ISDT NP-FZ100 NP-FW50 NP-BX1 Camera Battery Charger Set for Sony Batteries Cyber-Shot DSC-RX100, DSC-RX100 II, DSC-RX100M II, DSC-RX100 III, DSC-RX100 V, DSC-RX100 IV, HDR-CX405

Does what it says and charges my NP-FZ100 (A7RIII) and NP-FW50 (A7RII), one charger for both types makes things so much easier and tidier. The charging voltage and current, as well as, capacity information is also nice to have!

I have owned this charger for 11 months. I have put it through many dozens of battery charging cycles, and so far, it has performed flawlessly. I happen to have Sony cameras accepting all three types of supported batteries: NP-BX1, NP-FW50, NP-FZ100. I find it convenient that this device allows me to replenish two batteries simultaneously, plus I can also mix and match different types! This charger sports a color LCD, which is bright and easy to read. With a simple button push operation, you can see the current charging info: voltage, resistance, etc., it puts out to the battery, but most important for me: it shows the battery health rating. I do appreciate this last feature. I find it super helpful to know when to replace an aging battery and/or not get caught with a dead camera while out there shooting. As for the downsides... The unit comes with a USB-C to USB A cable in the box. If you have a more modern USB-C charger, you will need to invest in a separate USB-C to USB-C cable. That was not a big deal for me, but I feel it has to be pointed out. One more thing, I can not seem to make it work with QC chargers. I am not sure which device is at fault here, but a couple of QC 3 rated chargers I have and tried do not make any difference at all ¯\_(ツ)_/¯ Having said that, I am pretty happy with my purchase and would highly recommend every serious Sony camera owner to give it a try. Pros: * Works equally well charging three types of Sony batteries: NP-BX1, NP-FW50, NP-FZ100 * Simultaneous and independent dual charging * Modern, bright display, showing a bunch of helpful info, including battery health rating * Easy, straightforward operations * Audible beep signal confirming button presses, battery insertion/removal, and marking the end of charging cycle Cons: * Comes with USB-C to USB A cable only * QC might not be working as expected

Chargers aren’t something I generally get excited about, but I have a few cheap USB chargers as well as the OEM Sony wall charger for my Sony Z batteries and none compare to this one. It’s very compact, has a nice screen (even comes with a screen protector for it), gives me info about the battery’s health, and above all charges 2 batteries simultaneously and FAST! I paired it with the recommended 18w QC 3.0 charger (not included, but cheap) and it’s by far the fastest charger I have when used in quick mode. Much faster and cheaper than the OEM Sony wall charger that came with my A9. If you’re looking at this charger, just buy it... it’s great!

Very cool features, love that it tells you the battery health. Only issue is that sometimes it will only charge the battery to 90%. This was more of an issue in the beginning, it seems to have gotten better at getting to 98% now.

I really wanted to like this unit since it can charge both my A73 and RX100 batteries however after a grand total of about 6 months it went wonky. Batteries with 90% charge are reported as having 1% and simply won't charge past that. I tried several batteries with the same result so it's not the batteries. Also those same batteries charge perfectly on the supplied Sony AC charger. So it goes, I should have known it was junk but wanted to believe it'd last for at least a few years.
