About

Important notice

after we received some potential backers feedback we decided to make important improvement of our device.

Potential backers asked us if powering from running water would be possible...

...an answer is positive.

while constructing our generator we already have included momentum control via adjustable stator core magnetic conductivity.

So we will add to every BeachBox a propeller which can be connected instead of powering with the wind. We just need to redesign generator mounting when in the casing and make a hole in the casing. If you have running water available show goes on even more brightly...

BeachBox is world's first portable wind and sun charger for USB devices on the go with an integrated Bluetooth speaker that really works when you are out of the reach of grid power for a prolonged time.

This picture is 3D model render of the BeachBox, real photos of a current device are on this site.

If you wanted a charger that would breathe life into your lifeless phone or tablet using nothing but the wind and sun, this is your day.

It's a life long story... about phone going out of power just when you need it.. and no power grid is near...

Our mission...

is to help people extracting power from nature wherever they need it. There is plenty of it around. We have the knowledge to do big devices but this time, we limited our goal to help people have their smartphones and similar devices fed up. Other power needs follow in the future if everything goes right. We have in mind that we want to provide best value product per power it provides to its owner available at the moment. Thank You !

BeachBox

BeachBox collects energy wherever you place it, energy from the sun and you can also set up a wind generator which sits inside it. Detachable blades which fit into BeachBox play the most important role here. BeachBox charges up to 2 USB devices at the same time ... never run of power for charging your smartphone or for powering built-in Bluetooth speaker.

How we made it?

We all know there are plenty of similar devices available... power boxes, solar powered banks.. hand driven generators and similar but none of them can really permanently charge... so we started to think how could we change that...

We carefully analyzed smartphone power consumption and came to a goal for our device... about 5 watts of power is needed average smartphone user to remain happy :)

We made several different wind generators... also vertical axis ones ... and found that vertical axis generator is not suitable for portable small device cause of its low efficiency and high wind needed to start giving usable power. We also have seen some campaigns on this site who claimed that vertical one will do it, but none kept their promise... and delivered working device by this time... So we decided to use more common horizontal axis wind generator for our BeachBox project. We only like useful devices.

We think only our way producing 5 Watts at least is the right one !

 Why we use only 2 blades...

 Also, we were surprised that generator with 3 blades has only 3 percent higher efficiency than 2 bladed...

 so we use a minimal number of blades saving us space and weight...

 We use downwind configuration of blades so generator doesn't need a tail wing and keep generator simple and efficient with a minimal number of parts.

 Also, we found that 3d printed generator blades have an advantage over plastic injection molded ones cause we can make air bubbles where desired in the wing to make it lighter and elastic... so the wings can deform when the wind is stronger and we can make pitch control with fixed wing that way. It greatly improves aerodynamic efficiency.

Our wind generator uses detachable blades so it can fit into a BeachBox. Connector part is currently pending for UK patent.

This construction of connector is simple and proved itself to be very reliable. It also prevents damage by disconnecting itself at a certain force. We tested 10000 cycles of connecting and disconnecting and very little wear appeared.

Blades are 200 mm long each. The distance between wing tips is 490 mm. Total swept area of blades is 0.189 square meter.

Power produced from wind generator :

1.5 Watt at 4 m/s , 

5 Watt at 6.5 m/s, 

18 Watt at 10 m/s

We used anemometer for reference wind speed measurement. Both were connected to the same mounting pole approx 1 meter apart to obtain reliable measurement results.

BechBox micro uses smaller wind generator which produces approximately 40 percent less electric power at same wind speeds.

First prototypes used 8 magnets in the rotor and 8 coils in the stator. 

Old 8 magnet rotor plan...

Later we changed that to 4 magnets and one  U - shaped coil. We also tried adjustable core for stator coil so regulation of force that turns rotor is possible.  This feature is very useful when you need to capture the low wind. 

On BeachBox prototype, we use 2 solar panels which give each 2 watts max power so 4 watts at the maximal sun and best possible orientation.

BeachBox mini solar panels give up to 3 watts of power.

BeachBox micro solar panels give up to 1,5 watts of power.

We deliberately positioned one of two solar panels on BeachBox's cover so angle towards the sun can be adjusted with simple stay out mechanism.

The electronic board

  is made very minimalistic and user-friendly with replaceable parts so it can easily be maintained in case of damage. It is made with a couple of-of the shelf integrated circuits. It mainly does voltage regulation for battery charging and powering USB outputs, plus it has three modes of operation controllable by one switch with 3 positions. Very user-friendly and reliable ! 

Most important advantage of this circuit board is that can operate without main battery due to its own capacitor of course only when an inflow of energy from solar panels and/or wind generator is present. As you probably noticed in the video it also has an audio input jack for plugging in musical instruments...

We used 6V 2Ah lead acid battery in our prototypes which could be replaced with smaller or larger depending on needs. Space for battery in BeachBox is provided for up to 6V 10Ah battery.

Bluetooth speaker in prototype had it's own additional 500 mAh battery which was charged from the main circuit.

The battery inside can charge an average smartphone at least 5 times (BeachBox) without solar and the wind, if the wind is present BeachBox can charge phones and play the sound continuously. If only the sun is present speaker can work for an indefinite time and also one charge for smartphone per few hours is produced and reserved.  The battery inside BeachBox can be also precharged via grid 240V (only BeachBox and BeachBox mini) or USB or 12 V outlet in a car.

Talking of self-sufficiency and design rolled into a package – the BeachBox fits the bill.

We will try to answer any of your questions. Backers can send a message here. Others can contact BeachBox team at email beachbox@beachbox.mobi 

Why we need your help ?

Basically, we need your funding, to make a new more advanced shape of BeachBox for which we believe will not disappoint any user of it. We already have 3d plans of it and will be made with 3D printing technology first later with injection molding technology. Our development of the BeachBox is constantly in progress. We believe many people want to use wind energy but don't have proper conditions to make such device on their own.

About funding goal 2.999 GBP

we have precisely calculated a list of expenses which we have with the production of any BeachBox, so we could, for example, theoretically start a campaign for 229 GBP and offer only one BeachBox... but we expect more than 100 new happy BeachBox fans.

Warranty and spare parts

Every BeachBox comes with a one-year limited warranty.

We are aware no one likes devices that go broken frequently... We tried to construct our device with that in mind. But if anything goes wrong we have spare parts documentation. Every BeachBox comes with its serial number telling us exactly which parts it is made of. 

Documentation is precise so we won't have any difficulty to supply your spare parts if/when needed. We had repairability on mind when we constructed BeachBox. We'll keep most of the spare parts in stock. We used commonly available parts for its construction. That means we used of the shelf bearings, axle, ...etc. We used best available quality parts, not to cause any easily avoidable malfunction.

Shipping costs

we used prices of UPS saver express service for our sending costs calculation. If you find better carrier service for your country we will put that option in so you will be able to choose it. 

Conformity

Before pledging for any of our products please check your local regulations. All parts that our products consist of are certified for use in the European Union. Currently, we are in a process of obtaining the same certificate for the whole BeachBox. 

Risks and challenges

Risks and challenges

There is always potential challenges to every Kickstarter campaign.
Everything is ready to go, but there is always the possibility for manufacture problems, delivery delay, missing delivery etc. But we are confident in our ability to get BeachBox to every single backer and we will do our best to keep to the schedule.

Thank you for checking out our project, please share!

Power on!
