Carry-on details
Allowed. TENS (transcutaneous electrical nerve stimulation) units can go in your carry-on or checked bag. At the checkpoint, it's easiest to take the unit out of your bag and place it alone in a bin — the wires and electrode pads can look unusual on an X-ray, and giving the officer a clear view speeds things up.
Checked-bag details
Allowed without restriction, though carrying it with you avoids the risk of a delayed or lost bag if you need it during your trip.
Special instructions
If your doctor has advised against X-raying your specific TENS unit, tell the TSA officer so they can screen it a different way.

FAQ
- Should I take my TENS unit out of my bag at security?
- It's a good idea. TENS units and their wires can look ambiguous on an X-ray, so placing the device alone in a bin can help you get through faster.
- Can I pack TENS unit batteries in checked luggage?
- Spare lithium batteries should stay in your carry-on. The device itself, with its battery installed, can go in either bag.
