PORTKEYS BD1 Reviews
Good but one mayor flaw
By Rafael
Rated 4 out of 5

The design and build quality of this product are excellent. Being able to adjust the position easily is a huge plus, and the cable feels very reliable. On the negative side, the USB-C port is only for input, not output. Having a USB-C power out is incredibly convenient on other brands I own, so missing that feature here is a bit disappointing for accessory-heavy setups. Still a very well-made piece of kit overall.
good but flawed design for portkeys LH7H 7

purchased this for the portkeys LH7H 7, the battery dummy works really well. has multiple ways to power the monitor. I purchased it for the usbc slot which is where my review drops . the usbc slot is too close the the monitor body and in order to use it properly i had to grind down a plastic lip to fully access it.
