Important parameters of outdoor power supply
1. Capacity
Capacity is especially important! The larger the capacity of the outdoor power supply, the longer the supply time!
Battery capacity is one of the most important performance parameters to measure battery performance. It refers to the amount of energy released by the battery under corresponding conditions.
The capacity of the battery. So the larger the battery capacity of an outdoor power supply, the longer it will last.
Here’s the difference between mAh and Wh by the way:
The battery capacity of a power bank or mobile phone is usually mAh(mah), meaning that the larger the battery capacity, the longer it lasts, whereas outdoor power sources are generally used
Wh(watt-hour), mAh, and Wh are all units of battery capacity, but the way they are converted is different, so you need to turn
Let’s put it in the same unit so we can do a visual comparison.
Unit of power bank: mAh [mah], also known as mah for short
Outdoor power unit: Wh【 watt-hour 】
mAh is the unit of capacity and Wh is the amount of electricity.
The relationship between the two is: mAhx voltage ÷1000=Wh.
If the voltage is the same, you can use mAh to compare the same battery capacity size, but if it is to compare two different products of electricity
Pool, their working voltage is not the same, will use Wh to compare.
The unit of battery capacity is Wh(watt-hour), 1 kilowatt-hour = 1000Wh, most of the common power supply capacity on the market is about 1000Wh.
However, the larger the capacity, the heavier the fuselage will be. In order to facilitate our carrying out, it is better to choose the capacity suitable for us.
2. Power
To see whether it is rated power, rated power refers to the long-term stable output power of the power supply, is the most important standard of power supply, some
Business target is the maximum power, not rated power, power size indicates the use of outdoor power supply range, determine what it can drive electricity
A surname.
Power stands for wattage (W), which is not the same as watt-hours (Wh) and milliamps (mAh), which represent the work output of an outdoor power source
Rate, recommended to choose more than 500W power supply.
If you need to drive 100W projector and 300W small rice cooker, choose 500W outdoor power supply;
If you need to drive 1000W electric kettle and induction cooker, choose the outdoor power supply above 1000W;
If you need to drive a 1300W microwave oven and a 1600W electric oven, choose an outdoor power supply of 1200W to 2000W.
3. See the type and quantity of power supply ports
·AC port: 220V AC, which can be connected to various electrical plugs
·USB port: Support mobile devices, mobile phone charging
·Type-c: Huawei port, supporting laptops
·DC port: direct flush port
· Car charger: It can be placed on the car to charge the power supply
·PD, QC: fast charge, improve the charging efficiency of mobile devices
4. Shell
Choose outdoor power supply shell material is very important, generally brought to the outdoors will bump, be squeezed to or impact, so there needs to be a firm
Solid and durable shell.
So in the selection of outdoor power supply, the shell material is also very important, generally there are: plastic shell, aluminum gold shell
Plastic case:
As we all know, the insulation of plastic is very high, so the plastic shell can effectively avoid leakage, but the plastic shell resistance is not high, also
It breaks easily.
Aluminum alloy shell:
Aluminum alloy shell has the advantages of fire, waterproof and durable, can effectively prevent cracking and impact, wear resistance is relatively strong, to the field environment
Would be more suitable. The disadvantage is that the cost is too high and the maintenance is difficult.
5. Charging mode
At present, most outdoor power supplies have the first three ways:
· Mains charging, namely AC charging
· Vehicle charging
· Solar charging
· Generator charging
6. Volume and weight
The advantage of outdoor power supply is small size, like a small box can be carried, in the car is not afraid of space, but also relative
Light and light.
7. Look at the bonus points
· Check whether there are LED lights configured, which can be used as home backup lights or outdoor lighting
· Check whether there is remote monitoring function of mobile APP, which can be controlled by mobile phone
· Check whether wireless charging can be supported, and pay more attention if there is such a need
· Look at the appearance, appearance is very important for Yan control, strength and appearance level coexist perfectly
· Check whether the shell is wear-resistant and can be carried
