Can the Dynamo Generator be modified to link up with a USB car charger and be used to charge an iPhone (~5V, 3A)?

I don't know that it can (generator's voltage is only as stable as the speed of the bike?) Voltage is definitely generated and can be passed to other devices if properly wired. The key is the wiring.....

yes, but you have to make the adapter (if there is not one out there).. you take the AC output of the Dynamo, send it to a bridge rectifier, then a voltage regulator (to keep it at 5V)- then look up the right polarity and pins for a USB port or you blow out your phone.. then get the wires and plugs- sockets- put it together and finished.. the car charger idea will not work- it deals with the car's 12v DC- it might only regulate (drop the 12v DC to 5v DC) and not turn the AC to DC, the bridge rectifier will turn AC to DC..

I found this link on Instructables to make a high efficiency voltage regulator that will give you more power to charge and operate things. It's a little bit more complex, but there are schematics and step by step directions. You could probably make it with a trip to Radio Shack or an order from one of the online electronics suppliers (Digi Key, Newark, etc.)http://bit.ly/1CJj3CAI'll try to make one because I ride a ton at night and this time of year it's dark a lot.

The generator puts out approximately 16.7 amps, so it should work with that device.

Yes. The first one I bought from Amazon didn't work -- I guess it didn't supply enough amperage. But this one worked great with this cup:AC Wall to DC Car and Dual USB Charger Converter - Includes 2 USB Ports and 1 12V Cigarette Lighter Port Ideal for Charging GPS, Phones, and More While at Home

I LOVE the dynamo! The phone holder was a piece of crap. Stupid thing fell off even when my iPhone wasn't in it. So, I will use a different holder, but it was cool that it was charging. I am pretty sure it will at least extend battery life even if it doesn't fully charge the phone.

I think you might be able to use a car charger with it, as there's a DC input slot. I haven't tried that, though, so I'm not sure.

I am not an expert on this matter, but I think you can use a DC to AC converter (ie Cobra CPI 480) which can be used with either the cigarette lighter or direct to car battery cable attachments.

I had no luck using it to charge iPhones. If memory serves, it's output is inadequate.

I believe so. The USB charges an iPhone, so I don't see why it wouldn't charge it from the car charger (which has a step-down to ensure the 12Volt battery is not the charge you're getting). This little unit is SO useful that I'd still buy it - even if it didn't do that (but I'm pretty sure it will work for you for that use).

The specs on this device calls for 5V 1.5A power input. As long as the supply you have is also 5V, you can use anything capable of producing at LEAST 1.5A. Charging with a supply greater than 1.5A capacity will not hurt your device. I hope this answers your question. For an analogy, think about car batteries... More Cold Cranking Amps (CCA) will not hurt your car's starter motor. It's more capacity that may never get used.

No, this car charger is for phones with micro-usb connections, such as Android phones. The iPhones have Apple's Lightning connection.

The power supply is not included with the charger, and it can use anything that can supply the necessary current via a USB port. Therefore, yes, you can purchase any USB power adapter that plugs into the car's cigarette lighter receptacle. I can imagine that you would want one that can output 2A of current.And as other people have mentioned, the device is likely to slide off the surface of the charging pad, as your car accelerates or brakes, so a car is probably not a very appropriate place to use a wireless charging pad that does not have a way to hold the device in position.

I'm no expert, but I don't think so. First, this charger is excellent but it still takes a few hours to fully charge a laptop or iPad. So you'd be looking at a very long time for a car battery. Secondly, the charger adapters are designed for household electronics. I suppose someone more handy than myself might find a way to make it work and then if you had lots of time... I like the idea, though. Good luck!

No, cause iPhone has an exclusive connector, but you can use design cable of your iPhone connected to the USB port of this charger

With NO guarantee, I'd say "yes"...You would need a different cord and plug for the phone.The CIGARETTE LIGHTER plug from Samsung I purchased is ratedright on it as 5V-DC at 2000mAThat *translates* into being a "high power" or rapid USB charger device.There are three basic currents for USB. 500mA from a normal computer USB socket.Some computers or docking stations "can" put out 1000mA.I do not have your phone and can't say what it requires OR will tolerate.You might not want to hook it up and walk away from the car...(Or leave it hooked up too long. Like NOT overnight.)

Yes, definitely. What came with my iPad mini was 1 amp. This has approx 2A per device. I have a few PowerGen chargers at home and others in my cars.

I believe so. It has connections for a regular USB or the miniUSB. I use it with my LG Optimus with the miniUSB but I think even the IPhones can be charged by plugging into any regular USB power source. AND BTW... Great power source! I always have it in my purse and it charges my phone in no time!

Most certainly, YES but ONLY if you add a 5-volt AC adapter capable of supplying external power. See the comment under "Does this come with an AC power supply?" where someone suggested an Amazon part number. There's not really any way the seller can provide a power supply which is perfect for everyone, since people could use this as a small hub for memory sticks (very low power) or they could use it for charging 7 iPhones like you. You may be looking at 5v 10A AC adapter because most iPhones won't charge with less than 1A supply.
