Traveling overseas. Need to charge my e cig which i normally charge thru a usb adapter plugged into an iphone charging block

Is it safe to charge it like this when the power is 220? Will my e cog get fried or does the charging block regulate the current output?

If you are using a standard USB charger… They are all 100-240v
People (esp iPhones) expect to charge their phones everywhere they travel. Business people especially

go look on it. It will say something like 100-240vac
100v Japan
115v USA
127v Canada
officially 230v Europe (mainland 220v, UK 240v)
220v China, most of the rest of the works

The charging block always changes to 5v out

Hi Most power plugs are no switch mode which can deal with voltages from 100 volts ac to 240 volts ac.
