4 Tips for Buying Power Bank
As the technology has improved so much, mobile phones are now common to see. Almost everyone around us has a mobile phone. However, compared to the conventional kind of cellphones, mobile phones seems more quickly to consume its power, which means, you can't use it for long without charging.
As a solution, the brilliant technicians came up with an idea : creating a portable power, which then named “power bank.” With a power bank, you no longer have to worry about the problem of power deficiency. That’s why power banks became more and more popular and widely used.
But how to choose a proper power bank? We’ve heard about many frightening accidents due to the explosion of power banks…is it really that dangerous?
Well…not actually, because it depends on many other reasons.
Here, I’m gonna tell you something about how to choose a safe and useful power bank.
1. Choose a well-known brand:
First, the easiest thing to do, is to choose a well-known brand. Though they are usually more expensive, well-known brand can be seen as a quality assurance. Because the safer it is, the more popular it should be. As a result, this can be a reliable index.
2. Choose a proper size:
This depends on how much power you need. Generally, as for a power bank, the price, size and the power load are proportional. Which means, the more power it can load, the bigger it will be, and the more expensive it may become.
A normal power bank can load about from 5600mAh to 10000mAh. And the usual power load of a mobile phone is about from 1400mAh to 2100mAh.
As for a tablet, it needs about from 4000mAh to 11000mAh.
Well…these numbers can still not represent the whole data. You still need to calculate some other statistics such as the energy conversion rate, in order to make a comprehensive evaluation.
3. About the "fast charge" power bank:
"Fast charge" means the phone can be charged at a high speed. But that’s not really something special. It just depends on the electric power of a power bank. The higher its electric power is, the faster for it to charge a mobile phone.
4. BSMI certification:
BSMI is a kind of certification thatguarantee the customers’ right. Especially about the electronic devices, BSMI has a veryhigh threshold. Of course, for the power bank, it also has a strict regulation. It mentions the power load, the electric power, and the energy conversion rate. This can be a promise of the safety and quality of the power bank you purchase.
Here’s the conclusion. If you want to buy a power bank, you need to evaluate carefully. After all, safety is always the major problem you need to concern. Don’t be captured by the low price! You will put your own safety into risk! That’s not what we want to see, right? So follow the steps, and choose carefully. Trust me, you won’t regret.
About bringing power bank abroad
It’s always a thorny problem that your phone is out of power. Especially, abroad.
You need your phone to serve as a GPS device, and you need it to communicate to someone who can help you. Without power, your phone is just useless.
What I’m saying is that, a power bank is extremely required when you’re at a different place. You just need to charge power bank, and then when you’re out, you can still charge your phone whenever you need.
However, there’s a serious problem. The transit inspection is something you need to concern about. According to the flight safety regulations, power banks that has the power rate over 160 watt/hr are not allowed to be brought onto the airplanes. And that’s still not the end. In order to prevent the danger, the power banks that has the power rate between 100 - 160 watt/hr, can’t have to be carried with the passengers.
How to Use a Power Bank?
First, you need to charge your power bank, just like you need to deposit your money into the bank first. You have to attach a phone charging cable to your power bank, and then connect to the socket. When the light of the power bank come on, it means that you’re charging it.
And when you’re gonna charge your phones with it, you also take up your phone charging cable, and this time, connect the power bank and your phone with it. When the light come on and then slowly decreased, it means the power bank is charging your device.
But here’s something important i'm gonna let you know. Do not use your phone when charging it with power bank! This is extremely dangerous! Many accidents are due to this improper move. The time your power bank is working is the most dangerous time, whether it’s charging a phone or it self. So you have to make sure you use your power bank at the place inside your vision, so that you may prevent many irreparable tragedies.
Solar Power Bank Charger Review
(1) What is solar power external battery?
It’s a kind of power bank that can obtain the electricity energy from both sun and socket. This is a very special feature that you can charge it at any place where the sun can can shine it light on.
(2) Is it practical:
Well...it really is able to charge with the sunlight───the solar power. However, it’s not efficient to charge it just with solar power, and what’s worse, the sun isn’t always there. After the sunset, the solar power external battery still can only charge with cables and sockets.
(3) Why consume power automatically:
It’s because of the overcharge protection mechanism. But don’t misunderstand! This is not a bad thing. Instead, it’s a protection preventing the power bank being overcharged. To the solar power external batteries, this can be annoying. Solar power external batteries can automatically obtain energy from sunlight. This can cause the problem of overcharging. So there must be some kind of protection to prevent this.
