a $10 converter<\/a> that allows you to connect a MagSafe adapter to a MagSafe 2 equipped MacBook. There\u2019s only one small thing you\u2019ll want to be mindful of.<\/p>\nWhile the wattage for both adapters is the same 45W, the voltage is different. The new MagSafe 2 adapters output at 20 volts, while the original MagSafe adapters only output at ~18 volts. So if you use that converter to hook an older MagSafe adapter to your MagSafe 2 MacBook, charging can potentially take longer, due to the lower voltage output compared to the newer adapters.<\/p>\n
We don’t foresee any catastrophic problems from this, just the minor inconvenience of longer charge times when using the older adapter with the converter. How much<\/em> of a difference there will be, we can’t say at the moment; we\u2019ll have more info once the adapters are available and we can test it.<\/p>\nUPDATE: <\/strong>Testing has shown that because of the lower voltages in the 45 W and 85 W MagSafe adapters, charging your MagSafe 2 machine may take a little longer when using an original MagSafe supply with adapter. However, individual differences may not be as pronounced as originally estimated. The 60 Watt models are unchanged, so there shouldn’t be any difference in charging times between MagSafe and MagSafe 2 adapters.<\/p>\n\u2022 MagSafe 2 85 W = 20V@4.25A
