Charging a gadget, be it a phone, tablet, bracelet, navigator or something else, has long become an obligatory daily ritual in life. modern people. But, unfortunately, constant use can lead to failure of chargers, because the wires break and the plugs break. This raises a reasonable question: “Is it possible to charge the phone with another charger?” On this question I will try to answer in this article.
Fortunately, most devices use the same charging standard
– this type of connector is used by Android devices, be it a phone or a tablet. Most Windows Phones also use micro usb.
Lightning– a universal type of power connector for Apple devices, it is used on iPhone, iPad, iPod starting from 2012; older models require a 30-pin connector, which is also universal for all devices older than 2012.
And if everything is simple with Apple devices, a single standard allows you to charge any Apple device with any charger from the same manufacturer. With devices with micro usb, it’s becoming more and more difficult; in order to understand what the complexity is, you need to understand 2 terms that will need to be emphasized in the future: Current (marked with the letter A) and Voltage (marked with the letter V).
Charging with a lower (higher) current intensity
USB according to the specification is designed for a voltage of 5V. This means you can connect any device with micro USB to a charger with this connector. But to be on the safe side, it’s better to look at the markings; it will only take a few seconds. But in 99% of cases, they are identical for each brand and manufacturer.
The main attention should be paid to the current strength, most tablets, for example, are designed for 2A (2000 mA), while phones, for the most part, consume 1A (1000 mA). You can find out the charging parameters for your device on the original charger, in the instructions, or on the device manufacturer’s website.
So what happens when charging your phone with low current? Nothing irreversible will happen; if you charge the tablet (which according to the documents consumes 2A) by charging from a phone with 1A, the charging time will increase by 2 times, and nothing will happen to the tablet. In the opposite situation, the device itself comes into force, it will consume the number of amperes it needs, almost all modern models phones are now able to limit the current to the level they need.
Charging from a computer
Charging from a computer's USB connector is possible, but it is worth considering that the current in this case is 500 mA (0.5A) and the charging time will increase. It is for this reason that charging the tablet from a computer or laptop while it is turned on is useless, since the energy consumption is almost equal to the charge level from the USB port.
Can Quick Charger charge other phones?
To begin with, I would like to say a few words about the technology itself, what it is and why: in short, phones with this function simply increase the voltage and current, thereby speeding up the charging process, while controlling phone parameters, such as the temperature of the phone battery, and protecting from negative consequences.
The video above demonstrates this function from one of the manufacturers.
And this means that a simple phone Can charge with a charger from a model with Quick Charger, since this function is built into the phone, and not into the charger itself.
Hi all! And especially for those people who have an iPad charger and who want to know - can it charge other Apple devices, such as an iPhone or iPod? Indeed, an unprepared and, more importantly, careful user has too many questions about this whole situation. And here are the most common ones...
Is the iPad adapter suitable for iPhone and will there be any harm from it? Will expensive products break? Will the iPhone work less on one battery charge? Now we will try to understand all this in detail on our own, and we will also receive an official response from Apple, which will clear up all misunderstandings and draw a line under this discussion. It's time to start - let's go!
But first, let’s clarify what are the pros and cons of such a solution? Pros:
- iPhone charging time is reduced. Despite the fact that the native charger in the iPhone is 1 Ampere, this was done mostly for reinsurance, because the device itself can take a little more.
- So as not to carry several chargers with you.
I personally did not notice any disadvantages and Apple agrees with me (more on this below), but judging by the reviews on the Internet, some users experience a slight increase in the heating of the device. Of course, this is if we are talking about original accessories. There will be more problems with non-certified ones - they won’t charge, won’t connect, etc.
But let’s return to the main thing, why does the question voiced in the title of the article even arise? Because the chargers for these two devices are still different. Moreover, both in appearance and in the strength of the output current. For iPhone it is 1 Ampere, for iPad – 2 Ampere (larger battery – you need a more powerful power adapter).
But is it possible to use it (the more powerful charger from the iPad) for constant charging? iPhone battery and isn't it dangerous? Of course yes. And here's why:
- The output voltage of all iOS device charges is identical and equal to the voltage in the USB port ± 5 W. What is stated in the specifications is the maximum current that it will not necessarily produce.
- Any Apple device has a special controller, thanks to which the iPhone simply will not “take” more than it should from charging the iPad.
By the way, here is a screenshot of Apple's official response. I think these guys can be trusted:
And finally, a little personal experience.
