do not charger your phone until energy runs out

Many people think that the phone should be recharged when its energy runs out, which is good for the battery and saves power. In fact, the opposite is true. When the mobile phone battery is running out, charging with power bank will cause the charging current to rise, generating more unnecessary heat and waisting power.

Because when the lithium battery of the charged device is low, it is charged by the power bank, and the power bank will discharge under the constant current output with large power consumption, which is a kind of damage to the power bank and the mobile phone, so When we go out, as long as the mobile phone and other devices are idle and the power is not fully charged, it is better to use the power bank to charge the mobile phone for a small current, so as to reduce the waste of the power in the large current output state. .
