About this project

Octofire in the News:

Our Story:

We wanted a charger that can charge everything in our homes. Almost all our family members had a Smartphone. Also, most of our homes had a couple of tablets (some had iPads and other Android) and iPods. In total, we wanted a charger that has more than 6 USB ports and can charge almost any type of device. We started looking  for a multi-port USB charger, but our search on Amazon and other places yielded chargers that had no more than 4 ports. Even with 4 ports, they were doing only 1 Amp per port which is not enough current for optimal charging of tablets (normally tablets require 2.1 Amp current). Also, these chargers were designed for particular brands like Apple, Samsung etc. and none of them were supporting optimal charging in an intelligent and brand independent way. 

This is where the idea of Octofire came from. It was a difficult journey, but we took up this challenge. We set out to design a charger that can charge almost any USB powered device under the sun. This required an intelligent circuit that is capable of device detection and USB port configuration, leading to optimal charging. In addition, we wanted this charger to be able to deliver enough power to charge 8 tablets at optimal current simultaneously. 

After months of design work and testing, we are pleased to say that we have achieved what we set out to do. Now, we have a working prototype that is near production. We are very excited to share this product with you, and would like you to be part of our team by supporting this project.

Whether you are a family, small business, restaurant, doctor's office or anyone with large number of digital devices like tablets/Smartphones, you will surely appreciate the convenience this product will bring to your life.

Features in a Nutshell:

Safety: Safety is the first and most important feature of our design. Our AC/DC adapter is UL, CE, FCC and RoHS Certified to give you peace of mind. (It has everything: overcharge, over-voltage, overheat & short circuit protection.)

Ultra Fast Charging: It charges 8 USB devices (simultaneously) each at up to 2.1A / 5V power.

Smart Detection: Intelligently detects your device and provides optimal charging as per the device.

Design: An elegant design to fit any small corner or even under your computer table, making sure none of your devices run out of battery when you need them.

Sleek: The sleek Octagonal shape makes the device look impressive and the high end black polycarbonate ABS material used for it makes it durable and efficient.

Ease: Worry free operation. Plug and rest is taken care of by Octofire.

Economical: We made sure that it is a affordable and does not break your bank.

Compact: It is a great companion on your trips when you need a fast and speedy charger to make sure all your devices are running all the time.

Efficiency: Highly efficient Octofire will waste very little energy and will still everything like smartphones, tablets, GPS, Bluetooth headset or any other popular electronics that are powered from USB port.

International Compatibility: Octofire takes 100-240VAC 47-63Hz power input. That makes it work in all countries. It will be shipped with your choice of AC plug of US, UK, EU or Australia Style. 

Warranty: Octofire Turbo comes with a 1 year Replacement.

Design Story:

Skiva Power Flow Octofire Turbo was designed to enable fast charging of multiple devices simultaneously. It took us a long time to design a complete solution for that. After a long research and rigorous testing, the device came into existence, and is finally ready to make a mark in the industry for being the first device of its kind.

We started out by experimenting with intelligent detection of devices to optimized charge current, as well as finding best in class DC to DC conversion IC. We choose a DC to DC conversion IC that is being used in high end server farms and is very efficient. This enabled us to make a design that does not need a fan to cool it even at peak loads.

Below is the progress of PCB design from early prototype to final design that we have it today:

 We also put a lot of emphasis on usability and form factor design, we made multiple design prototypes using high precision CNC machines. Below are a few milestone points in plastic design.

Ready to Market Prototype:

Finally now at this stage of development we have verified all aspects of design. Below video show working prototype charging eight different types of devices simultaneously:

Below are some closeup shots of final prototype :

We have tested this charger with anything that we can get our hands on and it was able to charge it. At the end of this page you will find a list of devices we have tested along with our component partners. Note that even if your device is not listed, we are 99% sure that if your device works with any third party USB charger, it will also work with OctoFire.

With your help, we can reach our stretch goals. Below colors will unlock for everyone to choose from at the end of the campaign at specific goal points.

Project Progress:

We have an early prototype ready which is being tested over past couple of months. Now we are almost ready to create tooling for plastic and electronics. 

With your support, we will be able to do production of 1000 units by February 2014. We have already negotiated with the component suppliers for the availability of the components.

Octofire Turbo prototype has been subject to multiple cycles of development, testing, and improvements. We are very confident in achieving our production goals with your support. 

We will also back this product with 1 year warranty.

Risks and challenges

Today, we have a working final design prototype in our hands. We have been testing them for a couple of months and everything is working as expected. We will now need to transition from our ready to market working prototypes to actual shipping products. We have talked to our component vendors and secured component supply for production. We have an international partnership with a reputed manufacturer. So, the risk factor has been reduced to logistics and any unforeseen issues on production line. These unforeseen issues may take time to resolve, and can cause delay in delivery. However, we are confident that we will deliver on time. A serious design problem in the product is very unlikely because of the amount of testing that we have already performed on our final samples.
