Travel Adapters: Your Questions, Answered
What Type of Adapter Do You Need?
There are 15 plug types in use across the world. Universal adapters tend to cover all of these types.
- Type A and Type B are used in the US, Canada, Mexico, and Japan.
- Type C is common across Europe, South America, and Asia.
- Type E and Type F are found across Europe in places like Germany, Russia, and France.
- Type G is used in the United Kingdom, Ireland, and a handful of other places.
- Type I is used in Australia, New Zealand, China, and Argentina.
Some countries are not usually covered by universal adapters, such as India (Type D), Israel (Type H), and South Africa (Type M or N). You’ll need to buy specific plug adapters for those places. To avoid any surprises when you land, double-check what type you need before you travel.
If you’re visiting just one destination, a basic plug adapter that caters to one plug type is all you need. For trips to multiple destinations or for frequent flyers, a universal travel adapter can prove more versatile. The universal adapters I recommend here have the bonus of including multiple USB ports for charging several mobile devices from a single outlet.
Do You Really Need a Voltage Converter?

Voltage converters are big, heavy, and expensive, and they don’t always work, so it’s probably best to avoid them. The reason you might think you need one is that the AC sockets on all of our recommended travel adapters do not convert the voltage coming from the socket. This means plugging into a UK socket will deliver 220 volts at 50 hertz, which is very different from the 120 volts at 60 hertz you can expect in the US. Don’t worry! Your gear won’t get fried. You just need to make sure anything you plug into one of these universal travel adapters has something like this printed on it:
Input: 100–220V 50/60Hz
That should include most modern gadgets. If your device or charger can’t handle a variable voltage, it’s probably best to leave it at home. Most places provide hair dryers, irons, and kettles, so there’s no need to take them with you. It’s often cheaper to buy a set with the correct plug at your destination and save the luggage space and hassle.
If you are determined to try a voltage converter (again, I recommend you don’t), the Ceptics 2,000-watt Travel Voltage Converter ($70) seems to work well. It has a special 2,000-watt outlet for hair dryers, but only ones that work via a mechanical switch (anything with an electronic circuit board for automatic switch-off or temperature control won’t work and is at risk of being fried if plugged in). It also has two outlets that go up to 200 watts, one USB-C port, and three USB-A ports, though the ports do not support fast charging.
Can Travel Adapters Go in a Suitcase?
Can I Buy Travel Adapters at the Airport or Hotel?
You certainly can buy travel adapters at the airport, but like everything else, they will be far more expensive than they should be, and your choice will be limited.
Some hotels have travel adapters, and some even have outlets for other countries (or USB-A and USB-C ports), but most do not, so don’t bank on it. You can always check with your hotel or accommodation before you depart, but it’s safer to snag a travel adapter to take with you.
Test Your Travel Adapter Before You Go
Seriously, nothing is worse than thinking you’re being very clever by packing light and getting to your hotel to discover that your gadgets refuse to charge. Between the adapter, cable, and your device, plenty can go wrong, so do a quick test with everything you are taking before you set off.
More Travel Adapters We’ve Tested
There are many travel adapters out there. These are a few others I tested and liked, but they missed out on a place above for one reason or another.
Baseus 70W Universal Travel Adapter With Retractable Cable for $50: This excellent travel adapter is almost identical to our top pick from Ceptics, offering up to 70 watts, sliding prongs to cover more than 200 countries, and a built-in retractable USB-C cable, not to mention a USB-C port and two USB-A ports. It also has a snazzy black and yellow finish. It only misses out because it’s slightly more expensive, but if you can snag one on sale or prefer the colors, it’s a solid option.
Rolling Square Pocket Travel Adapter for $30: I admire any attempt to shrink travel adapters down, but the three-pronged UK plugs are usually the hitch. Rolling Square’s solution is to have a flip-out third prong, but you’ll need a good fingernail to unhitch it. This charger has a single USB-C port capable of delivering up to 30 watts, and it’s a compact option that covers you for the US, UK, and Europe.
Epicka Hybrid European Travel Plug Adapter for $20: This handy adapter turns one outlet into four and includes four USB ports (two A and two C). It has fold-out Type A prongs, but you can also slide on a fold-out Type C plug for use in Europe. While the USB ports support QC 3.0 or PD 3.0, they max out at 20 watts in total. I prefer the OneBeat adapters recommended above, but this is a decent gadget.
EZQuest WorldTravel GaN 5 Port With PD Wall Charger for $35: This travel adapter has a generous four USB-C ports and one USB-A port with a familiar slide-out prong design that covers more than 150 countries. There’s also a built-in 10-amp fuse and a spare. It has RoHS, CE, and FCC certification. It works fine, but it’s kinda boxy, and the sliders don’t lock in place as securely as some of our other picks. There’s also a 65W version ($60).
Epicka Universal Travel Adapter for $18: Our budget pick for many months, this travel adapter from Epicka is still a solid option. The sliding plugs cover 150 countries, and there are four USB-A ports on the bottom and a 15-watt USB-C port on the side. There’s also an 8-amp fuse with a spare, and this adapter is certified by RoHS, CE, and FCC.
Ceptics 65W World Travel Adapter for $35: This versatile adapter comes with Type A, B, C, E/F, G, and I slide-on plugs. They fit onto the rectangular brick and plug directly into the outlet, or you can attach them to the optional 5-foot cable. The brick has one grounded US outlet and a second non-grounded outlet, with one USB-A (30-watt) and two USB-C (65 and 33-watt) ports at the other end.
Masterplug Visitor to UK Travel Adapter (3 Pack) for £12: For visitors to the UK, this simple trio of adapters accepts European, American, Australian, and Asian plugs. They are single-outlet adapters with 13-amp fuses inside, and they work perfectly. These are the adapters I use for long-term testing of devices from the US and elsewhere that lack UK plugs. If you forgot to buy an adapter before you arrived in the UK, you can find this affordable three-pack at any Argos.
Anker European Travel Plug Adapter for $16: One of our favorite portable charger brands, Anker, also makes travel adapters. This one plugs into most European outlets to give you a single grounded US outlet, a USB-A, and two USB-C ports. Unfortunately, the three USB ports max out at 15 watts total, so it’s best for overnight gadget charging, but I appreciate the temperature and overload protection. There is also a UK version ($16).
Ceptics Travel Power Strip for $35: Much like the World Travel Adapter Kit 2 above, this small power strip offers two grounded US outlets, but it has only one USB-A and one USB-C port, and instead of plugging directly into the wall a cable attaches to an interchangeable plug head with Type A, B, C, E/F, G, and I adapters. The adapters can be stiff to change, but they work well otherwise.

