I'm interested in sourcing a slim aluminum power bank with a capacity of 10000mAh. Specifically, I'm looking for an order of 500 units. It would be great if you could provide details on the available color options, any customization possibilities, and your pricing structure. Additionally, I would like to know about the lead time for production and shipping, as well as the quality assurance measures you have in place. If you have any product specifications or technical data sheets, please share them as well. I'm eager to evaluate your offerings and consider potential partnership opportunities. Feel free to include information about bulk order discounts or any additional services that you provide. Looking forward to your prompt response!
