That's pretty impressive. It's well made, robust and very compact for the power it can deliver and the way it can deliver it. It looks neat but this cleanliness comes at a price as the screen is tiny and very difficult to read, especially at first glance. The information displayed is also the bare essentials and a few "nice to haves" are definitely missing. This is ideal for projects that take a while and gives you the peace of mind to focus on your work without having to constantly check the battery status. It's advertised for use with a camcorder camera but has many more uses including phones, tablets, cameras, flashlights, lamps, laptops... and makes an excellent addition. The battery has a V mount and is easy to attach. It has a variety of ports including USB-A, USB-C, D-TAP, 8V DC and 12V DC, all of which have dust covers. The lettering on the ports is tiny and difficult to see, especially in low light. It has an intelligent BMS chip, which means it can charge multiple devices with different needs at the same time, and that's pretty convenient. It also supports high-performance USB-C bi-directional power delivery up to 65W. It will be worth it for some people who need this standard equipment on a daily basis, but for a general amateur this is more of a nice touch than a need, and I am would spend my money elsewhere.
