Vemico NP-FW50 Battery Charger Kit: 2 X 1200mAh Replacement Battery with LCD USB-C Charger for Sony Cameras

I received it 2 days ago and it comes with a nice case. The enclosed, included batteries charged well, but I have yet to test its duration of power. However, as others have reported, it is a LITTLE tight when it is in place inside of the a6400. Unlike the SONY batteries, it does not easily come out once one presses down on the little tab that hold the battery inside. I'll review it now and update the review as I get more expwerience with battery "strength" As briefly discussed about photography duration of power.

Note it does not last as long as the sony batteries but it charges much much fast than them! the sony batteries take 2 hours to charge meanwhile the Vemico batteries take only 45 mins to charge. Which is amazing because they last for 2 hours filming in 24 fps, 60 fps, and 120 fps on my Sony a6400!

I bought this for the USB-C charger which works well. It charges each battery at 4W (for a 7.3Wh battery this means a charging time of ~2hrs) for a combined 8W and either slot can be used when charging only one battery. I wish the batteries clicked into place in a more obvious way but otherwise it’s great.I own one Sony battery, two Wasabi batteries and now these two Vemicos. I ran a 4K video run down test with all five batteries on my A7RII:Vemico 10:30 51%1:00 12%1:04Vemico 20:30 52%1:00 12%1:04Sony0:30 45%0:55Wasabi 10:30 03%1:00 00%1:02Wasabi 20:30 02%1:00 00%1:01The Sony battery is several years old so no surprise it died soonest. It is the most well calibrated in terms of percent remaining however. Both Vemico batteries died while reporting 9% and both Wasabi batteries died after a half hour of showing 0%.I’ve had the Wasabi batteries for a few months and several charge cycles.

I have purchased two sets of these about 18 months apart, and both have started to swell within a year of recieving them. I thought the first set may have been a fluke so i ordered a second set failed, and within 14 months they were swollen enough to make the batteries become stuck when inserted into the camera. They still work for the most part, but i can only use them in my external battery pack. The swelling issue is a real problem since it would require a professional to remove from the camera if it was fully inserted. I got lucky and felt it as I inseted it and stopped with a few MM to spare and I was able still get a hold of it.The swelling is what happens as batteries go bad. The thing is i have many other batteries i have purchased along with the genuine Sonys that were purchased years before these that have suffered no such issues to date.I would pass on these even though i like the color since it makes them easy to find in your bag.

Ok so most might think, they are just batteries, like any other company, whats so special right? Thats the same I thought. Now dont get me wrong, they are good batteries. They are not reinventing camera power. Which is fine, but what makes me love these is flat out the orange color. Some might think, who cares about a color, its inside your camera. You never even see it. Sorry sir, but i must tell you that you are wrong. These have already saved me a few times from losing them in a hot mess of camera equipment in my bag that is everything BLACK! I can spot these right away on my desk, in my bag or anywhere I go. If i dont know which battery is dead, with these, I do. I no longer guess which black battery I just killed.Sorry to ramble on but something very small like a color has changed the way I want stuff now. So if you second guess why an orange battery, get these, you will not regret it.

Ordered these just a few months ago, and they have been working fine in my Sony a6400, but... yesterday it took me three hours to get one of these batteries out of my camera. Fortunately I got it out, shaking it carefully for that entire amount of time, but no mas. Spend the extra money and get batteries directly from Sony, or some other brand, but definitely not these, otherwise you might damage your camera. This should definitely not be happening after just a few months of use. These batteries have been incredibly tight since I first got them, but I guess after just a few months, they are swelling. No bueno. Just fyi... and my biggest issue... I reached out to Vemico, and no response. Zero. That's why I'm leaving this information here, and so be careful. Protect your camera.

A nice set of batteries (Love the color), charger for two batteries, a USB-C - USB cable for charger, very nice pouch or case, and the batteries are protected by an individually plastic case. First impression: very nice set, very well done. Placed them to charge for around 10 minutes, then they were fully charged and we were ready to turn on our Sony Camera.They worked well, great option to replace old set of batteries, and we can say: This is a great deal for the price!

Sony RX 10ivThe camera takes an NP-FW50 batteryIt is a great-looking product! The case that keeps everything together would be amazing for travel. (2 stars) I was very pleased and excited to try it but when I went to put the battery in the camera the frustration began! According to the posting, these are the same size and are a replacement for the NP-FW50 battery. I was able to insert the battery in although very snug and it did register and show the battery was in and charged, it was not so snug that I thought there was going to be this huge problem but I was wrong. Trying to get it out was awful! When I push the retainer clip the battery did not budge. It was stuck and because it was in the compartment I could not get it out of the "hole". Truthfully, I began to panic a bit. It is at $1700 camera and now a battery was stuck and not budging. I finally had to hold my breath and use a knife and pry it out of the compartment while trying to keep the retainer clip out of the way. I was finally able to get the battery out! With great disappointment, I must send it back. It looks great appeared to be great quality but the measurements have to be wrong!
