In the vast majority of cases, you can charge a phone during a thunderstorm, and everything will be just fine. That said, any expert in the fields of electricity, telecommunications, and construction is likely to tell you that there is still a chance your phone could be damaged. The general recommendation is to unplug.
If your charger gets wet, the first thing you want to do is unplug everything and remove all sources of power. Once there is no power, try to dry the device as best you can. After that, you still need to let it air dry for at least 48 hours before you test the charger to see if it still works.
Wireless phone chargers use magnetic induction to charge your phone. Your wireless phone charger has enough magnetic pull to damage credit cards, security badges, key fobs, gift cards, and hotel room keys. In general, you should always use magnets with caution when working near electronics.
There are two things that have to happen for a laptop charger to work with a phone. First of all, the charger plug must first fit into the phone socket. In addition, the charger and the phone must use the same protocol. This is a fancy way of saying they need to be able to communicate.
Regardless if it’s your phone, tablet, or laptop charger, they all have the same reason for going off and on. Typically, on-again-off-again charging happens because of a poor flow of electricity. But it can also be tied to your power port being dirty, a faulty charger or power source, or maybe it is your battery.
