What input voltages does the 85W Magsafe 2 power adapter accept? I have an 85W Magsafe 2 (A1242, MD506LL) power adapter which has been happily driving my MacBook Pro from US and Canadian 110V AC power. I am about to take this power adapter to Europe. Will I be able to plug this adapter into a plug adapter (from North American type B socket to Europlug type C plug), which passes through mains voltage and frequency unchanged, and plug that into normal outlets in Italy, Austria, Croatia, and the UK (type G plug for the UK of course) and have it operate correctly?

What input voltages and frequencies does the 85W Magsafe 2 power adapter accept?

I have been unable to find definitive specs on the adapter itself or on Apple's website. I would hope the answer is "110-240V 50/60Hz", as it is for my cheap USB power bricks, but I'm not going to plug in my expensive MacBook Pro based on hope. I'd appreciate pointers to definitive information.
"Input: 100-240V~ 1.5A 50-60 Hz Output:20V [DC] 4.25A max"

The answer is in fact on the side of the adapter. There is text on the plug end and on one of the narrow sides of the adapter. The input information is on the narrow side, in low-contrast light-grey fine print on a white background (thank you, Apple). With a light and a magnifier, my old eyes were finally able to make it out.

"[DC]" refers to a symbol with a solid line next to a dashed line, meaning "direct current".
