Portable power station, also known as portable outdoor power supply, is a large-capacity mobile power supply device that can solve the power demand in a non-urban power grid environment. It plays an important role in application scenarios such as homework. Therefore, if you want to enjoy a high-quality outdoor life, "power freedom" is particularly important. But many people have no idea about how long do power supplies last.

So, as a user of an outdoor power supply or a consumer who is about to purchase an outdoor power supply, do you know how long do power supplies last? What is the battery life of the outdoor power supply? Everyone must want to know the answer to these questions about the outdoor power supply, let’s take a look together !

How long do power supplies last depends on its output power

The greater the power of the power supply, the more high-power devices can be satisfied, the more electronic devices can be powered, and the more outdoor activities can be performed. Power refers to the energy consumed by a device per unit of time, usually expressed in watts (W). The power supply of our brand covers from 150W to 1000W.

When selecting the power of the outdoor power supply, it needs to be selected according to the actual usage scenario. The following are the applicable scenarios of different power outdoor power supplies:

1. Low power (150W-300W): suitable for charging mobile phones, tablet computers, small digital devices, etc., and can meet the needs of daily outdoor activities.

2. Medium power (300W-600W): suitable for charging laptops, small rice cookers, electric kettles, etc., and can meet the needs of outdoor office and camping.

3. High power (1000W and above): It is suitable for charging high-power devices such as refrigerators, washing machines, and projectors, and can meet the needs of outdoor camping and mobile office.

How long do power supplies last also depends on its battery capacity

Outdoor power capacity refers to the total amount of electrical energy that can be provided to external devices, usually expressed in milliamp hours (mAh) or watt hours (Wh). The larger the battery capacity, the longer the battery life of the outdoor power supply and the longer the power supply. How big is the outdoor power supply capacity is the decisive factor in answering the question of how long do power supplies last. Long-distance outdoor travel has very high power requirements, so it is usually recommended to use a large enough outdoor power supply for power supply. The outdoor power supply that can store one degree of electricity will also support the power consumption of larger power appliances such as rice cookers, electric ovens, kettles, etc. in terms of output power.

For example, if you have a power bank with a capacity of 400Wh, a built-in lithium battery, and a connected device with a power consumption of 40W, then ideally the power bank can supply 400Wh / 40W = 10 hours, that is, 10 hours of continuous use.

Note that actual conditions may vary. The rated capacity is only the theoretical value of the power supply. In actual use, it is affected by factors such as the energy efficiency of the power supply itself and the charging efficiency of the device.

Taking our power supply as an example, the usage time of using power supplies of different specifications and models to supply power to different devices is as follows:

A power supply with a power of 300W and a capacity of 230Wh: a 40W device such as an AC fan can supply power for about 6 hours, a 50W device such as a laptop can supply power for about 5 hours, and a mobile phone can be charged for about 19 times.

A power supply with a power of 600W and a capacity of 540Wh: a 100W device such as a projector can provide power for about 5.4 hours, a 300W device such as an electric drill can provide power for about 2 hours, and a mobile phone can be charged for more than 45 times.

A power supply with a power of 1000W and a capacity of 888Wh: 150W devices such as LCD TVs can provide power for about 5-6 hours, 500W devices such as rice cookers can provide power for about 2 hours, and mobile phones can be charged for about 75 times.

Consumers will consider many factors when choosing an outdoor power supply. The first thing to consider is the outdoor electricity usage scenario, whether to go fishing outdoors, set up a stall outdoors, use electricity for cooking on a self-driving trip, or go camping overnight. The time of use is different, and the outdoor power supply required is also different. To sum up, how long do power supplies last is a matter of great concern to everyone. The power and battery capacity of the outdoor power supply are the key factors affecting the use time. When choosing an outdoor power supply, you need to choose the appropriate capacity and power according to your own needs and actual conditions, and pay attention to the conversion efficiency and brand reputation of the equipment to achieve the best use effect. Hope this article can provide a useful reference for you when purchasing outdoor power supplies.
