A USB-C charging cable built to the highest power rating the USB standard allows — 240W, which is 48 volts at 5 amps. Enough for a gaming laptop, and far more than a phone will ever draw.
It is the ceiling of USB Power Delivery 3.1, the specification that introduced Extended Power Range, or EPR. Before it, USB-C topped out at 100W. EPR raised that to 240W using higher voltages — 28V, 36V and 48V — rather than more current. An EPR cable is simply one built and certified to carry those voltages, which is why the standard requires it to be visibly marked as such.
Nothing charges faster than it needs to. A phone that asks for 25W draws 25W down this cable and no more. The 240W rating is a ceiling, not a speed — what it buys you is that the cable is never the bottleneck, whatever you plug in next.
⚠️ And the cable is only one of three things that have to agree. The charger has to offer the power, the device has to ask for it, and the cable has to carry it. A 240w usb c cable plugged into a 65W charger delivers 65W, and that is the charger’s limit, not a fault.
Any USB-C cable carrying more than 60W must contain an e-marker chip. It is not optional — the specification forbids high current on an unmarked cable.
The chip is a label, not a safety device. When you plug in, it tells the charger and the device what the cable can carry: its maximum current, its voltage rating, its data speed. The charger reads that and decides how much to send. An e marker cable that reports 5A gets offered 5A; an unmarked one is held to 60W by design.
⚠️ This is worth being precise about, because listings often are not. The chip declares capability. It does not provide overcurrent, overvoltage or short-circuit protection — that circuitry lives in the charger and in the device being charged, not in a cable. Anyone selling you protection in a lead is describing something that is not there.
What the chip does buy you is honesty in the handshake, and that is most of what separates a cable like this from a cheap one.
These two specifications are independent, and this is the single most misunderstood thing about USB-C.
A cable can be rated for the full 240W and still carry data at USB 2.0 speed — 480Mbps. That is completely normal, and most EPR charging cables on the market are exactly that, because the power rating and the data rating are negotiated separately.
⚠️ We do not have the data rate confirmed for this cable, so we are not going to claim one. If you need a lead for fast external drives or a display, tell us and we will point you at one where the figure is documented. If you need to charge a laptop, the data rate is irrelevant and this is the right cable.
A gaming or workstation laptop whose supplied brick is 180W or more. This is the category EPR exists for.
One cable for everything, so the same lead handles the laptop, the phone and the tablet without anyone wondering which is which.
Future-proofing a desk. 240W is the top of the standard — there is nothing above it to upgrade to, so a cable bought now will not be outgrown.
Stocked in Melbourne, not drop-shipped with a three-week wait. Order before 10am and it ships the same day via Australia Post with tracking and insurance, backed by our 90-day warranty.
And by a team who will tell you when you do not need the expensive one. If your laptop charges at 65W, a 240w usb c cable is not going to make it faster — we would rather sell you the right cable than the dearest one.
Tell us what you are charging, then order today.
Works with any device that charges over USB-C, at whatever power that device and its charger agree on — from a 5W earbud case to a 240W workstation laptop.
Where the full 240W is actually used:
Where it works but the ceiling is never reached:
⚠️ Three things have to agree, and the cable is only one of them. The charger must offer the power, the device must request it, and the cable must be rated to carry it. Plugged into a 65W charger this cable delivers 65W — that is the charger’s ceiling, not a fault in the lead.
⚠️ Both ends are USB-C. This is not a lead for a USB-A port, a Lightning device or a barrel-plug laptop — we stock those separately, so tell us what you are charging and we will match it.
