      Mr John L Dowling on

      Guys
      Why is the shipping cost so ridiculously high for people outside the US. It is US $35 to Australia or AUD 47. So what's the point of a US$25 discount? Does not anyone ever consider exchange rates for loyal customer beyond the US. I use a US based forwarding service that can do a much better job than your pricing. Perhaps visit Comgateway.com!!

      Hello Linearflux team.

      The shipping cost to my country is actually 2x the pledge.

      Is there are way you could reduce it?

      Guys, just wrote u an email regarding an issue with your Linearflux product.

      Sent from XXXX@gmail.com (u'll find it on your orders@Linear....etc or the KS private message) - it has pictures attached.

      Message:

      Sorry to bother again, but as u can see the pictures attached, my Linearflux is not working properly. I sent u guys a month ago some tests I made and I had no reply till 2 weeks later.

      As u can see from total dead iPhone to full charge it took 3 HOURS AND 30 MINUTES. Theres a hand watch beside the phone for the test. Also, I use ONLY APPLE MFI Certified Cables!

      @kenny nothing is wrong with your charger, the amount of charge your iPhone takes in depends on a number of critierion within the charging circuit of your iPhone. For example, if the unit is at full brightness and is being used, wifi and bluetooth on, video is streaming etc all have a factor of how much power the iPhone will allow the HUB to provide.

      @sokompheak please reach out to us at orders@linearflux.com

      Hi there, I am using iPhone 6s Plus. I have done several testing using a USB voltage and ampere meters. I found that the 2nd port can give a max 1.7A to the iphone and the 1st port constantly give 1A. Is there something wrong with my charger? Also my LithiumCard Pro get very hot easily.

      Hello, last week i left my iphone 6 and Sony M4 charged with HYPERACHARGE whole night. Then in the morning I check both devices, it's not been charged their battery! now it is stop working!!!

    14. LinearFlux USA Inc 3-time creator on

      @Jorge please contact us at orders@linearflux.com usually rewards are not sent out because we did not receive a reply to the product survey or there is additional shipping charges that are still open

    15. LinearFlux USA Inc 3-time creator on

      @FVI it's great attempt to test units out for yourself but we have seen the testing you sent us and it's a bit flawed. We can't really verify your testing gear or experience but you also need an ammeter to accurately test your setup.

      You initially started the phone with X% battery capacity left and began charging with a chargetech. You then switch to using the HUB when the phone is at Y% battery capacity full. This is the point where your testing is heavily flawed! To keep consistency between tests, you will need to start the tests when the phone battery capacity is at X% on both charging instances.

      You may be wondering why? Well it's because phones have a built-in charging VI curve. As the phone reaches full capacity their input charging current is dramatically reduced. This is the reason you saw a different charging % when you switched from the chargetech to the HUB. If you perform the tests indentically you will see the HUB is much faster and more powerful than the competition. Chargetech is listed at 2.4A max for both ports combined. The HUB is rated at 3.5A combined!

      Also, per your last question, HYPERPORT 1 is maximized for Android devices and HYPERPORT 2 is tailored for iOS devices. This is also mentioned in the packaging. Happy HyperCharging!

      Hope that helps!

      @CREATOR...... I've donde 2 tests along with the Hypercharge Hub and my Charge Tech Wall.....I have 4 screen shots showing the details between both running a 25 min Test and comparing the increment of battery % ...... quite disappointed. Charge Tech has a pretty good advantage leaving behind the Hypercharge Hub..... I've sent u an email to orders@.... i think my hypercharge hub might have something damaged or something. I'm now in Colombia, South America......it's going to be quite tough to pay a shipping depending on your solution. By the way, why does the Hypercharge Hub don't say iOS and Android beside de USB connectors as shown in your official images? They say...Hyperport 1 and 2.....

      @sokompheak that's normal because the HyperCharging circuitry providing safe and fast power to your devices. Like a Ferrari engine, the byproduct of it's fast charging is some heat.

      Mine arrived a long time ago and I have been using until last week it stopped completely working. It does not charge in either outlet and I have tried different cables thinking it was the cable and it seems that's not the problem. What do I do?

    39. LinearFlux USA Inc 3-time creator on

      @Moi Your order has been on hold as we did not receive a response from you regarding the additional delivery phone number. The email was sent to you in January. Alternatively, you can send your phone number to us at orders@linearflux.com

      @JEL thanks for the compliments! Funny you mention upgrade plans on our roadmap. We will definitely keep you on our beta testing list for testing future LinearFlux products. Which is happening very soon! We'll keep in touch!

      @kenneth lin yours will be shipped this week. Thanks for providing your info.

      Thanks Adam!

      Hi I just want to say thanks to Linearflux for their great service! My new Lithiumcard Pro is really useful - do you have any plans to upgrade the capacity for more of a charge for the iPhone 6s+? Also with regards to my Hub, it's still working great and it charges my Apple products a lot faster than the standard charger. I think a lot of people might be complaining because they have non-Apple products that already have speed charging built-in to their chargers... I can only speak for myself as an Apple user: the Hub really does charge my iPhone and iPad faster, and same goes for the Lithiumcard Pro. Thanks Linearflux!!!

    43. LinearFlux USA Inc 3-time creator on

      @Darren thanks for the continued support and are happy that you are satisfied with the HUB.

      @JEL thanks for your patience and support!

      @contributors who have not received their pledge. There's less than 2% of you who have not:

      a) replied to the survey sent after the campaign
      b) you have not sufficiently paid for shipping. Some go as far as listing a USA address then changing it to an international address to skip having to pay for international shipping.

      If you are a contributor and still have not received your reward, we will be reviewing your messages all this week to clear the issues with your particular order.

      @Joshua we sent you a return label in March but you seemed to have not received it. We resent it to you again.

      I would like to order a couple more Hypercharge hubs. I just love this product so much, I'd like to have a few more around the house and for travel. Please get back to me on how to order a few more.

      It's totally disrespectful that the product didn't arrived and I didn't get any answer. It's a shame because I trusted on you and pay for it!! I think the best way to get an answer is go after my legal rights!!

      Hello? Anybody? Does anybody actually work at LinearFlux or is it standard practice to screw over the people that help you launch your products? I was perfectly understanding when I received a broken hub. Stuff happens, no big deal. But when you fail to do the easy and right thing after you say your going to do it, pathetic. Maybe you should start a Kickstarter for a customer service department.
