So it's charger and compact since it folds for storage. It's really well designed. Moreover once supported, unfolded, a LED indicator shows the charge level in the battery (red charging, green is finished).
I like being able to charge both 2 AAA batteries and 2 AA batteries. Who does not remember the older chargers for which we had always four recharge the batteries. Here you can charge two batteries and even better four batteries which 2 are not the same size.
I tested this charger in the office. For indeed, I have a mouse with batteries discharge all the time. While there, the time my lunch break, about an hour, and although the two batteries have been recharged. I have been blown away. And in addition, safety is you will have no problem batteries that are overloaded. Charging stops.
I almost regret that we can not load a single cell and that we should consistently put two. For this, we must invest in a slightly more expensive product from the same brand that will charge your batteries in 15 minutes. But that's no big deal, this charger perfectly fulfills its function. I no longer have to wait four hours or five hours but it is loaded. It's great. Obviously, the batteries still fail when it is no charged ahead
