The charger block (18w) I use for my iPad Air (Gen4) gets very hot when connected. Is this normal?
Is a higher wattage — maybe 30w or 60w — any more efficient? Would they harm the iPad in any way?
What if I use a longer cable — say, 6’ or 10’?
Really confused here…. Thanks.
iPad Air, iPadOS 15
Your iPad Power Adapter may become very warm during charging; this is entirely normal.
You can safely use a higher wattage USB-PD (Power Delivery) Power Adapter if you choose to do so. The iPad will still charge at its maximum supported charge rate (dependent upon model, up to 18-20W) from the connected Power Adapter; drawing less power than the Power Adapter is capable will cause the charger to run much cooler - although overall power “efficiency” may not necessarily improve. Ensure that the Power Adapter supports USB-PD to ensure compatibility; Apple does not support other proprietary charging standards - such as QC (Quick Charge).
Due to greater circuit resistance, longer power cables require thicker-gauge conductors to maintain the same power transfer. Always use good quality cables from well known manufacturers.
