The PowerOak K2 is a multi-use All-in-one powerbank. It can charge up to 6 devices simultaneously. It has one 20V/3A, one 12V/2.5A, two 5V/2.1A and two 5V/1A outputs. And it can be charged with an AC adapter. The PowerOak K2 is a real life safer, you never have your laptop, cell phone, tablet run out of battery when you take along our long-lasting 50000mAh K2. No need to find electrical outlet when you're on business travel, going camping, etc.  

So we already have a powerbank that has one of the best battery capacities in a really compact body. But PowerOak want to be an innovative company, that produces sustainable products fully independent from the power grid. So that is why we call for YOUR HELP on kickstarter. We want to transform our PowerOak K2 to the best Powerbank now available by adding solar charging capabilities! This way there is never need to find an electrical outlet. With the PowerOak K2 Solar you are not depended off the power-grid anymore. So support us and get a PowerOak K2 Solar in a couple of months and explore the limits of sustainable energy and off-grid living.

 You may be for sure aware that there are more portable solar systems. They are already on the market and are being sold as they are the latest what the technology can offer. Not true my folks. PowerOak is currently the best available device in any sense.

  • Best power to weight ratio
  • Best price to battery capacity ratio
  • Best battery technology with more than 1.500life cycles (90% Depth Of Discharge)
  • Built out of best available components what ensures true durability
  • Solar powered charging with 76W (when fully developed)
  • Biggest battery capacity

Designed and developed in Eindhoven (The Netherlands), and manufactured abroad by KayoMaxtar, we can guarantee that we have been using the best components available to make our system a real life saver in most harsh environments.

The PowerOak K2 can be charged with a AC adapter like you are used to with most devices. But when we are finished with the PowerOak K2 Solar, the K2 will also be capable of being charged by a Solar panel with a maximum of 76W. You can buy our predefined solar panels or you can use your own as long as the input voltage has a range between 16V and 40V and a maximum total power of 76W. We can offer you these 3 types of solar panels. They are all predefined and can be used to charge the K2. They are light and fold able. Furthermore they are made of fortified PVS so they can withstand most harsh environments.

PowerOak is an initiative of a group of students. The project begun almost 5 years ago after a power black-out in Eindhoven, The Netherlands. There was a major problem with the distribution of energy. The utility company expected to solve the problem within 3 days. As a temporarily solution at that moment, the utility company offered fuel generators to every household, which every household accepted off course.

This moment had changed our mindset completely with respect to being off-grid and being independent from utility companies. Since then we have developed some pretty exceptional products like our PS10 which have been tested in this amazing project, see www.tinytim.nl

We have already developed our K2 as a standalone powerbank with more than 50.000mah. It has been proven as one of the best powerbanks and most powerful ones available, acknowledged by our customers worldwide. But we missed the final touch. We missed our K2 being independent from the grid. The possibility to be charged by solar power would really make our K2 an exceptional piece of equipment.

That is why we set up a team and researched how to add a new function to our K2. But as always it seemed a much harder task then we expected. How to add a solar MPPT and new BMS (battery management systems) to a pretty small casing and still offer the same qualities our K2 already possessed like weight to power ratio and price to power ratio.

Luckily, it is doable, as you can see in the photo's in the prototype section. There we show our prototype of the K2 Solar. In order to put our K2 Solar into production we need some additional financial resources that is also why we turned to Kickstarter for help.

 

Our K2 Solar Prototype. Same size and almost the same weight as our original K2, the challange we stand for is how to fit a solar MPPT and new BMS battery system in the already small case of our original K2.

Prototype with the first version of our circuit board. 

 

 

We will offer our first models of K2 with Solar Charging capabilities for early birds at some special prices. The K2 will be eventually priced at € 219,-. This is already a bargain with respect what other well-known companies are asking for their devices. To make it even more interesting we will offer our K2 for an amazing price of € 139,-.

 

 

For companies we have a special deal. If you back us up and order 15 units of a K2 at an already special price we give an additional reward to customize your K2 in the colors of your company, see example

 *All photo's off the K2 are from the original version without Solar Charging Capabilities. The PowerOak K2 Solar with solar charging capabilities will look the same, or really similar.

Risks and challenges

We developed a prototype and fiercely tested it.
We are CE compliant, passed all tests.
We are eco-aware and comply with strict environmental guidelines to the extent possible.
We technically resolved all challenges.
We are committed to Social and Global Responsibility
However, as with many early stage ventures, the future poses risks next to opportunities.

Some of this risks include:

1. Third Party Suppliers
We are relying on several third party suppliers for critical elements such as Batteries, Solar Panels and Molds. We do try, pending budget limitations, not to be dependent on a single source for any element in our product.
However, if a third party supplier fails, or goes out of business, we will undergo some expected delays in our production.

2. Changes in Regulations and Legislations.
Slim chances, but batteries, electric components and solar panels are subject to changes in regulation from time to time. Such changes may impose delays in production time.

3. Shipping to international backers, though we have been shipping Lithium Ion batteries for a while, can be difficult because of the regulations that vary and are ever-changing. We closely monitor these changes and work with our international shippers to ensure delivery to our international backers. Please contact us at info@poweroak.nl to get an updated information regarding shipping to your country

We have set a deadline for October 2016 to be ready to ship our products, but it could be off course a lot earlier.
