乌干达采购需求：充电宝

I'm looking for some detailed info on the pricing for a 20,000mAh power bank. Specifically, could you provide me with your best price per unit and any bulk order discounts you might have? Additionally, it would be great to know about the available colors and any other features or specifications that come with this model. If you could also share your lead times for delivery and any warranty or after-sales support options, that would be super helpful. I'm interested in placing an order soon, so any info you can provide will be much appreciated. Looking forward to your response!
