KRK Rokit 5 G4 from an iPad Pro: will the USB-C port feed the Volt 276?
The iPad Pro 11 (M5) port is rated 15 W and the Volt 276 draws 5.0 W at most — 10 W of margin. The ports that fall short are the 4.5 W phone ports, and they fail as dropouts, not as silence.
Yes, with room to spare: the iPad Pro 11 (M5) USB-C port is rated 15 W and the Volt 276 draws 5.0 W at maximum — 10 W of margin. Apple's Accessory Design Guidelines give the Pro 3.0 A and the iPad Air 11 (M3) 1.5 A; the Air's 7.5 W still clears the Volt, but with 2.5 W of headroom rather than 10, and that is the margin a hub, a drive or a charging cable on the same port eats first.
The monitors are not the difficult part. The Rokit 5 G4 has its own amplifiers and takes a balanced line signal on a combo XLR/TRS jack rated 5.12 kΩ. Nothing here goes to speaker terminals, ever — there would be a power amplifier at both ends of that cable, and joining them is a topology error, not a matter of sound quality.
Bus power actually runs out on phones. An iPhone 16, a Pixel 10 and a Galaxy S25 all supply 4.5 W — 0.5 W short of the Volt's 5.0 W maximum, yet comfortably above the 3.5 W it typically draws. That gap is precisely why the failure is not silence, which would at least be honest: the interface works until demand rises, then clicks and drops out, and people spend weeks blaming drivers and buffer sizes. USB-A hosts are further away still: a FiiO R7 is rated at the USB 2.0 floor of 500 mA / 2.5 W, a Raspberry Pi 5 allows 600 mA / 3 W.
If it drops out: run the Volt from its own supply and let the port carry data only, or use a powered hub. On the iPad Pro — or a MacBook Air 13 (M5), also 15 W — bus power is not your problem, and the fault is somewhere else.
