Micro-arc oxidation (MAO) is a more advanced form of anodic oxidation, which is also known as plasma electrolytic oxidation (PEO), or electrolytic plasma oxidation (EPO). It's a surface ceramization technology with a higher-quality coating.
The principle is that via the arc discharge, the instantaneous high temperature, and the high-pressure effect, as well as matching the electrolyte and the corresponding electrical parameters to grow a matrix metal oxide-based ceramic film layer.
Micro-arc oxidation solves some of the defects of anodic oxidation, and greatly improves the overall performance of the film layer, including corrosion resistance, wear resistance, high-temperature resistance, electrical insulation, etc., and is relatively more environmentally friendly. Thanks to the simple and stable process, it's easy to control the film thickness.
Why is the micro-arc oxidation more abrasion-resistant and corrosion-resistant than anodizing finish?
The coating is a chemical conversion of the substrate metal into its oxide and grows both inwards and outwards from the original metal surface. Because it grows inward into the substrate, it has excellent adhesion to the substrate metal. A wide range of substrate alloys can be coated, including all wrought aluminum alloys and most cast alloys.
The disadvantage is that it is operated under higher voltage, and safety is a major concern. At the same time, the temperature of the electrolyte rises faster and requires a larger capacity of refrigeration and heat exchange equipment. Additionally, the cost of micro-arc oxidation is a bit more expensive than anodizing.
The P25 V2.0 Micro-arc oxidation version is a 3600 lumen palm-sized floodlight with a micro-arc oxidation finish, making it extremely abrasion-resistant and giving it a distinct look with premium texture.
The pocket-size torch, equipped with a CREE XHP70.3 LED and powered by a 1*5000 mAh rechargeable 21700 battery, has broken the brightness-to-volume ratio barrier in single-LED flashlights.
As a bonus, the humanized moonlight mode allows you to use it in the middle of the night without blinding or disturbing others.

Q2. What is the difference between Micro arc oxidation and anodizing? Micro arc oxidation VS anodizing
A: Please see the comparison sheet below:
| Technology | Anodizing | Micro arc Oxidation (MAO) |
| Overview | Anodizing is a common surface treatment process for metals such as aluminum alloys, which can not only produce rich color effects, pattern texture, and other decorative but also has functional effects such as protection itself. It is an electrochemical reaction in which the metal is placed in a specific electrolyte and an applied current forms a stable oxide film on the anode, which can be colored in a variety of ways before being sealed. | Micro-arc oxidation (MAO), a more advanced form of anodic oxidation, also known as plasma electrolytic oxidation (PEO), or electrolytic plasma oxidation (EPO), is an electrochemical surface treatment process for generating oxide coatings on metals. It is similar to anodizing, but it employs higher potentials so that discharges occur and the resulting plasma modifies the structure of the oxide layer. This process can be used to grow thick (tens or hundreds of micrometers), largely crystalline, oxide coatings on metals such as aluminum, magnesium, and titanium. Because they can present high hardness and a continuous barrier, these coatings can offer protection against wear, corrosion, or heat as well as electrical insulation. |
| Advantages | The anodic oxidation process can form a dense film layer on the metal surface, which can improve mechanical properties, wear resistance, weather resistance, insulation, bonding with the coating, and other functionalities, as well as color and patterning as a product appearance decoration. | Micro-arc oxidation solves some of the defects of anodic oxidation, and greatly improves the overall performance of the film layer, including corrosion resistance, wear resistance, high-temperature resistance, electrical insulation, etc., and is relatively more environmentally friendly. Thanks to the simple and stable process, it's easy to control the film thickness. |
| Disadvantages | Poor appearance may occur during the manufacturing process due to material adhering together, impurities in the oxide film, electrolysis temperature too high or time too long, and so on. | The disadvantage is that it operates at a higher voltage, which raises safety concerns. At the same time, the electrolyte temperature rises faster, necessitating a larger capacity of refrigeration and heat exchange equipment. |
| Cost Reference | The price of product pieces varies greatly for a variety of reasons, and the size and structure of the sample pieces may also vary. At present, there is billing based on the number of pieces as well as the acreage. Some larger processing plants may charge more for the same product. Analysis of anodizing process costs: 37% of chemical materials, 20% of energy consumption, and 35% of environmental protection costs. | In general, the process cost of micro-arc oxidation is higher than that of traditional anodizing, roughly 20% higher. The main reason is that the liquid replacement cycle in the oxidation tank is shorter. It is much higher in the automotive and aviation industries, ranging from 50 to 120%. And it is more expensive for wheel axles, etc., by about 240 to 360%. |
| Points to Note for Design | First of all, in terms of applicable materials, anodizing is mostly used on the surface of some metal products, particularly aluminum alloy, magnesium alloy, and so on. Some metals, such as stainless steel, should not be anodized. The function of anodic oxidation is primarily to color and improve the surface performance of the original product, and the comprehensive cost to decide whether to use this process to ensure cost-effectiveness. At the same time, we should pay attention to the sulfuric acid concentration, electrolysis length and temperature, surface damage, metal substrate composition, electrolyte impurities, and other factors during the process to avoid a large number of defective products and increase costs. |
The process influences micro-arc oxidation depending on the product development direction. For example, the composition of the material structure, lightness, and thinness. Micro-arc oxidation, as opposed to anodizing, is applicable to a wider range of metal materials and focuses more on the functionality of the film layer. As a result, this process can be used to design products that require a higher surface performance, such as wear-resistant, heat-resistant, higher strength parts, and so on, as well as products that require customized or special treatment. Micro-arc oxidation can also be used for decorative purposes, such as color matching. When using it, we must consider the surface condition of the metal material, the electrolyte composition, the voltage and current density, the temperature and time, and so on. |
| Applications | The application range is extremely wide, including the electronic products field, such as cell phone frames, notebook shells, smart wear shells, electronic cigarette shells, etc.; the construction field, such as facades, wall top surfaces, etc.; home appliances and home field, such as the shell of small and large home appliances, door handles, bookshelves, lampshades, etc.; automotive field, such as wheels, central control panel, trim, etc. | Mainly used in the field of defense and aerospace, such as military weapons, wearable devices, and satellites; electronic products, such as laptop computer shells, chassis shells, etc.; automotive and other transportation fields, such as bicycle frames, car piston seats, cylinders, wheels, etc. |
Q3: What is a Moonlight Mode on an Outdoor or EDC Flashlight?
