An iontophoresis system comprises a power supply apparatusnhaving a chargeable battery, a positive output terminal, annegative output terminal and a positive charge terminal, and anpreparation having input terminals connected to output terminalsnof the power supply apparatus. The negative output terminal ofnthe power supply apparatus also serves as a negative chargenterminal for charging the battery. During charging, thenpreparation is removed, and terminals of a charger are connectednto terminals of the power supply apparatus, respectively. Thenpower supply apparatus comprises a power supply monitoring portionnwhich gives a warning when a battery voltage becomes anpredetermined value or lower and a control portion for controllingna power supply state from the output terminal. |
