The Power of The Sun Charging My Business!!

I wanted to be sure I had more than enough power going into my Delta Pro and Extra Pro Battery, especially if I am on the move or need to power my 3D printers for an outdoor event. Leaving the panel out in prime sunlight made it charge the batteries as I was 3D Printing. This means I was 3D Printing with ZERO CARBON EMISION! That's amazing!! I'm seriously considering making my whole business run on ECOFLOW Batteries and Solar Panels from this one experience alone.

EcoFlow 400W Portable Solar Panel

This pane has been my go to panel when charging my devices. i average around 375 t9 384 watts which is very good. i now own three of these panels and i would highly recommend them to anyone looking for a large foldable panel with this much solar output. Do not just take my word for it try one and see why I love this panel so much.

Excellent Foldable Solar Panels & customer support

I am very impressed with the Echoflow foldable solar panels. Well made, meets or exceed all specs. I like that the panels are built for the Echflo pro product and I don't have to gerry-rig 3rd party solutions..Be aware that they are soldi built which makes them heavier than other similar panels.....just goes with the territory if you want quality..........In-addition.....I am always impressed with the customer support EchoFlow provides....I know I can always get an answer to my questions either through customer support line or the EcoFlow Delta Series Group, face book page ..I highly recommend all of the Echflow product and anxiously waiting for new products that can augment my home power needs..... thank you very much!
