Macbook and 85W Charger

I wonder if the MBP charger can work with macbook normally.
I lost my charget and search for the charger on ebay. it loooks like the mbp charger is more efficient and same price so if it work, I will go for it. have any body tried?

 

. Macbook PRO charger output: DC18.5V 4.6A
. Macbook charger output: DC16.5V 3.65A

I would strongly recommend AGAINST mixing it!

cheers ...

 

I believe it works. I've done it before, and i've asked an apple employee and they said its ok.

 

I believe that you are correct based on the fact that there is different voltage output between the two.

This discussion has been talked about before and it seems to be fine. You just can't use the macbook charger on the macbook pro.

 

I thought you could use the macbooks on the pro, but it just wont charge as fast?

 

For charging alone? probably, if the comp is not up and running. Voltage and amperage are important factors to run the whole circuitry of the board and not just the battery alone.

Starving the system with less power input leaves open to hardware problems.

One of the reasons why the magsafe connector is the same across the whole mac lineup, is so that they can be used interchangably. I know for a fact that the MBP charger can charge a macbook (although not sure about the other way around)

When they introduced the air, you could use any of the other magsafe chargers with it, and use its charger on any other mac.

Again, apple made the new cinema display with a magsafe connector. They don't specify which laptop its good for, and im pretty sure its good for them all.

I think that macs are designed so that they can accept the different voltages that the chargers put out. Otherwise I don't think apple would have made the connection the same throughout the whole lineup. They'd just be asking for trouble if people mixed them up.

 

^^ Point taken. But I personally would not put my mac through this test

Furthermore the MacSafe adapter is an innovation to the power connecting, doing away with the plugin like other non-mac system, to make it simple for the user. It does not translate to interchangeable power bricks.

Quoting from Apple in a wiki read:
"Though the 60 W MacBook and 85 W MacBook Pro MagSafe connectors are identical, Apple recommends using only the adapter provided with the machine. The MacBook Air has a smaller 45 W version of the MagSafe adapter."

Would love so see/read that someone has a hand-on experience with interchanging the adapter though.

i've charged my macbook pro using a macbook charger.

 

It shouldn't be a problem either way. Using a MB charger on a MBP may mean that the charging time is longer and if you are using the MBP, the charging might stop since all the power is going to the machine. Using a MBP charger on a MB should have less problem since the MB will only draw what it needs rather than the charger forcing power into the MB.

Still it's better to use the proper charger with the model in question. It might not cause problems otherwise, but I doubt Apple would support it if something goes wrong.

 

Using a MBA charger on a MBP probably would not work, or will just charge very very slowly. But MBP charger > MB charger >MBA charger.

 

guessing thats a typo.

 

Simple deduction based on numbers; I would like to read real personal test numbers on this.

Is this a fact? Can you back this up? I have seen and experienced enough dead batteries and comps at power spikes in adapters, to believe that the comps are "smart" enough just to "draw what it needs"

Sensible statement.

cheers ...

 

I'd think the difference would be that apple knows that their laptops have the possibility of using different voltages from the charger. So they could make sure that it doesnt draw more then it needs. Other computers though, usually only have the one charger, and the one voltage, any spike would not be expected, and would do damage.

That being said, if you were using a MBP charger on a MB, and there was a spike in voltage, i dunno what that would do.

 

We all hope that Apple takes in consideration about the machine's ability of not "drawing"more power.

But we are also looking at a difference of 2V in both chargers and also in wattage. This is a big difference in term of electricity. Jamming down2 extra volts and wattage into the circuit, unless Apple says it officially, I would not take the chance to have the tiny circuitry in my macbook board to take this hit. Smart oor not, it wont be able to realise the higher charge "that" quick.
