• Right pedal
• Left pedal
• Main body
• Feet (2)
• Instruction manual
Now that we setup the Power Box, and of course you use it with your hands, but it's really designed to be used with your feet, and it's very easy with your feet and you can pedal for long periods time with your feet. It is very important that it's on a stable surface and doesn't move around. We currently have it setup to charge two things at the same time: a tablet and a cellphone. This is done by using a simple extension cord. Start pedaling, come up to speed quickly and establish a normal rhythm at one and a half cycles per second.
For those of you that are gonna be pedaling for long periods of time, we find it much easier to be sitting in an easy chair, reclined, when you're pedaling. The unit is in fact designed to be screwed down to a piece of wood. There are four holes in each of the four corners of the feet underneath the pins, and it all screws down to a piece of wood, so you can screw it down to a floor, or you can screw it down to a piece of wood that's held in an angle, like this.
To operate devices that are beyond the Power Box's 20-watt capability directly, how you would do this is you would charge a battery first, and then you can use that battery to operate the other device. So for example, this is an external battery on a laptop. You would charge this from the Power Box and then you will connect this to your laptop. I also have connected to the Power Box right now, a standard sealed 12-volt lead acid battery. This is the one that's used with the Power Wheels kids toys. You can charge that up with the Power Box and then you can run all kinds of devices off of that 12-volt battery.
One of the great things about the Power Box is because you can pedal for long periods of time, it's very versatile. You can use it to charge external batteries and of course, there's a wide range of sizes of 12-volt batteries, and you can run many things directly off 12-volt. But you can also run an inverter off of a 12-volt battery and you can run pretty much anything that you can't run directly. So for example, we have a full-sized laptop here plugged into this inverter and I also have an electric fan.

Neat Backup charger

I have been interested in this for a while so i decided to bite the bullet and buy it. Its very simple to use but i recommend bolting it down like they say in the instructions, otherwise it moves/ tilst up. Much easier to pedal than use the smaller hand crank version.
Pros:Doesn't require the sun to charge devices
Cons:Would like more resistance in the pedal.

Using feet is so much better than arms
October 21, 2013
The idea is a vast improvement over trying to crank 90 RPM with a hand held version. My arms would get so tired it was nearly impossible to keep going. The pedal version is definitely better because of the obviously stronger leg power. The one thing that I would say that would make this work so much better is the addition of a gear, so that you don't have to physically spin your pedals 90 rpm -- a gear that allows you to spin anything less, such as 45 or 60 rpm, while the gear transfers the speed to the charger so it turns 90 rpm would be a lot easier.
The reality is - spinning 90 rpm with your feet on the pedals takes a lot of energy and concentration, it's practically the equivalent of sprinting, and you can't do it "mindlessly", as soon as you think about anything else and try to let your body go on auto pilot, your legs slow down to just a little less than 90 rpm, and I presume that it just doesn't charge much or at all at that pace (I noticed my charging light wavering when I slowed a bit).
It's just hard to keep up a non-stop sprint pace for 10-15 minutes or more, and the actual resistance isn't that hard (way better than with your arms), it's just the speed is tough to keep up.
I assume that an extra gear to translate the speed would add a bit of size, weight, and cost, but I would pay it. It would make the whole thing much more effective.
Pros:easier to spin with legs and arms
Cons:hard to keep up 90 rpm for as long as it takes to charge a device or battery
Best Uses:blackouts and power outages, possibly camping
the amount of charge you can accumulate realistically would not be much more than your phone, flashlight, maybe a radio etc. but you'd end up being very judicious about using those devices because of the difficulty in keeping up the 90 rpm for the 10-20 minutes or more to charge those devices.
