Powerextra2 Pack Replacement NP-FW50 Battery & Smart LCD Display Dual Channel Charger for Sony Alpha a6500, a6300, a6000, a7, a7s, a5100, a5000, a7r, a7 ii Cameras

These batteries replace the Sony NP-FW50 and work exactly like the factory unit - at a fraction of the cost. What's not to love? The charging speed is perfectly adequate. Perfect because anything faster I'd be worried about the lifespan. The charger is compact and comes with a USB attached, with an LED indicator. I couldn't be happier with the purchase!

Works perfect. I like the charge display.

The charger works fine. However, it came with one bad battery. Wow, the seller saw my previous comment and immediately sent me a whole new unit, charger and two batteries free of charge. Their customer service is fantastic. On the other hand, returning anything to Amazon any more is a real pain. I cannot thank this seller enough, fantastic.

This Review is for the PowerExtra 2 pack Replacement for Sony NP-FW50 and USB Smart Display Charger.I purchased this for use with a Sony RX10 Mk III. Though I've not had these for long they work well and have equivalent capacity to the OEM Sony battery (see below).There is a Caveat though that I've seen on both of the brands of NP-FW50 (the other I've tried is a Wasabi brand BTR-FW50-JWP) and that is that the Battery Meter on the RX-10 doesn't function accurately / reflect the charge state of these batteries. What I have found is that when using the Sony Battery once the meter turns orange (replace battery) you have approx. 5 minutes of run time before the camera will shut down, but with both of the aftermarket batteries there is significant power remaining... In one case a few minutes after the low battery indication came on I just set the camera on my desk and started recording 1080p video to see how long it would continue to run and was able to record over 35 minutes of video before the camera powered down. So if this might cause an issue for you the way you use your camera you might want to pick up OEM replacement batteries.. but at Two for $25 including a USB Charger compared to $50 for an OEM I'm quite happy.A note on capacity.. I checked the charge milliamps from camera power down to full charge for both my OEM Sony battery (which was used as I purchased my RX10 and battery Used, but in great shape so I doubt it saw much use), the Wasabi and the PowerExtra batteries using the usb charger included in this package and a usb power monitor and here's what I came up with for full charge numbers:Sony - 1973 maWasabi - 1845 maPowerextra - 1832 maNote: I'm not saying my cheap usb power monitor is accurate and that these are accurate numbers, but the take-away is that since I used the same charger and measuring equipment the numbers do show that both the Wasabi and PowerExtra batteries do have approx. the same capacity as the OEM battery that I have.So 4 of 5 stars only because of not accurately indicating remaining power on my RX10 M3.I haven't tested the charger for charge times etc. compared to a Sony charger or just charging the batteries in the camera but it seems to function well enough. As for the "Smart LCD" display it's basically the typical 4 bar battery Icon that flashes with the charge state being shown by solid / non flashing segments for each of the two slots. Also- you need your own 110V to USB adapter to use this.. It does not include one.Also I've seen some negative comments on this charger being slow and not working etc. that I want to address. I think what some people are running into is that they don't understand electrical current ratings... On the back of this charger it states "Input: USB 5V 2A (Min)" and "Output: 8.4V 800mA". Most cheap 110V USB adapters don't put out that much current (1.5A seems to be the most common), So if you plug this thing into an under-rated adapter or port you won't get the output current and might even damage you equipment if you try charging both batteries on something that is not rated for this load.Now don't hold me to this but is appears that the 800mA output is likely for each battery channel which would make sense (0.8A + 0.8A = 1.6A @ 8.4v with a minimum input of 2A at 5V), so probably in a pinch you could use a 1.5A usb port / power hub with satisfactory results if you just charge one battery at a time.

Works as it should charges fast and love it has both usb c pro and usb a built in.

I’ve been using these rechargeable camera batteries for several weeks now, and they’ve exceeded my expectations. The battery life is impressive—easily lasting through long shoots without needing a quick recharge. They hold their charge well even when not in use, which is a huge plus if you’re shooting intermittently.Charging is fast and reliable, and the batteries don’t overheat or cause any issues with my camera’s performance. I also appreciate that they’re environmentally friendly and cost-effective—no more constantly buying disposable batteries.Overall, these are a must-have for any serious photographer. Highly recommended for both amateur and professional use!

I haven't played with it much,buti am liking it so far. Being able to change two batteries at the same time is great.

Fair price and it does what it should, multiple batteries
