iPads require a significant amount of power to charge, so fully charging your iPad can take a few hours using this method. Avoid using your iPad while it’s charging to increase charging speed.
It’s best to charge devices while your car is running to avoid draining your car battery.
External battery packs have different power ratings, and the charging time for devices varies accordingly. Use only Apple certified accessories for your iPad to avoid any electrical damage. Keep your iPad turned off while it’s plugged in so it charges faster. [3] X Expert Source Gonzalo MartinezComputer & Phone Repair Specialist Expert Interview. 4 May 2021.
