A power adapter is technically a converter of electricity from the wall outlet to the appropriate voltage and current that your device requires. What is commonly referred to as a phone charger consists of a whole unit made of a power adapters and a charging cables. The same power adapter used for one device can also work with other devices, but make sure it fits the voltage requirements of the device you are to connect to avoid damage or slower charges.

Although most chargers can be used on any mobile device due to the widespread use of standard connectors such as USB, the charger should still match the requirements of voltage and amperage of the specific phone. Using an incorrect power output charger may make the charging slower or may damage your battery sometime in the future. The original charger from the manufacturer should always be used, and only replacement chargers certified should get maximum performance.

When purchasing a portable charger for your phone, keep an eye on its capacity in mAh. At this point, you will find out the number of charges it can generate in the battery of your cell phone. Other important considerations are the type of charging ports available, if it supports fast charging, and how much weight and size does this charger come in so that you can just easily carry this around. In case you have more than one device, then a multiple-output charger would be really useful to you. Always ensure that the portable phone charger last for ages

The chargers may even trigger fires, posing extreme risks of overheating and short-circuiting. Often, such chargers will not have some basic safety features such as overcharge protection that can damage your mobile phone's battery. From low-quality materials and less-than-standard manufacturing processes, these chargers may not be reliable and are dangerous. The best solution would thus be to acquire chargers only from branded houses or from the point of manufacture for safe charging of your device.

You can charge your phone from another computer or any other USB port, but it's much slower than using a wall charger. The reason is that most of the USB ports are on a lower power setting, especially those in a laptop. Try to look for "fast charging" sockets, or use an original charger from your phone with a wall outlet when you can.

If the charger isn't working, try to check if it is damaged or if probably the outlet is working. Try to isolate for a different power source or another charging cable if it's possible. Clean the phone's charging port using a soft brush or a piece of cloth to remove dust or other debris that may be blocking the connection. Replace the charger or its parts with a certified manufacturer's charger.
