    Are you crazy? No more stuff to discuss here?? Are there actually no more problems with our 'old' hopper to solve that you seriously suggest to develope a new device by GHL??

    NO! GHL should only focus on construction of the Hopper until all Hoppers are working flawlessly and reliably over years!! Period.

    Its only allowed to them to optimize the Hopper aside developing of the long announced ss case - WTF is so difficult on this?? - and their long announced concentrate insert!

    All fine but step by step...:2c:

    Where have you seen enough cases? I'm just curious, as i've only read about one, and that ended up being a defective Nitecore i series charger that was overcharging to 4.25v. He ended up burning through batteries like crazy, understandable.

    I put alot of time into this yesterday, and although I self confess to having extremely limited battery knowledge, the overwhelming majority of what i've read points to the Nitecore being a more than suitable charger, in fact even 'the best'. This is just what i've read( google: grasshopper + nitecore), and even IF my batteries don't last as long as using the OEM usb charger (theory), at this point I don't even care.... because it would be ruining my enjoyment of the GH. We can discuss this all day long....i'll ask GH about it today, and hopefully put it all to rest.

    The Nitecore d4 does this perfectly in my experience.....they finish charging at 4.20v, and then stop. When I put them on they are usually around 3.8v-3.9v.

    Really hoping my GH's are shipped back out of the lab today....they've had them the entire week. How long does it usually take? I thought a few days...

    The D4 will charge 2 batteries at 375mA if you put them in seperate rails, ie. One in the left 2 bays and one on the right 2 bays. As the first 2 bays run off one rail and the last 2 of another.
    I have 2 D4 chargers on hand and even though both units say 4.20V when completely charged a test on the multimeter says 4.15V. That goes for any Li-ion battery charged from it.
    Charging the batteries with the OEM charger from GHL truly charges to 4.20V.
    Plus the GHL charger software is optimized for only that specific battery. The D4 is programed to handle a "range" of batteries not just one type of custom made battery.

    Torch and e-cig forums I was reading and just from googling model numbers

    Look for the most part, Nitecore is a good brand.
    I'm bashing them too much.
    All I should be saying is there are better options, and it makes technical sense to use them.
    I've tried to learn and describe just why that is the case, and it seems pretty clearly worthwhile

    There are absolutely worse options though

    I would like to use pure concentrates too , but I think you must charge it every time , or every two. With e-liquid you can stay out for two weeks without doing anything...I got the Joyetech dual , and in dual mode also the two batteries lasts two weeks ( 14/16 hits pro day ). If it would be legal also where I live , I'd prefer my GH in my pocket , with some flowers and two or three batteries and that would be the best. Anyway e-liquid is very confortable.

    Hi guys,

    I had a mishap and managed to damage to batt wrap a bit (a scratch nearby positive terminal.. The external chargers contact snapped and kinda cut into it... Fuck). Knowing it's dangerous as fuck to use it, I put it away for now unless I find some fitting shrink wrap to rewrap it. Has anyone found a suitable product? Only finding 18650 ones.... Any help is greatly appreciated! (Buying new batts is NOT a fix for my prob, so please don't suggest that :p)

    Thanks for your tips! :)

    Try electrical tape if it's not too bad.

    Otherwise, the hopper cell size is 12630. 14650 wraps might shrink to fit.
    I've heard a lot of people recommend it, but never anyone try it.


    Incidentally and on another note;
    I just unpacked an Xtar MC1 I got for a friend.
    It's a great size! Extremely portable
    And just to add to confusion, it's worth noting that the MC1plus is no good for GHBs, the older MC1 is perfect

    Wow, that was even faster than a GH heat up... Thanks man.
    I'm not sure how it's easily doable with electrical tape to cover the whole body seamlessly..
    "Double taping" would make it too fat.. I tried some thin snippet of scotch tape, that doesn't do the job. Too fat.
    So I think I need to unwrapp it completely.
    I don't wanna risk anything and am not a pro when it comes to these things.. I would think just a tiny uncovered gap somewhere along the body would be still pretty hazardous. So I gotta find a proper solution prior to unwrapping that damaged cell.

    Will check those 14650s out. Hope I can find them somewhere over here.
    Thanks again for your response, mate! :wave:

    If anyone else has fitting solution, I'm all ears.
    Thanks!

    that's what she said :tup:


    How bad is the tear, as long as there isn't metal/metal contact with the hopper it will be fine.

    But best not to risk a short

    For what it's worth....

