BLUETTI AC70P Portable Power Station | 1000W 864Wh, Everyday Use

Works as advertised and delivers the promised capacity. The AC section is very well-designed, providing full voltage with a good sine wave over a wide range of power with negligible voltage sag. Very good performance out of the DC side as well, and the unit recharges remarkably fast. Although there are no user-servicable parts inside, I opened it up to see how it was built and the construction and parts quality are outstanding. This thing is built to last. Minor caveats: The unit is a bit heavy for its capacity, and don't be fooled into thinking it's water/rain resistant by the outlet protectors, because there are large vents on either side that water can easily penetrate, which would be bad. Finally, there was some very minor harmonic distortion in the AC output when under reactive loads such as motors, but this is not a big concern for any real-world application.
