With the continuous escalation of outdoor activities, during the epidemic period, outdoor activities have gradually become a way for people to relax and vacation, and the problem of outdoor electricity consumption has always troubled everyone. However, as a large-capacity portable power station that can store electricity The emergency portable power station has become one of the essential equipment for people's outdoor activities when playing outdoors. Before purchasing an outdoor energy storage power supply, many people need to know about its power supply duration and what equipment it can carry. Only in this way can we ensure sufficient power supply, so how to calculate the degree of emergency portable power station? Let's take a look at the commonly used calculation formulas for the duration of outdoor energy storage power supplies
1. Partastaremergency portable power station 2000wh is equal to how much electricity
The answer is: 2 degrees of electricity. 2000wh refers to the electrical energy consumed by an electrical appliance with a power of 1000W running for 2 hours, that is, 2 degrees of electricity.
How long can the emergency portable power station with 2000wh energy storage be used for outdoor activities? This question is actually not difficult to answer, it mainly depends on the power of the electrical equipment. The greater the power of the emergency portable power station, the more it can meet the power demand of high-power devices, and the more electronic devices can be powered.
The larger the capacity of the emergency portable power station, the stronger the battery life of the outdoor energy storage power supply. The emergency portable power station that can store 2 kilowatt-hours of electricity will also support higher-power electrical appliances in terms of output power.
For example, rice cookers, electric ovens, kettles and other commonly used daily household equipment and most digital equipment can meet the requirements.
2. How to calculate the power supply duration of partastar emergency portable power station
Taking a 2000Wh emergency portable power station as an example, how many times can it charge a laptop or a projector at most?
1. Calculation of the number of times of use (for devices with batteries turned off, such as mobile phones, notebooks, etc.): electric energy * 0.85/equipment electric energy
Example 1: 50Wh notebook (off state): 2000Wh*0.85/50Wh≈34 times
2. Calculation method for charging while using the battery: electric energy * 0.5/equipment electric energy
Example 2: 50Wh notebook (using while charging): 2000Wh*0.6/50Wh≈24 times
3. Calculation of power supply time (equipment without batteries, such as: camping lights, electric fans, electric ovens, etc.): electric energy * 0.9/equipment output power
Example 3: 10W camping light (without battery): 2000Wh*0.9/10Wh≈180 hours
4. Why is it not 2000Wh/10Wh=200 times when calculating? Because when we use the outdoor energy storage power supply, there is a certain loss during operation, including the cooling fan in the power supply, the inverter and other accessories of the emergency portable power station itself are also working at the same time, so after many tests in the laboratory , the final calculation formula.
