Telephones became very common and solved the communication problem. Now the problem of charging smartphones and other portable devices is brewing. Chargers and devices to replenish the charge on the device’s batteries are not always available. Every year, global companies patent new ways to charge phones that do not require an outlet. Now you can charge your phone without an outlet in many ways and in any conditions. The devices are very diverse and amazing.
Powerbank
The most common portable charger is a power bank. This is an external battery that is compact and lightweight. You can charge absolutely any gadget from it if you have a suitable adapter.
External batteries come in different types, with individual characteristics. The main parameter is capacity. The larger it is, the longer it will be able to provide electricity to the phone. The number of permissible charges will depend on it. Portable phone chargers can keep your smartphone charged for days.
Power Bank - simple, big battery
The most popular way. Having a large battery can support one or more devices with periodic charging for some time. But how much charge can be stored in a Power Bank? In advertising of this or that product you can find a value of 50,000 mAh or even more. Is this possible? Of course not. Open the hood of any car and look at the capacity of the on-board battery. 40-70 A/h, which corresponds to 40,000-70,000 mA/h. Yes, the voltage of a car battery is 12 Volts, and the output of a Power Bank is 5. But the capacity cannot be compared when weight and size are considered. Thus advertising lies. A regular camping Power Bank cannot have a capacity of 50,000 mAh. The most realistic thing is that the best Power Bank models assembled on Li-Pol batteries will have a capacity of 7000-15000 mAh.
How many times can a modern smartphone be charged from such a device? The average battery capacity of a modern phone is 3000-3500 mAh. You can easily calculate that you will be able to charge your phone 2-4 times.
Solar battery
Battery-free calculators powered by solar energy were once popular. Portable phone chargers work on the same principle. The solar battery operates efficiently all day long.
The device can fully charge a phone in 5-10 hours under high solar activity. If the sun shines weakly, it will take longer, approximately 15-18 hours.
Solar panels can be incorporated into any item of clothing or umbrella. This will increase the usable area of the battery and make charge accumulation faster.
Pros and cons of wireless charging
The strengths include:
1. Any charger created using the Qi protocol (at the time of writing, all models on the market use this standard) fits the iPhone and works correctly and safely. A good addition would be support for the Apple MagSafe standard (only for the iPhone 12 line).
2. Extending the “life” of the Lightning cable due to reduced wear during operation. User experience: all you need to do when there is an incoming call or SMS is to pick up the mobile phone and answer, there is no need to remove and connect the cord again and again, which often leads to premature failure;
3. Convenience, in particular:
- the usual location on the table or bedside table, so there will be no need to search (the same cannot be said about wires that always disappear somewhere);
- acceptable charging speed (subject to using MagSafe-enabled devices);
- can be used in different situations, including car holders with built-in Qi module.
Weak sides:
1. Inability to charge and use iPhone at the same time. With the exception of watching video content or using it as a navigator on chargers in the form of a stand.
2. It is inadmissible for objects made using metal to be located in the area of receiving and transmitting energy. This also applies to magnetic holders - their use involves installing a metal plate on the back wall of the iPhone.
3. Inferior in speed to fast wired charging (from 18 W) with Quick Charge support (more about fast charging iPhone).

Manual dynamo charging
An interesting solution for charging a smartphone is a dynamo machine, which is convenient to carry with you. It converts the physical force applied while turning the handle into energy.
To send an SMS or have a brief conversation with your interlocutor, you will need to continuously spin the machine for about a minute. To fully charge the phone, you will need to turn the handle for more than one hour.
On a note! There are special dynamos that are mounted on a bicycle wheel. Thus, when driving 10-12 kilometers, you can quickly charge your phone battery.
PocketSocket
PocketSocket is a small power station named after its owner. This generator has a single 120-volt outlet that can be plugged into a phone charger or any other device. We take the PocketSocket out of our pocket, connect the smartphone to it, turn the knob and watch the battery icon on the screen slowly fill.
The charging speed, of course, depends on the characteristics of the battery and the speed of rotation of the handle, but on average, in 1 minute the energy reserve increases by 1 percent.
A person using PocketSocket looks somewhat funny, and his hands begin to fall off after 10 minutes. Therefore, this method is not recommended for regular charging of a smartphone or tablet. Leave it as a last resort. If you find yourself on the street of a foreign city or lost in the forest and your phone dies, then PocketSocket will allow you to call your friends or call emergency services.
PocketSocket 2 from K-Tor is sold on the manufacturer's website for $65.
“The Last Cartridge” - a case for a AA battery
You don’t always have a charger with an outlet at hand. But batteries can be purchased on almost every corner. They can be used as a power source for your phone.
This portable charge is called the last cartridge. It is a case into which a AA battery or a whole block of them is inserted. Using a regular charging cable, the device connects to the phone and begins to power it. One battery is enough to replenish a few percent. It's better to use the whole unit to charge your phone.
Breathing mask AIR
The small mask incorporates the operating principle of a wind turbine. The generator rotates as you inhale and exhale. To charge your phone, you just need to put on a mask and lie down to rest or exercise.
During active activities, the phone can be recharged by 10-15 percent in 40 minutes. This charging device is economical, and when using it at night, you can completely abandon standard charging from a wall outlet.
