Maker Jamie Matthews has recently created a new supercapacitor-powered speaker that significantly enhances charging speed and playtime duration. This speaker charges remarkably fast, achieving a full charge within seconds, and offers a minimum of six hours of continuous playtime without the need for solar power. This efficiency is credited to the use of a TPA2013D1 class D amplifier, which boasts an efficiency of over 87.5% and includes a boost converter to maintain a constant output of 5.5V.
