After knee surgery or a hard training block, a cold therapy machine keeps cold water moving over the sore spot while you rest on the couch. We read the listings for the best cold therapy machines under 150 and scored five of them on stated tank size, cold time, pad fit and warranty.
This roundup scores five cold therapy machines listed under $150 on Amazon on what each listing states. Listings were collected 22 October 2026; prices change.
This article is informational and is not medical advice. Cold therapy strains the heart and can injure skin if a pad sits on bare skin too long. Speak to a doctor first if you have a heart condition, circulation problems, or are pregnant. See our Medical Disclaimer.

The best cold therapy machines under 150, compared on stated specs
Every machine here works the same way: a small pump moves ice water from an insulated tank through a wrap-style pad. What differs is the tank size, how long the cold is stated to last, how the pad fits, and whether the maker states a warranty. Timer controls range from simple session presets to programmable on-off cycling.
Tank, cold time and warranty
| Machine | Tank | Stated cold time | Pad | Warranty |
|---|---|---|---|---|
| Betooray Cold Therapy | 18 qt | Up to 18 hours | Knee pad, size not stated | 12-month |
| Aokeste Foot Therapy | 16 qt | 12+ hours | Foot, to US men’s 13 | 1 year |
| Onlycare Cold Machine | 11 qt | 12 hours | 10.6 x 11.4 in | 1-year replacement |
| Cameco Hip Ice Machine | 3.96 gal | Up to 12 hours | Hip, 2 straps | Not stated |
| Icythrp Cold Machine | 12 qt | 12 hours | Knee pad, neoprene | Not stated |
We read five cold therapy machine listings. Three state a warranty term, two include a water thermometer, and two include a pressure regulator or valve. None states a safety certification.
Who should not buy these
If a clinic will run a machine all day, these home listings state no duty cycle, so a commercial unit may fit better. If the sore spot moves from joint to joint, a single-shape pad such as the foot wrap or the hip pad will not follow it. And if your routine needs the longest stated cold time, only one listing here claims more than 12 hours.

Score notes
The Chill Score weighs performance 30, build 20, value 20, safety certifications 15 and warranty 15. Here, performance covers stated tank size, cold time and control features. No listing states a safety certification, so safety is zero across this roundup.
| Product | Chill Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Betooray Cold Therapy | 9.7 | 32 | 21 | 21 | n/a | 4 |
| Aokeste Foot Therapy | 9.7 | 30 | 21 | 20 | n/a | 3 |
| Onlycare Cold Machine | 9.6 | 29 | 20 | 21 | n/a | 3 |
| Cameco Hip Ice Machine | 9.6 | 29 | 20 | 20 | n/a | 0 |
| Icythrp Cold Machine | 9.5 | 28 | 19 | 20 | n/a | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score. Safety counts only for powered gear or where the listing states safety features; where it does not apply, the score is taken over the remaining 90 points.
Betooray leads on stated tank size and cold time, with a 12-month manufacturer warranty. Aokeste is the foot-first pick with a pressure valve and thermometer. Onlycare offers the most flow control, with 4 speeds and a remote.
Check Your Space First
- Footprints run from 10.6 by 10.6 inches to 15.35 by 11 inches: clear a flat spot beside the bed or couch before the first session.
- Listed weights run 3.53 to 4.67 pounds before water and ice are added.
- Plan your ice or frozen bottles ahead: listings call for up to 6 frozen bottles, up to 8 frozen bottles, or up to 10 standard 16.9-ounce bottles.
- Onlycare’s hose is 16.4 ft long, so route it where it stays out of the walking path.
- No listing states the plug type or voltage: check the listing if your outlet setup is unusual.
Common questions
How long does the cold last in one fill?
Stated cold times run 12 hours on three listings, 12+ hours on one, and up to 18 hours on one, depending on how much ice or how many frozen bottles you load. Makers describe rotating frozen bottles to extend a session. Check the listing’s figure against how long you plan to run it.
Do these machines need bagged ice?
Listings describe ice plus water, and several are built around frozen water bottles instead of loose ice: up to 6 bottles, up to 8 bottles, or up to 10 standard 16.9-ounce bottles depending on the model. Bottles mean fewer refills and less melt water to pour out.
How loud are they at night?
Four of the five listings state a pump figure of 15 dB or under, and makers describe them as suited to bedside use. Betooray is the one listing here that states no noise figure. Keep the unit on a stable surface so vibration does not add noise the listing does not promise.
Can one pad treat different body parts?
It depends on the pad. The knee pad listing also names shoulders, ankles, feet, hips and legs, while the foot wrap is foot-specific and the hip pad is hip-shaped. Match the pad shape to the sore spot rather than assuming one wrap fits all.
What does the timer do?
Timers set the session length. Common settings are 15, 30 or 45 minutes, or continuous run, with 3 or 4 flow levels on most models. Two listings add programmable on-off cycling, so the machine pauses and resumes on its own.
Do any of these state a warranty?
Three do. Betooray states a 12-month manufacturer warranty with 24/7 technical support, Aokeste states a 1 year warranty, and Onlycare promises a 1-year replacement with one-to-one help. The other two listings state no concrete warranty term.
