Apple’s new 12W power brick enables faster charging of your iPads, iPods and iPhones. Apple stopped short of divulging specifics when asked to quantify the “fast, efficient charging” claim on its online store. “We don’t have an exact percentage of how much faster it would charge but you should see an increase in speed”, the company told 9to5Mac.

Enter Mike Flaminio of Insanely Great Mac, who took it upon himself to figure out non-scientifically the exact difference. An interesting video he posted claims the new power brick is able to charge an iPad between 30 and 45 minutes faster compared to the old (now phased out) 10W adapter. Yes, two extra watts of power make a difference. Check out his clip right below…

Insanely Great Mac (via 9to5Mac) wrote in YouTube description:

The new 12 Watt USB Power Adapter delivers a few more watts for your iPad. The goal is to reduce charging times slightly over the 10 Watt version.

Charging an iPad draws full twelve watts of power, but only five watts of power is required to charge iPhones and iPods with Apple’s new and juicer power adapter.

Here’s the clip.

The Apple 12W USB Power Adapter is a $19 value from the online Apple Store. It works with all your iPads, iPhones and iPods, just like the previous 10W model.

So what do you think?

The 45-minute difference in iPad charging time doesn’t seem much on paper, but is a factor knowing Retina iPads take several hours to charge to 100 percent, no?
