How to charge your phone using another phone?

We tell you how to charge one phone from another if there is no power supply or outlet.

How to charge a smartphone

In an emergency situation, when your smartphone runs out of charge any minute, another mobile device will come to the rescue. This method of recharging is very helpful if there are no outlets nearby. Naturally, the second smartphone should have battery reserve.

Without special devices, most smartphones do not have the ability to connect to another mobile device. To charge, you will need a standard USB cable and a special USB-OTG cord. This device is miniature and affordable. It will not take up much space in your bag, so you should safely purchase it and take it with you in case of emergency.

How to use a USB-OTG cord and charge your smartphone using another, procedure:

We connect USB-OTG to the phone from which another gadget will be charged.
We insert the USB cable into a connector that resembles the USB slot on a computer and discharged telephone.
The charging process starts instantly.

The magazine purity-en.htgetrid.com advises to pay attention to the fact that both smartphones must support the USB-OTG function. Sometimes you need to install the appropriate application.

Another minus — battery drain is much slower than from a wall outlet: on average 5% in 15 minutes. USB-OTG is not able to provide the same amount of current as the charger. Due to low power, not all devices can start the process.

Conclusion: You shouldn’t count on full results; you can only charge one phone from another by a small amount of percent.

A few tips to help charge your phone faster when there is no time to wait:

Do not use the device while charging.
Put your gadget on airplane mode or temporarily turn off data transmission (Internet).

Advice
In the same way, you can charge tablets and other gadgets from your phone.

Reverse charging

The latest models allow you to connect gadgets to each other directly for charging. These are smartphones like Samsung Galaxy s10+, Huawei Mate 20 Pro and other flagships of leading manufacturers.

Reverse wireless charging doesn't impress with its speed. In half an hour she squeezes out about 10%. But it's better than nothing, especially in an emergency.

Important
A smartphone that distributes energy loses as much charge as the consumer smartphone receives.

The mechanism of this function is the use of electromagnetic radiation. A field is formed between the two induction coils in the devices and charging starts. Interestingly, the function was originally intended to power “lighter” gadgets: headphones, smart watches.

Thus, with the help of a small cord and reverse charging, you can solve the problem with the battery at any time, being away from outlets and not having the original power supply with you. The only problem is to find nearby people with mobile devices who will be willing to share their charge and free time.
