If you're like me you probably have a half dozen different battery types hanging around. Having so many different cameras and different accessories adds up to a mess of battery chargers. So here's an unboxing of the Volta Dual Battery Charger which not only can charge two batteries but can also charge different types of batteries simply by swapping the charging plates.
The Volta Dual Battery Charger features interchangeable battery plates, an LCD display, and it has smart charging capabilities.
Interchangable battery plates make this charger a perfect solution for charging many types of li-ion batteries for both video cameras and DSLRs. The unit also has a USB input on its side, so you can charge a mobile device at the same time.
The charger will auto-detect the battery voltage to prevent overcharging, and a backlit LCD display shows you the current charge status. You also have the ability for a high current charging mode that will charge your batteries faster, helping to ensure that you are never stranded with a dead battery.
A few years back, there was a few other brand dual chargers with interchangeable plates such as the Pearstone. That has since been discontinued. You may still be able to find the Watson Dual Battery Charger, but that will start at around $80 Dollars (found here).
