Plugs & voltage
United States uses Type A / B sockets at 120 V. Check your devices say 100–240 V before you plug them in: most chargers do, but hair dryers and straighteners often don't.
Your dates, your list
Tell Stowr when you are going to San Francisco and who is coming. It builds the list from the climate for those exact dates, counts what you can wash on the way, and checks the weight against your baggage allowance.
