Supercapacitors are also known as ultracapacitors or double-layer capacitors. The key difference between supercapacitors and regular capacitors is capacitance. That just means that supercapacitors can store a much larger electric field than regular capacitors. In this diagram, you can see another major difference when it comes to supercapacitors.

The charging and discharging time of the supercapacitor depends on the time constant (τ), which is a function of the ESR of the supercapacitor (R ESR), charging circuit series resistance (R), and supercapacitor capacitance (C) as in Eq. (4), [6]. (4) τ = Total Resistance × Capacitance = R ESR + R C
Supercapacitors, bridging conventional capacitors and batteries, promise efficient energy storage. Yet, challenges hamper widespread adoption. This review assesses energy density limits, costs, materials, and scalability barriers.
Therefore your result is insufficient charge time with a battery but ok with a PS. However high ESR from clone supercaps with ESR>1 Ohm will cause significant Ohm''s Law voltage drop even with 0.15A current reducing your storage time significantly. These are common oversights and the reason why Maxwell Ultracap test specs are so detailed.

A load was applied to the "Kilowatt Labs supercapacitor module" until it was "flat" (the volt meter read 0 volts). When the load was then disconnected, the output voltage rose again to approx 40V. We both know this would not be possible if the module only contained capacitors & contained no DC-DC inverters (which Arvio claim is the case).