OpenAI and chipmaker AMD sign chip supply partnership for AI infrastructure

Semiconductor maker AMD will supply its chips to artificial intelligence company OpenAI as part of an agreement to team up on building artificial intelligence infrastructure, the companies said Monday.
OpenAI will also get the option to buy as much as a 10% stake in AMD, according to a joint statement announcing the deal. It’s the latest deal for the ChatGPT maker as it races to beef up its AI computing resources.
Under the terms of the deal, OpenAI will buy the latest version of the company’s high performance graphics chips, the Instinct MI450, which is expected to debut next year.
The agreement calls for supplying 6 gigawatts of computing power for OpenAI’s “next generation” AI infrastructure, with the first batch of chips worth 1 gigawatt to be deployed in the second half of 2026.
AMD also issued OpenAI with a warrant allowing the AI company to buy up to 160 million shares of AMD’s common stock. That amounts to about 10% of company based on AMD’s 1.6 billion outstanding shares. The warrant will vest based on two milestones tied to the amount of computing power deployed, as well as unspecified “share-price targets.”
Shares of AMD spiked 25% before the opening bell Monday. Shares of Nvidia, which have repeatedly set new record-highs this year, fell slightly.

“This partnership is a major step in building the compute capacity needed to realize AI’s full potential,” OpenAI CEO Sam Altman, said in a news release. “AMD’s leadership in high-performance chips will enable us to accelerate progress and bring the benefits of advanced AI to everyone faster.”
The deal is a boost for Santa Clara, Calif.-based AMD, which has been left behind by rival Nvidia. But it also hints at OpenAI’s desire to diversify its supply chain away from Nvidia’s dominance. The AI boom has fuelled demand for Nvidia’s graphics processing chips, sending its shares soaring and making it the world’s most valuable company.
Last month, OpenAI and Nvidia announced a $100 billion partnership that will add at least 10 gigawatts of data center computing power.

As the Right Leans Into ‘Warrior’ Culture, Some Leftist Gym Bros Are Pushing Back

