It does not include any power supply or tray. It did not include any documentation either, just a couple of boards.\u003c\/p\u003e\n\u003cp\u003eThe review is about a specific charger module, but any module with the TP4056 will have identical performance.\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0965\/3623\/2249\/files\/DSC_0562.jpg?v=1789235459\" alt=\"DSC_0562\" border=\"0\" loading=\"lazy\"\u003e\u003cimg class=\"alignnone\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0965\/3623\/2249\/files\/DSC_0563.jpg?v=1789235465\" alt=\"TP4056-1A LIPO Battery Charger Module\" width=\"241\" height=\"153\" border=\"0\" loading=\"lazy\"\u003eI got it in an envelope with 5 circuits on 2 boards and nothing else.