    Vaporizer Wizard on FC said: "I have use X1 AC Plus plenty of times to charge, however it was with this 3d printed battery holder. Matt told me never to charge faster than 2 amps, but I still usually charge at 1amp if I have the time just, hopefully that will keep the batteries lasting a little bit longer."

    EDIT: OMG have any of you read the comments on the GH on the vape critic's site? lol

    gees that would be fast charging at 2000mA, I guess 23 minutes.

    The difference between 2 to 1 is twice the difference between 1 to 0.5, but the same amount proportionally.
    I guess also, a reviewer doesn't really have to worry about long term charge cycles when he's releasing a review 6 months before there's an issue either.
    Though FWIW HL don't endorse or promote reviews in anyway (which is why they're all quite honest, compared to the rest of the general selection)

    If you have to pay someone to convince me your product is good, it is 100% a bad product

    That's why forums are great (and why I am so appreciative of what @BuzzDanklin offers), I own so much amazing quality shit because of forums and dedicated reviewers, and I like passing on the favour when I can. With the GH, with Xtar.

    I've killed batteries with 1A charging, it took 7 months.

    My friend, who owns batteries the same age as 2 of my dead batteries, still has his all going strong. He only charges with the HL charger, and I've just now received an Xtar MC1 to give him, as it matches precisely the charge specs the hopper OEM offers (or at least the charger spec Trevor recommended pre OEM charger days [which as a US mains device, is useless to me here in Australia. My old charger (unsuitable) was only working on one slot, and eventually stopped working all together. After reading up on what my best option was, a reputable source lead to the Xtar MC2.

    Measured off the charger, Xtar are very precise. And the discharge rate and charge processing is industry leading


    EDIT: forget all this battery charging talk. Sorry for being obsessed with my portable lifeline :p

    What are the Vapecritic comments saying? Haven't read them since the big event itself >< :p
    The comments here were quite interesting too.

    A steamy topic

    Is this why @Zenpen was banned here? :lol:

    I'll leave the vape critic comments for you to read for yourself, but there is a very unhappy angry cohort out there that's forsure. Understandable based on the reasons I have read why.

    As for the batteries.... fortunately they are fairly affordable, but I honestly personally think that the heat from the device (especially with the hot back end issues) probably destroys the cell more than any charger IMHO.

    I tried to do the best thing with a wrap , bought it from an electrical shop , cut it , heat with hairdryer and the work was perfect ! I was very proud of myself until I tried to put the battery in the Grasshopper ... no way , it was too thick ! It's incredible to say , because the wrap was very very thin and all in one with the battery , I did'nt believe. So I tryed another time with a "simple" electrical tape , but a 50 mm. one ( 5 cm ). Done a very good bricolage work, cut exactly the diameter and put it on the batteries. Also this has been a very good professional looking at the end , and it works , it works great and i think there's no way to get a short. The electrical tape is also "flexible" , more than the original . I usually charge batteries on an Xtar VC4 , and when you take them out , if you don't pay attention , you can demage batteries ( I did so with all mine). Sorry if I don't post photo , I don't want to get risks , here where I live people are strange...

    did you read my spiel explaining the ZenPen situation earlier?

    It kind of is, but it was mainly because of irate people here.
    And they left of their own accord, after some stupid bullshit they were able to continue posting, and they did for a short while.


    Okay, no link guy, I shall surf to unknown sand bars for the lolz

    I've never taken out a hot battery from the hopper, and I've tried to.

    Even with the over heat lights, it's just casually warm in there.

    ...

    "Ah yes, the Grasshopper vaporizer. the elusive portable vape pen for dry herb."

    Look, I'm not finding much funny as hoping.

    It just seems like a consumer shit storm in there.

    If they had half a researchers brain on their shoulders there'd nearly be no comments (or a website.. too far?).

    I did, that's why I brought it up again...just kind of a joke, but I was misconstrued I thought they were banned for shilling, not run out of here.

    All you bro, just scroll down to the most recent and work backwards.... some pretty funny posts, recent ones, the older ones are just whining from long delays, etc.

    One of my personal favourites:

    "Wow…GH Labs have done something that most companies find very difficult to impossible; they have destroyed their reputation and customer good will before even shipping the product.

    Outstanding."

    Maybe my sense of humour is different, but it give me a pretty good chuckle!

    Yeah casually warm is the better term, I usually throw them on the d4 even when warm. I know I know, risktaker and all...

    ---------
    The comments are customers, why do they need half a researcher's brain? Maybe they aren't beneficial to you, but I appreciate all comments from consumers whether they are positive or negative, I just wanna hear their experiences.

