As a side, I have a Dell laptop that shipped with a 130W power brick. Looking at official specs, it seems to be 20V/6.5A = 130W. Given the above specs, it looks like I would only be able to draw 100W from the Insignia charger (since 140W is greater than what the laptop requests)?

Multiple port mode supports up to 100W via the first USB-C port and even claims support (in multi-port mode) for Programmable Power Supply mode up to 5A suggesting support for both 25W and 45W Super Fast Charging. The second USB-C port is limited to 30W in multiple port operation, but still supports Power Delivery profiles up to 20V (meaning it could handle laptop charging duties).
The USB-A ports are individually capable of delivering up to 12W each, but are limited to sharing 15W across both ports (so using both at the same time could deliver a very slow charge to one device).
Good luck!

If your 130W power adapter is a barrel plug, and your laptop also supports USB-C PD charging, it's possible the laptop may only support up to 60 or 100W input via USB-C. Personally I wouldn't count on a laptop pulling >100W from USB-C anyway because most devices aren't rated for >100W PD.
You can use chargers 1-4 at max power each.

Super Fast Charging is the Samsung branding for the optional Programmable Power Supply feature (which is supported by this charger). 25W SFC 1.0 requires PPS support in the range up to 11V near 3A whereas 45W SFC 2,0 requires PPS support in the range up to 11V near 5A (both operate in PPS around 10-11V so clearly the maximum current draw is lower in both cases).
This charger does claim support for for PPS in the voltage and current ranges necessary for 25W SFC 1.0 and 45W SFC 2.0 support.
Good luck!
Jon
