Hi Tina:
My names is Alex and I work for the company Bike2Power. We specialize in pedal-powered USB chargers, and have numerous solutions for different levels of cyclists with different level of touring experience.
The kit you were taking about is sufficient to charge up your iPhone 4 - it looks like our SpinPOWER I4 (since the price is the same, they may be buying from us, and shipping to you). Be aware that the dynamo that generates the power creates some drag (1-2 mph) on the wheel, which may or may not be sufficient for your purposes. Also, this charger will not be sufficient to charge a tablet - it produces power of 500 mAh. More information here: http://www.bike2power.com/SpinPOWER-Chargers
I agree with Shane - hub USB is the best option with the most stable power. But you still need a USB converter to convert the AC power from the dynamo into usable DC power to charge your devices. We have a highly popular solution, called a LightCharge USB Charger, which is compatible with most standard hub dynamos, such as Shimano and Schmidt. It has a USB port for your USB-chargeable devices, and a separate leg for a bike light. More information here: http://www.bike2power.com/LightCharge-Chargers
Please note that again, hubs and USB converters are not sufficient to charge the tablet.
We do have a solution that in combination with either SpinPOWER or LightCharge, is able to charge a tablet PC. I used it myself to charge my iPad mini, and my colleague uses his to charge his iPad. It is the BikeCharge Power Pack, a bike-mounted power pack that can be charged from a wall outlet, or from the bicycle USB charger. More information here: http://www.bike2power.com/Accessories/BikeCharge-Weatherproof-Rechargeable-Bicycle-Power-Pack.html
I hope the above is useful to you. Feel free to contact us with any questions - we are normally very good at responding.
Best regards,
Alex
