1. Charging indication: the charging display will show IN letters 2. Output load indication: long press the LED button after connecting the load, the output will start, the display will show OUT letters and the relative output voltage and current 5V1A or 5V2.1A 3. Protection function: the protection circuit of the boosted lithium battery has been integrated to prevent over-discharge, overcharge and overload 4. Note: B+ and B- connected to the boosted battery must not be reversed, reverse must burn, can be connected to a lithium-ion battery can also be connected in parallel with a number of lithium-ion battery 5. Capacity of not more than 200,000 mAh, voltage 3-4.2V can be used, lithium positive pole connected to B +, lithium negative pole connected to B- 6. Size: about 5.8 x 2.7 x 1.5 cm
1. 充电指示:充电显示屏会出IN字母 2. 输出负载指示:接通负载以后长按LED灯按钮,输出启动,显示屏会出现OUT字母和相对输出的电压和电流5V1A或5V2.1A 3. 保护功能:已经集成了被升压锂电的保护电路,防止过放、过充、过载 4. 注意:接被升压电池的B+和B-一定不要接反,接反必烧,可接一节锂电也可以并联多节锂电 5. 容量不超过20万毫安,电压为3-4.2V都可以使用,锂电正极接B+,锂电负极接B- 6. 尺寸:约5.8 x 2.7 x 1.5 cm
