Using Apple power adapters
Depending on the model number and your region, your Apple product might include some of the following: an AC power adapter, an AC wall adapter (duckhead), a USB AC wall adapter, a USB charging cable, or an AC power cable.
Use these tips to keep your power adapters working properly
- Never charge your device when moisture is present, as this can cause fire, electric shock, injury, or damage to your Apple product or other property.
- Make sure you’ve fully inserted your AC wall adapter (“duckhead”) or power cable into your AC adapter before connecting the AC adapter to a power outlet.
- When you unplug a cable from your product, a power source, or an AC adapter, hold on to the connector at the end of the cable. Pulling on the cable itself can strain the connector joints or cause breakage.
- If your AC adapter has blades or prongs that fold, be sure to fold them down for protection when you store the adapter.
- Keep ports and connectors on your AC wall adapter and AC power cable free from foreign objects and debris.
- Make sure your adapter is used in a well-ventilated area. If used in a poorly ventilated space like near a couch, under a blanket or on thick carpeting, the adapter might turn off to prevent overheating.
Identifying damaged AC power adapters or cables
If your power adapter, AC wall adapter, or AC power cable has been damaged, stop using it. If you’re unsure about whether an accessory is damaged, take it to an Apple Retail Store or Apple Authorized Service Provider for evaluation, or contact Apple Support.
Signs of damage include but aren’t limited to:
- Any breakage or visible wear on a cable’s outer layer
- Bent, missing, loose, or broken AC prongs or blades
- AC blades that won’t lock into place, or that have black marks or other visible damage
- Sparks issuing from somewhere other than the blades of a plug
- Breakage, visible damage, or discoloration of the adapter casing
- Popping sounds from within the AC wall adapter or anywhere on the AC power cable
- AC adapters that don’t power your device
Note: If the blade or prong on a power adapter or prong on an AC power cable is visibly loose, bent, or broken off and stuck inside an electrical outlet, there’s a safety risk. Follow these steps:
- If a blade or prong on an AC wall adapter or AC power cable seems damaged or gets stuck in a wall outlet, don’t repair, touch, or remove it, and don’t touch or use the electrical outlet.
- Remove the risk of electric shock from the affected outlet by turning off all power to that outlet from your circuit breaker or fuse box. If you’re unable to turn off the power to the electrical outlet, or can’t confirm the power has been turned off, contact a qualified electrician.
