The ProCube Twin Charger from hahnel replenishes select lithium-ion batteries for Sony & Olympus DSLR, mirrorless, and point-and-shoot digital cameras via the two supplied, interchangeable contact plates. It also charges AA batteries with capacities of 700mAh or greater using a separate tray, which is also included. The unit is capable of fully charging one or two li-ion batteries in one to three hours, depending upon battery model, and four AAs with a 2500mAh capacity in about four hours - and it can even charge both types simultaneously. Additionally, the ProCube has an independent micro-chip regulated charge controller for each battery. The AA tray can be used to store the AA batteries when not in use. An LCD monitor shows the charging status of both types of batteries. The ProCube is also configured with a USB port for charging your mobile devices. Interchangeable adapter plugs for the US, Europe, and the UK are included, as is a 12VDC adapter for on-the-go charging in your vehicle. The ProCube runs on 100-240VAC via the included power supply, enabling worldwide use.
