To achieve the maximum speeds promised by manufacturers, it is usually necessary to use a compatible charger and cable. When these accessories or an outlet are not available, some alternatives can help keep the device running longer.
Power bank is the most practical option
One of the best-known solutions is the portable battery, also called a power bank. The accessory allows you to recharge your cell phone practically anywhere and can be useful on trips, long journeys or days when the device is used more intensively.
There are models of different sizes and capacities. Even a compact power bank can provide enough power to prevent the smartphone from turning off before the user reaches a place with an outlet.
The disadvantage is having to carry another accessory. Depending on the size and weight, you may need to carry it in a bag or backpack, which is not always convenient.
A USB cable can also save your cell phone battery
Those who don't want to carry a portable battery can keep a USB cable handy. It allows you to connect your cell phone to different power sources, such as computers, some televisions, cars, trains and planes equipped with compatible inputs.
In certain public places there are also charging stations. The speed, however, tends to be lower than that obtained with a charger connected directly to the socket and compatible with the device's fast charging system.
Still, a few minutes of charging may be enough to keep essential cell phone functions available until it can be recharged normally.
Be careful when connecting your cell phone to unknown equipment
Using public USB ports requires attention. When connecting your smartphone to certain devices, the system may request authorization to allow data transfer or access.
If the equipment is unknown, the safest thing is not to grant permissions other than those necessary for loading. Authorizing access may expose information stored on the device.
Therefore, whenever a message appears asking if the connected device is trustworthy or if the user wants to grant access to the files, the recommendation is to avoid authorization when there is no certainty about the origin of the equipment.
Reverse charging can help without cables
Another possibility available on some smartphones is reverse wireless charging. The technology turns the cell phone itself into a type of charger for another compatible device.
In this case, simply activate the function and place the device that needs power on the back of the cell phone that will provide the charge.
The feature does not replace a conventional charger and typically offers lower speeds, but it can be useful in emergency situations, especially when there are no cables, sockets or power banks available.
Knowing these alternatives can make a difference when the battery is running out. Power bank, USB cable and reverse charging have limitations, but can guarantee a few extra minutes or hours of use until the cell phone can be connected to a suitable power source.
Cell phone gets too hot when charging? See adjustment that can solve
Some Galaxy phones allow you to turn off fast charging in the battery settings. The change increases the time needed to complete the charge, but may be useful for those who notice frequent heating during the process.
