Greenivative started the way any other big innovator did – with a dream.  Their dream was simple: to offer a portable power device that you could place into the hands of men, women and children around the globe that could help them with the growing problem of unavailable power.  Whether that was due to a tragic disaster, or an outdoorsman needing handheld emergency power, G-MAG® wanted to be there to ensure an easy and affordable way to charge devices using the Earth’s most abundant resource.  Now, no matter where you are, you can keep your cell phone or other portable device up and running using only salt water.

Since we were kids we were taught to be prepared and shown the areas of this world who simply cannot afford that luxury and the advantages of portable power.  If catastrophe strikes, some people just can’t get the power that they need to survive the week’s end. This is why Greenivative set out to change the future and strive to get our G-MAG® portable power in the hands of everyone out there who needs it.

Simply put, they wanted to make a portable homesteading battery charger that was not only easy to use, but extremely inexpensive and practical as well in an effort to make our Earth a better place for all who live here.



Everyone nowadays wants to go green.  This means having a deep, passionate understanding of the importance of saving the planet using any means necessary.  Greenivative shares this passion with you.  They set out to create an off the grid charger that would not only help millions of people worldwide, but would help the planet as well.  A happy and healthy Earth means happier and healthier people, so we set out to make our portable battery charger the easy choice for anyone needing clean, affordable energy.  It’s time to start thinking about the environment, so check out Greenivative’s emergency battery recharger and discover for yourself all of the applications it can offer you.
