USB-C not charging? Try these tricks

Is the USB-C plug bent or blocked?

Cables can’t take infinite abuse, so if your cable has a bent plug or is clogged up with dust or bread crumbs, it can easily halt all charging. Look at the plug as well as the receptacles on your device for foreign debris or damage under a good light and perhaps with a magnifying glass. Yes, a garlic crouton can indeed prevent charging (ask me how I know).

Adventurous souls may want to try a wood or plastic toothpick to pick out large debris. A can of compressed air gently blown into the receptacle may also help dislodge foreign matter. For most people though, a new cable may be the only solution.

Try unplugging the cable and plugging it in again

Yeah, this one is simple and you’ve probably done it already, but sometimes the device and charger can fail to negotiate the correct charging policy so you get bupkis out of it.

This often happens if the plug or the receptacle — the thing you plug into — is slightly out of spec, preventing a full insertion. Simply unplugging it and plugging it back in firmly can sometimes fix the problem. Remember not to unplug and re-plug the cable too quickly though, as it takes the device and charger a few seconds to negotiate how to charge and replugging the cable over and over again too fast can risk damage.

Try flipping the cable

USB-C is universal and doesn’t care what orientation it’s plugged into the device — except when it does. Sometimes the device or charger can become confused, which can be fixed by simply reversing the cable. While this may not fix your problem, it’s worth a shot.

Try unplugging the charger and cable for 30 seconds

Yup, I’m telling you the same thing your work IT support is telling you: Did you try turning it off? USB-C chargers and devices are “intelligent” and negotiate what charge rates to use when plugged in.

Sometimes the charger or device can become confused, which results in the charger not providing any power at all. Unplugging the charger from the wall as well as the cable and waiting for it to fully discharge and reset (say 10 to 15 seconds) can be enough to wake the charger up to provide power again.

Unplug other cables and try different ports

If you’re using a multi-port charger, remove all of the other cables from the charger except for the device you’re trying to use.

Multi-port chargers can become confused trying to juggle the different voltage requests from different devices. I’ve also seen multi-port chargers provide less power to each port just by having additional cables plugged into them that aren’t even being used, and some refuse to charge at all depending on which port the cable is plugged into.

Some multi-port chargers configure outputs in ways that simply make no sense and read like an algebra test. For example, an Anker 336 three-port charger I picked up for a song and a dance at Costco would charge my laptop with the USB-C cable in the third-port, but not the second port.

If you’re having problems, pull the other cables not being used while troubleshooting and try the other ports. One word of caution: It takes a few seconds for the device and charger to negotiate how to charge and I don’t recommend switching ports too fast. Give it a 5 or 7 seconds before unplugging and plugging it into another port.
