The benefits of extra batteries is a must, but not at the price original ones cost!, these are the perfect alternatives, not only can they hold their charge longer than most, they are dual charging having the versatility of usb or adapter charging! Very handy, plus the added bonus of not triggering the Sony software for being third party items, definitely recommend, worth the money 100%

Really solid batteries for my Sony A7iii and iv. Long battery life and fits my standard charger for my Sony batteries.

Like a lot of K&F Concept products, this one is a winner, particularly when you are traveling. The batteries have great capacity, maybe a little less than the original NP-FZ100, but the USB-C charge capability saves space and makes it easy to charge up a spare battery without a separate charger.

Bought several for a remote location shoot, where there was no access to power supply that could recharge the batteries. Surprised by these batteries lasted very long, had shot over 1200 with focus tracking on…
Very pleased with this product.

Love these batteries! The USB-C charging is super convenient and my Sony A1 ii with updated software didn’t give me any 3rd party battery warning when inserted, so that’s a huge plus. Would highly recommend!

More convenient than original Sony battery with the USB C socket for charging without the Sony charger. Capacity is about 80% to 93% of Sony battery for what I roughly "no-lab-measurement" estimated after using for few weeks, with the price of less than half, it might be the best value. Not sure about long term reliability for this one, my old Sony battery has lasted 3 years and is still excellent.

Very pleased with these off brand batteries. They can be charged with a usbc cord directly and I don’t get a message in the camera indicating they are not a Sony battery. Nice to eliminate extra charging devices when I travel since it can be charged directly.
