Read Time:5 Minute, 38 Second

It is not always possible to charge our faithful Android smartphone or iPhone with the original charger, since when we are traveling, in a meeting, or out and about, it is not possible to immediately find a power outlet to connect it to recover the charge lost up to that moment. . In these scenarios we can still keep the phone under charge using one of the alternative charging methods, so as not to arrive at the end of the day with the device completely discharged despite having the charger at hand.

In this guide, we will show you all the methods we can use to charge the phone without a charger so that we can equip ourselves in time and always have two or three of the methods mentioned in the car, bag, jacket, or backpack available. The prices of the devices that we will show you are not excessive, so it is better to immediately take advantage of them and choose what to keep on hand for a fast emergency recharge.

How to charge a phone without a charger

In the following chapters, we have collected the methods to charge any modern smartphone without the aid of a charger and an electrical wall socket. Some devices use the accumulation of energy with chemical processes (power bank and cover with battery), others use the energy generated by a running car but, if we are in the mountains or in a desert alone, we can also use more extreme methods to charging like solar cells or the strength of our hands (necessary to generate current from a dynamo).

Use a power bankHow to charge your phone without a charger

The simplest way to charge your phone without a charger involves using a powerbank, which can quickly charge any smartphone thanks to the energy previously stored. The first model that we recommend you to view is the Charmast Power Bank 10400mAh.


This power bank is light and compact, has two USB sockets to which two phones can be connected at a time, a capacity of 10,000 mAh, a control display, LEDs for the remaining charge level, and all modern fast charging systems (QuickCharge 3.0 and 18W charging ).


If we are looking for an even more capacious powerbank we can examine the AUKEY Powerbank.

This robust power bank allows you to connect up to 4 different USB devices, boasts a capacity of 20,000 mAh, 2 classic USB ports, and two USB Type-C ports, and an AiPower adaptable charging system, which allows you to get the maximum charging speed in the base to the connected device.

Use a battery coverHow to charge your phone without a charger

Another convenient and effective method to charge the phone without a charger involves the use of battery covers, which are thicker than normal covers that integrate an additional battery for our phone. Obviously showing you the battery covers for all smartphones on the market is impossible, but we can focus on the two best-selling phone models such as the Apple iPhone 11 and Samsung Galaxy S20 .

iPhone battery cover

Using this cover we will in fact double the battery life while also obtaining good protection from bumps and accidental drops. By connecting the iPhone to a USB cable, the smartphone will be recharged immediately and, as soon as the charge level reaches 100%, electricity will be used to charge the battery of the cover.

Samsung cover

With this cover, we will get an additional 7,500mAh charge, effective protection from all side impacts, a separate switch to turn on or off the additional charge, and bright LEDs, useful for understanding the residual charge of the cover. On powerbanks and battery covers, we can also read our guide How to keep your smartphone always charged (with portable batteries).

Use a car charger

When we are traveling in the car we can use the cigarette lighter port to charge our phone, so as to arrive at our destination with the phone fully charged or in any case with an adequate charge level to remain without a charger for at least half a day. If we want to equip ourselves in this sense, we advise you to take a look at the RAVPower Extra-Mini Aluminum 2-Door charger.

With this small device, we can get two fast-charging USB sockets (QuickCharge and iSmart) directly from the cigarette lighter socket or from the 12V port in the car dashboard, so as to be able to charge two phones at the same time.

AINOPE charger

This charger offers, in addition to the two fast-charging USB sockets (QuickCharge 3.0 and 36W), an LED indicator with the voltage of the car battery, really useful for checking in real-time if there are power problems while the vehicle is running.

Use a solar cell chargerHow to charge your phone without a charger

If we are in the mountains or hiking alone or with friends, we will hardly have access to a power outlet. In this case, it is worthwhile to focus on a solar-powered powerbank such as the Cocoa Power Bank Solare.

With this 25,000 mAh powerbank we will have all the energy needed to charge two smartphones (via the USB sockets provided) and, in case of emergency, it can be recharged with the photovoltaic cell on one of the two sides of the device. Two powerful LED torches complete the explorer equipment, in order to illuminate dark paths even in the absence of traditional torches.

If, on the other hand, we are looking for a solar panel dedicated to charging devices, we can view the CHOETECH Solar Charger.

Solar Panel

By placing this panel in the sun it will be possible to benefit from a device with a maximum charging current of 14W. Obviously, the performance of the device depends on the intensity of the sun’s rays, but thanks to the conversion rate of 25% we will be able to recharge a good 20% of the battery in about an hour of constant exposure to the sun.

Use a dynamo chargerHow to charge your phone without a charger

Effective dynamo chargers to charge our smartphone are hard to find, but luckily we can still find a good product online: Working Power Bank with a crank, available on Amazon for less than € 30.

This charger offers everything you need to charge your phone without a charger: a classic 10,000 mAh power bank, a high-efficiency solar panel, and a crank for the dynamo, so you can recover electricity even in the most extreme situations.


Even if charging the phone with the wall charger remains the best (and fastest) way, we will not always have an electrical outlet available; in these scenarios, a power bank, a car charger, a battery cover, or some extreme devices like a hand crank charger and a solar charger can really be useful.
