also old and power-hungry products work easily, even without connecting the power supply. with external 2.5 "hard disks make the most hubs without external power supply limp, the T7Hub seems to work very efficiently. the safe side I have connected nezteil and can connect so spontaneously external hard drives, without using an additional power supply being forced to.
with six connected devices in continuous operation, of which a printer behind 2.5m Extension Cable, I can after months of trouble-free operation, the device only recommend.
the hub is barely warm, the workmanship is impeccable.
geschmackssache is perhaps the arrangement of the USB ports, the distribution over the housing LIKE perseonlich good and saves space, but there are certain situations in which a single connection direction is beneficial.
5 points and a little enthusiasm for the brand DR. Bott!
