Abstract
A liquid fuel cell unit which outputs a first voltage, a boosting circuit which boosts the first voltage output from the liquid fuel cell unit, and outputs a boosted second voltage to an electronic apparatus, and a first control circuit are included. The first control circuit compares the first voltage output from the liquid fuel cell unit with a preset first threshold voltage, and controls the boosting circuit in accordance with the comparison result such that the first voltage does not fall below the first threshold voltage, or the first voltage holds the first threshold voltage or more.
