USB cables are not fast or slow at charging, they merely carry the current from the charger to the device. The chargers are what make the difference. For most Kindles and Fires a 9W or 10W charger (2 Amps) is going to give you the fastest charge. The 5W chargers (1 Amp) will still charge but more slowly.

Not likely, at least if it is the kind of charger made for USB devices. There are fail safes built into the electronics to close the circuits in case of an overload. That likely won't stop a direct lightning strike from frying the device, but most anything else should be stopped before it causes damage, at least if you use a standard USB charger. Each device is designed to allow up to a specific current, and anything beyond that should get blocked. Having said that, I would not tempt fate and use a charger with more than 10-15W (2 to 3 Amps) on a Kindle.
