SMALLRIG 10500mAh Replacement Battery for Sony NP-F970 F750 F550, PD 36W USB-C 3.5H Fast Charging, Camera Battery with OLED Screen for Camera, Monitor, LED Video Light, Camcorder, Green - 4577

Great company and exactly what I needed.

I splashed out a little more than usual for these NPF batteries and I'm so glad I did. I've been getting near enough a full day off one battery on my Portkeys monitor where usually the cheaper batteries would be 3 in a day!The handy battery percentage is a nice touch too! highly recommend.

I've always had issues with third party NP-F batteries and this has been fixed with these ones from Smallrig. No intermittent connections, accepts a 36w charger so it full in next to no time and has connections to provide a charge to other devices over USB.It's also handy to have an on screen charge gauge too.I've genuinely had issues with the hotshoes supplied by Dedolight for NP-F batteries. It's not Dedo's fault, just that they are exacting in the fit and third party manufacturers tend not to be so accurate or forgiving. This solved my problem and was worth the price seeing as it's so hard to get official Sony batteries and that they lack any of the functionality of these ones.

When the 'SMALLRIG NP-F970 10500mAh Replacement Battery for Sony NP-F970 F750 F550, PD 36W' arrived for me to test I actually felt a bit guilty. The fact is that I don't have a camera that accepts these batteries. Much to my delight - my lighting ring does work with these so I can feel a little better that this is not just a very expensive and decent quality power bank.The quality of the packaging and the contents is just excellent. It is evident from just removing this from its nest that this is quite a bit more than a basic power bank. The green and orange is discreet enough not to draw too much attention.Charging from the initial 67% it arrived with was completed in under 2 hours via my high power USB-C charger. The LED display is extremely clear and once charged can be activated via the button just below the screen.In use it is absolutely seamless, charging via either of the USB ports gives a very decent charge rate (as expected) in use on my ring light it was also flawless. The fit to the adapter plate is like butter, I would imagine that this is similar for a Sony camera.At a price of £79.90 this is not cheap, however when you have paid several hundred or thousand pounds for your camera it's probably worth the extra.

PROS-I love the LED indicating level of charge, so useful-measured it taking a charge at 35.5W (from a PD100W charger, with 240W capable cables)-measured it supplying 35W to my highest draw device (a video light that will take 100W of charging power)-textured sides mean a better grip-USB-C in/out, plus USB-A outCONS-steps down to a total 54W of discharge power when outputting via USB-C and USB-A simultaneously (not a major con, this is not a huge step down from the USB-C 36W + USB-A 27W that they can do individually).NOTES-I use these batteries in several different ways (they have become such a standard), I’m very happy to have this one (especially as the USB outputs will be so handy to have available)MY STAR RATINGS:1* substandard, mostly cons2** barely acceptable, cons outweigh the pros3*** meets the basic requirements, cons balance the pros4**** good product, pros outweigh the cons5***** exceptional, all (or almost all) pros

I have been very impressed by this, straight out of the box I could see and feel the build quality and design were both spot on, so I was able to give it a test run straight away. It exceeded all my expectations and performed admirably on my latest shoot. Easy to store and recharge Via USB-C All in all a good piece of equipment that I totally reccomend.
