Encom TX 70W
This heavy beast (415g) is available in three colors: gray, green, light blue (as shown at right).
It is in three parts: the core unit (the color part), a brushed stainless battery tube (shaped), and a knurled battery cap.
The company claims this as a "revolutionary TOP style 510 spring loaded contact pin" ... I could not detect anything revolutionary about it other than the pin is smaller than usual and appears gold plated. There are various pictures of the top portion floating around the internet, most are not the same as the shipped unit. The top is solid, gold plated, and the 510 connector appears isolated and floating with a smaller protruding contact portion. The smaller contact point is a desired feature, by the way. It will prevent shorts in clearomizers that have a large 510 connector pin.
We received the gray unit for testing (shown above). The Encom TX 70W is heavy, one of the heaviest we have handled in recent memory. The top firing button has no rattles whatsoever, but – sad to say – the bottom adjustment buttons rattle quite a bit (when shaken). The OLED display is very nice and bright with high contrast. It's easy to read in almost any lighting condition and one of the best we've seen.
The unit is form fitting to the finger folds. About the only practical way of pressing the firing button is with your thumb ... and that's not quite what I expected. If you hold this device to fire with your index finger, the adjustment buttons can easily be pressed with your small fingers. If you hold this device to fire with your thumb, the adjustment buttons do not come into contact with your hand inadvertently (the edge of the unit would sit on the lower portion below your thumb).
This device uses one 18650 battery that is not included in the box. We used it with two different batteries: a Samsung 25R 30A 18650, and an Efest 35A 18650 battery. The only reason for trying it with two batteries is that we thought something was wrong with the original (Samsung 25R) ... we couldn't vape in temperature control mode through one single tank of E-Liquid before needing a recharge. Regardless of the mAh capacity of the battery, the Encom TX 70W goes through batteries unusually fast. The OLED display also does not accurately display the remaining charge of the battery ... we ended up with "Check Battery" (and no further firing) when the display was still showing 50% capacity. (Note, this is in Temperature Control mode). We also noted that it did not work well in Temperature Control mode, reporting the coil resistance incorrectly on two different tank systems with an inconsistent vape experience. Inhaling with smaller intervals between inhales reduces the effectiveless of power transmission to the coil.
In wattage mode, it's a different story. The Encom TX 70W displayed the coil resistance accurately, and delivered accurately on the wattage selected. The experience was identical to the most accurate device we have on hand and consistent.
The Encom TX 70W is not the faint-hearted. The OLED display shows temperature and wattage simultaneously. There is no way of shutting down temperature control mode to use wattage only ... and no way of shutting down wattage mode to use temperature control – both display at the same time. Other than your memory of what the last setting you changed, there is no clear distinction between the two. When you adjust the temperature, you are in temperature control mode. When you adjust wattage, you are in wattage mode. Disconcerning at the very least if you have more than one mod on the go at any one time.
In wattage mode, the Encom TX 70W is more judicious in battery consumption.
Overall, I like how it feels in the hand. It's unobtrusive with the OLED display facing the palm of your hand ... a momentary tilt of your hand and you can see a very bright high contrast screen with information you need. It's slim at only slightly more than 22 mm thick. Any 22 mm tank looks like it just belongs there, particularly with the gray unit. Width is just as convenient a fit in the hand at only 50 mm ... and it's form fitting so that it feels even more comfortable in the hand. With the 18650 battery tube facing your fingers, it's quite comfortable to hold. You will have to get used to using your thumb to fire the device, though. That didn't take me long at all.
The unit comes apart quite easily for cleaning and maintenance. The tube that houses the 18650 is reversible, that is the threading is the same at the top as it is at the bottom. Threading is fairly smooth and I had absolutely no problems putting it on or taking it off. You'll have to hold the tube and unit with one hand while removing the battery cap, though. Unless you hold the tube with the unit, trying to remove the battery cap will loosen the tube as well. The battery cap is similar in concept to a mechanical mod. The spring is inside a gold plated housing. Both the top of the unit and bottom cap have adjustable Philips-head screws to accommodate button style batteries and flat style batteries. Venting is through the bottom battery cap with a total of 8 holes. And, the battery cap is flush with the bottom of the Encom TX 70W when threaded in place.
The battery is inserted with the + anode facing the top (towards the 510 connector) and there is reverse battery protection along with the other usual safety protectors.
Overall, the only negatives are a poorly written Chenglish user manual on one single rolled up sheet of paper and Temperature Control mode that doesn't work well.
So, what’s the verdict? Is it worth it?
You'll have to be the judge on this. I like it. I like the weight of this heavier unit. I like the rounded and form fitting shape of the battery tube. I like the unusual position of the firing button on an angle at the top of the unit – it really sets the Encom TX 70W apart from other me-too devices. I like the gray color and how well it suits the chrome and gold-plated parts. I like it for wattage mode and will use it exclusively in wattage mode. I don't like the user interface and would prefer to have some more distinct way of telling if it is in wattage mode or temperature control mode. And, I absolutely hate its battery use in temperature control mode. Would I buy a second unit? Maybe, I'll need more time with this to determine that.
