Charges good. Great f you have a bunch of NPF batteries.

It charges perfect! It takes longer when charging all 4 batteries at once but it gets the job done.

good big charger

I tested this charging dock with third party batteries by Artman and two out of the four charging docks wouldn't hold the battery securely. I had to press the battery firmly several times to trigger the indicator light. I then tested with native Sony batteries and had no problem with the connection at all. Takeaway: Be mindful if using with third party batteries.

Works as expected and fast charges my packs! Good investment. I’ve charged 3 batteries simultaneously. Perfect for what I need

Only beef is quality of construction. Connections pins for one charge slot is lose and will not stay in. Another pin is off angle causing battery to not fully clip in play unless taped in. Does it charge ? Well yes it does, no complaint there.

Nice charger for the money. Fits our needs and doea the job. For pros, recommend the standard wall plug over USB, for speed.

As a professional videographer we often go through 15 to 20 of the Sony NP-series batteries in one wedding, I can put all the batteries on charge now and they all fully charge. Some of the other charges for some reason only seem to charge a couple of our big batteries to 3 bars out of four where as these chargers charge it completely. I'm very very happy with our purchase and they work great. We have five of them now so we can literally charge 20 batteries at once, a full days shoot ready to go again for the next day!
