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 .

lithium batteries are explosive

please do it on your own risk and responsibility ..
