What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

Greetings from Singapore.  

About 2 weeks ago, I have randomly selected pledgers from the current project from USA, Germany, Italy, Finland, Australia, Singapore and India. I proposed to them to test my product. When they agreed, I sent them the product on goodwill basis. I am confident of the quality and performance of my product.  

To date, 4 pledgers have given me their feedback and sent their pictures. Two more pledgers have given good review and will send picture this weekend. One package is missing in delivery :-(.

Please visit 

www.prufen.com/landing-page 

 to see their feedback and pictures. Construction of the the page is work-in-progress so not all buttons work.    

For the kind and helpful pledgers who have helped to evaluate my product, I would like to say a big THANK YOU. Many have given useful feedback and I really appreciated them. Thank you very much again.

Good News!!!  New Auto-Power off timer feature.

We have successfully added a "auto time out" featue to our cable.  One can set 2,4,6,8,10 hours.  When timer is done, the cable will automatically shut-down its power to the phone.  The timer is "not activiated" by default.  To activate/deactivate, hold the button for 4-5 sec.

There are cables in the market that claim to shutdown power when battery is fully charged.  Many of these cables use "low current" flowing through the cable to guess if battery is fully charged.  This method is a guessing game because different phones have different "low current".   The crude method will result in some cable powering off pre-maturely.

 Current price is S$26 (US$18.30) at Kickstarter.  We expect to launch the product at US$26.

Thank you for visiting our project.

We launched Prufen Smart USB Cable in Singapore in Comex Exhibition in Sept 2016.  With its safety features, mAh meter and superb OLED display, the response was overwhelming with 70% of customers buying our product after seeing our product demonstrations. We are encouraged by this response and believe we have an winning product. We now want to progress forward to bring this product to key global markets.  

Why we need funds:   

1. We would like to sell our product in KickStarter to determine the potential demand in key markets. With this information and fund, we can then approach key physical and online retailers with our KickStarter's data.

2. This product is the World's First USB cable with auto-stop charging safety features coupled with a mAh (energy charged) Meter to measure the mAh of power banks and mobiles.  This cable can also do data transfer. Being a World's First, it is absolutely critical to explain to potential customers of the product features. No customers will understand the product just by looking at it (unlike familiar products e.g. headphone, speaker, power bank...etc).  KickStarter will allow us to test our existing marketing material (eg. our video).   When gaps are identified, we need funds to develop and invest in more marketing materials for both physical and online sales.  

In case you are wondering: No, this product was not invented due to the recent mobile battery problem of a major phone maker.  We have foreseen the needs to have safety features and mAh meter more than 2 years ago.   Patents were filed in 2015.  

Thank you again for viewing our project.

It has come to our attention that there are other projects that claim to have similar product and features.  Here is how do you can call out their false claims:

1.  To support high current charging in Fast Charge,  it is important to have a thick cable so as to have low impedence otherwise it is not going to work.  General rule of thumb is to be suspicious when a product uses flat type of cable.  Why are cheap cable cheap?  That's because they are selling you plastic and little wires.

Prufen's wire is also shielded to minimise EMI (electro-magnetic interference)

2. They make false claim to have pending or awarded patent but there is no patent reference number.  Prufen filed patents in 2015 and currently they are patent pending.  Patent number pendings:  14/892.966  104136824  050401

3. They make dubious claims to have CE and FCC conformity.  But again there is no certificate numbers to verify.  Prufen conforms to CE (cert. no. CTL1610244101-EC) and FCC (cert. no. CTL1611184201-FC). 

4.  They make dubious claim that their Apple connectors are MFI.  Prufen's Lightning adaptor comes with a shorter power-bank (23cm) type of cable.  Therefore besides getting the Lightning adaptor pledgers will also get the 23cm USB cable free.  Therefore it is a 2-in-1.  Below is screen capture of Apple MFI website to prove that our adaptor is MFI.  https://mfi.apple.com/MFiWeb/getAPS.action  Prufen model is PLC-BB

Genuine MFI Certified 2-in-1 ie. Cable with Lightning Adaptor

5. They claim that their cable can improve speed by 3X to 11X.  C'mon, the professional engineers in Apple, Samsung, LG, Appo...etc are no idiots.  LMAO.

6. Check if they support charging beyond 5V.  Many Android phone makers are going beyond the conventional USB specification of 5V eg. Samsung's Fast Charge is charging at 9V.  Prufen is able to support up to 20V.  That's future proofing. Many of the copy products are inferior product that can support only 5V.

7. Check if they support charging beyond 2.0A.  Eg:  Apple iPad and Huawei are charging at 2.1A and 2.0A respectively.  Many of the copy products are inferior product that can support only up to 0.999A.  Prufen supports up to 2.5A.

8.  Type of display used.  Many of the copy product uses cheap out-dated LCD display.  Prufen uses expensive but superior OLED display. Google OLED if you want to know more about OLED.

Thank you.

Risks and challenges

We have produced and sold our first 1000 set in the Singapore market. The product quality and feature performance are proven.

The key risk and challenge of this product are:
(1) the ability of our marketing material to communicate effectively on the product features. Customers have no idea of the features by just looking at the product. Being a world's first product, it has its own unique obstacles to overcome.

(2) If features are not communicated effectively and/or poor sales response from global market we may have to give up this product.
