Any device with a switching charger of less than 20 watts will work with the Power Box. This includes all modern cell phones, smart phones and all Apple products.

 

Universal Pedal Powered
Electricity Generator

The Power Box is a pedal generator that can be used with your legs or arms. It generates electricity as you pedal, like on a stationary bicycle. Charge the batteries of a full range of portable electronics. Or, charge external batteries to power laptops and all kinds of appliances — either directly from the batteries or through an inverter. The Power Box has a universal outlet. It allows you to plug in chargers from anywhere in the world to charge your portable electronics. The Power Box is a great addition to emergency and survival kits.


Powerful and Versatile

The Power Box can produce up to 20 watts. It can directly charge a full range of portable devices. Because it is so powerful, it can charge more than one device at a time — like a smart phone and a tablet. Since it can be cranked for long periods of time comfortably, it can be used for higher power applications that it cannot charge directly. Simply charge an external battery and run your appliances, either directly from the external battery or through an inverter.

Small, Lightweight and Portable

The Power Box folds, in seconds, to the size of a shoe box — 12 x 5.5 x 3.5 inches. It weighs just 4 pounds, 11 ounces making it very lightweight and portable. It is smaller and lighter than an exercise bike. It provides similar cardio benefits. And it generates electricity.

Highly Efficient Design

The Power Box is designed to be very efficient. It converts the generator output to 120 Volts DC with 85% efficiency. 120 Volts DC is compatible with all switching chargers — the type used with all portable electronics, because they are also very efficient.

The Power Box for Emergency Power & Preppers

The Power Box is great for emergency power and should be on your checklist for basic emergency survival kit supplies. For disaster preparedness, it belongs in every bug out bag and 72 hour disaster kit. Survivalists and Disaster/Doomsday/Armageddon Preppers view our pedal generator as a great addition to their survival kits. Add the Power Box to your list of survival supplies. Feel confident that you can charge devices and generate power in emergency situations — from an earthquake to the apocalypse.

  • Cell phones
  • Mobile radios (like hand-held ham and emergency radios)
  • Tablets
  • LED lanterns
  • GPS devices
  • MP3 and DVD players (to entertain when the lights go out)

And, you can use these devices while they are being charged.

Charge multiple devices at once — up to the maximum power of the Power Box — with a simple extension cord. 

The Power Box is also a great back up to solar power in case of prolonged periods of cloudy or stormy weather.

The Power Box for Medical Devices
If you have medical devices that need to be kept running no matter what, The Power Box can help. No matter what the circumstances, it will keep your medical devices working.

It can be powered by other devices like water, wind or any other power source, as long as it is not overloaded and doesn’t exceed 1.5 cycles per second.

The Power Box for Camping and Hiking

The Power Box is foldable, compact, and lightweight. And it has a small footprint. It is portable and can be carried anywhere. The size of a shoe box and less than 5 pounds, it can power all of your essential emergency electronics and the Kindle or tablet you’re using to keep a log of your trip.

Many of our customers use K-Tor devices for physical rehabilitation. The hand crank charger, the Pocket Socket, and pedal generator, the Power Box, provide a simple form of exercise for arms or legs. The resistance is adjustable based on the load put on the generator.

The Power Box for Exercise

The Power Box converts mechanical effort into electricity. So, it can be used as an arm or leg pedal exerciser that has a practical use as well. Think of it as a small stationary exercise bike with a dual purpose. It’s portable, compact, and folds to the size of a shoe box. You can use it at home, under the desk at the office, and while traveling. And, you can adjust the load to vary the resistance and fine tune your workout.

We tested the Power Box at various loads with a healthy male, age 59, with a resting heart rate of 60. These were the results:

Good budget-friendly option
Color: Black, Size: Pack of 1, Color: Black, Size: Pack of 1
The chair arrived 4 days early and was easy to put together by following the instructions carefully. It feels sturdy and comfortable. It does support the lumbar region of the back and the arm rests are adjustable vertically as well as the head rest. I wish the arm rests were able to rotate in and out for added customization and that the back of the chair could be adjusted up and down for more precise support. But for a budget chair, it does a good job.

