Under the premise of normal use: If it is a new imported lithium battery core, use it once a day, and use 2-3 years to ensure the capacity is more than 80% of the initial capacity. If it is a normal lithium battery core, then generally speaking, there will be no significant capacity drop for one year. And if it is a second-hand teardown battery, then it is really difficult to say, not only has a short life, but also safety is a big problem.
In other respects, it is related to the good words of the circuit. If you use a booster circuit without protection function, it may be broken several times (overshoot and overdischarge will seriously affect the life of the lithium battery), so I hope to buy a life. Longer mobile power bank, it is recommended to buy quality guaranteed or better reputation. In addition, good usage habits are also a way to extend the life of the mobile power bank.
