Many people are possibly troubled with a problem that although there has been a big rise in smart phone's configuration, the technology in battery has remained stagnant. But fortunately, the development of external battery can help with our problems to a large extent. When travelling, tourists with a portable external battery charger can recharge their phones or other portable electronics at any time or any place. Gradually, external battery has become a very important accessory, and the products with varied promotions in the market have also been various. Then in the bombing of information, how can customers keep a clear mind in buying their ideal external batteries? 

There are three common mistakes in choosing the external battery.

First, the bigger the capacitance is, the better it will be. The volume of battery is measured by its capacity. More power it contains, bigger it will be.  
Therefore, when choosing, the type of battery is according to our needs. There is no need to take a "bricks" with you unless you travel often. In addition,the immoral phenomenon which some manufacturers deceive customers with high capacity, but actually, the capacity of the product is much lower than labeled. So the selection of factories should also be taken into consideration.

Second, the higher sales of products, the better quality it will have. The products from network channels, due to their price advantage, are often more able to attract consumers to buy. There's a common feature among the highest-selling external batteries in Taobao, which is the large capacity and low price. And it has already ranked the first or second in consumers' consideration. But in fact, these popular products may not stand the test of power quality. In short, consumers should measure the products from durability, safety, efficiency, appearance and other aspects, the popularity is just one of the reference. 

Third, if there will be any damage to the mobile phones or other electronics from using the external battery.
In fact, the same as the power adapter, no damage will be caused to the equipment. But if your external battery comes from those illegal-runned power bank factories, it is impossible to provide a stable voltage and current. It will damage your electronics. So as to protect the safety of equipment effectively,the search of information is necessary.

One winter, when I was a senior and was about to begin my intership in my hometown, my boyfriend, who used to be very stingy, suddenly said that he would give me a very precious gift. I was curious but also looking forward to it. Sitting in a classroom and wondering what the so-called precious gift will be. After school, I did not go back to the dormitory but directly went to my boyfriend's working place. When I found that the gift in front of me was the most popular and high-end mobile phone-Iphone, my tears immediately filled in my eyes. My boyfriend was said to be stingy is my way to ridicule him. My boyfriend and I were in two different cities, but in order to get together, he gave up the work with a high salary and came to the city where I was studying. All start again in a new city is difficult. For a quite long time, our money is only available for our clothing and housing. The appointment between lovers like watching movies or going to the coffee shop, were almost our schedules. Let alone sending roses or dolls.

This hard experience, however, highlighted the preciousness of that gift of that day. He said: "You will leave this city and begin your internships in another city. So we are going to have a very long time that we
cannot be together. This phone is very convenient and practical. The most important thing is that it can communicate with others by video call, so we can still see each other after you leave. "

A week later, I took the train home. Before I went on the train, he silently put a small box into my bag, I asked, "what was inside," he said, "It is not the right time to open it. " The train started, looking out of the window and thinking of those hard days that we live together, I took a look at your gift which warmed my heart tenderly, I decided to open the video calls at once. Looking at his face in the screen, it feels like that he was still around me. However, the good times didn't last long. After using the video call for a period of time, the battery soon ran out of power. But there were nearly ten hours before the train got to the destination,
and it would become much more inconvenient that I could not come into contact with my parents. No power of mobile phone made my journey suddenly become so helpless. I sent messages to tell him about my trouble. He soon sent back. He said "Do you remember the small box that I put in your bag? You can open it now." Unzipped my bag and opened that box, I was greeted with the words Iphone External Battery. My tears could not help felling again. I said "Your care is always so meticulous." He sent back in a joking tone, " the word are so cheesy that you'd better speak to the power bank manufacturer."

Connecting the power with my phone and looking out the window, out of which, the shade of trees was passing hurriedly. The words you said just now was emerging in my mind, "If you like fashion, I'm your battery with power bank 5000mah; if you prefer convenience, I'm your 6000mah external battery; but the same as 20000mah external battery, I will always be your side to provide you with the energy of love."

If we do a research to survey how many people are using power banks or external batteries, we can imagine that the number of people who don't use external batteries is minor. Yet, people mainly have two exactly different ideas of using this popular product. What's your opinion about using an external battery 10000mah? Let's see what pros and cons of it.

