Percussions per minute, amplitude, and a stall force rarely given
A massage gun is a motor driving a head back and forth, and three published figures describe what it does mechanically. Percussions per minute is the speed, quoted as a range across the speed settings, and it is the number every listing gives. Amplitude — the stroke length in millimetres — is the one that actually distinguishes devices, and many listings omit it: a 12 mm stroke and a 5 mm stroke at the same speed are different tools entirely. Stall force, in kilograms or newtons, is the pressure at which the head stops moving, and it is the figure that tells you whether the device does anything once it is pressed into a muscle. Few makers publish it; those that do are worth noting for that reason alone. Beyond the mechanism, the practical figures decide whether it is used: battery capacity in mAh with a stated runtime, weight in grams, which matters because it is held at arm’s length behind a shoulder, and noise in decibels, which the better makers now publish. The heads supplied — ball, flat, bullet, fork — change the contact area, and a device with six heads is not better than one with four, it simply arrives with more plastic. Some models add a heated head or a force display; both are described rather than specified. This site reports the figures the maker publishes; what percussion does to a muscle is a medical question and is not one of them. We compare amplitude, stall force, speed settings, percussions per minute, battery capacity, mass and noise level.
24 W brushless, 1800 mAh, 460 g, 45 dB
A mini gun that publishes its motor in watts rather than in a vague claim — 24 W brushless — with a 1800 mAh battery and a published 460 g mass.
Best for: Somebody comparing on battery life and weight rather than on stroke
Stall force 60 lbs, 6 mm depth, 1000–3200 rpm, 0.47 kg
The only gun on this shelf to publish a stall force — 60 lbs — and the only one with a pressure-adaptive mode that raises speed automatically as it is pressed.
Best for: Anybody who wants to know what happens when the device is actually pressed into something
46 dB at the first setting, 5 levels, 5 heads
The only listing here to state the setting at which its noise figure was taken — 46 dB at the first level — from a maker specialising in health devices.
Best for: Somebody who wants a figure they can actually interpret
7 mm amplitude, thermal head 40–45 °C / 10–15 °C, 430 g
The only gun here with a heated and cooled head, publishing both temperature ranges — 40–45 °C and 10–15 °C — at 430 g and under 40 dB.
Best for: Somebody who wants heat and cold from the same device
12 mm amplitude, 3200 rpm, 20 speeds, 9 heads
The deepest published amplitude in this family at 12 mm, with twenty speed settings up to 3200 rpm and nine heads in a carry case.
Best for: Somebody who wants the deepest stroke available on this shelf
10–12 mm amplitude, 3200 rpm, 1500 mAh, cooling
A mini gun with a published 10–12 mm amplitude and an integrated cooling system for continuous use, charging in a stated 1.5 hours.
Best for: Long sessions, where a device that heats up is the limiting factor
10 mm amplitude, 32 speeds 1400–3000 rpm, folding
A folding gun with an extending handle and five locking angles, thirty-two speeds across a published 1400 to 3000 rpm, and a 10 mm amplitude.
Best for: Reaching the middle of the back without a second person
7 speeds 2200–3300 rpm, 10 heads, 2600 mAh
The largest battery in this family at 2600 mAh, with a published speed range of 2200 to 3300 rpm across seven settings and ten heads.
Best for: Somebody who wants the longest battery and will accept a high minimum speed
10 mm amplitude, 3200 rpm, 0.68 kg, 10-min auto-off
A 10 mm amplitude at up to 3200 rpm with a published 0.68 kg mass and a ten-minute automatic cut-off protecting the motor.
Best for: Somebody who wants a deep stroke and charges everything from one cable
Only the specifications at least four models out of five state. A column that is more empty than full compares nothing.
