In recent years, due to the epidemic, self-driving tour, camping has become a lot of people’s weekend, holiday travel choices, outdoor power is also a good thing to be added to the shopping list, but novice contact outdoor power is a face of confusion, do not know how to choose. As a backcountry camping enthusiast who has personally used outdoor power sources many times, I think beginners should focus on these points when choosing an outdoor power source.
Power: The more power can be powered by more equipment, the more content of outdoor activities. For example, the power of our camping rice cooker and electric cooker is generally 500W or above, which requires a power supply of more than 500W to drive. We can choose different power outdoor power supply according to their travel needs.
Battery capacity: I also stepped on the pit to know that the original battery capacity can only represent the outdoor power can store battery capacity, and determine the discharge capacity of outdoor power and power function of the core parameter is “battery energy”! So we must pay attention to, when buying outdoor power can not only look at the battery capacity.
Battery type: Outdoor mobile power battery mainly includes ternary lithium battery, lithium iron phosphate battery.
At present, the most used in the market is three-way lithium battery. The better high-end brand will use lithium iron phosphate battery. It is recommended that you give priority to lithium iron phosphate battery when choosing.
Additional functions: Other additional functions are mainly the weight, volume and power supply of outdoor power supply. On the basis of the above excellent performance, the lighter the weight, the smaller the volume, the more convenient to carry. There are wireless charging, solar charging, gasoline charging and other charging methods, the more diverse charging methods, the better.
Outdoor power functions can be simply divided into two categories: DC output and AC output.
The DC output includes USB-A ports, USB Type-C ports, and 12V car charger ports. Some outdoor power supplies support DC5521 ports or none
Line filling.
AC output is often said to be 220V AC output, the current market, AC output power from 300W to 3000W are available.
Requirements can also be simply divided into two categories by function: those that have specific power requirements for AC output and those that do not.
For the first type of users, focus on: the rated power of outdoor power supply, to cover their own commonly used electrical equipment rated power. For example
Camping, most of the time bubble tea, roast meat, hand electric kettle rated 1000W, electric oven rated power
1500W, then pick an outdoor power supply rated at 1500W.
Some friends may want to do it all at once. In case one day you need to show your skill to operate a 3000W hammer drill, why not choose one
3000W outdoor power supply. However, the 3000W model is larger and heavier than the 1500W model, so there is a high probability that it will be used for a long time
Eat ash. On the other hand, the 3000W model drives 1500W electrical equipment, which is not a “dimensionality reduction attack”. On the contrary, the conversion efficiency is better
Low. If the 3000W inverter drives the 3000W power device, the conversion efficiency is 95%. If the 1500W inverter drives the power device, the conversion efficiency is only 95%
70%. This is determined by the implementation principle of the inverter module itself.
A word of caution here:
The above mentioned estimation method is only applicable to resistive loads, inductive loads and capacitive loads starting current is at least rated operating current
3~7 times, so the rated power of the outdoor power supply should be multiplied by at least 2, to take the move, otherwise it will start the current protection, directly shut down.
For the second type of users, mainly as a large power bank to use, basically, entry-level products can meet the needs. If it’s about endurance or
Charging times have requirements, can be simply calculated. A laptop with a 40Wh battery will probably work on a full battery
3 hours, a 400Wh outdoor power supply, pure theoretical calculation, can be charged 400/40=10 times, use 10*3=30 hours.
Need to remind, small power products, such as laptops, if support type-c port direct charging, direct user external power supply C port charging
Electricity is better. If an adapter is used, the outdoor power supply will first convert direct current into alternating current, resulting in conversion losses.
