Humongous capacitors for cell phones and other applications

Other Parts Discussed in Thread: TPA2013D1

Hello,

I worked with a capacitor vendor to test their capacitor (0.5 Farad / 5V) with our boosted class-D amplifier, TPA2013D1. It greatly improves the audio experience since you have essentially unlimited current available.

My question to the community - what are you feelings about this technology?

Over the weekend, I saw a flashlight designed for the law-enforcement market that uses capacitors instead of batteries. Their ad claimed they could recharge in 90 seconds.
