How long does it take to charge the rechargeable fan's 18650 lithium battery to full capacity?

..........Nowadays, batteries are generally 2500 mAh. It is best to use a standard 1A charger. Generally, an 18650 battery can be fully charged in 3-4 hours. ..........If you use a high current charger, the charging will be very hot, which will damage the battery.......And the high current charging can only charge up to about 80%, then it will be charged to about 80%. If you continue to charge with a low current, the full charge time is actually about the same... For the previous 1500mAh small capacity battery, about half. the time was enough...

...As for those batteries worth more than 3,000, most of them are just gimmicks...

Newly purchased USB rechargeable electric fan, 5V power supply How long does it take to charge for the first time before it can be used without charging?

In order to prolongTo extend the life of the electric fan, it is generally necessary to fully recharge it. charge the battery before using it.

Take a look and see if there is battery capacity for the electric fan. Suppose your battery capacity is 1500 mAh and the charger charging current is 500 mA, the charging time will be at least 3 hours. Now the batteries are all lithium batteries. They will not charge at a constant current and can take 3 1/2 hours to fully charge.
