Colour Name:10 x TP4056 "Just Choose IZOKEE: Your expert for Micro-Electronics! One-Stop-Shopping with Various Electronic Modules and Components! " Specifications: Input interface: Micro USB Input Voltage: 4.5V-5.5V Full charging voltage: 4.2V Max output current: 1A (Adjustable) Charging Precision: 1.5% Operating Temperature: -10 ° C ~ +85 ° C Item Size: Approx. 25 x 19mm The output current and the corresponding resistance: RPROG(K) - IBAT(mA) 30K - 50mA 20K - 70mA 10K - 130mA 5K - 250mA 4K - 300mA 3K - 400mA 2K - 580mA 1.66K - 690mA 1.5K - 780mA 1.33K - 900mA 1.2K - 1000mA Notes: 1. The tested Ampere meter can only be connected in series with the 5V input of the charging board 2. Charging current is better to be 37% of the battery capacity. For example, if you want to charge a battery of 1000mAh, 400mAh current will be enough. 3. The connection wire should not be too thin or too long. 4. Please make sure that it is well connected to the battery. 5. Please do not connect the output reversely, otherwise it may burn the chip. 6. If the voltage is higher than 5V, it will cause the charging current less than 1000mA, which is normal. When the voltage is high, the chip will be heating and automatically reduce the charging current, not causing the burn of the chip. Package Includes: 10 x 1A 5V Micro USB TP4056 Charging Module
