I live in Portugal voltage is 220v. I'm traveling to a country where voltage is

[Bruno L]

100v.? How can I recharge electronic equipment battery without damaging it?
Thanx

Correction is not 100v it's 110v!

some equipment will recognise the different voltage automatically, check the user guide

if the batteries are removable, eg AA batteries, then just buy or borrow a charger when you get there

you can get a plug-in transformer which converts voltages - you need to buy that here in europe
