Frequently Asked Questions

Q: Before buying, how can I tell whether it will fit the sockets in my home?
A: Check the socket layout: twin sockets side by side, a switch directly above, a raised surround around the socket, or a position near the edge of a wall. A full-size plug may hit the surround, preventing it from sitting flush, and may also block the switch. It is best to measure the available socket space before buying.

Q: The plug will not go in. Is the product faulty?
A: No. There is nothing wrong with the plug; the issue is the socket layout. Any full-size plug may get blocked in these positions. Use a power board with local safety certification to separate the plugs and solve the problem.

Q: What should I pay attention to when using a power board?
A: Choose one with overload protection and local safety certification (such as SAA/RCM certification in Australia/New Zealand). Plug the adapter directly into the power board, never daisy-chain power boards, and leave enough space for heat dissipation.

Q: I would rather not use a power board. Are there any alternatives?
A: Consider a slim GaN charger. It is much smaller and fits in tight socket spaces. Keep the travel adapter for trips, as hotel sockets are generally wider and less likely to be obstructed.

Q: Before buying, how do I know it fits my sockets at home?
A: Look at the socket spot: twin sockets side by side, a switch directly above, a raised surround, or a position near a wall edge - a full-size plug body will hit the surround and may not sit flush, and can cover the switch. Measure the space before buying if unsure.

Q: The plug will not go in - is the product faulty?
A: No. The plug itself is fine; it is the socket placement - any full-size plug jams in those spots. A certified power board with space for each plug solves it.

Q: Anything to watch out for with power boards?
A: Choose one with overload protection and local safety certification (e.g. SAA/RCM in Australia/New Zealand); plug the adapter directly into the board, never daisy-chain boards, and leave room for heat dissipation.

Q: I would rather not use a power board - any alternatives?
A: Consider a slim GaN charger - much smaller and fits tight spots; keep the travel adapter for trips, where hotel sockets usually have more room.

Q: Which switch should I use when travelling to Japan / the United States / Australia / the United Kingdom?
A: Push out the switch and check the indicator label: USA switch = Japan / the United States (flat pins); AUS switch = Australia / New Zealand / Mainland China (angled pins); UK switch = the United Kingdom / Hong Kong / Singapore (three rectangular pins); EU switch = Europe / South Korea (round pins). Push out only one switch at a time. Extend the switch before plugging in, and retract it before unplugging.

Q: Is this also a voltage converter?
A: No. A travel adapter only changes the shape of the pins; it does not convert the voltage. Using a 110V-only appliance (such as some US hair dryers) in a 220V region may cause it to burn out. Most modern phone, computer and camera chargers support 100–240V universally (check the small print on the device), so confirm the voltage before use.

Q: Can the AC outlets and USB ports be used at the same time?
A: Yes. Each port is powered independently, but the combined total must not exceed the maximum rated power printed on the device. When using the high-wattage USB-C port to charge a laptop, it is recommended to plug other high-power loads into separate outlets. See the specification table for the detailed combinations for each model.

Q: Why are there two fuse slots on the back?
A: One is the active fuse, and the other is the SPARE FUSE. If the active fuse blows due to an overload, use a small screwdriver to open the cover and replace it with the spare. If the replacement blows as well, the load exceeds the limit—do not use a higher-wattage fuse.

Q: Can I use it every day at home in Hong Kong?
A: It depends on the model: models with a UK pin mode can be plugged into Hong Kong sockets for temporary use. However, travel adapters are designed for travel, and some models carry a sticker stating that they are not designed for connection to Hong Kong mains sockets. For long-term home use, please use a regular charger.

Q: Can I take it on a plane?
A: Yes. A travel adapter has no battery, so it is allowed in both carry-on and checked luggage. Note that this is different from a power bank or portable power supply—those contain batteries and are allowed in carry-on luggage only, not checked luggage.

Q: Which slider for Japan / the US / Australia / the UK?
A: Slide per the label: USA = Japan/US (flat pins); AUS = Australia/NZ/mainland China (angled pins); UK = UK/Hong Kong/Singapore (three rectangular pins); EU = Europe/Korea (round pins). Slide one at a time; slide out before unplugging.

Q: Is this also a voltage converter?
A: No. A travel adapter only changes the pin shape, not the voltage - a 110V-only appliance (like some US hair dryers) will burn out on 220V. Modern phone/laptop/camera chargers are mostly 100-240V universal (check the fine print on the charger) - confirm before use.

Q: Can the AC socket and USB ports be used at the same time?
A: Yes - each output is independent, but the total must stay under the rated maximum printed on the body. When charging a laptop on the high-wattage USB-C port, keep other heavy loads off. See the model spec table for combinations.

Q: Why are there two fuse slots on the back?
A: One is the active fuse, the other is the SPARE FUSE - if it blows from overload, swap in the spare with a small screwdriver. If the new one blows too, the load is over the limit - do not fit a higher rating.

Q: Can I use it daily at home in Hong Kong?
A: Depends on the model: with a UK pin mode it fits Hong Kong sockets for occasional use; but travel adapters are designed for trips, and some models carry a sticker saying they are not designed for Hong Kong mains sockets - for everyday home use, use a regular charger.

Q: Can I take it on a plane?
A: Yes. A travel adapter has no battery, so it is fine in both cabin and checked luggage. Note the difference from power banks - those contain batteries and must go in cabin baggage only.
