1. Capacity
The first thing to look at when choosing an outdoor power supply is the capacity of the outdoor power supply. The capacity ensures how long your outdoor power supply can be used outdoors. How can I determine how much capacity of outdoor power supply I want? The capacity of outdoor power supplies on the market is mainly 300-2000Wh. If it is used for short-term camping without overnight, it is enough to choose an outdoor power supply of 1000Wh; if you want to camp overnight, it is recommended Choose an outdoor power supply of 1000Wh and above; if you are going on a self-driving camping trip, it is recommended to choose an outdoor power supply above 1500Wh. When choosing an outdoor power supply, it is recommended to equip a suitable solar panel to supplement the power when the outdoor power supply is out of power.
2. Power
Before choosing an outdoor power supply, you must first understand the power of each electrical appliance you need for outdoor camping, and then choose an outdoor power supply with the corresponding power according to the power of the electrical appliances. The power of electric cooking pots, electric hot pots, induction cookers and hair dryers for outdoor camping is generally 600-1200w; the power of electric appliances such as car refrigerators, electric fans and table lamps is generally within 120w; the power of electrical appliances such as mobile phones, tablets and laptops is generally 80w within. The power mentioned in the outdoor power supply is the total power of all the electrical appliances used at the same time. Therefore, you must first understand the approximate power of the electrical appliances you need, and then choose the appropriate outdoor power supply according to the total power.
3. Battery
The batteries for outdoor power supplies on the market are mainly ternary lithium power supplies and lithium iron phosphate batteries, both of which have their own characteristics.
Lithium-ion battery uses lithium as the negative electrode active material, and has high electromotive force and specific energy. It is an energy storage device integrating high energy density and high voltage. The main features are large capacity and good stability. Lithium iron phosphate battery is a lithium ion battery that uses lithium iron phosphate as the positive electrode material and carbon as the negative electrode material. The main features are high working voltage, high energy density, long cycle life and good safety performance. The 1C cycle life of lithium iron phosphate battery is more than 2,000 to 3,500 times, and the energy storage market requires more than 4,000-5,000 times, ensuring a service life of 8-10 years.
4. Volume and weight
The outdoor power supply is of course to be taken out for use, so its weight is also a point that needs to be considered. No one wants to go out with a large and cumbersome power supply. Generally speaking, the volume and weight of the outdoor power supply are directly proportional to the battery capacity, the larger the battery capacity, the greater the corresponding volume and weight. Before we choose an outdoor power supply, we must first understand the volume and weight of the outdoor power supply to see if we can accept it, and then decide whether to choose this outdoor power supply.
Mobile portable energy storage (lithium battery) power supply has a variety of output methods, one is enough to meet the needs of various small electrical appliances and electronic products, no matter the application scope of location shooting, self-driving camping, outdoor dinner, emergency power supply, etc. Be applicable.
