Phone chargers are used to power mobile phones. A charger connects to mains electricity through a plug, and a wire carries the electricity from the plug to the mobile phone. A charger is provided when you purchase a mobile phone, and replacement chargers can be bought at any phone store. Chargers can be opened in two ways, depending on the style of your particular model, but you should always take care when handling electrical equipment.
Remove your charger from the mains electricity. Switch off the electricity before you remove the plug to ensure your safety.
Video of the Day
Check if your charger has screws holding it together. If you cannot see any screws, your charger uses a seal that glues the charger together.
Place your charger on a flat surface. Use your screwdriver to remove all the screws from your charger. Pull the two pieces of your charger apart to open it.
Run a sharp knife or screwdriver carefully around your charger if it is held together with a seal. The two pieces of your charger are fixed with glue, so run the edge of your knife along the groove between the two parts to break the seal. Pull your charger apart to open it.
Things You'll Need
Always push your knife away from your body when using it to break the seal on your charger.
Make sure you switch off your electricity and remove your charger from the mains before you open it, to prevent an electric shock.
Be careful when using your knife, and avoid injury by pointing the knife away from you at all times.
