Tried getting 5A out of it by installing a fatter power cord with direct soldering. It still maxed out at 4.2A. The reason is the maximum power is 50W. Looking at the Ruideng showed the power maxing out at 55W. The same charger is marketed as 50W - 90W, depending on the seller.


Having run the Ruidengs at 5A so many times to test halogen lights, inverters, & battery chargers, it was definitely worth getting the 5A version instead of the 3A, though the bluetooth & USB options were worthless. The heatsink with no fan hits 41C at 50W. It's also proven useful to have the full Watt indicator of the default firmware instead of flashing minimal firmware on it.

Watched it in a manely empty IMAX theater. The audience was 1/2 of 1% of the usual audience size. When the flying part ended, some left. There was no-one under 50. For someone following the space program long before SpaceX, it was the same as many other documentaries we watched for the last 40 years. For those who just discovered the space program because of SpaceX, it should be exciting.


The sharper footage was manely confined to the liftoff, while the rest was the familiar 16mm & TV footage shown in split screens. They didn't use the slow scan footage of the 1st step but instead showed the view looking down from the window. Buzz's egress was the only thing shown in slow scan footage.


The 65mm footage was much smoother than expected, while lens aberrations of the time were greatly magnified on the big screen. The 16mm footage was much grainier than we've seen it before. Those of us who have viewed 8k scans of 35mm are familiar with how grainy film is at that resolution, so it's definitely not a cinematic effect.


The only revelation for the lion kingdom was new footage Buzz took of a solar eclipse from the capsule. He couldn't hold the camera steady enough to capture the corona, but he described it.

After the ordeal of driving 2000 miles & camping overnight to see 2 minutes of solar eclipse, masses of tourists are just going to take a rocket flight to the right place in space to see a solar eclipse, any time they want.
