Overview: Cloupor T8 from Canvape
A few disclaimers to start with: this is NOT a review. We are not testing this device for output voltage or wattage. There is a significant risk in using multi-battery systems. If you consider using one of these devices, you have to be aware that you are taking high risks, putting high voltage to a coil that is near your face and pointed directly at your throat. We do not recommending using these devices at extremes of low or high wattage.
The Cloupor T8 is the third multi-battery system that we have used. All were pre-ordered many months ago and all are production units. The Cloupor T8 is the smallest of them all and has the best finish and build quality of all three. This is also the last multi-battery system that we had on pre-order and we do not plan on any reviews (or overviews, articles, etc.) of multi-battery systems.
The Cloupor T8 is available in four colors as shown at the left. Red, Black, Silver, and Blue. The unit we received is the black one as shown at the right.
The functionality of the buttons and OLED is identical to the previously reviewed Cloupor T6. The buttons are identical, the 510 connector is identical.
The back cover is nearly identical and it has the same familiar dimples. The only difference is that you have to lift off the back cover on the T8 and on the T6 it slides off. The major difference between the two is that the T6 has pass through charging through the USB port at the bottom and the T8 USB is strictly for software connectivity for future upgrades. To charge the batteries in the T8 you have to remove them from the unit and use a dedicated charger.
Here's the specifications for the Cloupor T8:
- Output power: 7W-150W
- Dual 18650 battery
- Convenient magnetic back cover
- Adjustable 510 Pin
- Output voltage: 1.5 volts to 7.6 volts
- Max output current: 20 Amps
- Resistance Range: 0.15 ohms to 4.0 ohms
- Internal Circuit board with self heat dissipation
- Reverse battery protection
- CPU temperature control system
- Instead of screen lock, unit can be turned off
- Color: Black, Blue, Red, Silver
- Can not be charged through USB port, USB port is used strictly for upgrading firmware in the future.
Included in the box is a mini screwdriver, retractable micro USB cable, spares, VIP authenticity card and a user instruction guide.
The only device similar is the IPV 3, also with batteries connected in series. We have withdrawn the review of the IPV 3, but the specifications are still viewable. The Cloupor T8 is narrower by 4 mm, shorter by 3 mm and slightly thicker by 1.7 mm. Overall, it is slightly easier to hold. Weight is nearly identical for both.
The 510 connector on the Cloupor is a brass color and adjustable with a philips head screw driver. There is a "well" around the connector to aid with air flow.
Inside, the unit is very professionally done. All of the connections are brass colored and the battery compression springs form a positive connection and firm. There are no visible artifacts from the assembly process – it is a very nicely designed and built device.
I chose two Efest 3100 mAh batteries for this peek at the Cloupor T8. Both are rated at 20 amps, the maximum that the Cloupor T8 can make use of. The back of the unit, by the way, has the same type of dimples as the T6 and as you can see from the image above, it is retained by rare earth magnets. They are marked and can only go in one way – the magnets will repulse if the cover is inverted. The cover can be removed by using a finger nail into a small slot at the bottom of the unit and prying it off. While the magnets do an excellent job of retaining the cover, it is fairly easy to remove the cover when you need to recharge the batteries.
On the opposing side of the buttons, the Cloupor has twelve vent holes at near the top edge, and twelve vent holes near the bottom edge. There are also six vent holes at the bottom.
Adjusting the wattage works similar to the T6. You can adjust in 0.1 watt increments from 7.0 watts to 100 watts. From 100 watts and up, the changes are in 1.0 watt increments. As you hold the plus or minus adjustment buttons, the speed of change increases. It still takes a fair amount of time to get from 7.0 to 150 watts though, and vice-versa. Fortunately, adjustments tend to be within a much smaller range for daily use and quite rapid. You can also lock your selection by pressing and holding the + and - buttons for a few seconds. I set mine at 8.0 watts and locked it in place. At 8.0 watts on the Cloupor T8, I get the same effect as 8.5 watts on other devices.
Cloupor has built in protection on the Cloupor T8. First, there is heat dissipation built into the circuit board. That means that as heat builds up inside the unit, the circuit board gets rid of that heat to remain operating at optimal temperatures. There is also CPU (the chipset) temperature control. In the event the CPU overheats from a malfunction or extreme use, the device will shut down.
All of this being said, I need to point out that I had not planned on writing this article with an overview of the Cloupor T8. Shortly after pre-ordering the Cloupor T8, Cloupor announced that the maximum output voltage was going to be 14 volts. With that specification, I wouldn't even have opened the box. The production unit, though, has a step-down converter (aka buck converter) that limits the voltage to 7.6 volts. For my personal needs, that is an acceptable range – still with risks, but minimized – in my opinion. If you are considering using a Cloupor T8, you need to look at the specifications closely, the batteries that you will be using, the atomizer you will be using, and the coils you will be building/using ... and then decide if the risks are acceptable to you.
So, what's the verdict? Is it worth it? Clearly, no – this is not a device for anyone that does not have intimate knowledge of technology and the risks associated. The advantages of having multiple batteries for the average vaper are strictly in use time between charges. In this regard, all multi-battery systems will deliver extended vaping time. But the ranges of output power are too extreme and put these devices in a risk category that is awfully hard to ignore. Use at your own risk. If you are considering using a mechanical device with multiple batteries, the Cloupor T8 is a much much safer alternative and you at least get protection from the step-down converter limiting voltage to the coil.
