How to buy a power bank power bank ? What are the common brands of power banks? What is generally u

Generally, it is divided into domestic brands and imported brands, domestic brands such as Yubo, Dianxiaoer, Scud, Pinsheng, etc., more small brand copycats can not be used, imported brands such as Energizer, Maxell, Sony, Philips are rich experience in battery production. Mobile power ** from fifty yuan to five or six hundred yuan, the appearance looks similar, but in fact, there is a big difference inside, some are ** old battery reactivation, such a battery is very unstable, easy**. Therefore, when choosing a mobile power supply, you must look at the battery cell and whether it is the original configuration.

Attention is also paid to the protection function. A high-quality power bank should have protection functions such as load self-test, overload protection, short circuit protection, and insulation protection. In general, it is recommended to use Maxell with a high cost performance.

Now there are a lot of domestic cottage mobile power supplies, some of which are of inferior quality, and the key to choosing is to pay attention to your needs. If you're just on your way to and from work, recharge your phone. That's basically 5000 mAh is enough (the power supply at this level is still relatively small), if you want to go out for fun or a business trip.

Then it is recommended to buy a power supply of more than 10,000 mAh, which can basically charge the Apple 4S 4-5 times. As for the brand, you can go to Zhongguancun, the Pacific Ocean, these ** on the mobile power channel to check it, basically these brands of things are OK, that is, when buying, you should buy a good point in regular** or Tmall, Jingdong, these places.

Choose the brand, I use the electric Xiaoer, I bought it last year, and it is very convenient to use.

First: look at the brand.

There are many power banks of big brands, such as Scud SCUD, Patriot AIGO, Philips, Sanyo Alepu, etc.

Second: look at the battery cell.

Most of the cells are composed of pouch lithium batteries and 18650.

Pouch lithium battery, also known as polymer cell, is a paste-like battery that can be manufactured into various shapes, so it is called pouch in the industry.

18650, liquid lithium battery, 18 and 65 indicate the size of the cell, 0 indicates that it is cylindrical.

Third: look at the protective board.

The protection board mainly has the function of automatic adjustment of charging and discharge, automatic shutdown of charging at full point, and can also improve the conversion rate and reduce the influence of resistance on charging.

Fourth: the appearance of the power bank.

After all, if you want to extend the life of the power bank, it is not enough to have excellent quality, but also to have good habits.

First: the frequency of use of the power bank should not be too high, the electricity should not be too full, and of course, there should not be no electricity at all.

Second; In the case of infrequent use, the power bank can be kept at about 80% of the power, and it cannot be placed for too long without hidden power or less.

Third: the power bank can not be placed in a place where the temperature is too high or too low, and the general power bank will be very clear in the manual.

the fifth section of the stove; Do not knock or throw the mobile power supply roughly, which will easily cause the solder joints to fall off.

Sixth; Do not plug both ends of the data cable into the power bank, which can easily lead to a short circuit.

Seventh, sell cautiously; Do not put metal objects together and avoid wet places to avoid short circuits.

Eighth; Try to choose a good quality data cable. Charging will be safer and more efficient.

There is no difference, it's the same thing.

Portable chargers for charging consumer electronics such as handheld mobile devices (e.g., wireless**, laptops), especially when there is no external power supply**.

Its main components include: a battery for energy storage, a circuit to stabilize the output voltage (DC-DC converter), and most power banks have a charger that is used as a built-in battery to charge.

See if you want an ordinary power bank, a back clip power bank, a wireless power bank?

Ordinary power bank is available, such as Romas, Xiaomi, Pinsheng, Yubo, etc., especially Romas** with affordable capacity.

If it's an alternative power bank like a back clip power bank or a wireless power bank, you can take a look at Uobor's, they are more awesome at engaging in this kind of powerhouse.

It is recommended to sell Huawei, Xiaomi and other regular manufacturers Today I saw the WALL-E wireless charger on JD.com I asked the customer service which manufacturer made it He actually said sorry He didn't know ......

This one is simple.

Generally speaking, the domestic sales volume is large, and the reputable mobile power supply is ***. Such as domestic brands such as Scud, Pinsheng, Lijie, Yubo, and Dianxiao.

Second, the quality of these brands of mobile power is not bad, and it is also specific and cost-effective.

If the economy is relatively rich, you can look at some internationally renowned brands, such as: Sanyo, Philips, Energizer, Panasonic, GP, etc., these brands are of good quality, but they are also correspondingly higher. Hope to adopt.

Pinsheng, Romashi, Huawei Xiaomi.

