The TENS 7000 has been the default recommendation from physical therapists for years. It is plain, a little dated, and gives you precise control. The AUVON is the modern challenger: rechargeable, full of presets, and built for people who just want to press a button and feel relief.

Pick the TENS 7000 If
- A physical therapist or doctor gave you specific settings to use
- You want to adjust pulse rate and width yourself instead of guessing what a preset does
- You like physical dials you can turn without looking at a screen
- You do not mind swapping a 9V battery now and then
The TENS 7000 does fewer things, but each one is under your control. Our full TENS 7000 review goes deeper on the modes.
Pick the AUVON If
- This is your first TENS unit and you want to try different feelings quickly
- You hate buying batteries
- You want extra pads in the box so you can treat two areas
- A built in timer from 10 to 60 minutes sounds useful
One catch: AUVON says the unit cannot run while it is charging, so plug it in before a session, not during. Not sure what to look for in general? Read how to choose a TENS unit.

The Bottom Line
Buy the TENS 7000 if you want control and a proven, simple tool, especially if a clinician gave you settings. Buy the AUVON if you are new to TENS, want presets to explore and would rather charge than buy batteries. Either one is a reasonable, low cost first step for everyday muscle soreness. Neither replaces a diagnosis for pain that does not go away.
