“My laptop brick said 100–240V, so I focused on the wall cable and whether it would fit China’s A · I outlets.”

Will my laptop charger work on China’s 230 V supply?
For China, verify the exact laptop equipment instead of relying on a country-level assumption. For a trip based around Shanghai, the wall socket is only half the story; the device label still decides whether 230 V is acceptable. The laptop’s AC adapter should show an INPUT range that includes 230 V and 50 Hz. A label such as 100–240V ~ 50/60Hz normally covers the listed supply.
A North American 120 V-only laptop brick would not become safe just because an adapter lets its plug enter a A · I socket. Modern laptop adapters are commonly wide-input, but the printed label on the exact brick is the evidence that matters. Across different accommodations in China, a tested laptop power setup is easier to repeat.
China power: A · I · 230 V · 50 Hz
See the China power plug guide →Will my laptop plug fit China outlets?
The A · I outlet family answers plug fit for a laptop, not whether it accepts 230 V. China lists A · I. If the laptop charger’s wall plug does not match, use a plug adapter or a compatible detachable AC lead; neither option changes voltage. In Shanghai, a compact plug solution also keeps a heavy power brick from hanging awkwardly from the wall.
EPICKA Universal Travel Adapter — when a laptop plug does not match China
For China, use it only after confirming the laptop charger accepts 230 V; it solves A · I plug fit and does not change the local electrical supply.

A hotel-room workaround in China should not replace checking USB-C PD wattage and port sharing before departure. USB-C changes the packing decision but not the electrical rules. A USB-C charger may accept 230 V and still be underpowered for the laptop. Before replacing the original brick for a China trip, compare USB-C PD wattage, port capability and whether the laptop expects a specific charging profile.
Grounding and detachable laptop cables in China
Testing the complete laptop setup before China keeps the travel-power kit simpler. Grounding deserves a separate look when the original laptop adapter uses a grounded cord. A · I describes the local socket family, but hotel and older-building outlet arrangements can vary. If your power brick uses a detachable cable, a country-compatible grounded lead can be cleaner than stacking adapters.
Anker 735 Charger — a compact USB-C option for a China laptop kit
For a China laptop setup, this is useful only when its INPUT covers 230 V and its USB-C output meets the computer’s charging requirement; check both before relying on it in Shanghai.

Once a converter-free work setup is confirmed for China, extra conversion hardware is easier to avoid. For Urumqi, the simplest workflow is usually: verify the charger input, solve plug fit, then test the full laptop setup before departure. A voltage converter is normally unnecessary when the laptop adapter already accepts 230 V; adding one creates more bulk without improving a compatible switching power supply.
