I have 6 power stations.
I have - 1 x AC200P, 3 x AC180, 1 & when delivered a 2nd AC70. Have had no issue with any of them. I also won a X20 in a Forum comp. It, unfortunately will not power our 2 x Dell laptops. However, we still have 3 older HP laptops that it does power. Got heaps of assistance from Bluetti Admin on the Forum along with other users. It's the laptop not the X20.
