It's nifty that it can charge 8 batteries at the same time but you will rarely need this many. At least I don't. What is more worrying to me is that this brand is unknown to me, not that I am an expert but still, also there is no mention of built-in protections. That last thing scares me. Some of the bigger batteries will have to be charged over night and I don't think I'd be willing to trust this device not to burn your house down.
In my opinion getting Opus BT-C3100 is a smarter choice. They are well known and tested, offer more functionality (testing, discharging, refreshing, etc.), can charge up to 2A (on slot 1 and 4, 1A on all).
Am not claiming Klarus is a bad brand or this charger is not good, but provided information is making me skeptical.
glennacThat's good to know. Like I said, I am no expert with this, just unfamiliar with this manufacturer. Still, I'd like to see some details regarding protections which are in place.
To be fair, as a photographer, I often have 2-3 sets of four batteries to charge. But overall the lack of power per slot would concern me with this product.
