Nano ONE V Mount Battery 3400mAh(50Wh/14.8V) with D-TAP,USB-C,USB-A,Micro-USB Ports,Portable Rechargeable V Lock Battery for Cameras/Camcorders/MacBook/LED Lights/Monitors

This lightweight battery will give me enough juice to run my camera all day. I also use it to charge up internal camera batteries. Works great to fully power my Blackmagic Cinema Pro camera as well.

This was my battery of choice for my Sony A7iii Camera rig set up for videography! This is used to power up my Atmos Ninja 5 and it makes it last a long time!! I highly recommend it

The display would show that it's outputting power when its not plugged into anything. It also would not charge. When plugged into USB C via a PD 30 charger, the battery would not charge and also get very hot. I'll be going with a more reliable brand.

I like the size, weight and function that this unit provides. I use external v-mount batteries to power my Canon R6 video rig. The battery extends the operating life of my camera and external monitor/recorder. Depending on the nature of the product I'll alternate between 50 and 100w/hr versions of this particular battery. Works as intended and meets specs.

I am really glad to have purchased this battery. Its size is perfect and the screen is very informative.

Got this V Mount external battery for my camera setup and also to use with HDMI transmitter. This has greatly expanded battery life. The display is very informative and easy to read. Small and lightweight so it does not add much to your pack when carrying it around. Easy to use and has multiple 5-12v outputs usb-c, std usb, and d-tap. This could also be used as an emergency charge for your cell phone or laptop. Charging time seems pretty quick. Very durable and heavy duty casing.

This is a pretty small battery which is great for some smaller gadgets and easy to bring around. The battery life isn't the best since it is small, but that's to be expected. It feels like a pretty good quality and I like how I can see how much life is left on the battery and I think is good value for the money

Don't buy this from Amazon. Of the two I bought, one stopped charging after a year of use. I emailed FXLion who told me I'd have to deal with Amazon for a solution. Amazon says the product is only returnable within 30 days. Good to know I wasted $250 bucks. It's not like I'm trying to screw anyone over. Just replace your defective product. Will not buy again or recommend and will encourage other pros to steer clear of this brand.

Very lightweight and does the job but little expensive otherwise it's good

I've been using this primarily for charging devices for my kids during long trips. The display screen is great for keeping track of capacity and it was quickly able to charge both our Samsung, OnePlus, and Google phones.

I wanted to try this Nano One battery because of the d-tap port and v-mount adapter. I normally use devices that required being powered by v-mount or d-tap and its small size makes it very portable. The top of the battery has USB, micro USB and USB C ports to charge the battery, but you can’t use those ports to charge other devices such as your phone where as other v-mount batteries I’ve used had the ability to charge devices with at least USB A. I wish all of the ports were backwards compatible. I tested the d-tap on a video light at 100% output and was able to get about 15-20mins before it got drained. Recharging the battery on a v-mount charger took under 2 hours to fully charge. I then tested the battery on a portable field monitor through the v-mount connector and it ran solid for 1h 45mins. The field monitor is also older and has internal fans, so I was surprised it even lasted that long. Some newer monitors could probably get many more hours from it. Considering how tiny this battery is, it certainly provides enough power for some of your standard devices. I would have liked the top ports to output power as well. I like the lcd display that shows charging status or available power. The rubber covers make it weather resistant and the side grips make it easy to handle. The plastic housing is durable and can probably take a few drops. It’s a good alternative to buying a larger battery especially for smaller devices that may not consume a lot of power.
