Reviewer comments on business characteristics

E-Square is a high-end box of Chinese manufacture. Lost Vape chose the famous DNA 40 gold v5 from Evolv to animate his box. Its price places it in the average of the tariffs noted for this kind of product. I want to say again a box wanting high-end, still the DNA 40, this box brings other than a different design?

Reviewer's comments on physical characteristics and perceived quality

The E-Square is inspired by the design of the "ticket box". A simple, rectangular shape with rounded corners, the large OLED screen on the front, and 3 round metal buttons.
First thing, it is light, 110 g for a double box battery is light, maybe even a little too much which gives a misleading impression of fragility. Second point it is compact, although I admit that the shape close to the square is unusual so a little destabilizing at the level of apprehension as I am used to more elongated or rounder forms.
At first I will say nothing extraordinary, the design is very basic and I did not immediately realize the quality of the materials used, probably because of the color black. But a mechanic friend in his spare time, he immediately told me: "wow! It is beautiful this carbon and aluminum frame is aeronautics ".

Well yes 6061 aluminum is a strong alloy used in the manufacture of aircraft parts and carbon is indeed very good. Anodizing is also of good quality.
The buttons are very responsive and are perfectly adjusted.
The 510 connection spring seems solid and ensures the "flushitude".
The access panel to the batteries slides perfectly and once in place it is difficult to distinguish as it is well adjusted. The housing that hosts them is very clean, but I find that the batteries are a little cramped so to remove the flat screwdriver to lever is essential.

The micro USB socket is at the bottom of the slot that houses the controls. The OLED screen is the traditional Evolv screen.
In summary, a beautiful quality of workmanship, beautiful materials, a box that will particularly affect fans of mechanics.

Reviewer's comments on functional features

What to say, we all know the DNA 40 that this box embarks. So E-Square has all the functions that are usually found on this chipset.
A variable Wattage mode that offers you the ability to modulate power on a scale from 1 to 40 watts, with a resistance value between 0,15 and 3 ohm.
A TC mode with an adjustment range from 100 ° to 315 ° Celsius and accepting a resistance value between 0,1 and 1 ohm.
You will be able to lock the resistance value when you use the temperature control for better vape stability.

E-square screen 0
The highly readable display shows the battery charge, resistance value, watts and temperature when using the CT.
At the protection level no major concerns, apart from the polarity reversal can be. I saw on Facebook the misadventure of a user who has suffered an instant degassing following the reverse insertion of his batteries. A priori the electronics is not in question since it went back to work after the incident, but it would come from the cradle, now I take this info conditional since I will not try to reproduce that with the model of ready.

Reviewer's comments on conditioning

This precious box will be provided in a transparent plastic box, simple but correct. This box reveals the appearance of the material immediately. Inside, your box of course, a USB cable winder (that's cool), and the instructions. As usual, you will need help from your English dictionary if, like me, your level of use of this language is about as high as that of the sea. This is a recurring problem. all the more incomprehensible that according to some statistics the French market is the largest in Europe.

Reviewer's comments on the use of the product

E-Square is currently one of the most compact regulated 18650 dual box on the market. So it will be a good companion for those who can not recharge during the day, because the DNA40 coupled to two batteries offers a very comfortable autonomy.
No need to tell you that the quality of vape is clearly at the rendezvous, but you already know it if you had the chance to test this chipset; for others I will tell you that for me the vape on this chipset is a fullness, perfectly regulated and that even if 40 watts is little in front of some competing boxes, the quality of vape of the Evolv is still very impressive.
The only shadow on the board comes from the difficulty in extracting the batteries as they are cramped in the cradle. A small ribbon would have been good to solve this problem.

The mood ticket of the reviewer

The E-Square of Lost Vape DNA 40, another high-end box that ships this chipset, which demonstrates a certain supremacy of Evolv on this sector of the range.
The E-Square arrives with a look very close to the famous Ticket Box, a rectangle that pulls on the square, sleek, basic. The aluminum that makes up the frame comes straight from the aeronautics, lightweight, solid is very resistant to oxidation. At first glance, the beautiful seems thin and not very solid, but after a few minutes of hesitation (or as soon as a wise buddy does not blow you, after having had it for a second in the hand) you will become aware of the quality of carbon veneers, and then you will realize that the aluminum frame is not ordinary.
At that time it's fascinating, this box that I found not very ergonomic (because I thought it fragile I was crisp on it for fear that I do not escape), a bit mundane in design, bland limit. I started to consider it differently. Indeed, if we look at it carefully, these clean forms, its quality of adjustment are only used to highlight the quality of materials and coatings. It is very successful.
Its dual battery cradle gives you a very good autonomy, associated with the good tank you hold there, the machine for the long haul.
The electronics are more present, it is one of the "must have" of the moment despite the small 40 watts displayed.
In addition, a large number of colors are available on the market, hard not to find one to his liking.
Note also that for those who would like smaller, it exists in simple accu, which gives it very suitable proportions.
In short, a nice meeting and a little surprise, because frankly I was not super excited to see it on my list, it was really not the kind of box in which I put 179 euros. Not fan of this style that evokes for me the world of tuning, when in fact it's not tuning. No it's more beautiful sports, made with beautiful materials, and very well finished. Sports to the end, your batteries will be so well set in their molded plastic cradles, you will need more than a fingernail to allow you to extract them.

WARNING: Be careful to put the batteries in the right direction. The box does not have protection against reverse polarity so there is a proven risk. Risk that does not exist if you put the batteries as indicated.

Thanks to the Little Vapoteur
