Didn't order because of shipping rates. It was almost $10 for one. WTF? I know these were FSSS, but I don't really want to spend $20 to save what should be $2 or $3.

I don't know where I'd be without Prime. Probably a lot wealthier. And to the post above re: a 2A adapter, what is the max amperage that these devices can handle? Because I imagine at some point you run the risk of overheating or otherwise frying something at too high of a current. Edit: Looks like an official 1.8A adapter is available for $20, so I suppose they can handle at least that much. http://www.amazon.com/Amazon-Powe...y_e_text_y I think this is still a slick deal nonetheless, especially since the cable is not permanently attached to the power adapter.

Note: You can damage a device by using a charger with a lower maximum current rating than the device being charged will draw, like using a 10A device with a 2A charger. Generally, it's not dangerous to do this with cell phone chargers, but I'd worry with a laptop or larger resistor based appliance. Last edited by Mixels; 11-24-2012 at 09:32 PM.. |

Ah ok, so it's more like the device is pulling the power rather than the adapter pushing it to the device. And the rating is the max it can provide. Got it. Ty! So now I wonder, how would we know how much the device can actually pull? How would we determine the cut off point where the adapter is overkill? I guess someone could hook a Kill-A-Watt or multimeter up to the device while it's charging on an adapter that's probably too high rated for it, and see exactly how much current it pulls. Or is this info buried somewhere in the tech specs... Last edited by dorkino; 11-15-2012 at 12:57 PM.. |

Basically, as long as your using a charger that provides voltage and current for which the device is rated, it should work. Higher current will charge a battery faster if the device will draw it, but there's no way to tell without trying it how much current a device can handle. It depends on a lot of factors, including the charger being used, the cable, the circuitry of the device being charged, and other electrical draws inside that device.
