What is the wireless charging frequency in Europe (German wireless charger)

What do 50Hz and 60Hz stand for?

The 50/60HZ above the charger represents the AC frequency that the charger supports input. The frequency of alternating current used in daily life is generally 50 Hertz or 60 Hertz, while the frequency of alternating current involved in radio technology is generally larger, reaching the metric of kilohertz (KHz) or even millions of Hertz (MHz). The alternating current frequency of the power system in different countries is different, usually 50 or 60HZ.

/60Hz refers to the frequency range of the socket AC power supply, which is generally 50Hz, can also be used for 60Hz AC; 0.1A and 0.3A are the sizes of the charging current. At the same time, the charging voltage is the same, 0.3A charging speed is faster, more heat when the battery is charged (more hot), if the original charger is 0.1A, try not to use 0.3A, with the phone itself harmless, most affect the battery life.

-240V refers to the voltage range; AC means the use of alternating current; 50-60Hz refers to the alternating current positive and negative conversion frequency, our country is 50HZ is the conversion of positive and negative 50 times per second; 0.5A refers to the operating current. This chargeThe power of the appliance is about 220V*0.5A=110VA=110W, and it is close to one degree of electricity after 9 hours of charging. What is the output voltage after the voltage change, can not be seen from this string of parameters.

How many Wi-Fi lines are there in Europe?

The distinction between the first, second and third lines of wireless in Europe is mainly based on the quality of service provided, coverage, capacity and reliability. First-line services typically have the highest quality, widest coverage, and largest capacity, while third-line services may be limited in these areas.

European radio second line refers to the medium frequency of European radio stations, its frequency range is 430MHz to 440MHz, mainly used for medium distance communication, such as domestic long-distance communication, air traffic control, aviation, etc. The European wireless third line refers to the lowest frequency of the European radio station, its frequency range is 144MHz to 146MHz, mainly used for short-distance communication, such as car walkie-talkies, short-distance aviation communications, etc.

There is a difference between 3G and 4G networks in Europe. 3G and 4G belong to two eras of the network, 4G is the evolution of 3G or improved version, no matter which country andRegions, as long as there are classifications, there are differences. 3G: 3G is the third generation of mobile communication technology, which refers to the cellular mobile communication technology that supports high-speed data transmission. 3G services can transmit both voice and data information at a rate of several hundred kbps or more.

There are wifi wireless networks everywhere in Europe, such as fast food restaurants, hotels, most Europeans use the wireless network at home, they will go to the network company to apply for the network, the price of 30 to 50 euros per month.

If you have a laptop with you, keep in mind that hotels in Europe do not usually provide Internet access, but you can connect via the hotel's WiFi. When booking a hotel, you can check out the services offered by the hotel on online platforms such as Bingke.com in order to know in advance whether the hotel offers the required services such as WiFi.

For friends traveling in Europe, buying a 7-day data plan can usually meet your Internet access needs. If you have a laptop with you, keep in mind that hotels in Europe do not usually provide Internet access, but you can connect via the hotel's WiFi. When booking a hotel, you canCharging speed increased by 33%< /strong> Europe wireless charging frequency , 0%~80% charging only 45 minutes, greatly improving the use experience.

Align the charging port on the back of the watch and fit the metal contacts on the charging base, adjusting the fit until the charging indication appears on the watch screen. It is recommended to hold the charging base to the watch. After placing it, check the charging icon on the watch dial. If the charging icon is displayed, it indicates that the watch is being charged. If the charging icon does not appear, you need to adjust the position slightly to ensure the fit until the charging icon appears.

can be placed on the magnetic charger overnight charging, because the charging input of the iwatch is not high, maintain about 0.01a after full, the battery will stop charging, standby, if you open the bedside clock mode, it will not necessarily charge 100% for a night.

Supports wireless charging, Apple Watch uses sapphire screen, two screen sizes. Support phone, voice back text message, car connection, weather, flight information, map navigation, play music, heartbeat measurement, step counting and other dozens of functions, is a health and sports tracking device. Apple WatchUsing a MagSafe-style wireless charger. It magnetically attaches to the back of the Apple Watch and is then charged inductive.

