Travel adapter for MacBook Pro Charger (USB-C Power Adapter)
Use a plug adapter only after confirming that your actual input rating covers the local voltage and frequency. Match your real plug and preserve any required grounding. An adapter does not change voltage.

Buying criteria
- If your device has a three-pin (grounded/earthed) plug, use a grounded adapter that keeps the earth connection. Don't force a three-pin plug into a two-pin adapter or defeat the earth pin — the ground is a safety feature that protects against electric shock.
- Check AC input, USB-C protocol, cable and per-port output. Read the shared output limit when several ports are used.
- Category baselines and charger OUTPUT examples are not measured AC consumption or approval for your unit. Confirm actual INPUT/load and the required charging protocol, voltage, current and per-port mode with the manufacturer.
Check the label
- Compatibility is unconfirmed. Read the exact INPUT voltage range and frequency on your device or power supply, and compare them with the destination. The whole local range must be covered; 110–220V does not include 100V or 230–240V. Confirm the actual plug, grounding and manufacturer restrictions. Do not plug in while these details are unknown.
- Read the INPUT rating on the exact device or AC supply: V = voltage, Hz = frequency, A/W = current/power. USB/DC OUTPUT ratings are not the AC input range or measured wall consumption. Match the full local voltage and frequency, plug, grounding and manufacturer instructions. A 100–240V label covers only that range; 120–240V does not include Japan’s 100V. If the label is missing or unclear, do not connect until confirmed.
What to avoid
- An adapter changes plug fit only; it does not change voltage or frequency. Do not connect an incompatible supply. Follow the exact device and power-supply manufacturer instructions; a converter is not automatically permitted.
What to avoid
- Adapters that run hot, fit loosely or lack a clear electrical rating.
- “All-in-one” boxes that imply a plug adapter changes voltage.
- Chargers that do not meet your device’s wattage and charging-protocol requirements.

A source supports only the facts, socket types or models listed below. A model example does not verify every device in its category. Confirm your own label and outlet.
- SKROSS: Can adapters convert voltage? · checked: 2026-09-04
A passive plug adapter changes the connection, not the mains voltage. Check the device nameplate. Answer paragraphs 1–2. Manufacturer guidance for its adapters; this does not approve a voltage converter for a particular appliance.

Two-pole and three-pole appliance support differs between adapter families. Choosing by appliance type: MUV versus three-pole adapters. A universal marketing label does not establish earth continuity. Check the exact adapter, appliance plug and socket.
- SKROSS: World to USB series manual, version 1.2 · checked: 2026-09-04
AC current limits and USB output are separate. In the AC20PD examples a single USB-C port reaches about 20W; simultaneous USB-A + USB-C use shares 15W. PDF page 1, English technical ratings and safety instructions. These figures apply to the named series. The manual prohibits stacking adapters and multiplug sockets; other models require their own manual.

FAQ
Does a MacBook pro charger (USB-C power adapter) need an adapter or a converter?
Use a plug adapter only after confirming that your actual input rating covers the local voltage and frequency. Match your real plug and preserve any required grounding. An adapter does not change voltage.
Can I charge a MacBook pro charger (USB-C power adapter) with a GaN USB-C charger?
Check AC input, USB-C protocol, cable and per-port output. Read the shared output limit when several ports are used.
What's the safest adapter for a MacBook pro charger (USB-C power adapter)?
Check the exact destination sockets, incoming plug and continuous grounding. A universal adapter may omit a country or accept only two-pole appliances.
Guidance only — not professional electrical advice. Always confirm against your device's label before plugging in. Local wiring (especially in hotels and older buildings) can vary.
