Iriver h320 / power draw

[Oakbough]

I hope this is the right discussion platform for this question. If not, please direct me to the appropriate place.

I need to know if there is a difference in the power draw of the iriver h320 using rockbox, as opposed to the standard iriver software.

I am setting up remote systems where I need to know how much this unit will draw under recording situations.

I appreciate any input.

Thanks

Do you mean to ask how long the battery will last, or how much it will draw from a power adapter?

[Oakbough]

I would like to know how many watts of power the unit uses. If anyone knows amps and volts as well, that would be wonderful.

Basically I have the init plugged into a larger battery bank.

Does that help?

I don't think anyone will be able to accurately answer your question.

Partially the issue is that how much power will be drawn is dependent upon exactly what the device is doing at the time, as well as battery condition and other issues.

It honestly will be in your best interest to make measurements on the exact device you plan to use in the state you intend to use it (such as recording in whatever codec you're going to use, etc).

Right on, I thought I would throw the question out there and hope someone might know.

Thanks for the help.

Hi,

given that the unit can be charged from USB, I'd guess that you are safe with 5 V and 500 mA. I believe the stock charger is rated 5V/900mA, so that should really suffice.

I guess that the iRiver always draws the power from the battery, so that acts as a buffer if the device should need peaks of power (writing to disk for example).....

I need to know if there is a difference in the power draw of the iriver h320 using rockbox, as opposed to the standard iriver software.

In general Rockbox is a bit more efficient than the original firmware, users have reported longer times, although this applies to playback, not recording. It's impossible to compare the two for recording as the original firmware will abort after certain time (depends on bitrate) where rockbox does seamless filesplitting till your disk is full

I am setting up remote systems where I need to know how much this unit will draw under recording situations.

The only numbers I have is that when my unit was about one year old, I did a recording test with RockBox and it managed to record 12 hours with original battery. As noted above, maybe provide external power to be safe?
