I believe that many friends will encounter this situation. Whether it is a new Portable Power Station or a mobile phone, etc., they are not fully charged. Do you suspect that you bought a second-hand battery or there is a problem with the power supply? In fact, this does not determine whether the Portable Power Station is new or old. Newly purchased Portable Power Stations or mobile phones generally do not leave the factory with a full charge. Below, 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 test 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 happen, so for the sake of safety, 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?
Portable Power Station will do a complete charge and discharge test before leaving the factory, and lithium batteries have no memory effect, and there is also a BMS (battery management system) that can fully protect and balance the safety of lithium battery packs, so the newly bought Portable Power Station The Station can be recharged whether it is fully charged or fully charged.
But even though the impact is not great, in order to make the Portable Power Station last longer, the editor still recommends that it is better to do shallow charging and shallow discharging. 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.
The power supply needs to be charged regularly when it is stored for a long time?
All Portable Power Station products have a certain amount of self-consumption. 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 self-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.
