Howdy guys!! So cool thing about me; I'm in field marketing for DEWALT power tools so I get some cool stuff sometimes. This right here is a portable power station. It takes 4 DEWALT 20V batteries of any size and puts out up to 15 amps. It also attaches to our Tough Cases so you have a place to put all your necessities in the boxes stacked up. And the cool part, you plug the inverter in to the wall and it charges all your batteries at the same time when they are dead. Let me know if y'all think this is cool or have any questions. Not selling anything just thought you might like it and hope it makes your drone experiences easier away from power.
