  • What does Autostart Mean/ Do these powerballs Require a Cord to Start?

    Both the Diablo Evo and Titan Pro are Autostart Powerballs. This means you do NOT need a cord to start them. They have built-in tensioners that are simply wound back and released to enable an easy start every time. Check out our videos page for starting techniques and tips.
  • What is the diameter and height of these Powerballs?

    The Titan is the largest Powerball ever built and is 80mm wide and 60mm in height. The Diablo Evo is substantially smaller at 65mm in width and 60mm in height. If you have very small hands, the Titan may feel awkward or large to handle, so we ask that you take this into consideration.
  • How much force / resistance / Torque do the Metal Series Powerballs generate?

    The Titan Pro generates 22.7kg/ 50lbs at 10,000rpm and the Diablo Evo generates 18.7kg/ 41lbs at 10,000rpm. 10,000rpm is an achievable spin speed for the average person. As your wrist, grip and forearm strength increases, your spin speed will become faster and you will be able to generate more resistance. While the metal series are calibrated to spin up to 20,000rpm, no human would have the grip strength to generate this type of speed. Theoretically, these products can generate over 40kgs / 100lbs but even the very strongest of athletes may only manage to generate max. 28kgs/ 60lbs. We look forward to someone going faster!
  • Titan Pro or Diablo Evo? Which model should I choose?

    This is a bit like choosing between your favourite children for us. Firstly, If you have very small hands the Titan may feel too large or be difficult to grip, so the Diablo may be a better suit. Alternatively, if you have very large hands the Titan is the model for you. The Metal Series Powerballs are the quietest models on the planet, but if you are looking to use yours in an office environment, we would recommend the Titan as it is a little bit quieter due to its internal sound dampener. Outside of that, both Powerballs feature the same precision-balanced solid zinc rotor inside, so their resistance output will be similar. The Titan is heavier so it will generate more resistance at the same speed, but the Diablo is faster, so it works out evenly!
  • How much do these models weigh?

    The Titan weighs 520g / 18.34oz and the Diablo weighs 357g / 12.6oz. Incredibly, with some training a person can hope to generate 60 times the actual weight of these Powerballs in resistance. A 357g Powerball can feel like a 20kg dumbbell in your hand, allowing you to build incredible grip strength as a result.
  • Are these models suitable for rehabilitation?

    Yes absolutely. These Powerballs generate anywhere between 0 and 60lbs depending on your grip strength. We simply advise people with injuries to use these high performance models at LOW SPIN SPEEDS for rehabilitation. Just like a sports car, these Powerballs are capable of high speeds, but it is important to stick to the 'speed limits' during your recovery. Spin nice and slow to begin with and build the speed and resistance as you recover and get stronger.
  • HOW DO THESE POWERBALLS REHABILITATE?

    Exercising with Powerball massively increases circulation and promotes the flow of oxygen-rich nutrients along the entire kinetic chain of the arm. These nutrients target and treat an injury at its source, actively repairing and rehabilitating damaged muscle tissue and relieving pain fast. Best of all, exercise with Powerball is 100% non-impact, so it will never worsen your injury or cause you further pain.
  • WHAT CONDITIONS DOES POWERBALL REHABILITATE?

    Powerball rehabilitates a wide range of finger, hand, wrist, arm and shoulder conditions. Many of our customers use Powerball to treat common injuries, such as RSI (tendonitis, carpal tunnel syndrome, tennis elbow, golfer’s elbow), broken bones, fractures & sprains, ligament & tendon tears, arthritis as well as general pain & inflammation.
  • WHAT PARTS OF THE BODY DOES POWERBALL STRENGTHEN?

    Powerball strengthens the entire kinetic chain of the arm - from fingertip right up to shoulder. If you’re interested in serious strengthening, then the Powerball Metal Series are the right choice for you. Strengthen your wrists for effective injury prevention, develop incredible finger grip strength and build muscle mass in the arms and shoulders - it’s as easy as picking up a Powerball.
  • HOW OFTEN SHOULD I USE POWERBALL?

    How often you use Powerball depends entirely on your level of fitness and whether or not you are suffering from an injury. For rehabilitative purposes, we recommend using Powerball for at least 3 minutes a day and at least 5 minutes a day for strengthening purposes.
  • WHAT IS THE FUNCTION OF THE LCD SPEED METER?

    Both the Titan Pro and Diablo Evo Powerballs feature a 6-mode LCD speed meter for keeping track of your strength and endurance gains. Monitoring your spin speeds will also help you to measure your rehabilitation progress and push yourself along during your recovery period. What’s more,the Powerball speed meter saves your highest spin speed so that you can constantly improve on your results and compete against friends for the top score.
  • ARE BATTERIES REQUIRED TO OPERATE THESE PRODUCTS?

    No batteries are required to operate these products. Powerball is powered solely by the rotation of your wrist.
  • DOES AUTOSTART POWERBALL COME WITH A LIFETIME WARRANTY?

    Yes. Every Powerball purchased through our website is covered by a gold-standard lifetime warranty.
