3.7V-2400mAH lithium battery charger power supply

The output is DC 5.0 V-500 Ma, which is a power supply, not a charger. Do you want to watch fireworks during the Spring Festival?

Let's buy a lithium battery charger ~ ~ ~

The calculation of power is simple: voltage x current.

Dc 5.0 v-500ma, which is 2.5W

I learned physics in junior high school for nothing ~ ~ ~

But at present, there is no good finished lithium battery charger, so the ten-yuan universal battery on the market is not counted, which is too rubbish, but there are many kinds of lithium batteries, so it is difficult to find a good lithium battery charger, which is really bad. Gold makes do with comparators and low-grade goods of 43 1, but none of them really use integrated charging chips. At least I didn't find that anything under 30 is not even garbage. For example, the outdated Samsung charger, Nokia DT 14, DT33, or buy some chips for assembly, 4056, 4057, 1879 or whatever ~ ~ ~

Since you added it, I'll make it clear to you ~ ~ ~

Enter AC 100V-240V 50/130ma, that is to say, you can enter AC100v-240v. For example, when the voltage in the United States and Japan is 1 10V, it can also be used, which can be considered as international common. 50/60HZ is the AC frequency. The national frequency of 1 10V alternating current is generally 60HZ, and 130mA means that the maximum power consumption of alternating current is 130mA.

The output DC is 5.0 V-500mA, that is, the rated output voltage is 5V and the rated output current is 500mA. It can work stably for a long time at 5V and 500 Ma. According to the label, the rated power can be calculated as 2.5W, and the actual maximum output power is far greater than the rated power, with abundant power and high use safety ~ ~

Your so-called charger is actually a power supply. There is a charging circuit in MP5, but everyone is used to calling it "charger", and so is the mobile phone. Many mobile phones are marked with "charger" on the power supply, but they cannot directly charge the battery. This wrong name has become a habit, just know it in your heart. Don't be silly. If the 5V power supply is directly charged into the lithium battery, fireworks may drop ~ ~
