iPhone Exposed to high voltage into charging port, HELP

Unfortunately, attempting to charge your phone with a hastily made direct connection to a wall outlet most likely did irreparable damage. Virtually every cellphone requires an adapter for charging. These adapters electronically performs several crucial functions; converts 120v ac to 5vdc and restricts amperage to less then 2 amps. In Europe, wall outlets are 220v ac. Every rechargeable battery operates in dc (direct current) mode. Wall outlets in America supply 120 volts of ac (alternating current) and cannot recharge batteries directly but will destroy them and any circuitry between battery and ac wall power. In your case, the high voltage simply overwhelmed the cellphone electronics and destroyed it with incorrect power. The application of wall power simply overwhelmed the cellphone with high power and burned up any tiny electrical connections instantly, vaporizing them and rendering your phone permanently destroyed.

Never attempt short cuts when recharging phones, tablets, laptops and other portable devices using rechargeable batteries without the correct adapter designed to recharge and power them. If away from outlets for a long time like hiking or camping, portable battery packs are available, holding large amounts of power for recharging phones in areas without power. These portable (and rechargeable) battery packs are configured to supply correct power to most phones, tablets and laptops with the correct connectors, preventing incorrect voltages to portable electronics needing power. Adapters are available everywhere at low cost to make it worth having an extra in case one fails.
