Using the Powerextra, I would clearly have to swap batteries earlier. I'd be nervously looking at the meter and fretting during groups and couples portraits about the remaining capacity. Also, it has been confirmed that counterfeits with a decreased battery capacity compared to the genuine batteries are being distributed to the market. The use of counterfeit batteries implies a fire or explosion hazard. One of the biggest criticisms of early Sony mirrorless cameras was the fact the NP-FW50 battery did not have enough capacity for professional wedding photographers and videographers. I remember the early days when we filmed weddings using the Sony A6300 & A6500's. We would literally carry a bag full of NP-FW50 batteries and constantly be stressing over which camera needed to have a new battery soon.

After the first test, I realised a couple of things which limited the usefulness of my observations. These were: Lithium ion technology so there is no memory effect, you can recharge it at any point without having to discharge it first.

We're very easy to find, our London store is just off Oxford Street between Oxford Circus station and Tottenham Court Road station. The Essex shop is located in High Chelmer Shopping Centre, just off the High Street in Chelmsford.The Stevenage shop is located in the Old Town, in the old Post Office with parking outside It has been confirmed that when attached and used with the camera, counterfeit batteries can lead to issues such as:

One option I just thought of is to use the original Sony battery you got with the camera and have one PowerExtra as the second battery. That could be a happy compromise if you really want to save money. For Wedding Videographers The SmallRig NP-FZ100 is one of the best third-party replacements for the Sony’s NP-FZ100 that I have looked at, not only matching but bettering the capacity. The 2400mAh capacity, slightly higher than the Sony original, helps to extend shooting capabilities, allowing a few extra shots or minutes of video. For a full day of filming, we used to average out at going through three NP-FZ100's per Sony A7iii. With 25% less power per battery, we'd have to now use 4 batteries. An extra change on paper. But the shorter the battery life is, the more I would be stressing about the time to change. Visit us and you'll always find a friendly welcome. Our policy is to treat our customers as we would like to be treated ourselves, a simple ideal that we try hard to live up to. Battery life was massively improved when Sony released the A9 with the new NP-FZ100. Since then this has become the new battery for all modern Sony mirrorless cameras.

The SmallRig NP-FZ100 is a bit different from many of the other third-party batties that are available for Sony cameras. It’s not only a replacement option for the original but also improves the quality of use and capacity of Sony’s own. This replacement battery is designed to work seamlessly with Sony cameras, employing the same physical specs to ensure a snug fit.

My wife has already said she won't be using the Powerextra's for that reason. We'd much rather just pay more and have longer battery life. The Direct USB Type-C charging is the real winning and a feature that genuinely streamlines workflow. No more separate chargers to worry about, and it slots right into the existing charging ecosystem that most modern tech gadgets, even Apple are moving toward, actually have to move toward. Simply plug it into your power bank or laptop, and you’re ready to go. Next I inserted one battery into each A7s3. To make things as fair as possible, I used the same settings on both cameras, same memory card without any lenses attached. Of course I was not expecting the Powerextra battery to be anywhere near 2500mAh. Let's just say over the years I've learned that third party manufacturers can be 'generous' with their estimates. Be that battery capacity or light emitted from a flash, I've learned to always take these figures with a pinch of salt! Given the fact the Sony was only showing 87%, I figured I'd start the test anyway. Since many Sony owners do not use the original Sony BC-QZ1 charger, instead using third party chargers. The Sony A7iii, doesn't even include a dedicated charger! (I assume to keep costs down). I wanted to see what happened. Would the Sony still win? Or would the Powerextra be victorious?After fully charging both batteries using the Sony charger, I repeated the test. This time noting down the times each dropped 10% charge. Here are the results.