The overcharge protection mechanism will consume the power to make sure the power bank won’t be overcharged. But this can cause too much wasting of power, and still, there are many other parts consuming the power, especially the LED cue-lights. The LED cue lights will be turned on when it sense the sunlight, and that really takes much energy. The problem is, sometimes these parts will consume most of the power, and then your power bank will end up being out of power.
Should Potable Chargers be Recycled? or Directly Discarded?
We all know that batteries cannot be casually discarded. We have to recycle them. How about power banks? Should potable chargers be recycled? The answer is: Yes, Of Course!
Most of the mobile portable charger is made by the rechargeable lithium battery, so properly recycling is necessary.
Before recycling, you need to run out of the remaining power as much as you can; during recycling, do not disassemble or destroy to keep its integrity. Then, send it to used battery recycling station or store.
In addition, the electrode can be insulated with tape in order to avoid accident happen.
The Chinese Name of Portable Charger
Mobile portable charger, the English name for the different regions, cultural backgrounds ... in the words with great diversity, such as: power bank, portable charger, mobile power pack, etc. The Chinese name of portable charger is also with great diversity. Some of names are derived from the appearance, from the function, or have a deeper meaning. Let’s see some interesting and common Chinese names of power bank!
【 From the Function】
可攜式充電器〔kě xī shì chōngdiàn qì〕
“行動” and “移動” mean “Mobile”.
“可攜式” means “Portable”.
And “電源", "充電器” are “charger” in Chinese.
【Named From the Exterior】
尿袋〔niào dài〕- Because the appearance when the power bank connect with the mobile device looks similar with human who is using "urine collection bag". (That’s so interesting, right?)
In addition, the Chinese names of mobile portable charger are usually related with 行動(mobile) and 可攜式(portable). In order to emphasize the convenience of mobile power bank and it can charge mobile device immediately.
What is Lithium Battery?
The most important part of a power bank is its lithium battery. The lithium battery is just like the heart of a power bank, offering the power for the whole device. And when the time your phone is out of power, the power bank can offer you the power to charge your phone.
Lithium battery is a special kind of battery. It contains lithium elements, and uses its chemical properties to transform the chemical energy into electricity power. The good thing is, this kind of batteries can last for over 10 years. As for the mention of environmental protection, it doesn’t cause great harm to the environment.
However, lithium batteries can lead to something extremely dangerous...chemical explosion.
Because of its high activity, lithium can easily brings violent chemical reaction. All what it need is a little bit irritants, and then it explode. Well known brands are working hard on dealing with this hazardous chemical property. But the other unidentified factories won’t concern about this. Instead, money is the only thing they want. So they just hastily produce tens of thousands of lithium batteries and power banks, and then lower the price to attract the naive customers. These power banks they produce, are surely, and extremely dangerous. Just a little bit crash can make them explode.
Sounds like lithium batteries are not really safe. Then why we still use them?
Because we haven’t found something that can replace lithium. As a result, the only, and the most important thing to do, is to make sure you buy a certified product.
As a result, official certifications are required. An official certification in Taiwan called BSMI, can be a reliable assurance. BSMI has a high threshold for the electronic devices, including power banks. So when you’re looking for power banks, you can check if it has a BSMI certification mark, then you can make sure you buy a safe power bank.
But still, remember, even the certified power banks have the risk of explosion. So you need to use it in the right way and maintain it properly.
Here, we present you some tips about how to keep your power bank safe:
(1) Don’t put it in a high temperature environment. Don’t expose it to sun.
(2) Keep it dry. Don’t let any single drop of water contact it. Water can cause short circuit.
(3) Don’t crash it or smash it. It will damage the inner components.
(4) Always keep it inside your sight when you use it. Keep your eyes on it, then you may be able to prevent the tragedies.
(5) Whenever you find that the battery, or even the whole power bank has deformed, for your safety, please don’t use it any more. Recycle it and buy a new one.
How long a power bank life period?
What? The warranty period is one year only?!
Don’t be surprised! According to each user's usage habits and frequency, it will lead to differences in the length of life period of power bank. And the one-year warranty period is based on the average life span of new power bank.
Of course, if the portable charger is made by recycle one or second-hand goods, its quality might be worse, so when you are buying a power bank, most manufacturers do not provide product warranty or only a short-term warranty period.
If the manufacturers dare to provide long-term warranty, it means that they care about their goodwill or have faith about their products. So purchase power bank from there has more guarantees!
