All of my electronics can handle 220V. Would it be safe to plug them into a US power strip and use only one adapter? Can I use a surge protector?

I'm not exactly sure of what you're asking, but see if this answers your question:
If you have electronics from North America that require 110v/60Hz A/C, check the label either on the product itself or on the power cord. If the label reads that it can use 220v/50Hz, then you can use that device w/out a power bar or converter.
With power bars, do pay for a good one (I usually pay 80-120 RMB) that has a surge protector (a fuse that will pop out in the event of a surge). Be careful of over-loading the power bars! I used a power bar to power an electric hot water heater in my kitchen, and the darn thing actually started melting! Turns out that the hot water heater can only be plugged into an industrial socket high on the wall.
Another alternative (especially for computers) is to buy a UPS (Universal Power Supply) available at any computer market. These are heavy-duty batteries (thus VERY heavy) but they will prevent surges in current and can last anywhere from 10 minutes to hours depending on the model) if the power goes out in your home/office.
the power bars in China come for different amperages, a 10 watt is OK for charging your phone,,, for a water heater or hotplate, you'd need 30 or more amperage.
Two months ago, I bought AOC Power adapter and it's for 220V. But I never faced any problem..............
