I saw this thing for the 1st time about 5 hours ago, it has to be the ugliest mod ive ever seen, and ive seen plenty of Vapresso mods...
I once owned an SX Mini, happy to part with it after i found it was the most fiddly TC device ive ever had, too many things to set to get tc working properly. I miss its heft though! Then i got a DNA200 device. but that still wasnt as easy as my TreeBox...no atty lock (i do not miss holding down the up&down buttons every time i changed locations - even in the same damn house), no room temp settings, no joules malarkey, and no rattlesnaking!. Just set the wire/coil type and temp and press the fire button. I have a few of the things, best mod i ever bought. 1/5 the price of the SX and 1/2 the price of the DNA200. The DNA75C though is calling to me....most of the functions are now on the device, no need to tether to EScribe.
But the G Class is ugly as sin, sorry. And unless theyve changed the amount of thigns you have to fiddle with to get TC working i wont be SX'ing it anytime soon. Easily the most overrated chipset out there. A friend who shall remain nameless says his only gripe with it is the green menu system
I've never used the device you speak of. What yihi has done is drastically improved batter life over previous models. The ui is wonky, not intuitive at all. Getting it connected to a PC or your phone is wonky. There really isn't alot of settings you need to configure, its getting the settings you would need to configure on ANY device setup that is frustrating. Turning Tc on, setting Jules to your preferred number, setting your temp, and setting your could type with its tcr setting. What is missing is battery profiles but hey. Everything else is eye candy as far as the device is concerned.
Maybe ramp up time might be important but in my mind, ramp up curves aren't setup correctly on any device. Ramp curves should be percentage based depending on the current temp of your coil. That is, I don't need a ramp up if I take 3 hits back to back except the first hit. If I wait 30 seconds between hits the ramp up should be a certain percentage, not the full ramp up. In other words, if my coils are cold, give me full ramp up. If they are warm, do a partial ramp up. If they are already hot, don't do a ramp up.
Cheaper devices, in my experience are hindered by their efficiency. That is, I need twice as many batteries for the same battery life of a more expensive controller.
Which by the way, let's talk about lingo. The "board" or "chipset" are the wrong terms. It is in electronics terms, a controller or a controller board.
Speaking to charging on device, I haven't tested yihi charging. I have tested evolv charging. Evolv does it correctly,provided you have your battery profile loaded correctly. Perhaps back in the day, charging on device was bad. However, I don't know why this myth continues to propagate that one should not charge on device, especially with evolv boards. When we are talking about the amount of amps dumped into the batteries, 2 amps split between 2 batteries at an amp a piece is perfectly acceptable. These batteries are rated at 300 charge cycles, which, I won't get into how that works here. Charge cycle does not mean what many think it means. I encourage you to ask Google and research this.
These batteries should be good for a year or two at a 1 amp charge. Putting half an amp versus a full amp into the batteries will not noticeably alter their lifespan. Plus, battery technology is improving every year. I replace mine every time I buy a new device, or yearly (ironically, I replace my device about once a year and I use 2,one at home, one when I'm out). When we first started using 18650s,they were 1100 mah. We are at 2500-3000. I'm even starting to see name brand 3500 mahs come out. Seriously think about how often you realistically change your batteries with new ones because when you do, I think you'll come to the same conclusion I did, I just don't care. If charging at 1 amp reduces their lifespan by a month, I'm not worried about it.
The safety on the other hand is a valid concern. Balanced charging is not as important as people make it out to be in my opinion, tho, the device should be smart for the people who aren't. If you just use the same batteries in the same device and keep them married, there is nothing to worry about.
