Of all the product categories in electronics, a great variety of battery packs, battery chargers, rechargeable battery chargers, USB charging hub, car adapters, USB power banks and car cigarette lighters are gradually sold at surprising speed.
For high capacity power banks, you would take it for granted that the higher the capacity, the better the power bank is. Generally huge battery capacity will absolutely improve the charging speed. However, there are more things we need to take into account when we evaluate how useful a power bank is.
The Power Conversion Rate
A powerful power bank, for example, with a battery capacity of 10000mAh built in, is basically required to have at the very least a 80% power conversion rate which will need to need of fast charging. And a higher rate, with a higher percentage of power conversion, will have better charging efficiency.
The Charge Cycle
For so many 10000mAh power banks, they are made up with most up-to-date powerful Li-Polymer battery cells that will usually ensure standard at least 500 charge cycles.
Your Phone Battery's Health Condition
Even though you have an excellent power bank, you should keep your phone battery health. Otherwise, no matter how impressively the power bank works, how quickly it's able to charge, your phone battery will lose charge so quickly. Your phone will feel drained of power pretty quickly after a solid charge. Good health condition of your phone battery will help your phone discharge and charge normally.
