So, you have a Canon 70D and you wanted more power. So, you bought the battery grip and three extra batteries; two for the grip, and a couple of spares. But, that dinky little charger that comes with the 70D only charges one battery at a time! You are shooting a wedding video and you are going through batteries like they are going out of style. How can you keep up? You get a dual charger, that's how! Yes. This charger is awesome. You have a clear readout of the charge level for each battery. You can choose the charging speed to kick it in a jam. It has the ability to be used with standard voltage of a wall outlet, as well as an accessory port in a car if you are on site. it's lightweight, and takes up very little room. The build feels unpolished, but not low quality. The charging bays use inserts, but this provides the maker with more options than building a single unit for each battery type. The LCD is of average quality. Overall, this is a great charger for the price. It works on both my Canon and Panasonic batteries. I would easily recommend this charger.
