The category of outdoor power supply is still quite popular abroad. Recently, due to some well-known reasons, people's concept of household energy storage is getting stronger and stronger, so the field of outdoor power supply has become lively. The author started with Cavanda +600 outdoor power supply, which attracted me for its multifunction, portability and long battery life. Look at the actual performance!
Cavanda power box is white with a white handle, which is easy to lift and carry. Product drawings are printed on the front, and the core selling point is "small size, large capacity".
On the back is a list of its core parameters, such as weight, size, input power and output power, as well as the capacity and model of the battery, which can be seen at a glance.
The accessories are relatively simple. In addition to the car body, there is also a 220V charging power adapter, a car charging input adapter and instructions. Taking out the body, we can see that the outdoor power supply in Cavanda is still very compact, and the color matching of red and black is calm without losing the sense of science and technology.
The overall shape is a rectangular cylinder with four corners and circular arc transition, which will not be injured by the corners of outdoor power supply when used or transported. Moreover, the measured overall weight is only 5.63 kg, and even girls can easily lift and carry it. An arc handle is specially set above the outdoor power supply in Cavanda for easy lifting.
There are cooling air outlets on both sides, which can effectively dissipate the heat inside the power supply to the outside, make the battery work at a safe temperature, and prevent the output power from decreasing or inducing safety problems due to overheating. However, the author thinks that the mesh area can be thinner to prevent small flying insects from entering in summer and increase the overall heat dissipation area.
There are thick rubber anti-slip pads at the four corners of the bottom, which can effectively increase the friction of outdoor power supply. The other four corners are raised about 1.5cm, which has the advantage that if there is water stain at the bottom, it will not enter the fuselage. As can be seen from the design details, Cavanda is still very careless.
Of course, as an outdoor "tool man", the functionality and interface richness of outdoor power supply are very important. What needs to be praised here is that Cavanda divides the front interface into six areas for different functions, and the list of functions is clear at a glance. From left to right are LED lights, display screen, DC input, DC input and output of 220V power adapter, USB interface group and 220V AC interface output.
Although LED bulbs are relatively small, the overall brightness is very bright. There are three modes: low brightness, high brightness and SOS flashing. Here, I will show you a high-brightness all-black scene. As can be seen from the above picture, this LED bulb can illuminate the living room with a size of 4 6 meters, and if it is tested outdoors, the lighting range will be larger.
Below the LED are the car charging output interface and two DC interfaces, which means that you can directly connect the outdoor power supply with the car charging adapter to supply power to your equipment. The output power of this interface can reach12v-16.8v10a.
On the right of DC output interface is USB group. Because there are more and more electronic devices, most electronic devices support USB interface charging. So this time, Cavanda directly supplies power to 1 PD interface and 4 USB interfaces, and this PD interface can realize 60W fast charging.
The author measured that charging Lenovo Xiao Xin Air 14 with C2C can realize 45W power, charging iQoneo 5 can realize 18W PD fast charging (65W is iQOO's private protocol), and charging iPhone XR with digital data cable. The successfully excited PD protocol may be limited by temperature, and the single test power is 12W.
In addition, the blue USB-A interface is a fast charging interface, which can successfully simulate QC fast charging protocol, Huawei FCP and Apple's fast charging after testing. For example, the charging treasure supporting QC can realize 20W fast charging, and the red rice Note 8 Pro supporting QC 18W can also realize 18W full blood fast charging. It can be seen that its compatibility is excellent, and the other three are ordinary USB interfaces. The power of 5V/2.4A can supply power for mosquito repellent lamps, LED bulbs and other small devices.
Above is the LCD screen, which shows the remaining battery power on the far left, the power wattage on the right, and the estimated available time at this power and wattage in the middle. At the bottom is the interface that is being powered on, and all kinds of data on the display screen can be seen at a glance. The circular hole on the right side of the LCD screen is the DC input interface of the 220V power adapter, and there are two AC interfaces below.
It is worth mentioning that there is a red button above each interface, which can control the power-on and power-off of the interface respectively, that is, you don't need to plug and unplug wires frequently at all. When not in use, just click the button to turn it off, which is very convenient to use.
After talking about functionality, let's talk about the charging, battery life and service life of outdoor power supply in Cavanda. For charging, it is equipped with a 220V power adapter and a car charger. The power adapter can achieve 90W charging power, which can be fully charged in about 5-6 hours, and the C port can achieve 60W PD fast charging, which can be fully charged in about 9- 1 1 hour. Both inputs can realize dual-channel fast charging of 130W, and the charging time can be shortened to 3-4 hours.
In terms of battery life, because its total capacity is as high as 626Wh, the length of battery life has a great relationship with the usage scenarios. You can also use the battery capacity/charge to roughly calculate the battery life in different scenarios. For example, a 30W car refrigerator can last for more than 20 hours, and a 200W rice cooker can last for more than 3 hours. If you are a drone pilot, you can charge your drone 33 times with Cavanda.
You can calculate the comprehensive battery life according to your own usage scenarios, but generally speaking, it is not a big problem for ordinary families to travel to meet the needs of mobile phone charging, cooking and lighting for one day and one night. Even if there is no electricity, there is a fast charge to charge the power supply when driving out. Therefore, Cavanda outdoor power supply meets the demand of long battery life on the basis of small size.
In terms of battery life, Cavanda's outdoor power supply uses automotive-grade 18650 batteries, and it is officially claimed that 1000 cycles can still have 80% battery life, which is similar to the lithium battery of mobile phones. But after all, outdoor power supply is not used every day like mobile phones, so it is estimated that the service life of outdoor power supply in Cavanda can reach about 3-5 years.
In terms of safety, first of all, the power supply will monitor the temperature of the fuselage in real time. When it reaches 55℃, the cooling fan will automatically start working to keep the fuselage at a low temperature level. In addition, the output power of the AC terminal is 600W (the peak value is 1000W). Once it exceeds 600W, the power supply will be automatically cut off, which ensures that the product will not be damaged due to overload and also ensures the safety of use.
In addition, Cavanda also has a set of software management system to ensure safe use, including temperature control, short-circuit protection, current protection, over-current protection, low-voltage protection and so on. Cavanda is very considerate in terms of security.
