PackTenna <http://packtenna.com/> has a end fed half wave
antenna with a 50:1 transformer called the PackTenna Mini:
"This compact wire antenna is ideal for SOTA activations,
camping, backpacking, and travel. The PackTenna Mini End-Fed
Half Wave Antenna combines a 50:1 UNUN, winder and antenna wire
in a compact unit that is quick to set up and take down. The
antenna comes with 40' of 26 AWG copper clad steel wire with a
great "silky" jacket to minimize wire tangle. You can cut the
wire to any band from 20 meters and up in frequency. You can add
additional wire for lower frequency bands as well. This is a
single band antenna and does *not* require a tuner."

As others pointed out, to get any real benefit from the EFHW it
needs to be a real half wave or very close to it, necessitating
a transformer to shift the impedance into range of the ATU or a
purpose-built matching network (tuner). Shifting the length
from a half wave simply turns the wire into a "random wire".
