great

For filming / photography it’s nice to have at least one set of back-up batteries & a charger in case things take longer than you planned.

Worked great for led lights. More power rhan the original battery.

A low cost solution for my Atomos Ninja Flame

Just got these and will be using them to power up the led lights I got from newer as well. On a first look Neewer has stepped up their game in presentation and quality. They arrived I placed them in the LEDs and they at full power seemed to be equivalent to the LEDs being on live power. I did after placed them for charging which took a few hours to get the green to light up. These things are massive and heavy. Which on a first impression they should last a few hours. Got 4 for now to power up 2 lights. Will get more if duration of charge is decent. Being able to have the lights portable for either indoor shooting or outdoor is a game changer.

I order this because i needed a new charger. I had two previous batteries with a different charger that recently gave out. I like this charger a lot better !!! And now i have 4 batteries, win win situation lol

I bought a small and large battery and both hold a charge for a long time. I used the small one for 3 hours without an issue!

So this is a great battery for run and gun camera rigs. This is the middle size battery, very goldilocks. The small ones are ok but they do run out somewhat quick. And the big one is heavy and in the way sometimes. This middle size powers things for a nice amount of time, and just feels better. And the charger works pretty quick.
