HOW TO CHARGE POWER BANK ?

THE MOST IMPORTANT QUESTION IS THIS
i just use imax b6 ac charger to charge this power bank
BUT I FOUND THE CHEAPEST WAY TO CHARGE
YOU JUST NEED A 12 VOLT POWER ADAPTOR OF OLD WIFI ROUTER OR ANY OTHER
+ HOW TO CHARGE WITH ADAPTOR ?
just unplug car charger from power bank and connect the adaptor to battery pack you are done
but don't charge for more than 3 hours
and just keep checking voltage while charging until it reaches 12 volt .
