This blog is about the parameters of portable power stations.

1. Storage Capacity:
It determines the number of hours for which the battery can be discharged at a constant current to a defined cutoff voltage.
2. Energy Density:
The energy density is the amount of energy that can be stored.
3. Specific Power:
This parameter is defined as the power capacity per kilogram of battery, in W/kg.
4. Cell Voltage:
The cell voltage is determined by the equilibrium thermodynamic reactions that take place inside the cell.
5. Charge and Discharge Current:
During the discharging process in a battery, electrons flow from the anode to the cathode through the load, to provide the required current and the circuit is completed in the electrolyte.
6. State of Charge:
The state of charge (SoC) defines the amount of stored energy relative to the total energy storage capacity of the battery.
Often referred to as DoD(in %), this parameter expresses the battery capacity that has been discharged relative to the maximum capacity.
8. Cycle Life:
The cycle life determines the number of charge/discharge cycles that the battery can experience before it reaches a predetermined energy capacity or other performance criteria.
9. Self-discharge:
This parameter defines the reduction in energy capacity of the battery under no-load conditions (e.g., open circuit), as a result of internal short-circuits and chemical reactions.
Due to internal losses and material degradation, not all the energy supplied to the battery during charging can be recovered during discharge.
11. Size
The size of the battery is about the power inside.
12. Power Output
Charging speed, Different charging ports may provide different amounts of power.
How many devices do you need to charge?
With multiple ports, simultaneous charging is super-easy.
14. Efficiency
More efficient battery packs will have a lower operating temperature, which wastes less energy, giving it a longer life expectancy.
OCP prevents too much power from going into the battery pack and the power from going out to the connected equipment, protecting the delicate circuitry of both devices.
Like OCP, OVP protects both the battery pack and the connected device by keeping the voltage within recommended safety parameters to avoid damage.
17. Over Discharge/Charge Protection
High-performing batteries should not be overcharged or fully discharged to prolong their life expectancy.
