Power converter from Li-Ion battery

You can use this 65W converter with the PD function to power or fast charge your devices (laptop, mobile phone, portable speaker, etc.). I also use it to power my soldering iron everywhere. I use a 6S Li-Ion FPV battery as a power source. You can use a battery with other voltage (up to 8S), but for correct indication the battery charge level, you need to solder the corresponding jumper on the indicator board.