The interface is different and cannot be used directly. The Apple Watch has the ability to charge wirelessly, making it the first Apple mobile device with wireless charging. The Apple Watch uses a MagSafe-style wireless charger. It magnetically attaches to the back of the Apple Watch and is then charged inductive.

Apple WatchThe Apple Watch uses wireless charging and comes with a power cord and power adapter. After removing the tape from the outer layer of the power cord, use the white side to touch the back of the Apple Watch for charging. Put the circular connector of the charging cable near the back of the Apple Watch to attach it for charging.

Does wireless charging damage the mobile phone battery

1, no, wireless charging will not reduce the performance of the battery faster. Battery manufacturer pairThe design of the amount of energy stored in the battery determines the amount of electricity we can use. The manufacturer sets a fixed upper cut-off voltage and a lower cut-off voltage, and electrically cycles between the two voltage ranges, so long as we choose the right voltage range, we can cycle the battery thousands of times.

2, wireless charging will not affect the battery. Regardless of whether you use a wireless charger or a wired charger, even if you leave your hand on a wireless charging pad for a long time, or leave it on overnight, it is impossible to exceed the manufacturer's energy limit, and you cannot discharge power outside the manufacturer's lower cut-off limit.

3, wireless charging in addition to the charge can not be directly supplied to the hardware, other aspects have no impact. You said that the injured battery is wireless charging while playing will be far more than the wired battery, because the wired power supply does not use the battery, and the wireless is charging while discharging. Long-term use of radio charging will not affect the phone battery.

What does 50/60HZ mean on the charger

1. Support AC power at 50hz and 60hz. 50/60Hz indicates that the device supports 50hz and 60Hzhz AC, such as China's AC is 50hz, Japan is 60hz, this unit indicates the frequency, and power independent, 50/60HZ represents the charger support input AC frequency.

2, /60Hz refers to the frequency range of the socket AC power supply, generally 50Hz, can also be used for 60Hz AC; 0.1A and 0.3A are the sizes of the charging current. At the same time, the charging voltage is the same, 0.3A charging speed is faster, the battery is charging more heat (more hot), if the original charger is 0.1A, try not to use 0.3AThe use of the phone itself is harmless, at most affect the battery life.

3, input100-240: Input AC 100V~240V China's mains power is 220v, Japan and Europe have 110V voltage, which means that your adapter can be used directly in most countries in the world.

How often do I make wireless chargers?

At present, the Qi standard formulated by the Wireless Charging Alliance (WPC) stipulates that the charging frequency is generally about 100kHz, and it is recommendedTake a look at this standard, it is the current more mainstream standard in wireless charging.

w. At present, domestic mobile phones have supported 50W wireless charging, 50W is also the upper limit of the provisional wireless charging standard, but even so the frequency of wireless charger is still not as good as the traditional charger, Samsung launched 15W wireless charger at this time, it is confusing.

To effectively reduce the adverse effects of electromagnetic radiation on health. For mobile phones: under normal circumstances, it will not harm the mobile phone, and the working frequency of wireless charging is now below 1M, so it will not affect the signal of the mobile phone.Wireless charging has no effect on mobile phone battery life, and wired charging is basically the same, but the rate is lower, but the wireless charger conversion rate is still high, more energy saving.

Wireless charger operating frequency, according to QI standard is 110-205kHz; The frequency of mobile phone communication is in the range of 0.8GHz to 2GHz (the communication system will vary, 1GHz=10^9Hz). The different frequencies make the mechanism of their impact on the human body is different.

Wireless charging, and even remote sensing charging. Its principle is electromagnetic sensationShould, usually used in small power applications, do not require electrode contact points. There are induction coils in the small column and electricity, there are induction coils in the electric toothbrush insertion part, and there are plastic insulation outside, there is no electrical contact, and the induction obtains electricity to charge the battery and drive the small motor.
