Massage Gun Specs Comparison Chart
Every popular percussion massager's specs in one scannable table: amplitude, stall force, speeds, battery, and weight. Amplitude is the hero number, and here is how the field stacks up.
Amplitude (stroke depth) is the spec that separates real percussion from vibration: 16mm (Theragun Prime/Pro) is the deepest mainstream option, 14mm (Hypervolt 2 Pro) is a close second with a comfier grip, and 10 to 12mm covers value and budget guns. Stall force (how hard you can press before the motor gives) matters second, but several brands do not publish it. Speed count matters least.
Massage gun specs at a glance
| Model | Amplitude | Stall force | Speeds | Battery | Weight |
|---|---|---|---|---|---|
| Theragun Pro (5th Gen) | 16 mm | ~60 lb | 5 (app-adjustable) | ~150 min | ~2.9 lb |
| Theragun Prime (5th Gen) | 16 mm | ~30 lb (reported) | 5 | ~120 min | ~2.3 lb |
| Hypervolt 2 Pro | 14 mm | Not published | 5 | ~180 min | ~2.6 lb |
| Hypervolt 2 | 12 mm | Not published | 3 | ~180 min | ~1.8 lb |
| Ekrin B37 | 12 mm | ~56 lb | 5 | ~8 hr | ~2.2 lb |
| Renpho Active (budget) | ~10 mm | Not published | 5 | ~180 min | ~1.5 lb |
Amplitude and battery are manufacturer-published. Stall force is shown only where a brand states it; "reported" marks a widely cited figure the manufacturer does not formally publish. Weights are approximate and vary by attachment.
The two specs that actually matter
Ignore the speed count and the marketing horsepower claims. Two numbers decide whether a massage gun does real percussive therapy or just vibrates:
- Amplitude (mm): how far the head travels per stroke. 14 to 16mm is true deep percussion; 10 to 12mm is solid for most muscles; under 10mm is vibration with a marketing budget.
- Stall force (lb): how hard you can press before the motor stalls. Under 30 lb stalls on a quad under real pressure; 50+ lb handles dense tissue. The catch: many brands do not publish it, so treat unpublished figures with caution.
How to read the chart
Start with amplitude and match it to your tissue: endurance athletes flushing legs do fine at 12mm, while heavier lifters working dense muscle want 14 to 16mm. Then weigh stall force and weight against comfort: a lighter gun you will actually reach your own back with beats a heavier one that stays in the drawer. Battery only matters if you travel or treat multiple people.

Frequently asked questions
What is amplitude on a massage gun and why does it matter?
Amplitude is how far the massage head physically travels on each stroke, measured in millimeters. It is the single spec that separates true percussive therapy from vibration: 14 to 16mm reaches deep tissue, 10 to 12mm is solid for most users, and below 10mm is closer to a buzz. It is also the spec manufacturers publish most consistently, which makes it the fairest way to compare models.
What is stall force and is more always better?
Stall force is how hard you can press the head into a muscle before the motor stalls, measured in pounds. Higher stall force (40 to 60 lb) lets you apply real pressure to dense muscle without bogging down; lighter guns stall under heavy pressure. More is not always better for everyone, though, since high stall force usually means a heavier, louder device. Note that several brands do not officially publish stall force.
How many speeds does a massage gun need?
Most people use two or three speeds in practice: a low setting for sensitive areas and warm-up, and a high setting for dense muscle. Anything beyond five speeds is mostly a spec-sheet number. Amplitude and stall force matter far more than the speed count.
Which massage gun has the deepest percussion?
Among mainstream consumer models, 16mm amplitude is the deepest, found on the Theragun Prime and Pro. The Hypervolt 2 Pro sits at 14mm with a more comfortable grip, while value and budget guns typically run 10 to 12mm. For dense muscle and deep work, choose the highest amplitude you can afford.
