Energizer introduces the Energizer DUO, a charger that meets the needs of the wired and wireless. The DUO charges two AA or AAA rechargeable batteries (NiMH) in as little as two hours for AAA's and as little as five hours for AA's via a computer's USB port or a standard wall outlet, giving users the flexibility to choose how they want to recharge their NiMH batteries for power hungry devices. In addition, the Energizer DUO has a customizable computer interface that monitors charging progress on your computer screen.
