The conversion rate of the general charging treasure is generally 80-85%, and the conversion rate of more than 90% is rarely achievedTreasure. When the charging bank is used to charge the digital device, the ups and downs will be converted, resulting in loss, resulting in the actual use capacity of the charging bank is less than the nominal cell capacity.
The conversion rate of most charging treasure is between 60% and 80%, the same is a 10000mAh charging treasure, some can charge 8000mAh, some can only charge 6000mAh, this gap is not small. Here, I will take stock of several charging banks with high conversion rates for your reference.
And this loss is inevitable. At present, the conversion rate of the better charging treasure on the market is generally inAbout 85%.
The conversion rate of 60% is normal. The conversion rate of the power bank refers to the ratio of the maximum power output to the energy absorbed. In general, the conversion rate of charging treasure is between 50% and 70%, so the conversion rate of 60% is within the normal range. However, the conversion rate of different charging banks may be different, so it is recommended to carefully compare different products when purchasing charging banks, and choose a charging bank with a high conversion rate and suitable for yourself.
The highest. The conversion rate of the charging bank is 80 to 85 percent, and few achieve a conversion rate of more than 90 percentTherefore, even if the charging treasure is not full, the conversion rate will reach the highest.
The energy conversion rate of the charging bank is usually about 65%, that is to say, the available capacity of the 10000mAh charging bank is about 6500mAh, and for the current mainstream smart phones, their battery capacity is more than 3500-5000mAh. Therefore, a 10000mAh charging bank can at least provide a complete charge for a smartphone, and if a charging bank with a larger capacity is selected, the number of available charges will be more.
1, 10,000 mah charging bank can charge about 38 watt-hours of electricity. In detail, the electrical energy of the charging bank is generally expressed in "watt-hours" (Wh), which represents the total amount of electrical energy. The "milliampere-hour" (mAh) is the product of current and time, indicating the amount of power a battery can provide. To convert milliampere-hours to watt-hours, we need to know the voltage (V). In most power banks and mobile devices, the standard voltage is 7V.
2, 10,000 MA chargingThe ratio between the actual output power and the total power. For example, after a 10000mAh 7V charging treasure is fully charged, the total power (power = capacity * nominal voltage) should be 37wh, assuming that it can charge a 5v 2000mAh mobile phone 3 times, then the actual output power of this charging treasure should be 30wh, that is, the conversion rate =30/37 is about 81%.
2, the difference between the two is due to the conversion of the battery capacity of the charging treasure itself to the mobile phone battery capacity, through the charging treasure booster circuit, the internal resistance of the mobile phone charging line, the contact resistance of the charging line connector at both ends, and the mobile phone itselfThe loss of the power management circuit, the internal resistance of the cell, etc., will be about 30% of the loss. According to your description, the total conversion rate of this charging bank is: 6600mah divided by 10400mah is about 63%, which belongs to the normal range.
3, the conversion rate of the charging treasure is mostly about 70%, the so-called conversion rate is in the charging process will have a loss according to the conversion rate of 70%, that is, the actual capacity of the 10,000 MA charging treasure is about 7000, and then divided by the capacity of your mobile phone battery is about the number of charging. My Sino 10000 mah power bank for my appleIf the phone is charged 4-5 times, of course, this is only an estimate, I generally charge less than that many times while playing.
4, we usually say that the capacity of mobile power refers to the capacity of the battery cell. In the process of charging the mobile phone with the mobile power supply, the circuit board of the mobile power supply itself will lose power, the adapter is also consuming power, and the mobile phone itself is also consuming power! The conversion rate of the mobile power supply is usually said to be (actual discharge capacity * average discharge voltage)/(actual cell capacity * cell voltage).
5, if the charging treasure does not mark the conversion rate is to buy a fake. General mobile power supplyWill mark its charging capacity, but the power in the use of the process will produce losses, we will actually charge to the mobile phone in the power is called the rated capacity of mobile power, with this value divided by the mobile power identification capacity is the conversion rate of mobile power. Generally speaking, the conversion rate of mobile power on the market now is about 85 percent.
6, cell capacity × 3700mV). Lead dust belt may affect the conversion efficiency of the power bank. In the case of no false target, the output voltage is the biggest factor affecting the conversion rate. Conversion rate refers to the conversion of electrical energy, where electrical energy is equal to the capacity of the batteryQuantity multiplied by the operating voltage of the battery. According to the law of conservation of energy, electrical energy is constant. Therefore, when the voltage is reduced, in order to maintain the same electrical energy output, the output capacity will be increased accordingly.
1, South Carolina magnetic wireless charging treasure POW3. Since its launch, the sales volume of Nank magnetic wireless charging treasure POW3 has been the first. In the charging process, the actual conversion efficiency when the 7V voltage of the internal battery cell is increased to 5V voltage suitable for equipment use is the highest.It has become the most popular charging treasure brand with the highest conversion rate.
2, Nank South Carolina magnetic wireless charging treasure POW3 Nank South Carolina magnetic wireless charging treasure POW3 since its launch, sales have been soaring, widely praised, become one of the most popular magnetic wireless charging treasure brands.
3, Rome Shi this brand of charging treasure price is 99 yuan, cell capacity is 20000mAh, the advantage is large capacity and high conversion, the measured conversion rate reached 979%. And can smart match mobile phones and tablets, strong compatibility. Using the power source charging technologyTo enhance the charging speed. And digital high composite security technology, making the charging process more convenient and safe.
4, the comprehensive performance of the above charging treasure in the actual test has reached the industry's excellent level, the conversion rate is more than 90%, the quality of the components used are also guaranteed, the price is relatively reasonable, and it is worth buying. The purchase of a charging bank must start from its own charging needs and start from the battery capacity of its own mobile phone. The charging demand is relatively large, buy a 20000mAh, the charging demand is relatively small, buy a 10000mAh.
