马达加斯加采购需求：外接电池

I'm looking for a price quote for your ultra-thin magnetic wireless power bank with a capacity of 5000mAh and the ability to deliver both 20W and 15W charging. Please provide details on bulk pricing, any available discounts for larger orders, and lead times for delivery. Additionally, I would appreciate information about the materials used, color options, and any customization available. If there are product specifications or certifications, please include those as well. Looking forward to your prompt response!
