I bought both from amazon https://www.amazon.com/dp/B09G68HF3D/ref=emc\_b\_5\_t?th=1. My kids really like the eb70s. It keeps their laptops, tablets, phones and nintendo switches charged. It only charges at 200 watts per hour so it takes about 4 hours to fully charge. . I got tired of the wind blowing the panels down so I ended up buying the 200 watt newpowa rigid panels.
