## Description

Product Description          LithiumCard, the world's only "Rechargeable Hypercharger" by LinearFlux. The business card sized LithiumCard Provides a radically different approach on how smartphones, Bluetooth speakers, and portable devices are recharged. Hallmark and patent pending features include: hypercharging speed, fully integrated cables, simultaneous bypass-charging, dual-stage protection circuitry and includes an all convenient NanoStik pad to keep it nice and elegant.             From the Manufacturer           $185,985 raised with 2,038 backers.  HyperPort Specifically developed to be compatible with the new Apple Watch! The PRO's exclusive HyperPort feature enables you to charge another USB equipped device. Just plug your own USB charging cable (not included) into the PRO's additional USB type-A port to share HyperCharging with your friends. Turned Up To “11”. Our latest HyperFET Gen2 technology has pushed the envelope of what's possible today. Nothing in its class, or size, can deliver up to 3 Amps of power. The PRO has been future proofed to meet the ever increasing power demand of smartphones today and tomorrow. For example, the Apple iPhone 6 PLUS can actually demand over double the power (2 Amps) than the 1 Amp charger it comes with. The LithiumCard PRO can deliver up to 3 Amps of total power. As future generations of smartphones require more power, the PRO is more than ready to handle higher power demands with ease. In Sync. Backing up your smartphone's data to your computer has never been easier. There's no need to carry another separate cable for syncing data to your computer ever again. The PRO does it all. Charge Ahead. HyperFET Gen2 circuitry is capable of charging your smartphone over 1% per minute compared to the original LithiumCard. For example, if the LithiumCard PRO is left to charge your smartphone for 15 minutes, expect up to 15% of more in additional battery capacity. Advanced HyperCharging battery management algorithm extends the battery capacity beyond its 3000mAh rating. Meaning, you get more capacity than typical 3000mAh battery chargers. Charge Everything. LithiumCard charges most popular smartphones and electronic devices available today, such as Beats Wireless headphones or Jawbone Jambox. It has an Apple Lightning connector for your iPhone 6 and iPhone 6 PLUS, or a microUSB connector, for your Android phone. Built In. The PRO has all the cables you'll ever need. Use the full size USB to charge the internal battery. And pull-out the microUSB, or Apple Lightning (sold separately), to charge your Android or iOS devices. As with the original LithiumCard, the cables for the PRO can be hidden from sight when not in use.LithiumCard charges most popular smartphones and electronic devices today, such as Beats Studio Wireless headphone or Jawbone Jambox Mini. It has an Apple Lightning connector for your iPhone 4,5,6/6S, or a micro-USB connector for your Samsung Galaxy S6. It also charges the Apple Watch!

    Great Charging Speed, Bad Battery Capacity
  

*by N***L on Reviewed in the United States on March 26, 2016*

PROS:- charges really fast (my phone was at 30%, and within the hour it was fully charged! But keep in mind that I didn't use my phone AT ALL while it was charging)- lightweight (easy to carry around)- quite thin and slim, looks neat and professional (it looks a bit bulky in the pictures online, but compared to my phone - LG G3, it's only slightly thicker, which is pretty amazing!)- built in cables (1 micro usb and 1 regular usb output) (I love not having to carry extra cables with me; I just need 1 item in my bag now, the lithium card itself)- 2 input ports (1 micro usb and 1 regular usb input) (Great for charging multiple devices, but I'm not sure if this works)CONS:- NEEDS MORE BATTERY CAPACITY (it's only 3000 mAh which is weaker than the average smartphone battery these days)...So within a full battery cycle of the lithium card, if I don't use my phone while charging, it would probably give me an extra 70-80%. But if I use my phone while charging, I only get about 10-20% before the lithium card dies, so just make sure you don't use your phone while charging (which is impossible for most people).- quite pricy (I paid nearly $100 CAD, but I think it's worth spending only $50 CAD on this)- the light keeps flashing when it charges, which can get annoying (I thought it would just glow instead of flash), but you can turn off the light completely while charging- needs more light/colour variations for battery level (white is 90% and higher, blue is 10-90% and red is under 10%...they should balance it out like white is 70-100%, blue is 20-70% and red is 20% and lower, or put in a green light for variation in power level indication)- cables are VERY short (this should have longer cables or extending cables, because every time I need to use my phone while charging I need to carry the lithium card in my hand while holding the phone, and it gets super inconvenient)- nano stick pad is good but doesn't stick to everything (and honestly, I don't see the need for it, as I always keep this flat on a table surface and not against a wall or anything)...I tried sticking it to my cpu tower which is made out of plastic and it was sliding off almost every time. It sticks really well on some surfaces, and not at all on other surfaces.- input ports are quite difficult to open (they have their own individual plastic covers that close the ports, and removing the covers with your fingers gets real tricky..you would be better off with a toothpick or something)OVERALL:- it's probably the fastest power bank I've used, definitely worth having- more battery capacity would be better (at least 6000-10,000 mAh)- few design flaws (needs longer cables, better light indicators)

    Lightweight but has not performed as expected.
  

*by G***S on Reviewed in the United States on February 29, 2016*

I have an HTC One M9 cell phone.  Overall, it did not charge as expected.  After receiving the PRO, I charged it up to 100%.  Then, I  charged my phone two different times to about 65% average before the PRO drained out. The second time I actually turned off some settings in the phone like location and put the phone in extreme power saving mode and still came out with 67%.  Both times it took about 1.5 hours to get the phone to the percentages I mentioned.  Did not clock the charging time on the PRO itself yet but it was probably around 2 hours off a laptop if that.  It is lightweight though and I do like it for that.  I don't have a lot of apps on my cell phone so not sure why it does not give a full 100% charge.

    Slow to change Samsung galaxy s7
  

*by G***R on Reviewed in the United States on July 30, 2016*

Disappointed that charging of the Samsung galaxy s7 is way slower compared to Samsung Galaxy s4. I understand there are many factors that affect the charging speed. Seeing how the SSGS7 "fast charger" can do the job in less time.I do use this device was a standalone power supply for other peripherals.
