A DIY power bank with a complete DC-DC converter to boost the Li-ion voltage to 5V USB voltage. For this powerbank kit you only need a Micro USB cable and a 18650 Li-ion battery. The converter module has a built-in Li-ion charge and protection circuit against over and under voltage, over temperature (chip) and short circuit protection.
This power bank is a plug-and-play module and has no buttons. There are LEDs that indicate the status for discharging, charging and fully charged.
Note: This DIY Power Bank is only suitable for use with standard 18650 batteries without protection circuit with the dimensions 18mm x 65mm. In our webshop, the 18650 batteries from Panasonic and Samsung are suitable and the 18650 batteries from Keeppower are not suitable.
* At a lower current, the DC-DC converter will turn off after about 8 seconds and go into standby.