For many years I have not worried about this at all. I charge my iPhone and iPod (even Nano and Shuffle) with everything, including the power supply from the iPad. There were no problems with the batteries. The main thing is to use original accessories, but how and in what order to mix them is not important. But this is just my opinion :)
P.S. As I already wrote, there will be no problems, but it’s better to play it safe and “like” this article. Did you do it? Now you can safely charge your iPhone!
Apple technology users are often called family. And this is not without reason, because only when using a variety of equipment with the image of an apple do you really feel how different devices work together. Accordingly, with all this, you have a great variety of chargers at home. And, naturally, one day the question arises, is it possible to charge an iPad using an iPhone charger?
Functionality check
Let's start with the fact that you don't need to have a specialized education or the necessary knowledge in electrical engineering to see when inspecting the chargers of Apple devices that the chargers are visually simply different: the power supply from a tablet is twice as large as a similar accessory from a smartphone or iPad mini. But there are situations when it would be convenient to bring one charger to work and leave the second at home. So let’s figure out whether charging from an iPad is suitable for an iPhone.
No, of course, you won’t see such a picture if your charger and cable are original. By the way, you can also use non-original ones, just don’t buy who knows what: using cheap chargers (after all, most often Chinese), you risk ruining the battery.
Can I use the charger from another device?
A minute of technical information. Large chargers - for iPad - differ from power supplies for iPhone only in amperage. In the first version it is 2A, and in the second it is 1A. They all have 5 volts. Accordingly, the power is 10 and 5 watts.
But the maximum power of the charger is indicated. This means that it can be used to recharge any device that needs less power.
Control over electricity consumption lies on a special chip inside the gadget. It is clear that a more powerful iPad can “digest” more energy, and its controller allows it to consume more power.
Conclusion: you can charge your iPad and iPhone with absolutely any 5-volt power supply. But it’s worth considering that the tablet will take twice as long to charge using a phone charger.
The latest smartphone models running Android OS have begun to receive fast charging functionality. As for our favorite smartphone, this option is available to all iPhone and iPad users at the same time. This feature is not described anywhere, but simple experience shows that 1A standard current is far from the maximum value that a smartphone can use. By taking the power supply from the iPad and connecting it to the iPhone, we get about 25-40% faster battery recharging.
Is it possible to charge an iPad using an iPhone charger: Video
Each device: tablet, smartphone, e-book or laptop come with their own chargers. At least that was the case until recently. Nowadays, most modern smartphones and tablets have a Micro USB connector, and this is becoming a standard. Against this background, the question arises: is it possible to charge all your gadgets through one charger?
Despite the fact that over time more and more chargers are produced according to a single standard, several types of chargers are still widespread:
- Laptops. Unfortunately, we have not yet come up with a single standard for charging laptops and netbooks. There is no universal connector, which means that each device needs an individual charger.
- 8-pin connectors(lightning connectors) for Apple gadgets. Since 2012, Apple has standardized on the 8-pin connector, and now all devices released after that year: iPhone, iPad, iPod Touch, iPad Nano, can be connected using an Apple-certified and designed charger.
Older Apple devices have a 30-pin connector, and for those who still have them, Apple produces lightning to 30 pin adapters.
- micro USB chargers. All new smartphones, including Android and Windows Phone devices, come with a standard micro USB connector, so there is no need to select individual chargers for them, as for older mobile phones. To meet this standard, Apple offers Lightning connectors → Micro USB adapters.
Can I charge any device with a connector? Micro USB from any charger Micro USB?
In theory, every Micro USB charger can be plugged into a device with such a connector, which means it can be used for any device, be it a smartphone, tablet or even a laptop. Very convenient - if you buy new smartphone or tablet, you can charge it with an old charger. The only difference is the voltage and current, but more on that later.
You can also charge the device from a laptop using a Micro USB→USB adapter.
Dangerous chargers
The HP Chromebook 11 is the first laptop to use a Micro USB connector for charging. Most laptops require more power and cannot be charged this way.
But this laptop was also withdrawn from sale due to reports of overheating of the charger, which could cause a fire. An HP spokesperson advised users who purchased the HP Chromebook 11 not to use the original chargers that came with the device.
You can continue to use your laptop by charging it using one of the micro-USB chargers tested by Underwriters Laboratories Inc. (US Standards and Certification Company), for example, from a tablet or smartphone.
You will easily recognize chargers that have been tested and approved by Underwriters Laboratories Inc. - they have the “UL Listed” logo.
This means that the charger has been tested for safety and will not cause a fire or shock you. But in some cases, even proven chargers can cause trouble, namely when the device’s battery is faulty. So the cause of a fire can be either a non-original cheap charger or an equally cheap, uncertified battery.
Voltage and current
All USB connectors are designed for a voltage of 5V. This means that you can safely connect the charger to the device via micro USB.
