Travel adapters for Singapore, the UK and Australia: what actually matters (and what does not)
Travel Adaptor Guide · Universal Adapter · GaN Charger · SG / UK / AU 2026
In 30 seconds: if you are going to Singapore, the UK or Australia, a Hong Kong appliance needs an adapter and nothing else - all four places run 220-240V. Singapore and the UK even use the same Type G plug as Hong Kong. The real decision is total wattage: 30-45W for a phone, 65-100W if you carry an ultrabook, 120W and up for a MacBook Pro or several devices at once.
An adapter is not a transformer
This is the most common and most expensive misunderstanding in travel electronics. An adapter changes pin shape. A transformer changes voltage. They are different devices, and buying the wrong one either does nothing or damages what you plug in.
So for Singapore, the UK and Australia, one universal adapter covers the whole trip. For Japan and the US the calculation is different, and hair dryers, kettles and irons are usually a local purchase or a hotel loan rather than something you convert.
Wattage, not port count
A six-port adapter does not deliver full speed to six devices. Every port shares one total. Split 100W three ways and each device sees about 33W.

Five mistakes worth avoiding
1. Buying a UK-only adapter for Australia
A Type G adapter does nothing in Australia - the sockets are Type I, angled pins. Buy universal, which covers Type G, Type I, Type A and Type C.
2. Assuming more ports means more power
Total wattage is the constraint. If you want several devices charging at full speed, buy a higher-wattage unit rather than one with more holes.
3. Plugging a hair dryer into a USB adapter
It will not work. Hair dryers draw 1,200-2,000W. You need an adapter with an AC outlet, and the outlet must be rated for it. Check the printing on the body before you plug in.
4. Charging a laptop through an unbranded universal socket
A universal socket accepts several pin shapes, so the contact area inside is smaller than a fixed socket and sustained current warms it. Fine for a phone overnight; not what you want for a 96W laptop charger running for hours. Buy a branded unit with a fuse.
5. Forgetting the hotel has one socket
Many hotel rooms give you one or two outlets, often under the desk. An adapter with an AC outlet turns one socket into "AC plus four USB", which is more useful than carrying three separate chargers. That is why we suggest prioritising units with an AC outlet over USB-only designs.
Plugs and voltage, for each market
Singapore uses Type G, identical to Hong Kong - nothing changes, plug straight in. The UK is also Type G; the only adjustment is that UK sockets are switched and often have a fuse in the plug, which is a safety feature rather than a compatibility issue. Australia uses Type I, so you need the adapter, but the voltage is the same 230V, so no converter is involved.
Delivery and warranty
Hong Kong: 1-2 working days. Singapore: 5-9 working days. UK: 6-10 working days. Australia: 7-12 working days. All units carry a Hong Kong warranty; overseas buyers ship back to us for service, return freight at your cost, and the round trip takes 2-4 weeks.
Questions we get asked
Does a travel adapter change the voltage?
No. An adapter changes the shape of the pins only. Singapore, the UK and Australia all run 220-240V at 50Hz, the same as Hong Kong, so a Hong Kong appliance only needs an adapter there. Japan (100V) and the US (120V) are different - high-wattage appliances like hair dryers and kettles need a transformer, and often cannot be run at all.
Do I need a dedicated Australian adapter?
No. Buy a universal adapter - it includes the Australian Type I angled pins alongside UK Type G, US Type A and European Type C. A UK-only adapter is useless in Australia.
How many watts do I need for a laptop?
A MacBook Air draws about 30-35W, a MacBook Pro 14" about 96-140W, and most Windows ultrabooks 45-65W. Add 20-30W for a phone, 20W for a tablet, 5W each for a watch and earbuds. A business trip typically totals 100-150W, so a 100W or higher unit means you never take turns.
Do more ports mean more power?
No - and this is the most common mistake. Total wattage is shared across all ports. A 100W adapter with five ports gives roughly 20W each when all five are in use. Buy for total wattage, not port count.
Is GaN worth the extra money?
Yes above about 65W. Gallium nitride switches faster than silicon, so the same output fits in roughly two-thirds the volume and runs cooler. The premium is typically HK$50-100, and for anyone who travels regularly it is rarely regretted.
Are universal sockets safe?
It depends on the build. A universal socket has to accept several pin shapes, so the internal copper contact area is smaller than a fixed socket, and sustained high current makes it warm. Choose a branded unit with an internal fuse, and avoid running a laptop charger through a cheap unbranded one for hours.
Can I plug a hair dryer into it?
Only if the adapter has an AC outlet, and only within its rating. Hair dryers draw 1,200-2,000W, far beyond any USB output. Check the maximum AC wattage printed on the adapter; most are rated 1,500-2,500W. A USB-only adapter cannot power a hair dryer at all.
Is there a warranty?
Yes - all units are Hong Kong stock with a typical one-year warranty. Adapters are passive devices with a low failure rate, but a blown fuse counts as user damage and is not covered.
Before you fly
- Destination socket type confirmed (SG/UK Type G, AU Type I, JP/US Type A)
- Total wattage of everything you are carrying, plus 30% headroom
- AC outlet present if you need to run a hair dryer or an original charger
- Maximum AC rating printed on the adapter checked
- Internal fuse present
- Transformer arranged if the trip includes Japan or the US
- One spare USB-C cable packed
Voltage, frequency and socket types are the published standards for each market. Output wattage, port count and features are taken from product names and manufacturer markings. Hong Kong prices are read live from our product pages; SGD, GBP and AUD are converted at the rate published on 28 October 2026 and exclude shipping, duties and taxes. An adapter does not convert voltage - check the maximum AC rating on the body before connecting any high-wattage appliance.
