Sometimes—but only if “bent” means a smooth curve in an otherwise undamaged cable. A sharp kink, split insulation, exposed wire, damaged connector, or bent AC plug is not a DIY repair: unplug it and replace the damaged part. A cable that looks intact but will not charge may need connection or power-source checks instead.
Is a bent charging cable safe to use?
A gentle curve is different from a kink. Apple advises users of its listed Mac cables to “Aim for gentle curves instead of angles in the cable” and warns that repeated bending at the same spot can weaken a cable or make it brittle. That is handling guidance for those cables, not a universal pass-or-fail test for every charger design. Apple’s cable-handling guidance explains how to avoid undue stress.

If the cable has no visible damage, the connectors are secure, and it does not heat up or behave intermittently when moved, a curve alone does not prove that it has failed. Avoid sharp bends and repeated flexing at the same point. If charging cuts in and out when you move a particular section, stop using that cable; the fault may be internal even if the outside looks intact.

Unplug the charger before inspecting it. Check the cable from end to end, including the areas where it meets each connector, and examine the adapter and plug. Take it out of use if you find any of these signs:

Damaged cables or chargers can cause fire, electric shock, injury, or property damage. Apple’s iPhone safety information warns against using damaged charging equipment; Electrical Safety First also advises stopping use when a USB charger shows warning signs (USB charger safety advice).
Can you straighten, tape, or splice a damaged cable?
No. Do not try to straighten a kinked cable, cover damage with tape or glue, apply heat shrink, or splice the conductors. These measures do not establish that the cable is safe, and the cited safety guidance supports discontinuing use of damaged equipment—not DIY cable repair. Unplug it and replace it.

Do not bend an AC plug prong back into shape or attempt to repair a damaged adapter or mains power cord. Apple says to stop using a damaged AC wall adapter or AC power cable (Apple power-adapter and cable guidance). If a broken prong is stuck in an outlet, do not touch it or use that outlet. Switch off the circuit at the breaker only if you can verify that it is de-energized; otherwise, contact a qualified electrician.

- Unplug and reconnect the cable at both ends, making sure each connection is firm.
- Check that the adapter is connected securely to the power source.
- Try a different power source. If available, check with a known-good compatible cable and adapter rather than repeatedly flexing a questionable one.
Apple’s basic charging guidance recommends checking the cable and adapter, confirming the connections, and trying another power source (If your iPhone or iPod touch won’t charge). These checks help when equipment appears undamaged; they do not make damaged equipment safe to use.