    If you are slamming Vape Critic, that's another storey.... he was absolutely destroyed after reviewing the EVO so harshly the first go around (for just reason) but IMO is a very legit and credible resource. I may not agree with all his opinions, but I think he has more than half a researcher's brain.

    Apologies for leaving out the link, forgot to "paste"! Thanks for doing it..

    Cool, well I probably didn't make good sense of it before. But yeah, they were banned, and they were like 'sorry guys, honest mistake' (which was not even really a mistake, I mean, a thread bump isn't the biggest evil out there now google changed their ways) and everyone here was like "you guys are faking it, full of lies, deceiving people" "you're product is bogus" "none of these are actual quotes but we think you are the worst HL!!"

    Then the admins went all CSI:FC and HLs mundane story of the younger brother on a separate computer on the same network posting to the thread checked out.
    But there was still no chill.

    And all during this HL was struggling big time to actually realise their product.
    Even today the struggle is real, because no one has any patience these days.
    As is evident from the Vapecritic website..

    No worries brah, I got this.

    All these complaints man, like yeah you're spending money, but not Mighty level money.
    So do you really have a right to complain when you receive what some consider more value?
    Would you buy a Porsche and complain that it's not a 1997 flawless Toyota Camry at the first service interval?

    HL were chased out of here because everyone expected them to be lying about an assumed impossibility, and now HL have established themselves although are still having occasional batch issues.... lets raise hell bitch. Their impossible product is not impossible enough!

    This one made me chuckle

    "No doubt dude. Fuck GH labs and their shady ass business techniques. Just be up front with customers and tell them you suck and have no clue how to estimate a shipping date and they would get a lot better respect from me. I waited 7 months then got my cash back.

    Firefly 2 it is"

    r3sp3c7 hard work you little shit, if I had a lawn, I'd tell you to get off it

    Also, no one gives a fuck about your bloody respect when you are literally throwing money at them....
    You have straight up given all they care about from you away
    Future hopperers thank you for your place in line whilst you opt for a completely different device

    Thanks mate. Do you think you could provide a link to that particular electrical tape?

    Damn.. I'm not the only one... I too have the VC4. And I guess I experienced the same like you. When trying to get the batt out it spun and got flipped out... The charger is great - but the springs are pretty strong... So be careful whenever you try to get your GH batts out. They're tiny and not too good to grab.


    Thanks for your help!

    EDIT: OMG have any of you read the comments on the GH on the vape critic's site? lol[/QUOTE]

    I have watched his hopper review and read the comments on the vid and his site. It made me realize what a donk the vapecritic is.. He's just shook because he's not able to get any supply to sell and he knows it's the best vape in the game. He doesn't even attempt to use it without water in the video to display it's awesomo powah. He just claims it's too hot for his pretty lips. All other vapes get a visual display.. Same thing with Toronto vape's "review" of the hopper, those clowns didn't even get a unit to review.. Unfortunately all of the vape "reviewers" are pretty craptastic and offer little to no review of the products. It's more of a demonstration and then a link to buy.. thanks for nottin.

    It's a big game to the retailers and they wanna push chinese shills-nit all over you. They don't actually care about which vape is the best, they just want the largest markup possible on the products they sell to you. And that's why we have this wonderful forum to decipher all their shills-nit and bring the power back to the people who care :rockon:

    Thanks @lazylathe for the link, but we are ALL still waiting for your GH experiences from last night :brow:

    ------

    Noticed that it states that the GH is 100% convection. How is that possible when I see vapour come out of the intake holes just before it turns blue?

    Nah, I haven't charged it since last Friday and I have pretty much the tiniest mod on the market. Also keep in mind you'll need more hits than me because your concentrate is weaker (diluted with e juice), so you probably use as much, if not more battery power that way.

    yeah 100% convection is a strange claim.
    On demand heating is as confusing though, for the same reason.

    There'd be a tiny amount of conduction, but it would be a lower temp than the air, but a faster transfer.

    You must have some dank to be noticing that though..!

    I think there's always going to be some conduction in convection vaporizers where the herb sits.

    All my medicine is dank...mostly nearing 30% THC. I notice that about a second before it goes blue, I see a small wisp of vapour exist the intake holes. I have personally always felt that the GH was not 100% convection, just based on its behaviour and the resultant ABV. If you want true convection, the MiniVAP is waaay more of a convective experience. I think the GH has a shit tonne of radiant heating, especially once it gets going, which can make the ABV look darker than a true convection vape like the MV. But I could be wrong, and probably am, but this is what I like to believe :p

    Depends on the vape. The herb can sit in a MiniVAP all day long and not see any conduction.