How long of usage is time to discard?
In general, the life time of the new portable charger is one to two years. According to the experimental data of foreign countries, the "excellent" lithium battery can be recharged more than 500 times. However, even if no problems occur, regular replacement is recommended. Buying a cheap power bank is penny wise and pound foolish, so don’t let mobile charger turn into mobile bomb!
Power bank charging problem: Do you have?
I believe many my friends have encountered such a problem: why I already charged power bank for a long time but it still cannot be full energy?
To exclude the failure factors actually are very simple. If you have this problem, just need to test 1. Batteries 2. Circuit board 3.Charging wire one by one.
As a general consumer, if the battery or circuit board has problems, usually because the product is defective or usage is inappropriate (for example: high temperature, collision ...). If so, it is recommended to directly discard it and buy a new one.
In general, if the mobile power supply cannot be recharged, mostly due to wire and adapter failure, so please check the wire and adapter first.
Because of the circuit board power protection settings, continuous charging is necessary. If the charging cable or adapter is broken or disconnection, even you let it charge for a long time is still no work. (Go to check the wires in the house!)
Have strange smell during using portable charger!?
Have strange smell during using portable charger which you just bought recently!?
The power supply has a strange smell because the electronic components and welding parts inside contact with high temperature will generate the gas which has strange smell.
Usually, after two to three times of using, the situation will naturally reduce, so do not be worry.
However, if you smell the burning smell, insurance, please stop using it immediately!
Before buying a power bank, you should know that: Recognize the types of battery core
These four types of batteries are common to see in our daily life: 1. Ni-MH battery 2. Ni-Cd battery 3. Lithium-ion battery 4. Lithium polymer battery.
Ni-MH battery and Ni-Cd battery are often used in home appliances. Moreover, because of the high efficiency of recycling, they are also common as environmentally friendly batteries.
However, this type of battery has a memory effect, that is: the first use must be a complete charge and discharge. Why aren’t they widely used in mobile power bank?
The main reason is that the functionality of the mobile power supply itself is to emphasize the immediacy; it can immediately rescue the mobile device which runs out of power. This high frequency of use, for Ni-MH battery and Ni-Cd battery is undoubtedly a fatal problem which makes their life span shorter.
On the other hand, such batteries under the improper using way, they might have more doubt about explosion. Therefore, in the choice of power bank battery cell are mostly lithium-ion battery and lithium polymer battery.
Lithium-ion batteries and lithium-polymer batteries, which are collectively referred to as lithium batteries, have the characteristics of no battery memory effect, so they do not have to have a long time charging when they are used for the first time.
But these two kinds of batteries still have somewhat different! The biggest difference between the two is that the electrolyte inside the lithium polymer battery is colloidal. It makes the improvement about the exposed problem. Even it has short circuit happened, the battery will only expand but not explode. Besides, its appearance can have more variation!
Therefore, in the choice of portable charger, the lithium polymer battery is better recommendation to choose. Not only higher security, in appearance and shape, it is higher potential than the lithium-ion battery. However, it also means you need to cost more money to get them, just make your choice.
Before buying a Power Bank, you should know that: What is Battery Memory Effect?
The battery memory effect refers to the rechargeable battery which reduced its capacity because it often is charged before running out power.
This situation often occurs in nickel-cadmium batteries (NiCd) or nickel-metal hydride batteries (NiMH), such as the old phones which used these kinds of rechargeable battery. So you might familiar that someone reminded you, “The cell phone MUST be charge 8 hours before you use it.”
However, the above situation is the past time (the cell phone battery was nickel-cadmium or nickel-metal hydride batteries). Nowadays, Most of smart phones and portable chargers′ batteries are lithium-ion battery (Li-ion) or lithium polymer battery (Li-polyment).
This series of lithium battery is no doubt about the battery memory effect. They are more match users’ daily needs and habits, no wonder they can replace the old rechargeable battery to become the most widely used species.

What Should you do when you Have a Swollen Battery Portable Charger?
Currently, on the market, portable chargers, smartphones’ battery use lithium batteries are common. This kind of battery doesn’t have battery memory effect. Furthermore, instead of explosion, the lithium battery just become swollen even short-circuit happened. Swollen lithium battery can still be used, but its storage capacity, performance, etc. will be greatly reduced. Besides, the battery resistance will increase, if you continue to use it, it easily lead to high temperatures, and increasing the risk of burst. According to well-known University Department of Electrical Engineering professor said “The swollen lithium battery will produce carbon monoxide, phosphorus and other toxic gases. These gases are no odor so difficult to detect by ourselves. If in long-term inhalation, it might damage human’s body.
