Two batteries are better than one, but only if they are charged and ready for action. The ProMaster Dually Charger can charge two batteries simultaneously, or just 1 if required. It is compact and convenient with a USB-A input cable that neatly stores itself in the bottom of the charger.

Since it draws power from USB sources, you can use the Dually Charger with a USB AC Adapter (not included), laptop, power bank, car charger, and more. Just be sure it meets the minimum input requirement of 2.2A.

Note:3m> Charging time is approximately 6 hours from depleted to 100% for 2 batteries charging simultaneously.
