Love this charger with batteries set; put them to charge & ready for use

The media could not be loaded. This arrived packed with care, arrived on time, and the batteries charged with not issues. I've used them to power my external portable light for two events thus far. The battery life did not show any issues, having used them for a five-hour event and a two-hour event.

It is very handy with the 4 slots to prepare for your projects.. But Batteries die very quickly when no in use

For business.

This is one of the best kits you can get that I have seen. The NP-F550 is a very common battery in the photography and videography world. It is an excellent choice, when you want to keep the weight down and offers sufficient run times for monitors, lights and recorders.I really like to use these for my camera mounted monitors and recorders. For a basic monitor with average nit brightness of about 600, I was able to get almost 2 hrs of battery time out of it. For my 2200 nit brightness monitor on max brightness, I got about an hour and fifteen minutes before the battery died. The same was so with my Atomos Ninja V. But these times will possibly vary depending on the environment you work in as temperatures have a big effect on battery life.The charger is absolutely perfect. It is equipped with four bays and allows you to charge more batteries and faster than your typical single or dual battery chargers. The charger comes with a traditional AC plug, which I love. I do not have to keep buying power adapters or share them over the many usb only style chargers on the market and in my battery storage area.This is a great kit that offers good batteries and an awesome charger at a steal.

Using this to charge up some extra NP style batteries I have .. And I do like it. Im glad it comes with a Standard have a bunch of power cords so in the field I'll have the ability to use them without any funky Wall wart power supply. The included batteries might not get much use (unless I can get a 5 inch monitor for my gimbal) but for my other batteries .. TOTALLY this charger will get used. Can never have enough batteries on shoot day . Especially when you have multiple setups and you can have a central battery charging station. This charger will be one of my main chargers on shoot days. And will join a few other multi battery chargers to help make my day run Smoother.Pros: Standard 2 prong power cableCharge 4 at a time4 smaller batteries for Gimbal usageCons: Wish it had come with NP970 as those get used more.

I don't actually have a camera that accepts these batteries but more and more of my accessories use these.Took it out of the packaging and threw four included batteries into the charger then plugged it up for the night. The LEDs started off red and ended green in the morning.My Raleno LED panel has a spot for 2 of these so I plugged up one first. Turns out it actually needs the second battery slotted so I drop the other one in too. The LED panel lights up and goes to max brightness (to my eyes' dismay) on battery power. Great! I happen to have 2 LED panels so these 4 batteries and charge block will basically be mated permanently. The LED panels use as much or more energy than the Sony camera's the batteries are compatible with so I'm not too concerned about battery life, especially when I could just wire up the lights and batteries. My workflow isn't so sensitive that a couple depleted batteries gets in the way.

Batteries themself perform well enough definitely die relatively fast. Quality is cheap plastic, actual port and cable became finicky then stopped working. Now it says that the “product support window has closed”.**Edit** Changed to four stars. Customer service was responsive and sent an entire new unit. Still a little finicky but works and 4 extra batteries now. Thanks.
