To ensure fast heating and long usage time of Pockety, we use two 18650 batteries in series. If the capacities of individual batteries are inconsistent, during the charging process, the battery with smaller capacity may reach full charge prematurely, while the one with larger capacity remains not fully charged. This can result in the entire battery pack not being fully charged. The industry’s best solution to this is using charging balancing. However, charging balancing also has some drawbacks. Due to the inability to achieve 100% consistency in materials and assembly processes of the two batteries, there may be slight capacity differences between them. These minor differences can only be balanced by weak voltage differences. The smaller the difference, the longer it takes. Sometimes it may take several weeks of continuous charging to eliminate these minor differences. In reality, these tiny differences do not affect the battery output and usage time. Therefore, you may notice that some Pockety devices keep charging continuously. Additionally, because our engineers initially did not realize that this could confuse users, we deeply apologize for this. We will try to avoid this issue in program as much as possible in subsequent batches. Now, as long as you ensure that the battery indicator shows full after unplugging Pockety from the power source, it means it’s fully charged.Depending on your charging adapter, this usually takes between 2.5 to 6 hours.

Furthermore, according to our tests, inferior charging adapters may cause Pockety to consistently not fully charge. Please make sure to use qualified charging adapters
