I believe that many friends will encounter this situation. No matter if they buy a new portable power station or a mobile phone, etc., they are not fully charged. Do you suspect that the purchased one is second-hand or there is a problem with the power supply? In fact, this does not determine the old and new standards of the portable power station. The newly purchased portable power station or mobile phone is generally not fully charged before leaving the factory. Next, the editor will explain to you why the portable power station is not fully charged!

Why is the new power supply not fully charged?

Generally, advanced portable power stations use lithium-ion batteries. Although nine procedures will be tested before leaving the factory to ensure that the highest quality products will be delivered to electric fans. However, it is stipulated in the transportation industry that in order to ensure the safety of transportation, the experimental results of multiple technical centers show that when the state of charge drops to 30%, most of the tested battery cells have no heat conduction diffusion phenomenon, which can effectively reduce the risk of transportation and Dangerous accidents occur, so for safety reasons, the portable power station that appears in everyone's hands is not fully charged.

The new power supply is not fully charged, should it be fully charged and then recharged?

The portable power station will do a complete charge and discharge test before leaving the factory, and the lithium battery has no memory effect, and there is also a BMS (battery management system) that can fully protect and balance the safety of the lithium battery pack, so the newly bought portable power station The station can be recharged whether it is fully charged or recharged after it is fully charged.

But although the impact is not great, in order to make the portable power station last longer, I still suggest that it is better to charge it shallowly and discharge it lightly. Such as shallow charging: usually charge to 90%; shallow discharge: when the remaining 20% ​​of the power is used, 30% can be charged, and there is no need to wait until the power is used up to recharge or fully recharge.

Store the power supply for a long time and need to charge it regularly?

Portable power station products all have a certain amount of self-consumption, and the better the quality, the smaller the self-consumption. Of course, this is also related to the capacity of the power supply. For example, the portable power station has a power of up to 1000W, which has a large capacity and very low power consumption.

However, it is recommended that if you do not use it for a long time, you should avoid leaving the power supply in a state of power loss for a long time, and charge the battery to a half-charged state (30%-60%), and at the same time, it is best to charge and discharge once in about 3 months and try again.
