In order to develop this oil diffuser ASAP,I want to freeze the product specification at first,see below items showed which i have already discussed with some factories:
the lasted working time: Normally,the lasted working time should be less than 2H,or else the the ultrasonic mechanism will be damaged;
I think this is fine. Most people do not spend an hour in the bathroom let alone two. I think we could make it automatically turn off after 15 minutes or something like that. So that we do not damage the ultrasonic. I think 15 minutes is a good amount of time for a shower. If it is not enough they can always just press the button again to re activate.

the capacity for the water tank:it will affect the amount working time;
The capacity will be determined but the size. I would make it as large as possible keeping it within the small dimensions that we have specified. Minus the room that the batteries and electronics will take up.

mist amount(output fog):the output fog of my sample is around 15ml/h,it will affect the amount working time too,we almost cann't see the fog from your sample,could you help to confirm which kind of sample is accepted?
I think the more fog the better. The 15ml /hour seems really small. You mentioned most samples you found have larger out puts? What is realistic based on the battery capacity?

The power:Due to the minimum working voltage is 5V and the working current is around 0.6A --0.8A,the best way is to use a Li-leo battery,the amount working time is only 1h--2h if we want to use 4 AA size batteries;
I think we better plan on including a rechargeable lithium battery. I think 1-2 hours of use is not acceptable. What will this do to the cost?
