話題沸騰中の How Long Does It Take to Charge a Lithium Ion Batteryについて、多角的な視点を分かりやすく掲載しています。

So, how long does it take to charge a lithium-ion battery? It depends, but usually 1-2 hours for phones, 2-3 for laptops, and 4-8 for cars. The biggest lesson? Don’t stress about the last 20%. That’s the battery’s slow, careful breathing. And don’t buy the cheapest charger on Amazon—you’ll end up waiting twice as long and possibly frying your device. In the grand scheme of life, waiting an hour for a full battery is nothing compared to how long we wait for the microwave to finish. Patience, young padawan. Your lithium-ion battery is doing its best, and honestly, that’s more than we can say for most of our other gadgets.
