THE ESSENTIAL INFORMATION:
Do you allow custom orders?
Yes! We can create a custom order for your team, including adding on a logo or branding options. Please contact our team directly.
How does the device work?
As we exercise our body and muscle temperature increases. This increased temperature leads to a decrease in our ability to perform and also decreases our motivation to continue working.
Our devices use materials that specifically optimizes the glabrous skin found on the palms of your hands. This type of skin contains specialized blood vessels that rapidly exchange heat with the environment, making it ideal for efficient cooling. By targeting glabrous skin, palm cooling quickly reduces core body temperature, enhancing recovery and improving performance during intense activity.
What is so special about the palms of the hands?
The palms are covered by glabrous skin. Glabrous skin is hairless and has an amazing network of veins and arteries underneath called arteriovenous anastomosis (AVAs). This special network is incredible at helping regulate temperature.
How to use the AF Charge Bar (Patent Pending):
It is incredibly simple to use the AF Charge Bar. Prior to your workout, practice or competition be sure to cool your charge bar by sticking it in a refrigerator or refill it with cold water. The tool is designed with a certain type of metal and density that allows it to keep its temperature for up to an hour when filled with cool water. Ideally, the temperature of the AF Charge Bar is between 45-60 degrees Fahrenheit when being used.
To use the tool after it is cooled, simply hold the bar during rest periods. Rest periods could be between sets of strength training, while resting between intervals, during time outs or half time breaks or during breaks at practice. Anytime you've been exerting yourself and you want to keep your effort level higher for longer, hold your AF Charge Bar.

Care instructions
Sanitize/Cleaning. We recommend cleaining your device in between uses by different people. The device (metal cylinder) and its color should hold up to any cleaner of your choice. We also recommend hand cleaning the rubber end caps, inside and out, with warm water and soap weekly.
Do not squeeze the bar too hard.You do not want to limit blood flow through your palm, you simply want to cool and and have it circulate back through your body
Do not get the bar too cold.If you use the AF Charge Bar when it's too cold you could trigger your blood vessels to constrict. This is because you're sending a signal to your nervous system that you are too cold and it will want to take measures to heat you up.
If your AF Charge Bar is getting too warm, just take off the cap and fill it with water from a water fountain or sink. The cool water will bring your bar back to a cool temperature rapidly.

So far the endcap seemed to work quite well however, in the description online, it said they would fit a 2 inch aluminum pipe. This is not accurate. They are also too large for a 2.25 inch aluminum pipe. I was able to fit them on a 2.5 inch aluminum pipe, but it was a tight fit. My guess the optimal range would be more like 2.4 or 2.45 (however those sizes are not easily available) I am excited to try it out for my daughters when they play soccer in the hot month of September. I didn’t give a five stars because of the issues with the pipe size. Otherwise I’m satisfied.

Fits nice and tight so there's no leakage. Temperature is spot on with refrigerator thermometer.

Works perfectly.
Lucas A. 5/5 Verified
So much better being able to determine what temperature it’s at! No more guessing.
Chris M. 5/5 Verified
Works as advertised.
Ezeckel R. 5/5 Verified
Do exactly what they are supposed to do, but the only improvements I can see would be to highlight in green the “optimal cooling zone” for temperature, and highlight with other colors to to show suboptimal cooling zones. Colors may help for easy reference during a workout. Aside from that, excellent product that delivers.

Added value that I can track the temperature! Great device!
Reja B. 5/5 Verified
Awesome idea for the thermometer cap. But even with my reading glasses, I can’t make out the numbers. Wish there was a color coded inlay to show the optimal zone. After about 30-45 minutes of using it during a workout, need to pour in cold water or add ice cubes. Not a problem for me as I train at home, but it always leaks after I do this. The caps are properly seated and it isn’t overfilled. I rest it on a towel. Again no problem. Bottom line it works as advertised! Better performance at a very reasonable cost. Great job!

Thank you for the newly designed caps. They are more robust, have a wide base for support, and the recess helps protect the thermometer. All in all, excellent upgrade in design. Thank you again.

I recently upgraded my AF Charge Bar with the innovative TempExact Caps, and I couldn't be happier with the added functionality they bring to the device. These caps come with a built-in thermometer, allowing me to monitor the exact temperature of my cooling device while in use. Plus, for those who already own the previous version of the AF Charge Bar, these new caps are compatible and can be purchased separately. They fit seamlessly and roll smoothly, making it convenient to roll your feet or other body parts over the device. The temperature measurement is crucial for optimal cooling, and the ideal range of 45-60 degrees Fahrenheit is easy to maintain. With these TempExact Caps, I've enhanced my cooling experience and can confidently recommend them to anyone looking for precise temperature control with their AF Charge Bar.

The new thermometer is great for knowing if your unit is in the optimal zone for palm cooling. It is very quick in reacting to temperature changes as well! Great idea, a simple one but very effective. An awesome upgrade!
