capacitor
With a small load such as a voltmeter or LED, the remaining charge in the capacitor can last quite a bit longer than it would if connected to a load of the rated 700 mA. Some supplies might have a "bleeder" resistor across the capacitor, so that it will discharge even without a load rather than lingering.
