Wireless Charging Power Banks

5,000 mAh, 5,200 mAh and 10,000 mAh, and one model listed at 6,000/8,000 mAh. A capacity change inside an existing shell is a cell and board change; a new size of pack needs new tooling.

Ask for the UN38.3 transport test report and the battery cell datasheet before you book. It is a separate document from FCC, CE and RoHS, which Sunning Tension holds for these markets, and it is the one that stops a lithium shipment at the airport if it is missing.

Many state short-circuit and over-charge protection explicitly in the spec table. Where a product does not state it, treat that as not recorded rather than not fitted, and ask for the board specification in writing before you place the order.

Yes, as OEM: your logo, artwork or slogan is printed on a model that is already tooled. Artwork setup is free. There is no tooling cost, and the minimum order is the model's own: printing a logo does not raise it. A printed sample with your artwork comes first. Your own box, insert and barcode cost USD 320 setup from 500 pieces, waived on large quantities.
