The battery generators have only been available for two or three years, but they have provided an irresistible outdoor power solution for outdoor power consumption in daily life and outdoor work. Whether it is aerial photography, surveying and mapping, mobile medical treatment, self-driving travel, picnic camping, entertainment life, all walks of life are empowered by battery generators to enjoy a safer, more portable, efficient and environmentally friendly electricity experience.
How does the power supply work when charging and using?
This problem requires two situations:
If the output power is less than the input power, there is no need to draw power from the battery, then the device can be powered directly and the battery can be supplemented with excess power.
If the output power is greater than the input power, you need to take power from the battery, the battery is not charged, and it needs to consume power, and the more you charge, the less you will be.
Does charging while using affect the life of the power supply?
If the output power is greater than the input power, it is necessary to draw power from the battery. This situation is equivalent to using battery generators directly, which will naturally increase the number of cycles of the battery, which will affect the lifespan.
Of course, what really affects the life of the power supply is not using while charging, but temperature. The ideal charging temperature for battery generators is 0-40°C. Charging under high temperature conditions will affect the life of the power supply.
In addition, the power supply will generate heat when charging, and we will also generate heat when using electrical appliances. If the temperature generated by both working at the same time is high, it is recommended not to use it while charging.
Will the number of cycles be counted while charging and using?
Generally, the number of cycles of charging and discharging lithium batteries is about 500 times, and the same is true for battery generators. A complete charge and discharge (full use up), for a cycle! So you don't have to worry that charging and using will increase the number of cycles of the power supply.
Should the newly purchased power supply be empty and recharged?
In fact, lithium batteries do not have a "memory effect", so there is no new battery generators that you buy. You must empty the battery and then fill it all at once. On the contrary, the lithium battery is afraid of deep charging and deep discharging, and it will affect the life of the power supply every time the power supply is used up before charging.
Usually it is recommended to charge to 90%, preferably shallow charging and shallow discharging: for example, if there is 20% left, 30% can be charged.
