Bad things first:
1) The "8 volt" ports do not deliver 8 volts. I measured them in the 7.47 to 7.3 volt range. Maybe not a big issue, but I'd prefer them to be over by 0.1 volt (e.g. 8.1) as opposed to under by 0.53 to 0.70 volts.

2) The USB socket tries to be QC compatible and support the 9 volt output level, but in my testing, it failed, reaching only 8 volts (causing a QC device to reject it).

3) One of my (3) non-OEM NP-F batteries didn't positively lock into the battery plate. I feel that this is a problem with the battery, and not this product, as two other NP-F970 compatible batteries (with different brand names) did lock into it positively, but their push button/latch connects to a slot in the side of the battery and requires a relatively tight tolerance. I'd prefer if it had a big latch that held the back of the battery in place like many of my lights.

On the plus side, the 12 volt port provided a solid 12.1 volts, which is presumably what you would be using with the Black Magic Pocket Cinema Camera, for which it includes the BMPCC specific locking plug. It also includes a generic 5.5x2.5mm double ended barrel connector cable that can be used on the 12 volt or the "8 volt" ports.

The USB-A port works like a champ at 5 volts, providing a good 19 watts (5 volts at 3.7 amps).

Mounting options include a 1/4-20 stud, and a 1/4-20 socket. They include a cold shoe to 1/4-20 stud so that you can mount the battery adapter plate to a camera's cold shoe, or you can use the plate's 1/4-20 stud to screw it into a camera cage.

Indicator lights are minimal but functional (1 red led to show it has power, and 0-3 green LED's to indicate the remaining battery capacity.

The plastic of the plate itself is functional, but doesn't feel especially strong or "premium".

My overall impression is it will probably power a BMPCC, but there were enough downsides and disappointments that I wasn't really impressed with the product. If you don't need a full 8 volts from the 8V ports, or need QC capabilities from the USB-A slot, or have one of the non-standard non-OEM aftermarket batteries that doesn't quite meet the tolerances to lock into the plate, it should be just fine.
