Koopor Plus 200W
Quite frankly if you buy this, you are investing is some good packaging. That's about it – after that frustrations take over.
The Koopor Plus 200W marketing and packaging seems to be the focus of the company. It certainly isn't focused on quality control or decent device design.
We were sent the black unit to review. Included separate from the packaging is a plastic bag marked as "gift". The gift is a silicone skin.
The silicone skin is also poorly designed. It is a nice thick silicone and will last some time, but this device is not chargeable through the USB port on the bottom of the unit. You'll have to remove the skin every time you need to charge the batteries – and that is quite frequent. At the top of the silicone skin is a section that slip over the top of the Koopor Plus 200W. That portion is quite long and makes it difficult to remove the silicone skin and put it back on. To be more "user friendly", we trimmed that portion with a pair of scissors to about 1/4 inch (removing about half of that portion of silicone material). Easier to remove and put back on. That should have been checked and done at the factory, though.
Colors available include Red, Black, Stainless and Matt White. The finish also includes an electronic circuit design on the outer cover below the Koopor logo. The opposing cover has the "Plus" product logo – and an extensive array of small vent holes. 110 of them to be exact. The inside of the device is clean and showed no build artifacts. The inner plastic shroud also has an extensive number of vent holes and four reasonably sized magnets.
I also noticed the battery retainer springs appear gold plated.
The batteries are connected in series with a maximum of 8 volt output.
The material used for the box is stainless steel and a zinc allow. It's a beefy weight at 274 g.
The battery cover is the sloppiest fit I have ever seen. There is a good 1.6 mm side to side movement when it is in place. It's frustrating, noisy, and even the silicone skin doesn't mute the noise enough. Even through the silicone skin you can feel the cover moving around as you squeeze a bit (every time you press the fire button).
For the next "frustration" refer to the picture at the left.
The OLED screen is a reasonable size, and high contrast. It's visible in most lighting conditions except direct sunlight.
Above the OLED display is the fire buttons. Koopor is working hard at redefining how we vape, though. The fire button is now multi-function. After inserting freshly charged batteries, five on/off powers on the device. Five more on/off is to lock the device. In locked more, five more on/off is to power off.
Now the "frustration". The buttons below the OLED display are reversed.
The Up button actually reduces the wattage (in wattage mode) or temperature (in temperature control mode).
The Down button actually increasesthe wattage (in wattage mode) or temperature (in temperature control mode).
As shown in the picture, it is reversed. According to the user instructions as well, it is reversed functionality.
For example, in their instructions, Koopor says that to toggle Stealth function, you press the fire button (KOOPOR button) and the UP button. That works, except the pressing the UP button by itself to adjust wattage/temperature REDUCES.
Also note the graphical battery display. You'll see like that quite a bit. The Koopor Plus 200W is a battery hog. Barely able to get 5 ml vaped from a NEW freshly charged 2600 mAh batteries.
The screen rotation shown in Koopor's marketing pictures is not the default. So, next frustration: try to go through the settings menu. That's three rapid succession clicks of the fire button. Go ahead ... you'll need the instruction sheet with you to navigate. There's also no action button, so you have to select what you want and wait for the device to go into that setting mode for you to make changes.
Koopor includes a "gift" with each purchase. It's a nice thick silicone skin. Quite a bit thicker than most silicone skins and should last a long time.
It's fairly useless though. The first problem is that the Koopor Plus 200W does not charge through the USB port at the bottom. That's reserved for firmware upgrades. And this device is a battery hog (as noted above). I was barely able to vape more than 5 ml of juice from a fresh set of brand new 2600 mAh batteries.
Note sure if that is due to Koopor's touted "dual driver system" and "high-frequency dynamic monitoring resistance". It is annoying having to slip off this poor fitting silicone skin all the time to recharge.
The skin design is not that great. It is tight fitting. As you can see at the upper left, there is a section of the silicone skin that slips over the top of the unit to help keep the skin in place. From the edge of the unit, that portion is at least 1/2 inch. Trying to manipulate that over the side of the unit helps create drag and renders the exercise of removing or replacing the skin into a exercise in futility. Sure, you'll get it on and off, but the fight isn't worth it several times a day to recharge batteries.
To Koopor's credit, the silicone skin holes in the side are fairly good at matching up with the vent holes in the magnetic cover. The bottom silicone skin holes also are fairly good at matching up with the bottom vent holes.
If you can get past the frustrations of using this device, the vape experience is good. Power transfer to the coil is instantaneous. Koopor did a good job of also adding Min, Normal, Hard and Max vaping effects. I've used this on other devices and it is an excellent feature. Not sure exactly how it works, but I suspect it is the intensity of power initially transferred to the coil and can enhance the vape experience considerably. On the Koopor Plus 200W, I keep it on "NORM" and find it quite pleasurable to vape and get a perfect vape from the get-go, all the way through the inhale.
The 510 connector at the top is spring loaded and I had absolutely no problems with any tank I tried this with. The top of the 510 connector has four generous air flow holes for bottom air feed tanks, but it is fairly small. The top is also raised from the top of the device, you will get a small gap between the tank and the top of the Koopor Plus 200W.
I liked the springs in the battery compartment. They are firm, but a lot easier to get batteries into the compartment than the tab style.
So, what’s the verdict? Is it worth it?
You'll have to judge for yourself. My recommendation is to pass on this device. While the price is reasonable, the value is not anywhere near the price. The electronics and circuitry are fairly good, but the build quality and materials are sub-standard. Quality control is horrible. The device we were sent for testing and review has a poorly fitting magnetic cover with a wide side to side slip, but it also had "scratches" just above the firing button. When we inspected the scratches more closely, it turned out to be glue residue that we were able to remove. Obviously, the inspection process before these things are boxed isn't up to par. We are not going to put any contact or pricing information with this review.
