Duo Charger for EN-EL18, EN-EL18a, EN-EL18b, and EN-EL18c and EN-EL4-Series Rechargeable Batteries

The Watson Duo Charger accepts up to two Nikon EN-EL18, EN-EL18a, EN-EL18b, EN-EL18c, EN-EL4, and EN-EL4a type batteries and charges them sequentially. This means that the unit will charge one battery to full capacity and then automatically switch to the other battery for charging. The EN-EL4 and EN-EL4a batteries use the included battery plates when connecting them to the charger.

Charge status LEDs allow you to plug a battery into the charger and see the current estimated power percentage. Use this to quickly glance at the batteries charging and see what level your battery is charged.

The charger runs on 100-240 V AC self switching power, offering worldwide use with available adapter plugs (not included). This means you can travel and charge your batteries wherever you go.

Automatic detection circuits protect your camera batteries against damages that can occur from overheating while charging and automatically stops the charging process. These circuits also guard against the dangers of defective batteries or units that have short circuited.
