Most of the reasons in the habit of use will make mini fans easily drain their batteries or damage the circuit after only a short period of use. Therefore, housewives should pay attention to some standard usage methods that will help bring optimal efficiency.
Use a standard charger
Most mini fans currently only receive input current at 5V-1A or 5V-2A, equivalent to power from 5W to 10W. Using the correct standard charger and charging the battery at the right time will help the fan operate stably. Checking the information printed on the fan body is the first step to choose a suitable charging accessory.
Avoid both charging and using
Both charging and continuously using a mini electric fan can make the battery break down quickly, and at the same time pose a risk of unsafety for users.
When the fan is running, the engine radiates heat while the battery also generates heat during charging, causing the device temperature to rise. This prolonged situation can reduce the battery life and the number of effective charging times. You should draw the charger and let the device stop charging before switching to using the battery.
Do not use up the battery
The habit of using a fan to the point of running out of battery will cause the lithium battery to degrade quickly, reducing the ability to store electricity. When you see the fan running weakly or the battery light turn red, you should plug it in and charge it in time.
Store the battery when not used for a long time
When the cold season comes, the preservation of mini fan batteries needs to be emphasized. Do not let the battery drain completely because it can damage the battery and make it difficult to recharge when used in the next season. It is best to keep the battery at about 50% before storing and recharge every 2-3 months to maintain product life.
