Battery life claims, and flying with a massage gun
Updated
Battery claims on our shortlist run from up to 2 hours to up to 6 hours, and three listings give no hours at all. At 15 minutes a session, a 6 hour claim is about 24 sessions and a 2 hour claim is about 8. Most claims are at the lowest speed, so expect fewer.
- TOLOCO EM266 hours
- RENPHO Thermacool 23 hours
- Hypervolt 2 Pro3 hours
- Theragun Prime (6th Gen)2 hours
Sessions per charge
| Gun | Claim | 15 minute sessions | 10 minute sessions |
|---|---|---|---|
| TOLOCO EM26 | Up to 6 hours, depending on speed | About 24 | About 36 |
| RENPHO Thermacool 2 | Over 3 hours | About 12 | About 18 |
| Hypervolt 2 Pro | Up to 3 hours | About 12 | About 18 |
| Theragun Prime | Up to 2 hours | About 8 | About 12 |
Plain arithmetic: claimed hours times 60, divided by the session length, rounded down. The C2, D6 Pro and RENPHO also have a 10 minute auto shut-off, so a single session stops there unless you restart it.
mAh is not hours
The C2 lists 2,000 mAh and the D6 Pro and RENPHO list 2,500 mAh. That is battery size. Runtime also depends on the motor, the speed and how hard you press. The C2 and D6 Pro listings do not turn battery size into hours. The RENPHO does, in a Q and A: over 3 hours. Compare mAh only between guns from the same maker. Cleveland Clinic notes that some guns run for hours while others need a charge within about 90 minutes, and that swappable batteries cost more up front. The Hypervolt 2 Pro is the one gun here with a detachable battery.
Charging
- The C2 charges over USB-C, with A to C or C to C cables. The maker says 1.5 to 2 hours with a 15 W charger.
- The Q2 Mini charges over USB-C from 5 V 2 A adapters.
- The TOLOCO comes with a USB cable but no wall plug.
- The Hypervolt 2 Pro uses its own charger. The listing says to charge for up to four hours before first use.
Flying with a massage gun
Hyperice says the Hypervolt 2 Pro is TSA approved for carry-on. For the battery itself, TSA says spare lithium ion batteries that are not installed in a device must go in carry-on bags only, and that rechargeable lithium ion batteries are limited to 100 watt hours each. So if you pack a spare Hypervolt battery, keep it in your carry-on. None of our listings give a watt-hour figure, so check the label on the battery, and check your airline's rules too.
For a carry-on gun, the checker's travel setting points to the Q2 Mini at 0.95 lb. See our shortlist.
Health note. This is general information, not medical advice. Keep the gun on muscle, not bone, and off the head, face, the front of the neck and any injury, bruise or open wound. Ask your doctor first if you are pregnant, have or have had a blood clot, have a pacemaker or other implanted heart device, have a bleeding disorder or take blood thinners.
