argues that this is a conservative estimate and notes that industry standards for lithium-ion cells generally range from 300 to 500 cycles. They highlight that the high power delivery can induce more heat and stress, potentially reducing the cycle life. The presenter offers personal usage data, showing extensive use over several months without significant degradation, suggesting that the device could last around three years. Further, the video clarifies that battery cycles are defined as full discharges, with partial discharges counting as fractions, thus potentially extending the power bank's effective lifespan beyond 300 cycles.

In this part of the video, the presenter discusses the longevity of the Anker 737 power bank, also known as the PowerCore 24K. They begin by addressing rumors about the device being limited to 300 charging cycles. Contrary to this, the presenter suggests that while 300 cycles might be on the lower end of the industry standard for lithium-ion cells (typically ranging from 300 to 500 cycles), it is still a significant amount. They note that the power bank’s high power delivery capabilities can generate more heat and stress the cells, potentially reducing its cycle life. The presenter shares their personal experience, indicating they have used the power bank extensively since August 2022, reaching 36 cycles by December 2022. They calculate that, based on current usage patterns, the power bank could last around three years even under worst-case scenarios.

In this part of the video, the speaker discusses the longevity and lifecycle of power bank batteries. They suggest that batteries might last up to 500 cycles, equivalent to about five years, before their state of health declines to around 80%. Although manufacturers like Anker recommend not using power banks beyond their 300-cycle lifespan due to potential issues like battery swelling or overheating, the speaker believes this is conservative advice. They emphasize that a cycle is defined as a full discharge of the entire battery capacity, clarifying that partial discharges only count as fractions of a cycle. Overall, the speaker provides insights into battery cycles and the realistic lifespan of power banks.