A: Moonlight mode is a flashlight's lowest brightness level, usually 5 lumens or less. Some flashlights even have moonlight modes that are 1 lumen or less, 0.5 lumens, or even 0.2 lumens.
A: If you've never used a moonlight mode before, you might be wondering what the point of having so little light is. While a moonlight mode may appear to be of little use, a small amount of light can make all the difference in the dark. A moonlight mode allows you to see in the dark without blinding or disorienting yourself or others, and it has a low impact on your night vision. So let me show you some examples of moonlight mode in action.
Moonlight modes are especially useful outdoors and are an excellent feature for camping for a variety of reasons. This small amount of light allows you to navigate in the dark without disturbing your night vision or your camping companions. So, if you want to read in the tent at night while your buddy sleeps, a moonlight mode is ideal. Also, if you wake up in the middle of the night and need to use the restroom, moonlight mode will illuminate the path in front of you without disturbing your companion or interfering with your night vision. Not to mention that it won't be bright enough to wake you up.
Moonlight mode is also useful for close quarters when using an LED flashlight. Even 30 lumens at night in a shared small tent can be too bright for those inside. A moonlight mode is ideal for looking around your tent or inside your camping bag. You can see clearly in front of you without fear of injuring your or others' eyes. In addition, moonlight modes frequently have absurdly long runtimes. A moonlight mode is a way to go if you want to save battery life. For example, the P25 V2.0 can last 80 hours continuously on moonlight mode.
Along the same lines, you don't have to be outside in a tent to enjoy moonlight mode. Moonlight mode can be extremely useful when working around the house in a small space. The pipes under my sink, for example, were making noise the other day, and moonlight mode provided just enough light to see what was going on. If I had been standing under my sink and shone even 50 lumens at my pipes, the glare would have been unbearable.
Finally, a moonlight mode is ideal for concealment. A moonlight mode can help you navigate in the dark if you don't want to draw attention to yourself. This is especially useful for police officers and hunters who must navigate in the dark in a discrete manner. Not only that, but it provides just enough light to search through a tactical or hunting bag for whatever the user may require.

Q6: Is P25 V2.0 USB rechargeable?
A: No, the 21700 flashlight P25 is not directly USB rechargeable. But it comes with a 5000mAh 21700 battery with TYPE-C charging port on top, which allows each charging with the cable and a 5V adaptor.
Q7: What kind of adaptor can I use to charge my P25?
A: Please use the adaptor with an output voltage of 5V, either current of 0.5A, 1A, 2A, or above would be OK to use. The difference would be different charging time. 5V/0.5A would take about 11 or 12 hours for a full charge, while 5V/1A takes about 5.5 hours, and 5V/2A or above would take only 3 hours.
Q8: How can I know if my light is fully charged or not?
A: There is an indicator on top of the battery positive pole. It would show red during charging and turn green once the battery is fully charged.
Q9: Why does the torch flicker during use?
A: The torch flickering during use generally hints a low battery power. To remind users of battery replacement or charging in time, the torch will flicker 3 times every 5 minutes.
Q10: Why can't my 3600 lumens LED flashlight enter Turbo sometimes?
A: There are 2 possible reasons.
1) Intelligent overheat protection based on time and temperature.
When the light works on the Turbo mode for 2 minutes, it will automatically switch down to 1600 lumens to avoid overheating. Also, when the heat is over the safety data, the output will automatically step down to reduce heat. When the temperature is lower than the safety value, the output will gradually increase.
2) Low-voltage downshift
When the voltage is lower than 3.0V, the flashlight will automatically step down to a lower brightness level till the battery runs out to reserve more runtime.
