In addition to the classic charger connected to a wall outlet, there are many ways to recharge the battery of a smartphone. Many of these systems are convenient when we are out and about or when we need a fast charge even without a wall outlet, so that we can continue to use the smartphone without fearing that the battery will run out. In this guide we will show you all the ways to recharge a smartphone, so as to be ready in the most disparate situations to supply charge to your mobile phone, even far from an electrical outlet (even if they are increasingly common in public places).
For convenience, we will also indicate the charging speed (slow or fast) next to each method, so you will know in advance how much charge you will be able to recover with the chosen method.
All the ways to recharge a smartphone
Below we can find a summary of all the methods to recharge a modern smartphone; obviously we will avoid recommending a classic USB charger, since it is included in the smartphone package and it is already the reference method with which we charge our mobile phone.USB socket on the TV (slow)
All smartphone power cables are USB type, so we can also connect it to the USB port of any modern TV (both Smart and simple).
These ports are present on the rear or side of the TV and support in most cases the USB 2.0 standard, not quite the best for charging a smartphone (it may take more than 3 hours to fully charge).
On some high-end TVs we can also find USB 3.0, much faster in charging times.
USB computer socket (slow)
If we often use the desktop PC or notebook, we can take advantage of one of the USB ports to charge our smartphone.
The charge will not be very fast, but at least we will avoid finding ourselves with the smartphone completely discharged during the break of our work shift or when we return home.
Wireless chargers (basically fast)
One of the most modern methods of recharging a smartphone is the wireless charger, which uses Qi technology to transfer electricity via electromagnetic induction. Obviously our smartphone must also be compatible with the Qi standard and the speed is also given by the induction currents supported (both by the smartphone and by the chosen charger).One of the fastest wireless chargers is the Anker PowerWave Wireless Charger (€ 21).
Once purchased, simply connect it to an electrical outlet and place the smartphone on the holder, so as to start wireless charging (always if available on the smartphone in our possession). We have seen in another article how comfortable wireless smartphone chargers are .
Recessed USB socket (both slow and fast)
We can add USB sockets directly to the walls of the house, by removing the sockets and replacing one of the electrical sockets with a USB charging element.One of the most used elements is the LEDLUX 2 Pieces USB 5V 2, 1A (19 €), compatible with the Bticino masks (sockets are also available for other manufacturers).
The charging speed will depend on the model chosen, but both slow USB modules (1.1 Ampere of current) and fairly fast modules (2.1 Ampere or higher) are available.
Charging stand (fast)
If we have an iPhone, AirPods headphones and an Apple Watch we can also consider a charging stand like the Seacosmo Stand 3 in 1 for Apple (€ 14).
This will allow us to recharge the iPhone, Apple Watch and AirPods headphones in one place, using a single power outlet. The charging times are comparable to the official charger provided by Apple, therefore fast enough.
Car charger (fast)
By taking advantage of the car's cigarette lighter, we can obtain USB sockets for fast charging, often even faster than the official wall charger.One of the best chargers for modern smartphones is the JOOMFEEN USB C Car Charger (€ 12).
To use it, simply connect it to the cigarette lighter socket and, when the engine is started, just connect a USB cable to one of the two sockets available to recharge our smartphone.
In this regard, we can read our guide Connect the smartphone in the car: support, music, speakerphone and charger .
Powerbank (both slow and fast)
Portable or powebank chargers are among the most used methods to recharge a smartphone wherever we are, even in the mountains or on the beach.One of the models we recommend you to buy is the Anker PowerCore Essential 20000mAh (29 €).
Just load the powerbank before departure or travel, so as to have an impressive energy reserve with a fast enough recharge and the possibility of being able to recharge the same device or several devices simultaneously several times.
Alternatively we can read our guide on How to keep the smartphone always charged (with portable batteries) .
Eco-friendly portable charger (very slow)
Speaking of portable battery chargers, we have also seen solar or crank battery chargers that do not require any prior recharging as it happens for additional batteries; one of the models we recommend you to view is the CZAING rechargeable solar energy battery charger with crank and radio (22 €).
When the charge is low, just turn the crank or use the solar panels to generate some electricity; obviously we do not expect fast recharges, since the conversion of muscle energy or solar energy into electricity is very low.
We can deepen the discussion in our guide Cover and Powerbank chargers for smartphones also with crank and solar .
Bicycle charger (slow)
For those who always ride a bicycle, a charger powered by a dynamo at the wheel is useful, so that while pedaling, the phone is also recharged. One of the few models available in Italy is the Kemo Electronic - Mini USB B smartphone charger (€ 30).
The current provided by pedaling is very slow: we will have to go really fast by bike to get a recharge of luck in situations where it is required.
Conclusions
We really have many different systems to recharge a smartphone, it's up to us to choose the one that suits our needs, considering that many of those seen above do not even need a standard electrical outlet.We try if possible to always choose the fast methods, so as not to regret the original wall chargers and get good recharge times (even if we do not always get 100% with luck refills, we can still extend the autonomy of our phone ).
In another guide we delved into the charger topic, talking about one of the most common doubts: You can use the same charger for all cellphones, smartphones, tablets and laptops "> Multiple USB charger to charge iPhones, tablets and mobiles all together .
