Buying Guide
What to consider when choosing a 4-channel TENS unit:
- Number of independent channels: More channels allow more zones to be treated simultaneously. Ensure the unit can support the number of pads you plan to place.
- Modes and customization: Look for devices with a mix of preset programs and customizable USER modes to tailor frequency and pulse width to your needs.
- Battery life and charging: Rechargeable models with long-lasting batteries reduce interruptions during therapy sessions.
- Pad count and layout: A higher pad count enables broader coverage. Check pad sizes and whether the device supports 8 pads or more.
- Safety and warnings: Avoid use if you have a pacemaker, are pregnant, or have certain medical conditions. Always follow manufacturer guidelines.
- Portability and design: If you travel often, a compact, lightweight unit with a carrying case is advantageous.
- Budget vs. features: Balance essential features (channels, modes, battery life) with price. More affordable models still offer effective relief when used correctly.