Last week, “Secretary of War” Pete Hegseth called America’s troops fat. Every “warrior,” he said, will now be required to train every duty day and pass fitness tests twice a year. “Frankly, it’s tiring to look out at combat formations … and see fat troops. Likewise it’s completely unacceptable to see fat generals and admirals in the halls of the Pentagon.”
Equating physical appearance with battle-ready fortitude has become a consistent talking point for Hegseth and other Republicans in his orbit. In August, Hegseth and US health secretary Robert F. Kennedy Jr. launched the “Pete and Bobby Challenge” across their social media feeds, completing a workout of 100 pushups and 50 pull-ups, with the goal of finishing in under five minutes. (Within hours of its publication, left-wing accounts began making fun of Kennedy’s pull-up form and questioning his decision to wear denim while exercising.)
After the young male vote flipped toward Trump by almost 30 points in the last election, the fight for their attention has taken center stage in the US political culture war. Both parties are vying for the male half of the most fitness-obsessed generation in recent memory.
Though there is nothing inherently right-wing about lifting weights, fitness influencers have been at the forefront of the rightward shift of young men in recent years; exercise content represents a key bloc of the so-called manosphere. However, a small but rapidly growing subset of progressive gym bros are moving into the online fitness space, and influential figures on the left are taking notice.
Colin Davis, a 24-year-old from North Carolina, is one of those men. In a series of videos shared to TikTok and Instagram, Davis flexes under dim lighting that accentuates his massive biceps and showcases dumbbell bench presses to heavy metal music. He also posts about his leftist beliefs.
“You don’t need a side hustle, you need a union,” Davis captions one video that has almost 60,000 likes. In a TikTok post that has been liked over 187,000 times, he discusses the legacy of Martin Luther King Jr. and the value of political protest, while leaning on a squat rack
Davis first went viral in April when he published a video of himself seated in a lawn chair in the middle of the woods, ridiculing the “warrior” culture that has grown to dominate much of the male-oriented fitness space. “You are not a warrior, you are not a protector, you are not defending your homeland. You are a guy that lifts weights a couple times a week and maybe goes for a run,” he says, staring into the camera deadpan.
Though the aesthetic similarities can be undeniable, Davis’ content is a stark departure from the deluge of “trad” fitness that inundates many young men’s Instagram and TikTok feeds. Those often include compilation videos of men flexing their muscles, cut between clips that ridicule partying women, body-positivity influencers, and gay men. “Embrace Masculinity,” one such video emblazons across the center of the screen.

Competition heats up to challenge Nvidia’s AI chip dominance

The artificial intelligence (AI) revolution has whetted the appetites of Nvidia’s competitors, who are seeking to close the gap on the chip giant, which has so far been the central playmaker in the AI revolution.
Virtually unknown to the general public just three years ago, Nvidia now boasts the world’s highest revenues, driven by sales of its graphics cards—or GPUs (graphics processing units)—the processors that are key to building the technology behind ChatGPT and its rivals.
Why does Nvidia dominate?
While it was not the first to develop GPUs, the California-based group made them its specialty starting in the late 1990s, at the very beginning of cloud computing, and thus has unique experience in the field.
Moreover, Nvidia is “a three-headed dragon,” as Dylan Patel, head of consultancy SemiAnalysis, recently put it on the “No Priors” podcast.
It does not just design chips, but offers an entire infrastructure capable of making them work together with networking and software—the dragon’s two other heads.
Nvidia can “satisfy every level of need in the datacenter with world-class product,” according to Jon Peddie of Jon Peddie Research.
Where is the competition?
At a considerable distance from Nvidia, whose market share is estimated at roughly 80% depending on the source, American firm AMD had until now been considered the runner-up.
But AMD generates the bulk of its revenue from CPU sales—processors used for personal and business computers that are less powerful than GPUs—and “can’t divert resources from that golden egg,” Peddie believes.
Determined to reduce their dependence on Nvidia, the major cloud providers have developed their own processors.
Google began using its Tensor Processing Unit (TPU) a decade ago, while Amazon Web Services (AWS)’s Trainium, the cloud-dedicated subsidiary, appeared in 2020.
Today, Google and Amazon account for more than 10% of the market and have even overtaken AMD in terms of “performance, pricing, usability, reliability, and ability to produce enough chips to satisfy the biggest customers,” argued Jordan Nanos of SemiAnalysis.
Google is even offering its chips to third-party customers, according to several media reports. Contacted by AFP, it did not respond. Amazon, however, does not sell its Trainium to other players.
Where do the Chinese stand?
The only nation rivaling the United States in the sector, China is seeking to make up for lost time—and is having to do so without the most advanced US chips, which are now subject to export restrictions.
For Nanos, Huawei ranks among Nvidia’s most credible competitors, alongside Google or Amazon, and ahead of AMD.
Like Google and Amazon, their Chinese equivalents Baidu and Alibaba are also now having their own AI processors manufactured, though these remain merely substitutes for Nvidia’s GPUs.
“They can’t catch up technically for a while using in-country” fabrication facilities, said Peddie.
But “over time, with its huge and smart workforce, and subsidized investment, China will be able to make state-of-the-art fabrication systems.”
Is Nvidia under threat?
No expert sees the Santa Clara, California, giant loosening its grip on the sector in the near future.
“Nvidia underpins the vast majority of AI applications today,” notes John Belton, analyst at Gabelli Funds. “And despite their lead, they keep their foot on the gas by launching a product every year, a pace that will be difficult for competitors to match.”
In early September, Nvidia announced that its new generation, Rubin, would be commercialized in late 2026, with performance for AI functions estimated at 7.5 times that of its flagship product currently on the market, Blackwell.