Pros:
In many cases, using a power bank has the following benefits: 
First, humanized design, easy to carry
Second, portable, rechargeable, and universal power bank 20000mah
Third, elegant and executive designed make it looks fashionable and smart
Fourth, package with two switched connectors, you can power and recharge your mobile or PDA, iPod/iPhone/iPad, PSP, MP3/MP4 players, digital camera and other mobile devices anywhere
Fifth, flexible recharging of power pack via notebook USB port or wall adapter with USB charging cable
Sixth, automatic recover function for your battery capacity of mobile phone or other device
Seventh, meet all related safety standard, have CE, Rose and FCC certificates

Cons: 
In a way, a power bank can actually shorten the life of the battery, the article does not match the size of the voltage between the power bank with the smart phone. Relatively heavy weights for some power bank which has a large capacity, and some species have to be operated with the support of the USB cable. Mobile phone or smart phone battery faster heat time in charge could damage the SIM card if it is too long or too often use the Power Bank.

A good portable external battery charger is necessary for us, especially the multifunction one. Most of these devices rely on an internal rechargeable battery for power. Functionality is lost when the battery is discharged. To meet the need for recharging these devices when a wall outlet is not convenient, a growing choice of portable external battery charger is available. These provide auxiliary power to recharge or operate your device. Most have the versatility to charge a range of electronics, but some are designed for specific items only, like the iPhone.

The different types of portable chargers can be divided into self powered and externally powered units. Self powered chargers include a hand crank and solar units that derive electricity from kinetic energy of the sun. Externally powered units may have a battery pack or need to be plugged in, but remain small enough to be easily portable. These portable charger will often have a built-in handle to facilitate transportation.

All portable power devices can recharge a cell phone or music player, but relatively few can recharge a laptop battery. Smartphones fall in the middle. If you own an iPhone, Droid or Blackberry, do some research to make sure you select a portable battery charger that can do the job,such as Iphone External Battery. Most electronic devices that can be charged via a computer USB cable need a charging source with a 5V output rating.

After ensuring that the portable battery charger is compatible with all of your devices, check the device for safety features. A good charger will have built-in overload protection to make sure that the devices are never overcharged, sent too much electricity or short-circuited. These safety features are important and can prevent permanent damage to expensive electronics. In addition, these safety measures can alleviate any concerns about fire hazards that are possible with incompatible or inferior chargers. Keep in mind that the chargers some companies advertise as being able to fully charge your electronics in under an hour may be unsafe or potentially damaging.

I have worked in the new company for a few months and lived a busy life. As a responsible secretary, you need to be on call for 24 hours. However, you have no idea that a little power bank could decide your promotion and change your career.

It was 7:30 a.m and I was sitting besides our company’s CEO in the client’s office. Four hours ago I was sleeping in my sweet bed. At midnight, I suddenly received a phone call from my boss that I had half an hour to get myself ready to go for a business trip with our CEO and him. Therefore, I dragged myself out of bed and packed some clothes, files, laptop, power bank 5000mah and other daily stuff. I took a taxi to the airport and waited for them. About 4 a.m, they arrived at the airport and we got on the plane very soon. On the plane, we got an email from the client and he said he wanted to talk with our CEO on the phone after we got off the plane because there was an emergency. The problem was that our CEO’s phone nearly ran out of power and those secret files were only in his phone. We could call the client, but we didn’t have those files. Our CEO was worried about how to explain to our client he might not call him on time. 

My boss told me that we did not have enough time to find a place to buy a new power charger, which occurred to me that I seemed to bring my 6000 mah external battery with me and it could be useful. After we got off the plane, I gave my power bank to the CEO to try whether it could help him to call that client. Fortunately, it worked well and everybody was happy for this, our CEO, my boss and that client. I was happy too as the CEO thought that I was a good secretary with chariness and he wanted to promote me as his personal secretary. Actually, power bank is a small thing but it has great usage especially for those people who always go for business trips and use phones to contact customers every day. Don’t underestimate its effect; sometimes it will offer you an unexpected reward.

The growth of smart devices in the world continues to increase, both users of Android, Blackberry, and IOS. But unfortunately, these smart devices are very greedy in energy consuming battery. Given these conditions, the solution appears power bank or battery backup to deal with running out of power at the time found no outlet.

Capacity will determine how time power bank can be utilized to charge our gadgets. Certainly POWERBANK with real capacity, real output and suited our needs.The power capacity If you want to buy old type power bank, you should know that maximum battery that can used for power storage is. If each battery has 2.500 Mah than the maximum number that we get is 7.500 mag.

According to the battery cells of the mobile power, it can be divided into four types basically: nickel metal hydride battery cells, lithium iron phosphate battery cells, liquid lithium-ion battery cells, and lithium polymer battery cells.

Nickel-metal hydride battery cells and lithium iron phosphate battery cells has low voltage and big nominal capacity, but the actual output efficiency is low. Compared with the lithium-ion battery cell and lithium polymer battery cell, they have no advantage. If the product description indicates this kind of battery cell, don’t choose that.
For power bank that using power bank 20000mah is a rational number and still make a sense. For full charge the power bank that has 20000mah need at least 12 hours. In normal condition, it could stand for a week.

