I'm reaching out to inquire about a specific fan model that I've come across, which I believe could potentially meet our needs. I'm particularly interested in the battery-operated version of this fan. Could you provide me with detailed specifications, including dimensions, performance metrics, and any available color options? Additionally, I'd like to know about lead times for production and any minimum order quantities that might apply. Furthermore, if there are any variations of this model or similar products that you offer, please send that information along as well. Pricing details, warranty information, and any bulk purchase discounts would also be appreciated. Looking forward to your prompt response as we're aiming to make a decision soon. Thank you!
