Best Wireless Power banks for iPhones and Android Phones
Wireless power banks are a relatively recent category of portable chargers. Wireless power banks can charge your phone continuously without using a cable by simply placing your phone (or smartwatch) on top of the power bank. This is very handy while working or during travel. You can also use wireless power banks like normal power banks and charge phones normally using cable to get 40-50% more battery back-up.
All wireless power banks can also function as wired power banks. In wired mode, the charging speed will be almost twice the speed compared to wireless mode.
Wireless charging is about 25-30% less efficient than wired charging. To get maximum possible backup from your power bank, it is better to charge in wired mode. A 10,000 mAh wireless power bank will fully charge an iPhone 12 Pro about 1.5 times in wireless mode but charge it two times in wired mode.
