Help with travel adapter and voltage?
I bought a travel adapter (not a voltage converter, just a simple adapter) and it says "Suitable for small appliances and portable electronic equipment up to 1430w on the 110v system & up to 2990w on the 230v system."
I know that USA typically uses the 110v system and that my iPhone adapter (wall plug) is suitable for 100v-240v, but the travel adapter says maximum 230v.
Can I use it safely because my iPhone charger is dual voltage or is it unsafe because it goes up to 240v?
Yes, it's OK. "230 volt system" really means about 220-240 volts.
As long as it plugs in at both ends properly, the voltage is not an issue.
It's complicated.
Short version: you'll be ok.
Longer version: the nominal mains voltages across the globe vary between 100 and 240 Volts ( with varying permissible tolerances. Your plug adapter is likely rated for 15 Amps at 230V - but it still has to work safely at 253 Volts, which would be the maximum permissible voltage in Europe. I don't think you'll have to worry about the few countries which are using a (nominal) 240 V grid.
- Will I need an electrical/power adapter to travel to England? (I live in Canada)? I'm traveling to England next summer to visit some family for a month and I was wanting to bring my laptop and phone along with me. I have a Sony Vaio and iPhone 4 (I don't know if that makes a difference at all). If I need to get one, what type do I buy and where can I purchase one? Preferably not online.
- When I unlock my iphone can I use a prepaid SIM card when I travel? I live in Germany and a friend sold me her iphone 3gs when her contract was up. She said the phone would be unlocked after a certain date but it hasn't yet. If i do this myself will I be able to use any SIM card? I have 1and1 for phone service and when I travel to the states I get a prepaid SIM from tmobile. Will these work on the iphone too?
