Is 3500 mAh enough, and can 3000 mAh be used in a dormitory

Now mobile phones are generally about 4000, and the battery life of 3500 mAh mobile phones should be very average, so it is recommended to choose a mobile phone with better battery life.

3000 mAhPower bankIt can be used in the dormitory. If your power bank is only 3000 mAh, then there is no problem at all to use it in the dormitory.

3000 mAh, although you see it is relatively large, but its charging power is only about 20 watts, which is far from the 800 watts limit in the dormitory.

And you belong to a small power bank, for the mobile phone can only be charged once, so you can only use it in the dormitory, if you take it out, and can not provide a long-term standby function for the mobile phone.

We know that the general school dormitory attaches great importance to the daily safety of students, and how many watts of electrical appliances can be used in the dormitory are generally controlled at 500w, which is a basic protection for students' daily electricity safety.

The use of electrical appliances, any electrical appliances should be carefully mastered before use, and the correct use should ensure safety. Then it is to pay attention to the maintenance of daily wires, let's take a look at the following finches.

Generally, the power limit in university dormitories is 500W, which means that all electrical appliances in a dormitory cannot be more than 500W (of course, this does not include dormitory lighting and air conditioning).

Matters relating to the use of electrical appliances.

1) When purchasing household appliances, you should carefully check whether the technical parameters of the product manual (such as frequency, voltage, etc.) meet the local electricity requirements. It is necessary to know how much power is consumed and whether the existing power supply capacity of the family meets the requirements, especially whether the wiring capacity, plugs, sockets, insurance, and electricity meters meet the requirements.

2) When buying household appliances, you should also understand their insulation performance: it is general insulation, reinforced insulation and double insulation. If it is grounded for leakage protection, the grounding wire.

Absolutely necessary. Even for reinforced or double-insulated electrical equipment, it is used for protective grounding.

Or there are also benefits to protecting the zero.

3) Household appliances with electric motors (e.g. electric fans.

etc.), you should also know the level of heat resistance, whether it runs continuously for a long time. Pay attention to the heat dissipation conditions of household appliances.

milliampsThe equivalent of how many watts in the calendar is to know the resistance or electric model blue pressure to calculate.

Because milliamps describe the magnitude of electric current, and watts are units that describe the power of electrical appliances. A conversion is required between the two.

So you need voltage or resistance to find the watts, 1 watt = 1 volt 1 ampere, 1 ampere = 1000 milliamps.

Summary. Hello, the difference between 4800 mAh and 3500 mAh is mainly the difference in capacity.

The 4800 mAh battery is 800 mAh larger than the 3500 mAh battery, and in terms of battery life, the 4800 mAh battery is also better than the 3500 mAh battery, and the use time is longer.

What is the difference between 4800 mAh and 3500 mAh.

Hello, your question I have seen that the trip has arrived, is in the Xiangshan Li answer, typing takes a little time, please wait patiently for a while, you can also describe other questions!

Hello, the difference between 4800 mAh and 3500 mAh is mainly the difference in capacity. The 4800 mAh battery is 800 mAh larger than the 3500 mAh Nian Yedan battery, and the 4800 mAh battery is also better than the 3500 mAh battery, and the use time is longer.

3500 mAh and 20 watts are the parameters of the battery, and the power and power of the battery are shown in this table, respectively, and the two cannot be directly compared. To determine the relationship between the two, you need to know the formula between electricity and power (voltage and current): power = electricity voltage.

Therefore, if the voltage has been determined, the amount of electricity can be judged by the amount of power. Generally speaking, 20 watts of power is more than 3500 milliamps, so when using electronic devices, you need to pay more attention to the amount of power. Of course, when choosing a power supply, you also need to pay attention to whether the amount of power required by the device and the amount of power required are appropriate, too large or too small may damage the device or cause it to be unusable.

If there is a problem with the battery, such as reduced capacity, shortened service life, etc., you can replace it with a new battery of the same specification, and pay attention to the correct connection of the positive and negative electrodes. If the equipment fails, you can find a professional to repair it or replace the accessories. When using electronic equipment, it is necessary to pay attention to the sufficient charging time and correct use of the battery, do not disassemble or repair the electronic equipment without authorization, keep the battery surface dry, prevent soaking or breaking, etc., so as to prolong the life of the equipment.

Hello, dear very filial piety, happy to answer for you, milliampere is 300, you can use 3000 milliampere! This doesn't matter, it only has to do with its merit and caution rate; It indicates that under specific discharge conditions (usually , the rated capacity of the battery takes 3000mAh as an example, in the case of constant current discharge at 300mAh; Can be discharged for 10 hours (300mA x 10h = 3000mAh) in a nutshell, if the discharge speed is high; The effect will be reduced proportionally compared to 3000mAh.

Logically yes. Normal or non-original accessories are dangerous to the hardware safety of the hand-made machine. During the design process and later testing process, all hardware and software will be optimized, including heat dissipation, battery capacity, processor scheduling, wit, etc.

If you change the accessories later, such as a non-original screen or a non-original battery, it is likely that the quality of the screen and the characteristics of the battery itself will affect the function of the phone.
