[2] I bought 2 of these to go along with the two that came with my A7RII, and they charge, work, fit, read, and power perfectly. I've been using them for around half a year now and they've held up great (shooting 3-4 times a week) also I'm not sure if it's just in my head but they seem to last a hair longer than the OE Sony batteries.

[7.4 VDC] I haven't had any problems. Powers my nano II control handle. Power indicators on the charger are a nice bonus, though other reviews say they are unreliable, I haven't experienced that.

[Lithium-Ion] A bit quick to judge but they charged properly and give me adequate time for the money. We'll see in the long run.

[Sony NP-FW50] Makes my life easier for shoots knowing we always have batteries charging and ready to roll

[1x USB-C Input] 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.

[1x USB-C Input] I purchased a Sony NEX5 and this extra battery before going on a 2 week trip to Europe. This extra battery proved not only convinent but performed as well as the Sony battery. No probles at all to date.

[0.455 lb] At a much lower cost than the Sony equivalent battery this battery provides equal performance. I'm very pleased with this purchase.

[1x USB-C Input] The batteries and charger are both great quality. No issues. Charging does take a long time (a few hours) but the batteries hold that charge well and hasn't been an issue.

[LED] Battery fits camera as well as original. Main differences noted were that mA capacity of Power-2000 battery at 1500mA was higher and charge current of PT-59 700mA charger output was also much higher than the Sony 280mA charger for its 1080 ma battery. From some basic solar panel battery charging experience, I decided to purchased matching charger. Batteries charges in under 2 hours from low 40% level to 100%. Have not used Sony charger for these batteries, nor used this charger for the Sony battery due to current differences. Also like, and wanted, the 12VDC car power cord feature for camping and other outdoor excursions away from 115VAC. So far this choice has worked well together.

[Sony NP-FW50] 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.
