We are a prominent medical device manufacturer in India, currently in search of a suitable Power Bank Station for a device designed for rural usage. We require a unit with a capacity of 333Wh, utilizing lithium-ion technology. Essential features include 400W AC continuous power output, pure sine wave AC output at 220V, and dual USB outputs offering 5V/2.4A. The device should support both solar charging (max input power of 60W) and a car cigar lighter DC output of 9-12V. It's crucial that the charging time does not exceed 10 hours with a 3A charger. Since the Indian market is quite price-sensitive, we ask for your most competitive pricing for an order of 1,550 units. Additionally, please provide details regarding the estimated delivery timeline. We have attached some photos for your reference to give you a better understanding of our needs. Thank you for your attention to this inquiry, and we look forward to your swift response.
