Charge your phone without charger

Your mobile phone battery is flat and you can’t recharge it by connecting it to its wall charger? I understand! With the intense use of mobile phones nowadays, often the battery charge does not cover a whole day: this means that when you are not at home or in the office, you risk being “on foot” and seeing your smartphone turn off without being able to remedy the situation.

Even if in some places, such as in airports or in some places, you can use the sockets made available by the latter, in most cases, when you are away from home, you need to find more practical solutions to be used in complete autonomy. In this regard, in this guide of mine, I will show you how to charge your mobile phone without a charger through some devices that allow you to restore the charge of your smartphone when you are not at home or in the office and there are no sockets available.

Power Bank

The first piece of advice I can give you to charge your mobile without a charger is to use a Power Bank.

These devices allow you to recharge mobile phones, tablets, and any other portable device on the go. Inside there are batteries that hold the charge and then transmit it to the devices that are connected to them, through the USB ports they are equipped with.

In general, the size of a Power Bank is similar to that of a smartphone, but it can also be smaller or larger. And if you are looking for a more advanced solution to get more details on the components of your computer, take a look at my tutorial on conclusivenews.com Since there are batteries inside, the larger its size, the more charge it can hold (and the heavier its weight too). That said, a Power Bank can be conveniently carried inside your bag or pocket.

Another fundamental parameter is the intensity of the current, measured in amperes ( A ), which affects the charging times of the devices. Typically, a USB 2.0 port has an amperage of 500mA, while a USB 3.0 port of 900mA. In the case of fast charging ( Qualcomm’s QuickCharge technology, just to give you an example, they can even reach 4.6 A. Obviously, to take advantage of these intensities it is necessary that the receiving device also supports these amperages.

Cover with battery

Similar to Power Banks are the battery covers. These products are nothing more than covers suitable for specific smartphone models with a battery inside that allows them to be recharged. The covers in question, integrating a battery, tend to increase the weight and size of the phone when applied.

Usually, the technical characteristics of these products are negligible, as they are calibrated for specific smartphone models. The only parameter you can evaluate is the battery capacity (expressed in mAh ), which indicates the number of charging cycles that can be carried out on the smartphone.

Some covers also have design features that can better absorb shocks in the event of a fall. In this regard, I advise you to read the technical specifications of the product well, check the materials with which it was built, and, above all, evaluate the reviews of other buyers, in case of online purchase.

Wireless charger

Another solution that could be for you is to use a wireless charger, instead of the classic charger. However, this kind of solution is not applicable to all smartphones, as wireless charging must be supported by it. Many smartphones, such as the latest models of brands such as Samsung and Apple, support this technology and it is possible to use this type of device to charge the battery.

That said, depending on the device you own, you can buy the wireless charger directly from the manufacturer’s website or choose the compatible ones. In the latter case, you must check that there is compatibility with the Qi standard of the WPC consortium, which is now used by almost all manufacturers of devices that take advantage of wireless charging technology. 

This standard is essential so that there is no risk of damage to the device, maintaining all those safety standards that can preserve the integrity of the device and everything around it (including people). I’ll tell you more about it here

Solar cell charger

Another interesting solution, which can be for you, is to use solar cell batteries. There are, in fact, chargers that fall into the category of Power Banks and have small solar panels that allow them to keep the charge of their batteries almost unlimited if exposed to direct sunlight.

Their operation is based on exploiting the electricity generated by the photovoltaic effect. The photovoltaic cell is composed of a semiconductor, such as silicon, whose electrons are “excited” in contact with direct sunlight: this process generates electricity, which is then stored in the batteries.

It can be a very practical object, for example in the case of excursions, as it is possible to position the panels of which it is made up on the backpack, allowing the recharging of its battery. Unfortunately, however, the electrical characteristics of photovoltaic cells greatly depend on the quantity and intensity of light to which they are exposed. For this reason, the battery in their possession, for the same time, may have a different percentage of charge
