No charger just the cord

Many Remington shavers sold in the US are only for use with 120V. Voltage in your country may be 220V-240V. If you attempted to use a 120V charger in your 220V electrical outlet without a voltage converter, you have probably damaged the charger.
Chargers can be purchased at shaveroutlet.com. You will need your shavers model number to select the correct cord. And, you may need to use a voltage converter if the replacement you get is for use with 120V
