Have had my iStick 50 for a little over a month now, and have only EVER charged it with my Dell PC USB port.
No problems what so ever, yet !
I get about 2 days between charging, so Im guessing about 15 or so charging cycles on it so far.
ohms read .1 higher than my other devices most times, but other than that I have no issues thus far....
Hope it remains that way !

It's important to remember a few things.. the coils aren't all guaranteed to be exactly the stated resistance. (we'll use 0.5 ohms, as an example) See, the manufacturer is allowed a tolerance of, say.. +/-0.2 ohms... Unfortunately, what most don't realize, is that their devices are going to ALSO each probably read them differently, too. Reason being, something like the SMOK m80 plus will read all the way to the 100ths place, let us just assume accurately, for the sake of this example. Where as a device like the eLeaf iStick.. only reads to the 10ths place (as do many others) Thing is, however, we don't know if those reading to the 10ths place, are just dropping that 3rd digit completely... OR rounding up, as it would in math readings. Some probably do 1 while the rest, the other.. we just aren't told which, specifically. SO... while keeping that 1st part about the coils & their allowable tolerance in mind... Let's say the coil is boxed/marked as being 0.5 ohms... As manufactured, they may be allowed to be anywhere between 0.3 - 0.7 ohms, & still be perfectly fine, totally within normal limits anywhere in between. That being said, can't tell you how many people I've seen using an iStick 50 where... they are posting, angry... because it won't fire their new Kanger Subtank. Being that it reads/fires down to a minimum of 0.5 which is cutting it incredibly close, as is.. They are wanting to return that iStick or angry about it, immediately writing it off as crap... simply not knowing that coil is probably (again perfectly fine) but could be 0.44 ohms, so as indicated.. no, won't fire... since BELOW the devices 0.5 ohm minimum. Where, on a device reading to the hundredths place & that has a minimum of 0.2, like the SMOK x-cube.. one could see the coil reading 0.44 exactly & firing... nothing wrong with either one. Because SO many are having troubles with 'low atomizer' OR feel their devices are all reading differently... they are. Reading incorrectly, however, no... actually, they are (for the most part) not at all.... esp. once that decimal place thing & coil tolerance...... is understood... or even known. Both coil and device are perfectly fine.... manufacturers really should be clearer about that somewhere tho, cuz people who do know all that are rare AND aren't able to properly fill everyone in. .... as much as I wish we could. =) Hope that helps clear things up AND ease your mind a little bit, at least. IF you do happen to see someone having what they believe to be an 'issue' with a device reading OR a coil not working.. please PIF & pass on that info.. ... LIVE LONG(er) & VAPE ON! -Amanda/IL-
