Windowspray: Good for you! After waiting 2 months and realizing they don't fill orders on a first come first serve basis, I cancelled my order. Estimated shipping dates on their website are a joke. Found their Customer Service(China Based) to be slow and dishonest. Instead I got the Jackery 500 during the anniversary sale for $424. If you watch Hobotechs review of the V2 version of the Jackery, despite being advertised at 518wh, he got 553 useable watt hours in his tests, 120wh more than the AC50S, implying that there is nearly a 600wh battery in this thing. The extra charge cycles of the Bluetti aren't a big deal for me. Jackery support is USA based, polite and responsive. I ordered online on a Monday, and received it that Friday. I have an AC100 which is OK, but I would not buy another Bluetti again.
