Posted in: Super rapid mobile USB battery charger See in context

@bence8810: Except that it doesn't. Even on Apple's own A/C charger (which doesn't have the 500 mA limit of most PC USB ports) the iPhone 4 only draws enough current to fully charge in about 2 hours. Regardless of the type and capacity, Li-ion batteries almost always take at least an hour to fully charge. Charging them more rapidly would drastically shorten the number of times a Li-ion battery can be recharged before it needs replacing.

@ka_chan: The Spanish flu of 1918-1920 didn't kill 25% of the world population, more like 1-3% according to different estimates (20-50 million out of 1.8 billion). The rate you quote is only the estimated infection rate, but most infected survived. "In Japan, 23 million persons were affected, and 390,000 died."
