I just received my Pecron 3600 package yesterday. I am a total novice to the whole solar generator thing and now have my work cut out for me. I think that I did my homework on this unit and this package and I hope all goes as expected. More importantly I at this point I really wanted to say a BIG THANK YOU TO Bill at Outbound Power and His Staff. They made this purchase painless and a pleasure. Their customer service is top notch and their shipping extremely fast. They followed up on the whole process from start to finish. Also in doing my due diligence I found their prices to be better that any other seller out there it makes me feel confident that if I need any help or if I have any issues Bill and his staff will be there for me. I know that any of my solar needs in the future will be coming from Outbound Power. Thank you very much. MikeR

EcoFlow 500 Watt Alternator charger

So far, it's been working flawlessly with my EcoFlow Delta 3 Plus
It doesn't seem to work well with my EcoFlow River 2 Pro; for some reason, I had to restart the Charger. Every time I tried to charge my River 2 Pro, eventually it wouldn't charge. There is a good possibility I did something wrong in the settings. I didn't buy it to Charger for the River 2 Pro anyway, so no big deal to me. So far, after two days, the EcoFlow Delta 3 Plus hasn't had any issues.

Thank you for taking the time to leave a review. We are glad to hear that it has been working flawlessly with your EcoFlow Delta 3 Plus. We apologize for the inconvenience you experienced with your EcoFlow River 2 Pro. Our team is here to assist you and make sure you are fully satisfied with our product. Please feel free to reach out to us if you need any help with the settings. We want to ensure that your experience with our charger is nothing but positive. Thank you for choosing Outbound Power.
