Powerbank 5V 2A With Screen Black

Powerbank Circuit With Lcd Screen 5V 1A Dual Usb Output

Micro Usb Input Lithium Lion 18650 Battery Charging Mobile Portable Power Supply Battery Phone

     Powerbank circuit with dual usb output and lcd screen indicator. Battery capacity, output voltage and currents are shown on the Lcd.  It can be turned on and off with the button on the side. The product turns on with a long press of the button and turns off with another long press. The status of the product can be observed with the led indicator. The 3.7V battery voltage is boosted and transferred from 2 usb outputs as a 5V source for external use. It charges the battery connected to the board over the micro usb input socket.

     A 3.7V lion battery connection is made over the B+ and B- pads. More than one battery can be connected in parallel. An increase in the number of parallel batteries increases the charging time. The discharge time also increases. The battery capacity should not be greater than 20000ma. Reverse battery connection damages the product. If batteries connected in series are connected, the product is damaged.

Warnings:

• Reverse connection of the battery causes permanent damage to the product.
• Battery connection cables should not be made with thin wires. They should be able to carry 5A current. They should not be too long
• A quality battery should be used. Do not use old and worn batteries.
• More than 1 3.7V batteries cannot be connected to this circuit in series. You can increase the number of batteries in parallel. An increase in the number of parallel batteries increases the discharge time, of course the charging time also increases.
• You should not use batteries with protection circuits. Current limited batteries may prevent this board from operating at full capacity.
• Type c is only an input port. it does not output
• Do not solder the batteries with soldering irons for a long time and at high temperature. Use of nickel wire is recommended.
