Do I need a current converter when using my Sonicare toothbrush charger in Spain?

Yes, you will need a plug adapter for your Sonicare toothbrush charger to fit the Spanish outlets, as Spain uses Type C and Type F plugs. However, if your charger is dual voltage (usually marked as 100-240V), you won't need a voltage converter, as it can handle the 230V supply in Spain. Always check the specifications on your charger to confirm its compatibility.
