Will this charge my HP laptop at full speed?

If your laptop uses a 65W HP adapter with the same connector, yes. It outputs up to 18.5V and 65W, matching the original.

Is the cable detachable?

No. The 70.9-inch cable is fixed to the adapter, so you cannot swap it for a USB-C or longer cord.

Only if you buy the USB-C version. The barrel-tip version fits specific HP models, so check your laptop's port before ordering.

It is the lowest of the seven stores listing it new as of November 7, 2026, so it is a strong price for a genuine HP 65W adapter.

Yes. Many buyers keep one at home and one in a bag; it is small enough to carry.
