Frequently Asked Questions

Q: Before buying, how do I know whether it will fit the sockets at home?
A: Check the socket location: if there are twin sockets side by side, a switch directly above, a raised surround around the socket, or the socket is near the edge of a wall, the thick plug body may hit the surround and may not sit flush. It may also cover the switch. It is best to measure the available space before buying.

Q: The plug won't fit into the socket. Is the product defective?
A: No. There is nothing wrong with the plug; the issue is the socket placement. Any thick plug will get blocked in these positions. Use a power strip with local safety certification to separate the plugs, and it will work.

Q: What should I注意 when using a power strip?
A: Choose a power strip with overload protection and local safety certification (for example, choose SAA／RCM certification in Australia／New Zealand). Plug the product directly into the power strip, do not connect one power strip to another, and leave enough space for heat dissipation.

Q: What can I use instead if I don't want to add a power strip?
A: Consider a compact GaN charger. It is much smaller and can fit in narrow socket spaces. Keep travel adapters for use when travelling; hotel sockets are generally more spacious 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 slider should I use for Japan / the US / Australia / the UK?
A: Slide according to the labels: USA = Japan / the US (flat pins); AUS = Australia / New Zealand / mainland China (angled pins); UK = the UK / Hong Kong / Singapore (three rectangular pins); EU = Europe / Korea (round pins). Slide out only one type at a time; slide out the pins before plugging in, and retract them before unplugging.

Q: Is this also a voltage converter?
A: No. A travel adapter only changes the shape of the pins; it does not change the voltage - a 110V-only appliance (such as some US hair dryers) will burn out when used in a 220V region. Most modern phone / computer / camera chargers support 100–240V universally (check the fine print on the device); confirm before use.

Q: Can the AC outlets and USB ports be used at the same time?
A: Yes, each port supplies power independently, but the combined load must not exceed the total power limit marked on the unit. When using the USB-C high-wattage port to power a laptop, we recommend plugging other high-power devices into separate outlets. See the specifications table for the exact combination limits for each model.

Q: Why are there two fuse slots on the back of the unit?
A: One holds the fuse in use, while the other is a SPARE FUSE. If the fuse blows due to an overload, use a small screwdriver to open the compartment and replace it with the spare. If it blows again after replacement, the load is too high - 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 plug setting on the back can be temporarily used with Hong Kong sockets. However, travel adapters are designed for travel, and some models carry a label on the back stating “Not designed for connection to Hong Kong power outlets” - for long-term home use, please use a standard plug adapter or power strip.

Q: Can I take it on a plane?
A: Yes. A travel adapter itself contains no battery, so it is allowed in both carry-on and checked luggage. Note that it is different from a “power bank / portable charger” - those contain batteries and may only be carried in hand luggage, 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.