A solid chair for the budget conscious sitter.
Color: Black, Size: Pack of 1
While this is not THE most comfortable chair, let's face it - if you sit for long periods, what chair IS? I bought this chair because I'm making a career change. I've returned to school and spend hours at my desk. At the age of 50, sitting for a long time with my nose pointed toward a book can be hard on the seat, back and neck. I looked at all kinds of office chairs and settled on this one, primarily because it was on sale, was in my budget and so I clicked the "Add to cart" button and hoped for the best. It was delivered, and I had to work that evening, and when I got home my 17-year-old son had assembled it. My theory on the simplicity of assembly can be deduced from that sentence above. He didn't have any extra parts left over and the chair was complete! I sat down. I leaned back. I shifted the lever that keeps the chair in an upright position and sat straight up. Okay! I can live with this. It has been almost two full months of using this chair and I have no problems. Pros: easy to assemble sufficient comfort level - adequate cushion in the seat can be leaned back or pop the lever in to stay straight up rollers on bottom headrest is adjustable affordable easy to clean arm-rests can be moved up or down height adjustment is self-explanatory - you'll figure it out the "lumbar" support is actually comfortable - it's "there" if you back up to it but if you scoot forward just a bit, you won't feel it if you don't want to sit like that Overall this seems like a chair that's going to last me for a few years, at least, and not fall apart. In the context of size, I'm not a small or extra larger person. I'm an average middle-aged woman with meat on the bones. The seat is plenty big enough. I would recommend this chair as an upgrade to the hand-me-down office chair that just isn't comfortable any longer.

Love this chair!
Color: Black, Size: Pack of 1
I had an office chair that cost $300 more than this chair - had it for years, then things started breaking down on it. I read about this chair and, wow! I wish I had known about it sooner. It's more comfortable and it's not a chore to sit for a couple of hours working on designs. Wonderful design - supports my back well and it's very stable, easy to adjust.

Good chair with some quality issues
Color: Black, Size: Pack of 1
I've been using this chair for 12+ hours a day for the last 5 or 6 months and so far it is much better than my last chair I bought at Staples with a few problems. First, overall the chair is still comfortable when set properly, the cushion on the bottom is a little worn out but is still comfortable and I find the backrest comfortable except for the lumbar support which has very little cushioning and feels like a plastic brick being pushed into my back, however I find that I can keep it mostly out of the way most of the time and it isn't noticeable when I carry most of my weight on my upper back area while reclining. The reclining angle is super comfortable and the mesh on the back is not noticeably worn out. I like the headrest which is made of a cushioned mesh, its not better than a pillow but it's very comfortable to be able to rest your head in a chair you are going to sit in for long hours and gives good support. The arm rests don't feel amazing, they have a very stiff plasticky cushion feeling that I'm not much a fan of in terms of pure comfort but they get the job done as I mostly only rest my elbows on them when typing. The arm rest adjustment has a pretty good height range and I keep them at the highest settings and set as close to the chair as possible. While the chair may be comfortable, I have had some quality issues that bring down my opinion of the chair. First, my right arm rest does not go as high as my left arm rest and I have to set the left one down two positions to match the right one Second, the back rest locking for the upright position is broken but I can rarely get it to work as long as I don't put much weight on the back. I would imagine that most people would want to lock the chair upright as opposed to the other positions. Third, the 3 screws holding in the backrest untighten themselves over time, causing the backrest to move to its furthest back position and rock left or right if I lean on either side. When I tighten them again they will usually last about 1-2 weeks before becoming mostly loose again. There is no danger of the screws completely falling out though, just losing their tightness Lastly, I'm not sure how stable or secure the wood panel at the bottom of the seat that everything attaches to is strong enough, I used to have my armrests adjusted out further from the center but when I would lift up on my arms to adjust my seating position I would occasionally hear a sound of the wood stressing under the torque from the armrests. since I moved both armrests as close to the center as I can this has not happened; I would like them a little bit wider but I don't want to risk breaking the chair over it. Also, one of the factory-installed screws in the bottom seat panel fell out and wont stay back in but I haven't noticed any problems other than the risk of stepping on a screw caused by it While this is likely the most comfortable chair I've ever sat in, I have to give it 3 stars for the uncomfortable lumbar support and the quality control issues. If the QC issues were fixed I could easily give this chair a 4 star review
