How Many Mah Do The Gp32 Consume ?

How many mAH do the GP32 consume ?
And the GP2X?
Do we exactly know it ?

I think you've misunderstood the concept of MAH...

I think you mean MA (or milliamps). A 2500MAH cell will power something at it's native voltage (1.2V) for 1 hour per 2500milliamps of current required.

So....

1 2500mah battery powering a 500MA device should (in theory) last around 5 Hours if that device uses 1.2v.

The gp32 can obviously survive on 2.4V from 2x 1.2V batteries. If it lasts 7 hours on these to 2500Mah batteries, then it is probably sucking somewhere in the region of 2500 / 7 Ma (or approx 350Milliamps). The GP2x lasts around 3 hours on the same batteries, so this equates to 833Ma of current required.(or thereabouts).

If you up the clockspeed (on either unit) they suck more Ma (but the same voltage), so the same batteries would last less time. For example, if upping the GP2x to max makes it suck 1250Ma, then the 2500Mah batteries would last 2 hours (2500 / 1250).


Any clearer?

 

[Jegriva]

For me it's enough, thank you.

 

[m8ex]

That was a good explanation but M=Mega ane m=milli.
I really want two of those 2500MegaAmperehours (=2500000000Ah).

Also, most places don't tell you the usage specification to get the most of the battery. Eg. Some 2500mAh batteries will only allow you to draw there 2500mAh load if you do it at between X and Y mAh. For example, a battery could last 8 hours at 300mA current draw, but only 2 - 3 hours at 500mAh.

The best batteries for high current draw (since the 2x seems to like to use something between 500 and 800mAh) is batteries aimed at digital cameras and the like.

 

[Axeman]

Yeah - my Ms and ms were a little interchangable there wern't they!

 

[Squidge]

ms? Millisecond? You mean mA ?

 

[deadlychicken22]

ms? Millisecond? You mean mA ?

​

I think he meant m's as in multiple m's (meaning that he did it more than once).

 

[Axeman]

yep - but it wasn't gramatically correct to put an apostrophe in when I was pluralizing something (and its something that bugs me ).

But what if the gp32 and the gp2x are set to the same clockspeed and ~volume level...

THEN which one is the most energy efficient?

​

At a guess, The GP32.

​

well, you're right, but it makes it difficult to understand so I usually decide to give up gramatical correctness for comprehension

​

yeah ur right..


the gp2x has an extra processor

Ooowww, Do i win a prize, Or maybe a blue peter badge.

Or damnation in hell.

Depends

​

No.... The GP2x has more efficient processors... The Gp32 won't run for anywhere near the same time at that speed...
