Great price on Delta 3 with solar panels!

found this at a really great price! I've been wanting the Delta 3 with a solar panel. I priced this for weeks on Amazon and left the tab open. When I sought to purchase this set, it had gone up suddenly from 800.00 to nearly $1200. I believe it was the "interest shown" that caused the price spike. Checked here and Walmart had it at the right price, so I bought it here! I may never have to use it, but it sure is good to know that If there's a blackout in my area, I'll have both the delta and this delta 3 for backup. Thanks Walmart!

Solar panels arrived first in perfect condition. The EcoFlow generating storage battery arrived also in perfect working order. Charged 30% on arrival but I plugged it in and got fully charged in less than 1 hour. Tested on various appliances: TV, air fryer, washing machine (couldn't handle spin cycle surge), and lights. Took awhile to get charge down to 50% at which time I hooked it up to solar panels and in a couple hours of sunshine had it back up to 99%. Very pleased with my purchase.
