Go out to relax with family and friends on the weekend, and come at any time to go away. However, as soon as you go out, you often need to worry about various digital equipment. The battery life of the portable projector is generally only one movie, so I started studying this outdoor treasure: outdoor power.
Outdoor electricity sources can really solve the problem of freedom of power consumption. You can also bring a computer temporarily adding a computer to camping, make a meal in the wild, bring an electric stove, and drink hot water to drink tea. The camping is also quite upper. You do n’t have to worry about buying it once or twice at all. You can only put ash at home.
1. What is outdoor power supply?
Outdoor power sources can be said to be an indispensable electric pet for outdoor enthusiasts. As a name, it is a mobile power supply, small portable charging stations, multifunctional power supply based on lithium ion batteries, whether it is camping or self -driving tour, etc. Realize the freedom of electricity.
Second, the purpose of outdoor power supply:
Why is this a treasure pet, because after understanding, I found that there are quite a lot of outdoor power supply. Below I will list outdoor power supplies:
Outdoor camping is the first scene to use outdoor power supply. This way you can heat the water, cook with rice cooker for cooking, and play the projector. Some camping points may not be prohibited from light fire. Bringing outdoor power can use hot kettle and rice cookers with peace of mind, and even work overtime is okay!
If it is a self -driving tour, it takes a long time to be outdoors. The outdoor power supply can be said to be a must -have artifact with various needs.
If the power outage is suddenly discharged at home, like the previous power limit, the outdoor power supply at home is particularly at ease.
In addition to the above, there are actually some special cases that need to be used. For example, you need to use electronic medical equipment for a long time, epidemic prevention work, outdoor mobile medical treatment, etc.:
It can also be used for outdoor operations, surveying, mapping, exploration, etc., and drones:
What is the difference between outdoor power and charging treasure?
Some people will say that outdoor power supply is a large charging treasure. In fact, there are still differences between outdoor power and charging treasures. The biggest difference is: the output method of electricity.
The charging treasure can only output the stored electricity in the form of 5V DC electricity. Outdoor power supply can reverse the stored electricity to 220V AC power output. At the same time, it also supports DC power output.
It can be said that if the charging treasure is a bicycle, the outdoor power supply is a new energy car!
4. Important parameters of outdoor power
1. Capacity
The capacity is particularly important! The larger the capacity of the outdoor power supply, the longer the power supply time!
The battery capacity is one of the most important performance parameters to measure the performance of the battery. It indicates that the battery releases the battery release under the corresponding prerequisite, that is, the battery capacity. Therefore, the greater the battery capacity of the outdoor power supply, the longer the power supply time.
By the way, the difference between MAH and WH:
The battery capacity of the charging treasure or the mobile phone is usually MAH (Mia), which means that the larger the battery capacity, the longer the battery life, and the outdoor power supply is generally used in WH (watt time). The conversion method of the person is different, so you need to convert it to the same unit to make intuitive contrasts.
Charging Treasure Unit: MAH [Na'Ah Time], generally referred to as [Mia]
Outdoor Power Unit: Wh [Watshi]
MAH is [Capacity] unit, and WH is [power]
The relationship between the two is: MAH × voltage ÷ 1000 = wh.
If the voltage is the same, the capacity of the same type of battery can be used by MAH, but if it is a battery of two different products, their working voltage is different, and they must be compared.
The unit of battery capacity is WH (wattime), 1 degree of electricity = 1000Wh, and most of the common power capacity on the market is about 1000Wh.
However, the greater the capacity, the heavier the fuselage. In order to facilitate us to carry, it is best to choose the capacity that suits us.
2. Power
It depends on whether it is the rated power. The rated power refers to the power of the power supply for a long time. It is the most important standard in the power power. Some merchants are the maximum power, not the rated power. What electrical appliances can drive.
Power represents Watsi (W), which is different from Watshi (WH) and MAH (MAH). Watshu represents the output power of outdoor power. It is recommended to choose a power supply of more than 500W.
If you need to drive 100W projectors and 300W small rice cookers, choose 500W outdoor power supply;
If you need to drive a 1000W electric kettle and induction cooker, select outdoor power supply above 1000W or more;
If you need to drive a 1300W microwave oven and 1600W electric oven, choose outdoor power supply of about 1200W-2000W.
3. See the type and quantity of the power supply port
AC port: 220V AC communication, can connect to various electrical plugs in sockets
USB port: support mobile device, mobile phone charging
Type-C: Huawei port, supports laptops
DC port: straight to port
Car charging: Can be charged on the car for power supply
PD, QC: Quick charge, improve the charging efficiency of mobile devices
4. Shell
It is very important to choose the outdoor electricity shell material. Generally, it will be brought to the outdoors to bump, be squeezed to or hit, so a solid and durable shell is needed.
Therefore, in the purchase of outdoor power supply, the shell material is also very important. Generally, there are: plastic shell, aluminum all -hell shell
Plastic shell:
We all know that the insulation of plastic is very high, so the plastic shell can effectively avoid leakage, but the plastic shell is not highly resistant and easy to break.
Aluminum shell:
The aluminum alloy shell has the advantages of fire prevention and waterproof and durability, which can effectively prevent cracking and impact. It is more abrasion -resistant and is more suitable for the wild environment. The disadvantage is that the cost is too high and the maintenance difficulty is high.
5. Charging method
At present, most outdoor power supply has the first three methods:
City power charging, that is, AC AC charging
Car charging
Solar charging
Charging machine charging
6, volume and weight
The advantage of outdoor power is small volume. It can be carried like a small box. It is not afraid of occupying space in the car, and it is relatively light.
7. Look at the additional points
See if there are LED lights, can be used as a family backlight or outdoor lighting
See if there is a mobile phone APP remote monitoring function, you can control the switch through the mobile phone
See if you can support wireless charging, you can pay more attention if you have this demand
Looking at the appearance, the appearance is quite important for Yan control, the most perfect coexistence of strength and face value
See if the shell is wear -resistant and can carry
5. Precautions for outdoor power supply
It is recommended to choose a big brand so that there is a security guarantee. Outdoor power supplies need to pass the relevant battery certification to ensure safety. The important point of the outdoor power supply is the battery cell. The good battery cell life is long, the performance is stable, and the temperature is protected. The quality and protection function of batteries can reduce hidden safety hazards, and be sure to stay away from inferior products.
There is no need to charge the electricity every time, and the battery that is not used for a long time is also charged into a certain amount of electricity before storing it to avoid excessive discharge damage to the battery.
It is recommended to store it in a dry and cool environment. The temperature is the best at (0-40 degrees). Try to avoid humidity and high temperature as much as possible.
