What's inside
The checklist walks you through the three moments that matter: before you go, at the outlet, and when you pack.
- Before you go
- At the outlet
- Destination reference
- Pack and record
- Sources and limits

Based on what's typical for this device — confirm on the label to be sure.
Travel Electricity Checklist
Do not connect until confirmed
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.
Record the actual outlet and label; a country table is not approval for your device.
| Device / model | Exact INPUT label | Plug / grounding |
|---|---|---|
Pack and record
Destination / Local outlet: __________________________________
Confirmed / unresolved: _________________________________________
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.
At the outlet
An adapter changes plug fit; it does not change voltage or frequency.
A voltage converter is unnecessary only if your charger’s actual INPUT range covers the local supply and frequency, and its manufacturer permits this use. Confirm the exact outlet, plug fit and any required grounding. A typical charger profile does not verify your model.
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.
The watts × 1.25 figure is a PlugVoltage estimate, not a verified converter requirement. Confirm startup demand, permitted loads and duty cycle with both manufacturers. The site does not recommend conversion for mismatched high-power heating appliances.
High-power heating appliances need a correctly rated supply and model-specific instructions. A plug adapter does not fix an electrical mismatch. PlugVoltage conservatively recommends a locally suitable appliance when compatibility is uncertain; a converter estimate is not approval. Follow any manufacturer prohibition on converters and any manual voltage-selector instructions.
For a medical device, confirm the exact power-supply label, approved accessories and travel instructions with its manufacturer. A representative CPAP supply does not verify every machine, humidifier, heated hose or battery. Do not guess with equipment you depend on.
Destination reference
Record the actual outlet and label; a country table is not approval for your device. ?: Exact source pending / Types still unverified
| Destination | Nominal voltage / Frequency | Socket types |
|---|---|---|
| United Kingdom | 230V / 50Hz | G |
| Japan | 100V / 50/60Hz | A / B |
| Australia | 230V / 50Hz | I |
| China | 220V / 50Hz | A / C / I |
| Thailand | 230V / 50Hz | A / B / C / O |
| Philippines | 220–240V / 60Hz | A / B |
| Brazil | 127–220V / 60Hz | N / C |
| Mexico | 127V / 60Hz | A / B |
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.
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.

Philippines
ERC: Amended Distribution Services and Open Access Rules
Scope: Philippines distribution utilities and end-users; nominal service monitoring · Nominal voltage · checked: 2026-09-30
Signed ERC Resolution 02 Series of 2010, PDF pp1–2; p19/printed17 section 1.3 national applicability; p24/printed22 section 1.7.6 requires every DU to adopt 230 V nominal service voltage for monitoring at meter socket/main service entrance. Alternate nominal standards are reportable to ERC. Its 207/253 V monitoring limits do not verify the stored 220–240 range or every outlet. Official Meralco-hosted regulator original, not a utility-territory extrapolation.
ESCAP/WMO Typhoon Committee: Manila TC57 participant information
Scope: Philippines national visitor guidance · Socket types (A/B) · checked: 2026-09-30
PDF p1 author/date; p2 section 8 explicitly names Philippines A/B; p7 PAGASA local organizer. Images cite world-power-plugs.com, not an outlet survey. Its 220 V statement is excluded from the stored 230 V nominal claim; no grounding or guaranteed Type B availability follows.

Thailand
Thailand AM 2026: Type B in hybrid sockets
Scope: Thailand visitor socket guidance · Socket types (B) · checked: 2026-09-30
Plug Types > Type B: two parallel flat pins plus a round grounding pin, supported by hybrid sockets though becoming less common. Narrow Type B support only; verify the actual outlet and earth connection locally. The same page’s 220 V and Type F wording remains candidate evidence and does not change country values or socket arrays.
