Whenever night falls, darkness always comes as expected. I would carry a flashlight with me, and a strong light would come on and cut through the dark curtain. With this light, walking through the forest and crossing the alleys is also quite interesting. The pit flashlight has been in the pit for more than a year, and the most common natural thing to say is to count the EDC flashlight. AA small tubes, key flashlights, and commuters are all carried with them over the years. Today I want to share with you is the latest launch of the 21700 flashlight X4M from the domestic label "On the Road", which is known as the shortest with direct charging. As the first launcher of the X4 series, let's take a look at its specific performance:
The product packaging adheres to the simple style design that has always been on the road, and is highly recognizable by the brand. However, on the basis of the eye-catching box painting, the words 21700 USB are deliberately marked below, indicating that it is a 21700 flashlight with USB direct charging function.
Through the function icon on the side of the box, you can understand that its main selling points are USB-C direct charging, jumping self-defense (that is, supporting flashing, which can cause instant blindness, and can be used for self-defense in emergency moments), 10.9cm (fuselage length) and no flicker (No Flicker).
In addition, you can also see the X4K/X4M logo, of which the unreleased X4K uses 5 LED lamp beads, which is worth looking forward to.
In terms of accessories, manufacturers have always given a lot, in addition to the flashlight body, there are also supporting batteries, hand ropes, clips (two-way), charging cables and iconic black thick soft cloth storage sleeves (in fact, personally feel that getting a nylon sleeve can be hung on the waist is also good).
As a 21700 small straight, the X4M has a barrel length of only 108mm, and the diameter of the barrel and the barrel head is 25.4 and 30mm respectively. Held in the hand, it is a completely portable size, and it will not be a burden to tuck in the pocket of your pants or coat.
Friends who have used or are familiar with the "on the road" flashlight will always have a sense of déjà vu when they first started X4M. This, of course, is due to its uniform design. The whole flashlight is a hard anodized aluminum alloy shell, durable and anti-wear. Its color is bronze matte, the bright silver metal side press in the center, the 6 heat sinks around the barrel head, and the chocolate block knurled treatment on the middle cylinder. The nut-shaped tail cap is beautiful and easy to twist.
Side press with indicator light, red is charging, blue when full, and accompanied by a remaining battery reminder each time it is turned on. Because the button is slightly convex outward, in order to avoid accidental touch when storing, the default long press on the switch machine (last 10 seconds can open the "child lock"), tap to switch gears, double click super bright, three hits can activate the pop/beacon. The operation logic is as usual, simple and easy to use.
Nowadays, the direct charging function has become the mainstream equipment of flashlights. It is undoubtedly much more convenient than ever to remove the battery and charge it through a special charger. Flashlights on the road are also equipped with this function as standard. The thick stopper guarantees a good seal.
The charging port is a Type-C socket that can be plugged in blindly (it should be known that there are still many so-called direct charging flashlights that still use the old MicroUSB port). The X4M has a waterproof rating of IPX6 and a drop-proof height of 1 meter. Enough to cope with the wind and rain and accidental falls in the daily outdoor environment.
In order to minimize the length of the barrel, the X4M adopted a light cup design and eliminated the magnetic suction on the tail cover (the hand rope hole was not added). This is certainly a compromise, but it also leads to a length that is more suitable for holding an easy-to-carry flashlight.
The above figure shows the length of the flashlight and the battery, and it can be seen that the manufacturer has reached the limit of the length of the flashlight. The standard battery has a capacity of 5,000 mAh and can last for two hours even when it is super bright.
The wall of the flashlight is also relatively thick, and the thread is silky and smooth when screwed. The entire flashlight weighs 68 grams. Of course, it can also be powered by an 18650 battery, but it needs to be purchased separately.
Battery tail cover spring close-up:
Stainless steel pressure rings, also not aggressive. The X4M has three types of LED beads to choose from, namely SST40, XHP50.2 and SFT40. The SFT40 has a maximum range of 238 meters and 3,000 lumens at extreme brightness. The SFT40 version was chosen because it can take into account a certain long-range shooting capability. Friends who want to have a big flood can directly start with version 50.2.
The design of the barrel head for the orange peel light cup + luminous aperture is also unique. Because the light cup depth is shallow, the long-range effect will be weaker, but the flood performance is still very good.
Illumination of the wall: You can see that the X4M center spot is bright and small, while the secondary spot area is large. In the actual illumination, there can be a relatively large flood area around it to ensure that the field of view is wide. It also illuminates distant targets.
Finally, let's take a look at the actual night shooting performance, first open the close shot, you can see the sallow yellow counter that is illuminated in the distance is particularly conspicuous. And all around are also well "patronized".
The effect of paving under different brightnesses is displayed, and the measured X4M does not have any stroboscopic phenomena. When irradiated at high/extreme brightness, the heat of the flashlight is not obvious, and it can be said that it belongs to the "slow heat type" in the used straight cylinder.
The light angle of the flashlight itself is large, and the flood area is also obvious. Excellent paving. Both around and far away can be taken into account. In addition, the SFT40 lamp bead itself is still good in concentrating light, and the obvious light column can be seen when shooting at night.
The range under extreme brightness can reach 238 meters, and the contours and details of the bridge holes on the embankment in the distance can be seen clearly and clearly.
Summary: On the road X4M is a very distinctive flashlight, its barrel length in the 21700 flashlight can be described as controlled to the limit, in both long-lasting battery life and high brightness at the same time, but also can be easy to carry. The three lamp beads can be selected to meet the needs of different user groups, and the addition of the night aperture can also better identify the location of the flashlight. Although the popular magnetic tail cover has been cancelled, it is highly recommended for individuals to start with a comprehensive performance in all aspects.
