Bộ 10 Bảng Mạch Sạc Pin Lithium 5v Mini Usb 1a Tp4056

10Pcs 5V micro 1A TP4056 Lithium Battery Charging Board Power Charger Mo Specifications: Charge module: Linear charging Current: 1A adjustable Charge precision: 1.5% Input voltage: 4.5V-5.5V Full charge voltage: 4.2V Led indicator: red is charging blue is full charged Input interface: mini USB Work temperature: -10℃ to +85℃ Inversed polarit: NO Size: approx.22*17*5mm/0.86*0.66*0.19'' Net weight: approx. 15g Quantity: 10pcs Note: Ampere meter can only be connected to 5v input end of the module. It is better that the charging current is 37% of the battery capacity. If you charge to the battery of 1000mAH, current of 400 is enough The connection wire should not be too thick. Make sure the connect point is good. If the input voltage is too high, like 5.2v, the current will be less than 1000mA, it is normal. It is protection function, auto-substract the charging current to avoid burn damage to chip NO Reveral polarit. There is no effect when Input reverse connect chip. But it will damage the chip when Output (battery side) reverse connection Please allow 1-3mm differs due to manual measurement. Due to the different display and different light, the picture may not reflect the actual color of the item. Thanks for your understanding. Included: 10 x Board Charger Module
