Why does my portable charger keep turning off

Portable chargers are a great way to ensure that your portable electronics stay charged no matter where you are. However, some find that their portable chargers keep turning off. If this is happening to you, you might be wondering why. If you have already tried turning your device off and back on without success, there could be a number of problems at play. 

There are two different situations in which you might find that your portable charger is turning off. These different situations point to different causes, so it is important to figure out which one applies to you.

If your portable charger turns off when you charge it:

Begin by determining whether or not your portable charger is working. If it cannot supply power to a cell phone, this may indicate an internal problem that will require a professional repair.

If your portable charger keeps turning off while you charge it, several issues might be the cause, including:

  • A faulty charging cable. Check to make sure that your charging cable is not loose or broken. If it is, then you should replace it in order to keep your portable charger working correctly.
  • Debris in your charging port. Inspect your portable charger’s charging port for lint, dirt, and other debris. If you find that your charging port is dirty, clean it and try charging it again.
  • A problem with your power source. Use another device to see if your power source is working. If it is not, try a different power source.
  • In some cases, a portable charger will turn off when it is fully charged. This happens so that your device does not overcharge, and is part of the product’s design.

If your portable charger turns off while being used to charge another device:

This second situation can be particularly frustrating if you are out and about. If you are trying to charge a device with your portable charger, but find that it keeps turning off and failing to deliver a charge, consider the following possibilities:

  • Certain devices do not draw enough power for the portable charger to register that it is connected. This might cause it to turn off because it is not in use. There are other portable chargers that offer a low-current setting. Depending on the devices that you intend to charge, you might research portable chargers with this feature.
  • If the device that you are trying to charge is broken or defective, your portable charger may not supply it with any power. Again, your portable charger might turn itself off because it does not detect your device. Check if your device can be charged by a different charger. If it cannot, it is likely that the problem is with your device, rather than your portable charger. 
  • If your portable charger is turning completely off, it might not be fully charged. Make sure that your portable charger is charged before you attempt to use it to charge another device.

If your portable charger is on but failing to deliver a charge to your device, check for these two potential problems:

  • Just like in the first situation, a cable may be faulty. In this case, this will be the cable that connects the device that you need to charge and your portable charger. Make sure that this cable is not loose on either end or broken anywhere. If it is, replace it with a working charging cable.
  • Again, there could be debris in either your portable charger or in the device that you want to charge. Check the ports on both devices for lint, dirt, and other debris. If you find any, remove it and try charging your device again.

After ruling out the above possibilities, you might find that your portable charger keeps turning off. This suggests that your portable charger has received internal damage. This can happen if your device is dropped, gets wet, overheats, or has a manufacturing defect. 

Unless you are a trained professional, do not attempt to fix these problems at home. Instead, contact the company from which you purchased your portable charger and see if the problem is covered by a warranty. If it is, your device may be eligible for a replacement, refund, or free repair. 

If it is not covered by a warranty, take it to a professional who knows how to repair electronics. Remember to always exercise care when handling electronics. Do not attempt to repair your own electronic devices.
