K&F CONCEPT NP-F550 Battery and Charger Kit, Compatible with Sony NP-F550, F570, F750, F770, F930, F950, F960, and F970, LED Lights, Monitors, and Camera Sliders

Love K&F products and this one doesn't disappoint, does exactly what it says on the tin, comes with two USB ports including USB C so you can get quite a fast charge. Is quite thin and easy to store so ideal for chucking in the camera bag on longer trips, and if like me you've got mulitple battery types one USB lead will fit all of them. I'd love to see a version which displays the percentage of charge as this would help when just generally checking battery state. Good quality, great value for money and easy to use.

Love these batteries, they last for quite a long time under constant use. Charge time is pretty good on them too

Great alternative batteries Last slight shorter than my Sony battery but negligible amount. 2 spares and a charger is more than enough for my needs, excellent quality no issues and have been using them for about a year Charge in a decent amount of time and great value for money Totally recommend

You'll Always have two fully charged batteries at hand for a long day snapping or video .

My intention is to use the K&F Concept NP-F550 Battery and Charger Kit to provide a higher capacity battery for my camera monitor, without adding any noticeable weight increase to the whole package. But, for fun, I connected both batteries to one of my 45w LED panel lights, and ran it at 30% output to see how long these small batteries might last, slightly under 2 hours later, I found out! The batteries were slightly warm from that load, but charged up normally afterward, so no damage done. They should run my monitor for over 2 hours continuous, so the pair, with the original battery, should set me up for my next weekend away with camera quite nicely. The charger unit doesn't show the state of charge of the batteries, showing a red LED when charging, changing to a green one when charging is complete. It is not a particularly fast charger, so several hours are needed to go from exhausted to full. No complaints from me, they will power my monitor beautifully, and I know I can drive a LED panel, at a push, if needed.

I have a small collection of NPF batteries and chargers, Some are from unknown brands and some are from branded suppliers, like these ones. For expensive equipment I tend to only trust the branded batteries as I know people who have had major issues in the past with battery issues. K&F is a brand I trust as I've used their stands and filters for years. These batteries perform exactly as expected and the charger works fine. It charges no faster or slower than my existing chargers, but it is nice and slimline and therefore is easy to pack away. The batteries are NPF550 and work brilliantly, I've also used this charger to charge my hefty NPF-950 and it handled those fine too. The charger and battery seems well constructed and not bulging or flexing anywhere it shouldn't. Definitely a great option if you need a pair of NPF-550 batteries, these are the ideal size I find for field monitors and work a charm on mine.

Die Akkus liefern eine ähnliche Laufzeit wie der originale Akku. Die Ladeschale ist komfortabel, schnell und mit USB C zeitgemäß. Habe noch weitere Akkus und Ladegeräte des Herstellers im Einsatz und bin äußerst zufrieden.

This battery charger works perfectly to charge all of my NP batteries. I use this to charge multiple different kinds of NP batteries and they all charge perfectly. My only complaint would be that some batteries need to be carefully inserted as you can bend the gold pins on the charger if you're not careful. For the value, it's a great charger to keep in your bag in case you need it on the go. It's nice that you could charge it with the USBC, you also have the option to charge it with the older USB connector.

With a 700mA discharge current, the battery tested at 2140, which is in line with the advertised capacity. Usually, we see a larger gap than this. The NP-F970s from K&F were also very good. The charger consumes 5W for each battery, or 7W for a single battery, the charge is on the slow side. For 15Wh batteries, this is a reasonable speed. Charging LED's are inverted compared to battery position. This is not the best charger, but this is accurately what is described.

Corrispondente a descrizione e utile allo scopo

Malgré un temps de recharge long (environ 4h), le prix abordable en fait un indispensable!
