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.

G2 Turbo on an ordinary backpack without hipbelts.

On a school backpack with small hipbelts.

On a backpack worn by a user. It is sitting between the backpack and the user's back.

HOW IT WORKS? 

Presti G2 Turbo is a powerful blower designed for use with a backpack. It can be attached to your backpack and when you put on your backpack, it can generate a strong convective airflow between you and your backpack to circulate the air and keep your back cool.

The outlet of G2 Turbo faces upward, so the air will move from the bottom of the backpack to the upper part of your back. With the use of a heavy duty motor, the convective flow can disperse the air between you and your pack and take away the heat generated by your back instantly, making your back always stay cool and sweat free.

HOW DID WE MAKE IT COMFORTABLE TO WEAR?

After seeing the pictures above, some of you may ask: Will the fan press against my back when I put it on?

In fact wearing comfort is the most challenging part of our project and is a big concern for us at the beginning. Fortunately we have found the solutions and at this moment we can assure you G2 Turbo will not make you feel discomfort physically because we have solved the physical problems already.

As you may know, the human spine has natural curvatures. When you look at it from the side, it has two alternating curves to create an "S" like shape.

When a backpack is worn, in fact a hollow/empty space will be created between it and the user, whether he/she is fat or thin.

G2 Turbo is designed to fit and "hide" in this space. The idea is represented by the schematic diagram below.

   

 

 

ERGONOMIC DESIGN:

The case of G2 Turbo contours to the shape of a human body. With the ergonomic and extra thin design, it will match perfectly with your body and your backpack whether you are fat or thin.

HIGHLY ELASTIC RUBBER:

Besides the shape, the material selected to make the G2 box housing will be highly flexible and soft. This ensures G2 Turbo will sit against your back evenly and comfortably. 

POWERFUL, QUIET AND DURABLE MOTOR:

A powerful centrifugal fan will be used to make G2 Turbo. Centrifugal fans are sturdy, quiet, reliable and capable of operating over a  wide range of conditions.

EASY TO MOUNT AND USE:

Simply insert the two shoulder straps of your backpack to the tailor made clips of G2 Turbo and connect the control cable to a power bank, you are ready to go on a day hiking trip without worrying the backpack sweat issues. Since it is attached snugly on the back of your pack, it does not have any effect on your use of backpack.

SWAPPABLE AND SAVE MONEY:

Some of you may have owned more than one backpack already, you don't need to buy a new backpack to avoid the backpack sweat. G2 Turbo is designed to fit backpack of different widths, so you can mount it on at least one of your backpacks.

ADJUSTABLE FAN SPEED:

The fan speed of G2 Turbo can adjusted continuously, so you can set the volume of airflow to a level which is most comfortable and suitable for you.

VARIOUS POWER SOURCES: 

Use it at any occasions when you are wearing a backpack, using a power bank or rechargeable and replaceable AA batteries inserted inside the built-in compartments.

* See also battery run time chart in the specification section below.

2-year warranty:

To prove our confidence in what we have made, every fan comes with a 2-year warranty on the motor and fan blades. If at any time your motor malfunctions, we will replace the entire fan, no questions asked. The warranty is limited to the motor only, not the fan cable and USB circuit board.

 

THE REWARDS

COLORS

At the beginning, there will be 2 colors for your selection only. If G2 Turbo can be successfully funded, we will add more colors to the list when we introduce stretch goals.

SPECIFICATIONS

- More on Sizing and Fit 

We hope and we have tried to design G2 Turbo's mounting as easy as possible and make it fit for different backpacks.

However, there are still some backpacks which cannot be used with G2 Turbo at this stage:

1. The small packs with width less than 270mm/10.6" or large packs with width large than 330mm/13".

2. The large backpacking packs with large hipbelts.

WEARING GUIDE

Airflow direction of G2 Turbo is from the bottom to the top, so it should be located to a level within the inward curved region or above the user's hip.

Tightening or loosing the two strap adjustors to find out the optimal position of your G2 Turbo after you put on your backpack. You can find it out as long as your backpack's width falls within the given dimensions.

 

 

 PRODUCTION  

HOW WE GOT HERE?

There are many different types of backpacks and we all may have owned at least one or two and love using them in different occasions:

But, as you know, all of them have one big disadvantage: they always get your backs sweaty.

When we put on a backpack, our backs are smothered. There is no air gap and ventilation between you and the bag, to allow the sweat to evaporate and after a certain period of time, the sweat collects into a big sweaty wet spot. So regardless what types of backpack you are wearing, including the ones with air flow mesh, your back always ends up soaked with sweat even in just warm days.

For this reason, we decided to make a ventilation fan for backpack users and for ourselves as well. Several prototypes have been built to evaluate and prove the ideas already. The shape and thickness of G2 Turbo were determined through trial and error method. After several iterations, we have been able to obtain one which can perfectly match both a backpack and a wearer's back.

Proven record of making fan products and handling Kickstarter project. We successfully completed a project on personal fan last year and have experience of reward fulfillment and product warranty.

 WHO WE ARE?

Our team is comprised of experienced product specialists and supply chain expert with more than 20 years of project management and manufacturing experience. Our aim is to build the products with super quality and user experience.

 

                            

 

                            

 

                            

 

 

Risks and challenges

Initial Samples:
We have already built several prototypes and engineering samples by ourselves and will arrange our manufacturer to build it for us in a timely manner. We may have to extend our sampling period if the initial samples cannot pass our First Article Inspection.

Production:
Production delays are unlikely. A factory specializing in manufacturing electronics products, metal and plastic parts will help to assemble the fans. They will be able to make the first shipment within 30 days of successful project funding, so you can enjoy your Presti Fans before the summer travel season kicks in.

Shipment:
We will ship them to anywhere in the world via tracked shipment, so we don't expect any issues.
