There are two items to note. One, it is a manual generator with no battery. So if you're not pedaling you won't be able to charge anything. Two, it is very light weight (nice) but because of that it is also very unstable. The manual suggests screwing/clamping it down to something. This is a good idea if possible, otherwise you need to sit with your legs directly over it so it doesn't slide away, which can make pedaling a little awkward. However both of these are noted by the products manufacturer and I pretty much knew/expected it so I didn't feel the need to knock of a star in the ratings since they weren't a surprise.
willingness to work with me, a very demanding customer. I went with four stars because there is
room for improvement. The product performs as advertised and generated enough power to keep your
cell phones and tablets charged. The design is innovative, and the portability excellent. My goal was to use it as an exercise bike
and the stress of the weight and force pedalling exerts caused the Powerbox to break. This is not the fault of the Powerbox per se, it does
the job. The housing is plastic and not intended to be stepped on, or abused like a bicycle. Let's face it bikes are made of steel.
The product is terrific for Apple Products and chargers. My Samsung Galaxy Note 3 and Samsung Note 10.1 with two amp chargers
taxed the Powebox to the limit, mainly because Samsung has maxed out fast charging and as long as I used the Powerbox as a hand
pedal unit it was reliable. Using the Powerbox in that fashion provides a great upper body workout. I have two Powerboxes and I am satisfied. My only complaint that may not be possible to correct is the unit is noisy and sounds like an electric drill. In a hurricane or blackout, who cares, right. If you use this every day for charging your phones in the house or an apartment expect some negative feedback from those not pedalling. It is annoying. Ken has indicated he is working on a more robust higher power design, and I expect that will be
another breakthrough in Generator design. If you ar an enthusiastic Prepper or just an interested engineering type who cares about power generation and emergency services, I wouldn't wait, I'd buy a Powerbox. If you have a problem K-Tor has the best customer service I have ever dealt with.
We also demonstrated it to our self reliance group, where it got a lot of feedback and interest. With that many folks looking at it, it got a lot of handing around and cranking, but held up fine with no issues. The "why do the pedals have reflectors" question got some laughter. From other reviews we have seen, it gets asked a lot. And yes, we know the answer...
It took a bit of getting used to its unique output. We are experienced with low voltage (12 volt) direct current power production, and with high voltage (120 volt) alternating current production, but 120 volts of direct current is uncommon. The saving grace is that any 120 volt switching power supplies don't care if the power is AC or DC. But anything with a transformer, like typical 'wallwart' supplies will not work. And it is hard to tell by looking if a supply is switching or not. The type of power supply known as a 'brick' that has an input and an output cord (as opposed to one that plugs directly into the wall like a wallwart) is usually a switching supply. And a supply that states it will use anything between 120 volts and 240 volts AC is typically a switching supply. USB chargers worked just fine, and we powered our laptops with no issues.
The Power Block is rated at 20 watts. If you want to charge a 12 volt DC battery, you will need to use a charger that uses the aforementioned switching power supply. K-Tor sells such a charger for $18. The problem is that this charger only outputs 0.8 amps at 13.8 volts, which equates to 11 watts. It would be nice if the battery charger could utilize the full 20 watts of the Power Box.
If future enhancements are ever considered, a direct USB charging port would be great, as would a direct 12 volt battery charger port, negating the need for the charger.
Overall a very nice product to keep you from sitting in the dark with no communications in a grid-down situation.
Does what it is supposed to do that is generate power.
Would have liked it evenmore than now, if it had come with a bracket/stand to which we can secure it. Pedalling it while sitting on chair as showed in demo is not possible right out-of-box.. Pedals could come with some straps to secure the foot on the pedal... etc.