Another thing is the current strength. To charge the device faster, chargers increase the current, which is measured in amperes (A). Chargers that come with Android tablets, are designed for higher current strength than similar devices for Android smartphones. For example, a tablet charger is rated at 2A, while a smartphone charger is only rated at 1A.
If you connect a smartphone charger to a tablet, the tablet will charge very slowly because there is not enough current to charge properly. If you try to charge your smartphone using a tablet charger, nothing bad will happen, and your smartphone will not explode or catch fire.
Most likely, the smartphone will not take the maximum possible number of amps that the charger provides, so everything will be fine. Maybe the smartphone will charge just a little faster.
Good day, dear readers! In this post I will tell you and give examples of how to properly charge your smartphone! All the details are under the cut :) Nowadays, every person, and even more so a geek, has at least three chargers in the house for their Android devices. But everyone...
Good day, dear readers! In this post I will tell you and give examples of how to properly charge your smartphone! All the details are under the cut :)
Nowadays, every person, and even more so a geek, has at least three chargers in the house for their Android devices. But all charges have a slight difference. A smartphone charger, for example, has a current of 1A, and a tablet charger has a current of 2A.
Most people have a question: is it harmful to charge a smartphone by charging from a tablet, or vice versa? And the main question is how to properly charge a smartphone? This question, of course, arises most often among newcomers to the mobile world. But still it takes place!
There are a lot of opinions about how to charge this or that device. Some people advise discharging the device’s battery to 0% each time and charging it to 100%. And some recommend keeping the charge between 20% and 80%. Complete discharge of the battery occurs if the battery is nickel, because nickel batteries have the so-called “memory effect”. But as we know, in modern devices batteries"lithium-ion", and such batteries do not have this effect. Thus, we immediately exclude the myth of “0% discharge” from our methods of charging devices :)
Which method, then, will be more gentle on our batteries?
— Recharging the device
The most gentle mode for the device’s battery is to recharge it regularly. Many people advise that the battery charge should not drop even below 50%. I would advise you to recharge the device every time the charge drops to 20%. It is best to keep the charge between 20% and 80%.
— Do not leave the device to charge “overnight”
As I said above, the battery-friendly mode is from 20% to 80%. There is an opinion that if you leave the device on charge “overnight,” this is what shortens the battery life. But this applies more to “no-name” devices (China). Since most official, branded gadgets have built-in controllers that control the charging/discharging current of the battery. When the charge reaches 100%, the controller opens the key and the voltage stops being supplied to the battery, to avoid overcharging. So leave it overnight and don't be afraid of anything!
— Discharging at 0% IS USEFUL, but not often :)
Yes, yes, exactly the discharge to zero. Although I wrote above that this is very harmful to the battery, it needs to be done once a month. Now I will explain why! All of our devices display the charge as a percentage; due to frequent recharging, this indicator will show incorrect readings over time. You can calibrate these readings in a simple way, discharging the battery to zero and fully charging to 100%.
— Keep the device in the refrigerator!
No, this is of course a joke about the refrigerator. But I must tell you that high temperatures shorten the life of the device’s battery. Those who have really wondered about the effect of temperature on lithium-ion batteries know that if you store it at a temperature of 20 degrees Celsius for a year, the battery loses about 20% of its total capacity.
— Is it possible to charge a smartphone using a tablet charger?
We all, including myself, have at least two chargers in the house. In my case, this is charging from LG Nexus 4 (with an output current of 1.2 A) and from ASUS Nexus 7 (2012) with an output current of 2A. And no matter how much I want to, I either charge the tablet using a smartphone charger, or vice versa. So let's figure out whether such interchange of chargers is harmful?
Opinions on this matter are divided... Some say that a higher current than in the “native” charger can damage the battery or even damage the device. Others say that it is completely harmless to the battery.
But personally, I believe that the “interchangeability” of chargers has its place, and nothing will happen to your devices. Why? Because, as I already said, each device has charge/discharge controllers and a battery controller. So this same controller will not allow the device to “take” more current than it needs. If, for example, a smartphone is charged from a “native charger” with a current of 1A, then from charging a tablet (which has a current of 2A), the smartphone will also consume the 1A it needs.
IMHO
Personally, I charged my Galaxy Nexus with an ASUS Nexus 7 (2012) charger for a year, and nothing bad happened. And now I use the same charger from the Nexus 7 to charge the LG Nexus 4. And I don’t worry about battery damage, or even more so, the device breaking down!
What do you, dear readers, think about this? Is it possible to “interchange” chargers from different gadgets in the house?
