What method is used to detect the capacity of the power bank

1. Charge your digital products repeatedly with a power bank, and then flush when you run out of points. For example, the battery capacity of a digital product is: 2000mAh.

A 7800 mAh power bank can theoretically charge your digital products about 3 and a half times (because there will be consumption in energy conversion, so charging 3 times can be regarded as a good product, the general conversion rate ranges from 75% to 85%, depending on the manufacturer's R & D strength, after all, the cost of developing a good board with a high conversion rate will be a lot.

2. If your phone is fully charged twice or three times and it is over, you can calculate that 2000 times 3 equals 6000 mAh, which can be concluded that there are two possibilities.

a. The actual cell capacity of this power bank will not exceed 8000 mAh, and the manufacturer deliberately marks a large capacity in order to make profits.

b. In the case of sufficient batteries, manufacturers do not pay attention to the development of power boards, and only use power boards with 60% conversion rate.

3. Judging criteria: generally more than 72% is acceptable, good brand products will be about 80%, and you have to pay attention to less than 70%. No.

The power conversion rate is not high, and perhaps the components also use substandard products, which then causes safety accidents.

The power of the power bank is all used up, and then start charging the power bank on the socket, calculate how many hours it will take to fully charge, and then see what the input current is (the adapter or charging plug will be marked).The current x time can be converted to mahFor example, if the input current of 1A is charged for 10 hours, it is about 1A*10H=10000mAh

Of course, this is only an approximation, because there will be losses during the charging process. There is also a way to charge the mobile phone after the charging treasure is full, see how many times you can charge the mobile phone, and then convert the approximate capacity of the charging treasure according to the battery capacity of the mobile phone. It's also an approximation, if you want to be accurate, you can disassemble it yourself and take a tool to detect it.

1. Charge the cover code electric treasure.

Capacity judgment method: The power indicator of the power bank indicates the voltage level. Generally, 1 cell.

The standard value of the voltage is full and the discharge can be discharged to. The capacity of a battery cell is generally 2200mAh, and the power bank is generally 3 cells connected in parallel, and the capacity is 6600mAh.

2. Charging identification. A 10,000 mAh mobile power source, charged with a one-ampere charger, takes about 7 to 8 hours to be fully charged, and it takes about four hours to use a two-ampere charger. You can simply understand that one hour is one amp, 10,000 milliamps will be charged for ten hours, and two amps will be charged for 5 hours.

Power bankGenerally, the capacity will be marked on the shell, and of course, there is the following method to check the capacity of the power bank.

Tools Raw materials: charger, power bank

Specific steps:

1. After purchasing the power bank, first observe the label of the power bank, which describes the information of the power bank in detail, such as capacity, model, production date, and rated capacity.

Conversion rates and much more.

2. The newly purchased power bank first confirms that there is no power in the power bank, and then uses the standard suitable cluster to laugh at the device.

Charge your power bank and time the time it takes until the charge is complete.

3. For example, the size of the charging current difference is multiplied by the time taken for charging, 4h, which is equal to about 8000mA.

4. You can also disassemble the machine for testing, after dismantling the machine, you can see the structure of the components inside, the fake and shoddy products will use one or two batteries as a power source, and the others will be replaced by sand or stones to confuse consumers.

Summary. Hello yo dear I'll help you solve this problem The specific solution is as follows: the power bank will generally mark the capacity on the shell, of course, there are other ways to check the capacity of the power bank.

1: After purchasing the power bank, first observe the label of the power bank, which describes the information of the power bank in detail, such as capacity, model, production date, rated capacity, conversion rate and many other information.

2: Confirm that there is no power in the power bank of the newly purchased power bank, then charge your power bank with a standard adapter, and time the time taken until the charging is completed. For example, the magnitude of the charging current is multiplied by the time taken to charge 4h equals about 8000mA.

3: You can also disassemble the machine yourself, after dismantling the machine, you can see the structure of the components inside, the fake and shoddy products will use one or two batteries as a power source, and the others will be replaced by sand or stones to confuse consumers.

Hope it helps

Can you help me see the capacity of this power bank.

Can you bring this power bank on the plane?

This power bank is 12000 mAh pro

The power bank is to see the rated capacity, and the pro-rated capacity refers to the capacity of the motor or electrical appliance indicated on the nameplate that can continue to work for a long time under the rated working conditions. Generally, the transformer refers to the apparent power, the motor refers to the active power, and the phase modulation equipment refers to the apparent power or reactive power, the unit is VA, KVA, MVA. ❤️

Hello, yes, it's okay, dear to you, this power bank is only 12000, which is within the power of this picture

Hello dear <>, I have helped you find the result; To check the capacity of the power bank, you can follow the steps below:1: Check the external logo of the power bank:

Some power banks will indicate their capacity information on the outside. You can check the printing, label, or screen display information on the power bank, which usually shows the capacity of the power bank. Capacity is often expressed in milliampere-hours (mah) or watt-hours (wh).

2: Check the power bank packaging box or manual: If you still have the packaging box or manual of the power bank, you can find information about the capacity of the power bank in this collapsed information.

Check the product specifications or technical parameters section, which may list the capacity of the power bank. 3: Use the display that comes with the power bank:

Some high-end power banks are equipped with built-in displays, and you can view the capacity information of the power bank on the screen by pressing the button or lifting the lid on the power bank. These displays usually show a percentage of battery remaining or a specific value. 4:

Use the relevant mobile app: Some power bank brands may offer a corresponding mobile app where you can connect your power bank to see details such as capacity. Once you open the app, you can usually find the display <> of the power bank's capacity on the interface
