JYJZPB NP-FZ100 Battery and A7iii Battery Charger for Sony A7IV, Sony A7III, A1, Alpha A7RIII, A7R IV, A9, A9 II, A6600, A6700, Alpha 9S, A7R3 A7S III, A7 RIII Battery, 2 Pack

I bought this charger and two-battery combination for my Sony Alpha A1. It is one of those rare products that exceeded my expectations. I am an experienced wildlife photographer who travels internationally.1) It charged the two NP-FZ100-compatible batteries from their state-upon-delivery to full charge in about an hour, powered by my 9v/3A USB-C charger. This is Sony's recommended charger rating for charging the NP-FZ100 when it's inside the camera. The charging case does NOT include a USB charger...you'll have to provide your own.2) Contrary to some other comments, there IS an indication when the batteries are fully charged. There is a solid red LED for each battery when charging, and a solid green LED when charged.3) The batteries work flawlessly in my A1. There are no compatibility warnings and no startup delays or hiccups. (My current firmware is v1.20).4) The construction and appearance is fine in my opinion. No, it's not a "luxury product," but it's certainly not an embarrassment and it's rugged enough for my travel and use in the field.5) The SD card storage is for, uh, SD cards. I use CF Express Type A cards, and I can fit two of them in the storage compartment, however.I would buy this again, and would recommend it to other Sony photographers.

Reliability is everything in client work, and this product just WORKS. After a year and then some of (almost) daily use powering an A6700 in nature and small-events professional work, these batteries have performed like champs, have never power-fluctuated while in use (which causes the camera to go crazy and overheat, something that happens with my A6000’s NP50 batteries when I let the NP50’s get below thirty percent), even when I use these batteries down to twenty five percent. However, keep in mind that the average shoot on these batteries is three hours, and, starting from a freshly-charged battery at 100 percent, I will usually still have 50 or 60 percent left by the end of the shoot, so I usually have lots more left in them when I get back home and recharge them again for the next day. The charger is the batteries’ carrying case, and the whole unit can double as a USBC power bank; although, I myself would never risk uncharging my camera batteries just to charge up a phone unless I absolutely had to. But it’s nice to know you can. What more could you ask for? HUGE five-stars.

Works great but does not work as power brook.

Realistically I would give these 3.5 stars. The case is made of plastic and feels cheap. I doubt the lid will survive a fall. I also hate the design of the SD card holder. It's a nice feature but it's a royal pain in the a$$ to open and I probably won't be using it because of that. I do like that the charger has a lid though. I can throw this thing in a camera bag and won't have to worry about the batteries falling out and having to dig around my bag for them. I also like that I can use it as a battery bank in case my phone starts dying The batteries themselves are surprisingly good though. They will definitely get through a full day of moderate shooting. And at the end of the day that's the most important thing. All in all this is a good buy. I haven't seen any other chargers with a lid that can be used as a power bank.

Well to start off, I am sort of an amateur pro photographer (meaning that I do paid gigs sometimes but mostly shoot for the passion). I also hate to carry a lot of weight especially when traveling where most of my photography takes place.The only thing lacking in this product is a solar panel to charge the batteries. However to have a extra SD card storage and 2 batteries plus the capability to charge my phone in a pinch is fantastic. Consolidated more space in my small camera bag that I now use with my new Sony A7C. Batteries provided worked great and charging my phone worked great. SD storage place is a little tight and hard to handle if you have long nails but that wasn't a problem because I had a huge SD in the camera so I didn't need my extra. The materials does feel like a cheap plastic so I'm thinking it can't be tossed around or dropped a lot (shouldn't be using batteries for hockey pucks anyhow - jk). Overall a well thought out product. Will update if there is any change in it's quality.

I love this thingI have Gopro battery chargers, insta 360 battery chargers, security cam battery chargers / etc but this is my favorite one. The case / charger is simple and durable. I love that you have multiple options to charge (though I only have used usb c).Really cool