The blue crane is okay, and it's not bad to use.

Baseus small square bracket wireless fast charging mobile power supply adopts a pull-out mobile phone holder design, which can charge the mobile phone while chasing dramas, and the fixed mobile phone has a good film and television effect, and the convenient charging is fully charged at any time, and the important business is not delayed. 18W high-efficiency charging, as fast as the original charger, compatible with Huawei, Xiaomi and other mobile phones that support the Qi wireless charging protocol, the charging speed is more than twice as fast as ordinary chargers.

These are worth having; Pinsheng, Romashi, Huawei Xiaomi.

Patriot, Pinsheng, there are many brands of power banks, which are basically very easy to use, and they are sold on Jingdong Tmall. You can choose according to your needs. **There are many kinds of money.

Buying a mobile power supply first looks at the power capacity, not the bigger the better, some power supply capacity is very large and there is a suspicion of false standard, to choose according to their actual needs, too small and can not achieve the charging effect, generally 4000-8000 mAh is about the same, of course, if you often travel, long-distance business trips, you can also choose more than 10000.

The second is the battery cell, generally speaking, the polymer battery cell is safer to use than ordinary lithium batteries, of course, it will be more expensive.

In addition to the plastic often used on the market, there are also some aluminum alloy appearances, which will be more durable, not easy to damage, and look more atmospheric and beautiful.

Finally, there are the product details, such as some mobile power banks have a curved design on the side of the fuselage, which has a good sense of touch; Some power supplies have LED emergency light design, as well as humanized designs such as remaining power display and reminder. These details can reflect the quality of the product, and you can rest assured when you buy it.

a.Waste of power bank battery energy (empty with high-capacity batteries) bThe temperature of the power bank becomes higher when it is working; Waste power bank battery energy.

c.The volume of the mobile power bank needs to be increased to cool down the heatDue to the early end of the life of the mobile power supply due to the high temperature work, many manufacturers are weak and dare not indicate the output power or capacity; Only the capacity (or battery capacity) should be indicated; The language is vague.

The problem of commercial mobile power supply also exists, just like a computer hard disk, we calculate 1024, but the manufacturer is calculated according to 1000, and each hard disk will be reduced; The mobile power supply on the market is one of the most conservative labels of the Unios brand, and it can be bought all over the country. According to the above conversion rate, the power supply is marked as 2600mAh, which can probably be charged more than 2 times, and the smart phone can be used about 1 time.

When buying a power bank (mobile power supply), you should look at the following aspects to make a purchase:

Power bank capacity, large capacity is good. However, it is necessary to rule out the situation of false standard of mobile power supply.

The quality of the battery. Like some large power supply manufacturers use polymer batteries or brand-name lithium batteries, such as Sanyo and Samsung. The use of such batteries is longer.

And some small factories only use miscellaneous battery cells for their products. The judgment of the battery cell can only be seen from the inside when the mobile power supply is turned on. And some power banks cannot be turned on or lose their warranty after being turned on.

The temperature at which the power bank is operating. The power bank will definitely heat up when it is charged and discharged, especially when charging. If the power supply is only slightly heated when charging and discharging, the power supply that generates more heat is better than the power supply that generates more heat.

Volume. Smaller size is better.

Weight. It is better to have a larger weight of the power bank. But to rule out some copycats, in order to deceive consumers, an iron block is added inside the power bank to increase the weight. In this case, you also have to turn on the power bank, which can be seen from the inside.

Battery level display. A power bank that uses an LCD screen to display the power level is definitely better than a power bank that only uses a few indicators to indicate the battery.

When buying a power bank, it is best to choose a big brand product with a high reputation.

The first to appear on the market was the concept of a power bank, which began to appear in 2002. And what really made the power bank popular was the rise of smartphones like iPhone, Android and tablets like iPad.

The simple reason is that these digital devices are large consumers of electricity, and the reality of battery technology makes these devices not have a strong battery life. The iPhone is basically charged once a day, and the Android is okay, and the battery can be replaced. In order to solve the problem of inconvenient charging, the mobile power supply comes in handy.

The power bank and power bank are actually a zero-hour power storage device, and the user first connects it to the socket to fully charge. Then when your digital device (such as iPhone or iPad) runs out of power, connect the power bank or power bank to the device, so that the power in the power bank will be transferred to the digital device.

Power bank is actually a more popular name in China, so mobile power supply and power bank are actually the same thing in the civilian field, the same product. Now that the power bank market is very mature, these devices may basically store more than 10,000 mAh of power, which is enough to charge an iPhone more than 3 times.
