[2 to 4 Hours] It works great 10/10 recommend it.

[Sony NP-FZ100] Got these after-market Neewer batteries for B&H's 200 dollar, used Sony a6000 which I finally made the plunge to get. I was going on hope beyond hope that a condition 8 camera would even work, let alone worry if it came with any batteries, and I didn't want to spend as much for two batteries as the camera: so this price point was exactly spot on. Too bad I can't write a review for the camera, but these solid, sleek, Neewer batteries made this nice but used camera feel new. The batteries charged up in an efficient amount of time (about two hours), and they powered the camera without a hiccup. I just had a three hour wildlife shoot out in the field, and I never needed to change batteries. Do note that I have a habit of flipping the camera off between hiking away to the next location, so I'm sure that helped. In short: great batteries & a great price without any quality issues. The charger's LED display is easy to read, as well. Kit includes everything you need to keep your camera rolling: two batteries, a charger, and the charging cord. Even the box Neewer designed for it looks premium. Nice product.

[Lithium-Ion] Ordering and delivery easy and quick as usual. Good charging rate. Descent price.

[Lithium-Ion] One of the more advanced chargers I own.
I have the genuine Sony , Watson and then I had the jupio (which I was very unhappy with)

This charger gives some insight into the battery performance the others don't allowing both USB c in and a built in USB cord.

I'm pretty stoked about it this far and at the price point I'm waiting to see something go wrong with it

[Simultaneous] I have a Sony A7IV and had a A7III before that so I have had a few different types of aftermarket brands to supplement the extra Sony batteries for this camera. I really like these the best so far. I would recommend them based on what I have seen. The big question with the aftermarket batteries for me has been how long they live. The Sony batteries have been better let's hope these work out. Give them a try!

[Sony NP-FZ100] great battery

[Sony NP-FZ100] A very nice charger at a great price. Charges well but not quickly. Nothing better at this price point!

[LED] This is the best way to carry and charge my batteries. It is easy to unplug and throw in my bag, I can just put it right back when I get home. Keeping a spare sd card in the compartment will help in a pinch. I have had no problems with the third party batteries, they work entirely well (maybe they last slightly less than the sony batteries) but I bought this product for the case.

[Sony NP-FZ100] I upgraded my older Watson (non USB-C) charger to this to try to eliminate the weakness of that attachment. The SmaiiRig seems to be a bit faster in it's charging ability than it's predicessor.

[2 to 4 Hours] Lots of cool features for a charger. The main one being able to plug the battery in without power and it will illuminate battery life.