The reason that mobile power gives out is that in the process of using, part of the battery energy cannot 100% output, part of it will be consumed in the form of heat in the internal circuitry of the mobile power, the higher the efficiency, the lower the heat will be, because of the energy losses in the circuit is less. Of course, the fever will also bring some serious problems, such as: thermal short-circuit combustion, high temperature accelerates aging of components. 

Guangzhou Sunwith Co., LTD, power bank manufacturer, is the subsidiary company of Global Vision Group (HK) limited. We are a professional and famous power bank manufacturer and exporter in China.We found the external battery division to solve this matter. Soon after, we lunched the external battery and Iphone power bank with fashionable designs, reliable quality and competitive price. At present, our product line has been expanded from the battery charger to mobile phone cases and accessories which are suitable for iPhone, iPods, iPad, smart phones, digital tablets and other portable devices.

The real development of external battery is in 2011. Many of us call it phone mobile power. But who knows that external battery was not invented for mobile phones? With the increase of smart-phones, a large number of mobile powers were lacked. People love to use Iphone so it's possible for them to buy an Iphone external battery.

Only a few people know when the first external battery appears. Mobile Power first appeared in 2011 CES (the Consumer Electronics Show). CES is held annually in the United States, which is the world's largest trade fair of consumer technology products. You can find any types external battery there, such as 20000mah external battery , external battery 10000mah.

In an obscure corner, a student used a few AA batteries and then pieced together with a mobile power control circuit to give the presentation of charging for digital products. At that time the "external battery" even did not have a shape. That is a circuit board, a few USB and a few batteries. You can see clearly inside. Today's external battery is colorful and attractive. Even one such an obscure corner, some people discovered it and then many people follow it. Finally the businesses of external battery were a great success.

External battery is a new charge which has power supply and charging functions. Digital equipments can be charged or standby or power whenever and wherever they want. Generally speaking, it is made by lithium batteries or a dry battery, and it is also called portable power.

In 2010, the smart phone and tablet (Iphone, Ipod, Ipad, Sumsung, Motorola, blackberry, Nokia...) developed tremendously.

Whether phone or other electrical battery, battery maintenance is the same. Maintenance of nickel-metal hydride battery, lead-acid and lithium ion regardless of mobile and fixed, nor sub-brands or manufacturers.
The loss of speed and battery life depends on many factors, the quality and capacity of the battery is very important, as well as the intensity and frequency of use, maintenance if properly will affect battery life.

Avoid throw touch, especially careful not to squeeze. Electrical products has always been not withstand the kind of throw touch,portable external battery chargers are no exception. A small mobile power battery is actually a complex device, throw touch or squeeze at any time may break inside the components, especially some people like to readily power on the move under the seat or on the nightstand, pressing books by various magazines, please note that this is very easy to damage the mobile power batteries.

Note that the temperature and humidity. Surely we have had this experience, if the weather is wet, especially back to the south, home to the TV one open, the screen is a little blurry, colors will be distorted, and this is the impact of humidity for appliances. Of course, mobile power is no exception, so try to avoid extremes of temperature and humidity are too mobile power storage environment, if there is more humid weather situation, you can use it more frequently, in order to charge it, so it is a good protection method.

Do not try to use fully charged. This is like the Iphone External Battery maintenance methods, cell phone batteries generally do not advocate the case did not finish the charging is interrupted use of mobile power is also true. Mobile power charger for mobile phone battery life first, before you move to full battery power supply itself, in the process, try to avoid the charge has not been completed is interrupted, as this also sacrificed its life.

As smart-phone’s bottleneck problem remains unsolved, external battery quickly becomes popular like "gas station". It is not only easy to carry but also has brought a steady of electricity which is supplemented for mobile phones. It’s loved deeply by consumers. But there are plenty of safety problems behind the popular external battery markets. It was a "sneak mine" and the product quality varies greatly.

There is a fact that even an external battery's appearance looks good, its inside could be made of an innovative, inferior battery cells, which is very easy to cause quality problems. The battery cells burn up, battery swells, its cruising power is short and even a little bit of voltage instability would cause serious safety issues. In addition, the cheap copy companies are good at fabricating a fake scalar and even some external batteries of big brand are the same.

Next is the circuit board. An excellent circuit board could maximize the.External battery's performanc. Otherwise, high quality batteries can not avoid an accident. Meanwhile, the special and excellent circuit design can protect the cells and reduce energy losses, which maximize cells energy to convert into electrical energy.

Furthermore, the circuit board also influences the stability of voltage and current. For the charging instruments, charging voltage and the current are required for a long time stability to make charging faster and safer. Additionally, protections are indeed. Such as overload, over-current, over charge, over temperature and short circuit.
