Power Bank

Can you take the power bank on the plane? What are the precautions to be taken?

The mobile power supply is a portable charger that integrates power supply and charging functions. The reason why the mobile power supply is called a mobile power supply, so the name suggests, is that its design is light, compact, and easy to carry. Usually, the way everyone uses it is to directly connect the device that needs to be charged with a USB data cable. The mobile power supply can charge the equipment you need and can charge mobile phones and other digital devices anytime, anywhere or standby power supply. Let me give you a little knowledge about the power bank in popular science!

Can the power bank be taken on the plane?

According to regulations, the following points should be noted when carrying power banks on airplanes:

  1. It is strictly forbidden to carry power banks in checked baggage.
  2. It is strictly forbidden to carry power banks with rated energy exceeding 160Wh (watt-hours); carrying power banks with rated energy exceeding 100Wh but not exceeding 160Wh must be approved by the airline and must not exceed two.
  3. It is strictly forbidden to carry power banks with unclear marking.
  4. It is strictly forbidden to use the power bank during the flight.
  5. It is strictly forbidden to carry the power bank for non-personal use.

Among these 5 items, 1, 3, 4, and 5 are easy to understand, and the Wh of item 2 is somewhat different from the mAh we often say. In fact, we just need to convert it. At present, most of the power banks on the market have a capacity of 3000 to 15000mAh. The “capacity” of some power banks is 20000mAh, and most of the power banks have a marked voltage of 3-4V. According to the formula of the rated energy value, when the voltage of a 20000mAh power bank is 4V, the rated energy value is 20000mAh×4V=80Wh, which is less than 160Wh. Therefore, the voltage and capacity of the battery are generally marked on the power bank. You only need to check it yourself and simply calculate it to know if it meets the regulations.

What are the precautions for power banks ?

1. The output voltage range of the mobile power supply. Although some devices have a USB interface, you also need to use a mobile power supply for power supply. However, you should pay attention to the input voltage range of your device. The voltage output range of a common mobile power supply is 5.3 -0.5v. If the input voltage range required by your device is not within the range of the mobile power supply, then it is recommended that you do not use the mobile power supply to power your device to ensure the service life of your mobile power supply.

2. The USB connector must match, because the devices corresponding to various USB data cables are different. Therefore, in order to use the mobile power supply to power your device normally, please use the matching USB data interface.

3. The storage environment of the mobile power supply. All kinds of electrical appliances need to be placed in a dry environment with low air humidity. An environment with high humidity is not good for the storage of all kinds of electrical appliances. Therefore, for the use of your mobile power supply Life, please try to put the mobile power in a dry environment.

4. Use your power bank frequently, charge and discharge the power bank once a month, and use it frequently. It can maximize the service life of the mobile power supply.

5. Anti-fall and anti-vibration. The mobile power supply is actually a fragile component, and the internal components cannot withstand beatings. Especially to prevent accidental landing during use. Do not throw, knock or shake the power bank. Crude treatment of the mobile power supply will destroy the internal circuit board.

6. Anti-cold and anti-heat. Do not place the mobile power supply in a place where the temperature is too high. High temperature will shorten the life of electronic devices, destroy mobile power supplies, and deform or melt some plastic parts. Do not store the mobile power supply in a cold place. When the mobile power supply is working in a cold environment, when the internal temperature rises, moisture will form in the mobile power supply and damage the circuit board.

7. Anti-potent chemicals. Do not use harsh chemicals, cleaning agents or strong detergents to clean the mobile power supply. To remove the stains on the external appearance of the mobile power supply, wipe with a small amount of anhydrous alcohol with cotton.

8. Now many people on the Internet have such questions. Will the use of mobile power damage your mobile phones, tablets, cameras and other digital products? This, please rest assured. The mobile power supply is just for the convenience of equipment for powering various digital products. As long as you buy a mobile power supply produced by a regular manufacturer, there is basically no damage to all kinds of handheld devices. It’s hard to say for the mobile power bank.

Is it necessary to buy a power bank ?

Power bank has gradually become a necessary tool for people’s life and work.

Mobile power is not only defined as a consumer electronic product in the world, but more importantly, it is defined as a daily utility product for life and work. Since the mobile power source realizes the portable application of electric energy, it has a deeper and broader influence than the usual definition of daily tool products (pens, knives, flashlights, dictionaries, etc.). Especially when mobile digital devices (mobile phones, pda, mp4.dvd, laptops, etc. and usb-b portable devices) are becoming more and more important in people’s daily life and work, mobile power is also increasingly prominent as a life and The meaning of an important tool for work. We can define it as an electronic tool, which is a strong backing for the use of various mobile digital devices; we can define it as a household tool, which can completely replace all battery products (5v or 7v) that may be needed in home life Disposable batteries or rechargeable batteries, etc.). At the same time, it has a large capacity, easy to use, low cost of shared use, and environmental protection. Especially as the usb-b portable device enters life, its application will be more extensive, such as the application of supporting usb lights Instead of dangerous and faint candles, it is equipped with a usb eye massager, you can conveniently lie on the sofa and enjoy it. Home medical equipment with a usb connector does not need to consider the location of the plug and the winding power cord. . Wait; we can also define it as work tools, learning tools, travel tools, and so on.
