The Convoy S21A is a modification that runs on 21700 batteries, which actually have different types of power. In any other case, at first glance, the related fashions are no different from the S2 and S2 +.

In fact, this is exactly what it is, the brand new physics is good and the way the flashlight will usually present itself – extra in the overview.

Convoy S21A: Design and comfort

Familiar physical, completely different dimensions. And in color. This is how Convoy S21A can be described. Besides, there are many variations of the color S21A and one to one black

On the other hand, the flashlight is no worse than the standard 18650 flashlights. Its physical size may be barely large, but the difference is completely illegal.

For comparison, the Conway S2’s scale is 124x24x24 mm, as opposed to the Convoy S21A’s 122.5x26x26 mm. We can say that the compact size compensated for the improved diameter. The qualification button has not been moved. like also Oclean X Pro

Let’s take another look at the lantern and its physical side. The body is a product of plain grade aluminum and anodized. Prime quality coating. You will be able to see in the pictures, the symbol is on the side of the case. It is a great coral framed for a variety of physical elements. It’s great for communication without any flaws.

Convoy S21A: Management and heating

You both have 4 brightness modes, we want to choose from a few extra chips or 12 modes with biscuit UI. Select initially based on your wishes. The price difference between the 4 modes is huge.

Convoy S21A design

Brightness is distributed as follows: 0.1% -3% -30% -100%. I am glad that there is an awning, but the run between 30 and 100% is very large. But this, once again, is not very important. In case of heavy use, 30% brightness will save the battery and provide enough softness.

The driving force here is the same as half of the reverse fashion, and due to this fact the brightness is the same and step by step with uniform settings: when the temperature reaches 55C, the flashlight will robotically reset the brightness to the previous model (e.g., 100% to 30%). This is the place where this step ends and nothing else is needed.

Features of Convoy S21A

The Convoy S21A has a powerful flashlight, which is additionally more efficient than the weird S2, making it impossible to use any unique LEDs (SST 40) and a battery. Like one thing can happen. The truth of all these results is that the S21 heats up enough.

So the ultimate brilliance here certainly won’t be your most important, except it’s a chilly night. In the above, like 55 levels, my thin is warmed for 8 minutes, after which the brightness drops to 30%. At 30%, the flashlight should not be called a kind of smog-sun dim.

Including the 21700, the flashlight’s efficiency almost doubled compared to a daily S2 in 18650 The flashlight has more to say about the flashlight – it has a great degree of water resistance, the flashlight results in two completely shrinkage problems, and no rubber plugs. So you will be able to make sure that the lantern will thrill you after the rain.

Convoy S21A: Being used

Let’s guess the form of the beam. I can say that the beam is not only wide, apparently, but the depth of the reflector also does not strongly recommend it. But the shortstop is plentiful and strong. Taken together, it provides all medium- to long-range flashlights.

The examples presented to make the middle layer the strongest. In life, the sun of the lantern is totally enough to fully illuminate the road to the front and barely to the end.

Convoy S21A: Conclusion

A powerful flashlight on the Convoy S21A. Homeowners of the S2 will certainly appreciate it, for which the sun in their flashlight simply isn’t enough. The power here is just extreme, usually, you want to burn and never burn your fingers from your heat or decide in any brightness mode so decide not to warm the case with as much imperfect temperature.
