Performances:
Plugged directly into a wall outlet, the flow is excellent, even between two remote rooms 15m. (A diode indicates by its color quality Green debit> Orange> Red)
I also tried plugging in extension cords. There, the flow takes a hit, and depend on several factors (quality strip, the number of attached devices, etc). Avoid even if our facilities at home almost all revolve around a power strip or UPS. Prefer a single wall outlet.
