Today we will talk about an interesting topic, how to charge the outdoor power supply in the field.
In recent years, outdoor power supply has gradually been accepted by everyone, and it can often be seen in camping and self-driving tours, but if you work or live in the field for a long time, it is inevitable that there will be power anxiety. Solar energy may be a near-perfect way to replenish electricity, clean, pollution-free and inexhaustible.
Today, take the current market hot Zhenghao EcoFlow de DELTA Max and electric small two outdoor power supply 1800W as an example to talk about how to ask the sun to "borrow" electricity.
Parameter comparison
Before starting, let's briefly understand the next two products, Zhenghao EcoFlow DE DELTA Max (hereinafter referred to as DE DELTA Max) positioning is an all-round flagship, the battery capacity reaches 2016Wh, the simple understanding is 2 degrees of electricity, the whole machine has a total of 13 output interfaces, up to 13 devices can be powered at the same time. The AC output is rated at 2400W with peaks up to 4600W. Not only can it meet the daily charging, but also load more powerful professional tools.
The battery capacity of the 1800W outdoor power supply is 1534Wh (about 1.5 kWh), and the total output interface is 6, which can power up to 6 devices at the same time. The AC output is rated at 1800W in kilometers and 3600W at a peak, which is slightly smaller in both the number of interfaces and the output power compared to Zhenghao.
In the specific output parameters of the two products are also different, de DELTA Max has USB slow charge / fast charge, in addition to mobile phones can also be convenient to power action cameras, wireless microphones, camping lights small current equipment. In addition, there are 2 USB-C PD fast charge, power up to 100W, fully considering the support for high-power notebooks, such as mobile workstations and game notebooks, etc., in the outdoor can also cut video to play PUBG, and up to 4 national standard five-hole 220V AC output port even if you go camping, do not have to worry about not enough.
In contrast, the electric small two outdoor power supply 1800W of 2 USB slow charge and 1 USB 60W is difficult to meet the needs of the current mobile phone fast charging, 2 220V AC output can only be said to be barely enough.
The significance of high-power outdoor power supply is to solve the user's electricity demand in the outdoor, sometimes users do not know what electrical appliances will be brought, the rated power of de DELTA Max is 2400W, and it can stably drive 3000W super power under the support of exclusive X-Boost up-dimensional drive technology, and the peak power can reach 4600W. 99% of the appliances in life are supported, including ovens, microwave ovens, electric cake pans, and even two 1.5P air conditioners.

Measured solar panels
The sun may be the most perfect clean energy for human beings, does not consume fossil fuels, does not produce noise, and more importantly, is inexhaustible, and even some car manufacturers equip cars with solar charging systems. The advantage of solar energy is naturally favored by outdoor power supply manufacturers, and Zhenghao EcoFlow and Electric Xiao'er both provide solar charging panels.
Zhenghao EcoFlow has a single group of 160W, 220W and 400W three products, the conversion efficiency is 22%, the figure is a single group of 220W products, the actual measurement can reach 137W, if it is a strong summer of sunlight, the data will be better.
According to official data, when two 400W solar charging panels are connected in series, the full time is only 3.2 hours.
What is more interesting is that Zhenghao 220W solar panel adopts double-sided power generation technology, that is, both sides can generate electricity, 220W on the front and 155W on the back, which is the first application in the portable folding solar panel. Under the same lighting conditions, Zhenghao 220W solar panels can use the scattered light of the surrounding sunlight and the reflected light of the ground on the back to increase the solar power generation power through the solar panels on the back, and the gain range is 5-25% depending on the environment.
The picture shows the electric small two solar energy 200W solar charging board, the electric small two only 200W and 100W two specifications.
The measured output is 109W, official data, and it takes about 4.5 hours to fill with two 200W solar charging panels at the same time, subject to the limited charging power, although the battery capacity is smaller, but the charging time is longer.
It is not difficult to find that Zhenghao EcoFlow's solar charging panel power is greater and the actual efficiency is higher, and taking into account the efficiency of double-sided power generation, the power of the small two is slightly lower, it takes longer, whether it is a professional use, such as field expeditions, exploration or long-distance self-driving trips, the former is more suitable, after all, the outdoor weather is changeable, and the short-term high efficiency of charging will not let the experience be discounted.
Fast charging that cannot be ignored
Many people choose to buy power supply will often ignore the charging efficiency, do not know that the charging efficiency will also directly affect the experience,
Electric small two outdoor power supply 1800W standard charger power is 300W, from zero full need 6.5 hours, the time is not very long, but if you accidentally forget to charge can be troublesome. Fortunately, the manufacturer provides a dual charging interface, which can support two charger charges at the same time. Dual-charge mode can be fully charged in as fast as 2.9 hours.
It should be noted that another charger needs to be purchased separately.
Strictly speaking, the fast charging of the electric small two can not be regarded as "real fast charging", compared with the German DELTA Max is much simpler and more direct.
Without a bulky power adapter, and without the need for an obscure dual-charge interface, an ordinary power cord can no longer be connected to a mains outlet to charge it.
Zhenghao EcoFlow exclusive patent X-Stream fast charging technology, the official data charging power can reach 2000W, from zero full charge only 1.6 hours, measured power supply of 86%, charging power is 1570W, if the electric small two is compared to high-speed railway, then this is a civil aviation airliner. In terms of charging safety that everyone is worried about, Delta Max provides eight kinds of protection such as high temperature protection, low temperature protection, overcurrent, overload, overvoltage, over-discharge, short circuit, battery protection and other software and hardware means such as high-rate automotive batteries and BMS intelligent battery management systems, ensuring safety and effectively improving battery cycle life.
Considering the large power demand of some users, Delta Max also supports external battery packs, which can connect two power packs with a capacity of 2016Wh at the same time, reaching a terrifying power of about 6 degrees.
Delta Max also supports remote control of mobile phone APP, the power supply comes with WiFi and Bluetooth, and the mobile phone can understand the working status of the power supply and upgrade the OTA firmware.
Comprehensive reviews
From the overall point of view, the German DELTA Max is better than the electric small two outdoor power supply 1800W.
If you are a professional self-driving enthusiast, or an industry user, pay attention to the high power output, number of interfaces and charging efficiency, the choice of DE DELTA Max is indeed more appropriate.
The electric small two outdoor power supply 1800W gives me the feeling that it is an ordinary user who occasionally uses high power and is insensitive to the expansion interface and efficiency.
But then again, it's already at this level, why not better, you say.
