Recharging works very effectively on the device. It can be seen clearly on the scale how much the batteries are charged. Thus one verhinert that they were not enough charged. In addition, you can unload with a button which keeps the battery alive longer. Downside is the very bright display. If one battery at night invites, then best not in the bedroom, unless you want a blue light sleep ;-)
The battery itself with 2,700 mAh are the delusional sense. I operate in multiple camera flashes for a SLR. Usually I get a half hour far with burlap and batteries. Here I was not even at the borders of the battery after a one hour shoot. Respect!
