Major vape mail yesterday. Got my second iStick 30W---my first had to be sent back after one day to evape for exchange due to a malfunction; either the chip was overheating at 10W or the temp sensor was wonky. Haven't received the replacement yet. Yesterday's iStick 30W is from RockyMountainVapor. Four days from ordering to arrival, $31.50 for the full kit with free shipping. I also received the first of two Cloupor Mini 30Ws from gearbest. That one took awhile---five weeks from preorder to my door, but only $29.99 shipped free.
Notwithstanding the recent spate of reports about some faulty Cloupor Minis melting down, my initial reactions to both PVs are positive.
I already had five 20W iSticks, so the new 30-watter brings no major surprises. I like the same things about it that I like about my other iSticks: size, price, ergonomics, and performance. Nice that eLeaf fixed the glaring shortcomings for this version. I don't know all the in's and out's concerning the changes in power management from the slightly rattlesnakey mean-calibrated PWM of the 20W, but the vape seems decidedly smoother on the 30W. My 1.5 ohm EVOD-style clearos that were over-amped even at the lowest setting on the 20W (because of the mean/avg. voltage calibration running hot at low voltages) now seem quite happy at anywhere from 5 to 8 watts on the iStick 30W. Although I intend to use all my iSticks with tanks that like higher wattage, that's good news for lower-voltage vapers. The extra 10 watts of headroom and ability to fire at resistances down to 0.45 ohms make the iStick 30W significantly more versatile.
Obviously, the soft threads and fixed pin of the 20W's 510 connector screamed out to be fixed, and the 30W's redesigned top plate with stainless-steel threads and a spring-loaded floating pin in the 510 connection are a welcome upgrade. The wider lip on the top cap around the 510 connector that allows 22 and 23mm tanks/RDAs to sit flush (with no overhang) will please many users. Aesthetically, I preferred the shape of the original top plate, but I understand why the change was made, and it was probably a smart decision.
The power-selection scrolling on the 20W was a bit awkward with that three-speed nonsense and having to press the opposite button to stop the scroll, and that's been changed on the 30W. Now pressing-and-holding either the up or down power buttons starts moving the wattage up or down by .1 watt with a slow scroll that quickly accelerates to, well, not quite blinding speed, but brisk. Going through the entire power range from 5 to 30 watts takes about five seconds. To stop the scroll, just release the button. Much better.
Other than that, everything else is pretty much the same: basic size and shape, light weight (3.3 ounces), 2200mAh LiPo battery, and the rattling buttons when I do the marimba-shake. Hey, for the $31.50 I paid, it's a no-brainer. JoyeTech and eLeaf should be pleased as punch.
For being so similar in size, the Cloupor Mini 30W is somewhat different. First of all, it's a boxier shape and much heavier (5.5 ounces with a battery installed, versus a mere 3.3 oz. for the lightweight iStick). While the edges are slightly rounded, the Cloupor doesn't feel as comfortable in my hand as the more ergonomically rounded iStick. It's not a bad feeling, just not the hand-in-glove fit of the iStick. The compensation is in the extra weight and case materials. The Cloupor has---how shall I say?---"industrial heft." It feels more solid and sturdy than the iStick. To put it into the ancient terms of smoking, it's like the difference between a Bic disposable lighter and a Zippo. Even if it's just an illusion, the case design and overall weight give the impression of quality. Even a marimba-shake produces only the slightest, nearly-inaudible rattle of the buttons, and the battery door on mine is perfectly aligned and secure (so far). No spring-loaded positive pin on the 510 connection, but the pin is user-adjustable with the tiny phillips screwdriver that's provided (along with a spare pin and three additional contact screws).
The 0.8 second delay in firing when the screen is re-awakening from sleep aggravates the hell out of some people, but for me it's only a minor complaint and not a big deal. I'd prefer instant firing, but I can live with it as is. If the screen has gone blank into sleep mode, I just press and hold the fire button and slow down the beginning of my draw a little.
Since I have a stable of good 18650 IMRs---LG HE2s and Samsung SR25s---I appreciate the Cloupor's user-installed, replaceable battery. Swapping out the 18650 is easy and fast. I don't intend to ever recharge it via USB. Assuming that my Cloupor Mini doesn't blow up, melt down, or catch fire, I'll be a happy camper. Heck, it cost me only $30, even less than the iStick.
In actual use for vaping, the Cloupor Mini 30 and the iStick 30 are effectively identical. Similar layout and button placement, good screens, scrolling ease, same sub-ohm limits, and both perform exactly as they should. Using an Aspire Nautilus Mini 1.8 ohm BVC and an Erlkonigin Nano with a 1.2 ohm cotton-wicked microcoil on both units produces the same satisfying vape at anything from 8 watts all the way up into the 20+ watt range. I've sort of settled in at 12 watts with both tanks.
