What reviewers say.

It helps me walk, hike and sit with ease. It worked better than expected—even for a friend who struggles to walk.

Electric Revolution

I'm thrilled it has no negative impact on my replaced hip or back. I feel years younger!

Nancy

These are not like the hip exoskeletons, I think these are more just to assist bad knees, and help you on the on the decline from a hike.

Reviews

Sarah Mitchell 

"I love spending time outdoors, but long walks and uneven trails can be tough on my knees. PowrKnee gives me that extra bit of support, especially when heading downhill. Really happy I gave it a try!"

David Thompson

"Going up and down stairs has always been a struggle for me. I've been using PowrKnee for a couple of weeks, and I can definitely feel the difference. It's not doing the work for me, but it makes each step feel easier."

Mark Peterson

"Took me a little while to get the straps adjusted right, but now it's really comfortable. The support is noticeable, and I like being able to adjust the settings through the app. Cool product!"

Alex Morgan

“It fits me well and feels lightweight. The adjustable straps make it easy to get a comfortable fit.”

Brian Cooper

"Wasn't sure what to expect at first, but I'm pretty impressed. The assistance feels natural once you get used to it. I mostly use it for my daily walks and it really helps on hills."

James Collins

"Easy to set up and works as expected. Took a few walks to get used to the assistance, but now I really enjoy using it. Definitely worth trying."

Chris Walker

"Fits well and stays in place while I'm walking. I was worried it would feel awkward, but it's actually easier to wear than I thought. So far, no complaints."

Ryan Anderson

"I wear these when I go for walks around my neighborhood. There's a pretty steep hill near my house, and I can really feel the assistance going up and down. Still getting used to the weight, but overall I'm very satisfied."

Thomas

"I used to hike almost every weekend, but over the past few years my knees haven't been keeping up. Decided to try PowrKnee and it's been a pleasant surprise. I can walk longer without feeling as worn out, and the downhill support is especially helpful. It's not the lightest thing to wear, but for me the extra assistance is worth it."

Frequently Asked Questions

What activities is PowrKnee suitable for?

PowrKnee is designed for everyday activities, including walking on flat ground, climbing stairs, and going up or down slopes.

It provides assistance when walking uphill or upstairs, and support and cushioning when going downhill or downstairs, helping reduce the strain on your knees and making everyday movement easier.

How does PowrKnee help reduce knee strain?

PowrKnee uses powered units positioned on both sides of the knees to provide assistance during movement.

When the system detects your walking movements, the motors deliver supportive torque at the right moment, working with your muscles to help reduce the effort required from the muscles around your knees.

Is PowrKnee suitable for older adults?

Yes, PowrKnee is suitable for older adults who can walk independently.

It provides assistance during everyday activities such as walking, climbing stairs, and going outdoors, helping make daily movement easier.

Please note that PowrKnee is a walking assistance device, not a replacement for independent mobility. It is not suitable for individuals who cannot walk on their own.

Can I use PowrKnee if I've had knee surgery or have an existing medical condition?

PowrKnee is designed to assist people who can walk independently. It is not a medical device.

If you've had knee replacement surgery or have conditions such as severe cartilage damage, a herniated disc, or a spinal cord injury, we recommend consulting your doctor or rehabilitation specialist before use.

Users with pacemakers should also seek medical advice before using the device.

How long does the PowrKnee battery last?

PowrKnee features a dual-battery design and provides over 10 hours of battery life under normal daily use.

Actual battery life may vary depending on the terrain, assistance level, and individual usage.

For longer walks or all-day outings, you can bring spare batteries and replace them when needed.

Does PowrKnee provide assistance when walking on flat ground?

Yes. In flat-ground walking mode, PowrKnee provides assistance based on your walking movements.

Whether you're taking a daily walk, walking for extended periods, or traveling, it can help reduce the effort required from the muscles around your knees, making walking feel easier and more comfortable.

Can I adjust the assistance level for each leg separately?

Yes. You can adjust the assistance level for each leg independently through the companion app.

For example, if your left knee needs more assistance, you can increase the support on that side while keeping a lower level on the right, allowing for a more personalized walking experience.

What should I do if I don't feel enough support when walking downstairs?

It may take some time to get used to PowrKnee's assistance and find a comfortable walking rhythm.

We recommend starting on flat, safe ground to become familiar with the device before trying stairs or slopes.

You can also adjust your walking pace and assistance settings to find what works best for you.

If you still don't feel enough support, please contact our customer support team for guidance before continuing to use the device on stairs.