In short, if you notice a portable charger or other electronic product has swollen battery problem, please stop using it immediately and recycle it properly.
What is the Reason that the Portable Cellphone Charger not Working?
What happened that a portable cellphone charger didn’t work when you were charging?
First of all, please confirm whether the power bank still has power, or it doesn’t be discharged / overcharged and cause the protection mechanism starts. Then, please confirm that the charging transmission line is connected properly, whether has damage or connection problems or not. Recommend you to test several different devices to charge with the charging transmission line. If there is no problem, please confirm whether the transmission line and your phone have rejection phenomenon or not (occasional problems, such as Apple company products, the extreme exclusion of non-original peripheral products, we recommend you use the original transmission line to charge your phone because it’s relative with the power supply software and mobile phone software!).
Whether electronic products or daily necessaries, you get what you pay for is an observation that never changes. Buy power bank, choose the one which has security check or product warranty is the best to protect you!
Can Portable Phone Charger be Repaired?
Portable phone charge can be fixed. However, the mobile power supply is a consumable product, and if you use the bad one continuing, it also has doubts about the explosion. Furthermore, the cost of repairing power bank and buying a new one are almost the same. So, in generally, people would rather buy a new one and will not repair! If the power bank itself has product warranty, or provide retirement / replacement services, you can make the best of those resources.

How to Clean Absorbent Coasters?
How to clean the absorbent coasters if they get dirty?
To the general daily cleaning, you can use water to wash directly, and dry it naturally after cleaning. If it has stains on it, you can use teeth brush to clean it gently. If it has deep color drinks stains (Ex. Coffee, tea) will be more difficult to remove, but the function will not be affected.
The Principle of Absorbent Coasters?
Why can absorbent coasters absorb water? In fact, it’s not true! Absorbent coasters cannot actually absorb water! But water can quickly and effectively penetrate the absorbent coaster, so it looks like the absorbent coaster can absorb water.
The principle of absorbent coasters, to put it bluntly, is using capillary phenomenon to achieve the effect that water droplets will quickly disappear on the absorbent coaster. Absorbent coasters are made by high temperature stamping of ceramics. Therefore, the surface has many small capillary holes, making the water droplets can quickly penetrate downward.
What does the Number on the Cup Lid Mean?
Do you ever notice the number on the plastic cup lid when you buy coffee and take hot drinks? The number is surrounded by the triangle which is made by arrows. Do you know what it is? Actually, this mark is Resin identification code developed by the United States Plastic Industry Association in 1988 for identifying the plastic resin out.
Do not underestimate these small numbers which is hidden secrets inside it!

Depends on what plastic
The most common beverage containers in our life are made by plastic 1, 5 and 6 (see the table above). Among them, No.1 plastic PET because of light weight, good toughness, enduring heating 60 ~ 80 ° C, it is suitable for cold drinks containers or bottles. No.5 plastic PP is acid and alkali-resistance, and its high temperature tolerance is also high (100 ~ 140 ° C). That is why it the most appropriate material for making hot drink cup lid. The chemical stability of No.6 plastic PS is poor, and because of its low heat range (70 ~ 90 ° C), if it heats over 90 ° C, it might release carcinogenic substances. Yet, when businessmen select the container package, the biggest consideration for most of them is the cost. The cost of the safest No.5 plastic products is the most expensive. Therefore, many businessmen often choose to use No.6 plastic products.
As a smart consumer, we should learn to identify the resin identification code for self-protection. In addition, before drinking hot drinks, we had better take off the cup lid!
The Comparison of Lid Materials
Nowadays, many accidents made us realize the seriousness of the food safety problem and environmental awareness. Many people begin to prepare their own reusable cup when they buy coffee. In addition, consumers who bring a reusable cup when buying a beverage can get a discount, which is killing two birds with one stone.
Besides thermos bottles, and glass cups, mug or other ceramic containers are good choices of reusable cup materials. However, except for thermos bottle usually has its own cup lid, the rest of reusable cups can be match with any cup cover.
Below, let′s compare some the common reusable cup covers which made by different materials.
According to personal needs and preferences, you can select the appropriate reusable cup lid.
Environmental Action Let's go!!!
How Excellent the Heat Resistance of Silicone Cup Cover Is?
