We don’t review many solar panels at The Verge, but the tech inside Bluetti’s incredibly portable Sora 500 panel makes it worth a deeper look. The new N-Type panels made by Bluetti and others give you more bang for the buck, pound, and square inch. That’s a big deal for vanlifers like me who depend upon these beefy portable solar panels to extend off-grid stays.
Technology
Bluetti’s Sora 500 solar panel is incredibly powerful for its size
In real-world testing, I saw Bluetti’s 500W panel deliver 509W to my van’s power station, allowing me to generate over 800W when combined with the three sad 140W monocrystalline solar panels I have installed on top of my van. That kind of stationary output is fantastic. I typically consume about 1.6kWh a day, so this array lets me add a full day’s worth of charge in only two hours. I just wish that Bluetti had made the Sora 500 bifacial like Jackery and newcomer Zoupw did with their even lighter, high-wattage, portable, N-Type panels designed to maximize output in less than ideal conditions.
The Sora 500 is priced at €849 in Europe — it isn’t being sold in the US yet. Bluetti spokesperson Ellen Lee tells me that the company wants to bring it to the US market but it’s “currently navigating some shifting regional policies and trade dynamics.” Things that Zoupw and Jackery managed to sort out already.
$984
The Good
- Incredibly compact when folded
- Good performance in partial shade
- Exceeded rated output
- Efficient N-Type TOPCon cells
The Bad
- Heavy compared to competitors
- Single-sided (not bifacial)
- Tedious to unfold/pack
- Not yet available in the US
Bluetti’s single-sided Sora 500 panel uses TOPCon (Tunnel Oxide Passivated Contact) cells, an N-Type technology which is replacing older PERC (Passivated Emitter and Rear Cell) tech. Compared to PERC, TOPCon panels do better in low-light, deal with high temperatures better, and degrade more slowly. TOPCon panels can achieve higher efficiencies (often ~23–25 percent) compared to typical PERC panels (~20–23 percent), depending on implementation.
All these advantages mean that you’ll get more for your money, as soon as you unfurl all 12 panels of the Sora 500 and over their extended lifetime. The panel also features an IP67 resistance to dust and water and an ETFE coating that makes it easier to wipe away dirt that interferes with solar intake.
In my mid-March testing in the south of France at an altitude of about 600 meters, I was regularly seeing the Sora 500 delivering above its rated output, measuring as much as 509W on a cool and cloudless day. It also does a good job of handling the sun being partially shaded.
For example, on a very sunny day when the 12 individual panels that comprise the Sora 500 were producing over 500W, the output dropped to 412W when partially shading one corner panel, and 390W when partially shading the right-most two. Partially shading the four panels just to the right of center dropped the output to 276W.
The output from the Sora 500 dropped dramatically when I blocked the center four panels, falling to just 50W. That’s likely because I choked off the entire array by severing the connection between all four parallel zones. Bluetti uses a half-cut cell design and a 3-series, 4-parallel (3S4P) circuit architecture for the Sora 500. This results in multiple independent power zones by dividing the cells into smaller halves and distributing them across four parallel power paths. It helps to prevent a single shaded area from becoming a bottleneck for the entire panel, like you see with cheaper panels.
Unfortunately, Bluetti chose to cover the back of its panels with fabric and a complex system of kickstands and straps. By comparison, the Zoupw 480W and Jackery SolarSage 500 X N-Type panels are bifacial, meaning they can also collect ambient light from the back of the panels when placed on reflective surfaces like snow, sand, concrete, and, to a lesser extent, grass.
I haven’t tested these panels myself, but I’ve seen unconfirmed user reports claiming to have pushed the Zoupw beyond 525W of output. Importantly, both panels also weigh just 22lb (10kg), making them even lighter than the 28.4lb (12.9kg) Bluetti Sora 500.

| Bluetti SORA 500 | 500W | 28.40 lbs | ~4,510 sq in (100.0” x 45.1”) | 17.61 W/lb | 0.110 W/sq in |
| Jackery SolarSaga 500 X | 500W | 22.05 lbs | ~3,848 sq in (98.1” x 39.2”) | 22.68 W/lb | 0.130 W/sq in |
| Zoupw 480W | 480W | 22.49 lbs | ~4,512 sq in (138.6” x 32.6”) | 21.34 W/lb | 0.106 W/sq in |
And while weight is an important enabler of portability, I should note that these things tend to fly away when the wind picks up. Fortunately, the Bluetti panel I’ve been testing has tie-down points for gusty days. All three panels are much lighter than the reliable 400W PERC monster from EcoFlow that I’ve been hauling around for the last four years. It weighs 35.3lbs (16kg) and is still available to buy for $599.
For vanlifers, the Bluetti Sora 500 absolutely dominates when it comes time to pack the panel away into an RV, van, or closet. The Zoupw and Jackery use standard 4-section or 6-section “slab” folds, while Bluetti uses a 12-section grid fold, allowing it to collapse into a much smaller, briefcase-like package. Even then, the 3.3-inch thick folded Bluetti is thinner than both the 3.35-inch thick Zoupw panel and 3.82-inch Jackery.

|---|---|---|---|---|
| Bluetti SORA 500 | 500W | 22.4” × 17.5” | 392 sq in | 1.28 W/sq in |
| Jackery SolarSaga 500 X | 500W | 39.2” × 20.7” | 812 sq in | 0.62 W/sq in |
| Zoupw 480W | 480W | 34.7” × 32.6” | 1,131 sq in | 0.42 W/sq in |
Conversely, the Sora 500 can be a pain in the ass to set up due to all the hinges and straps needed to support so many segments. It’s a puzzle I managed to mostly master after the third installation, but repositioning the panel to follow the sun throughout the day is a lesson in patience.
1/8
Without official US pricing for the Sora 500 panel, it’s hard to do a direct price-per-watt comparison with the $649.99 Zoupw 480W and $999 (often on sale for $799) Jackery SolarSage 500 X. However, if we strip the European VAT from its €849 price tag and convert it, the Sora 500 works out to about $820. While that’s competitive, it still leaves the Zoupw 480W with the best price-per-watt performance in this class.
Bluetti’s Sora 500 can’t compete with the Zoupw 480W and Jackery SolarSage 500 X in terms of weight, but it wins handily in terms of Watts per square inch when folded down. It’s the only 500W panel that effectively disappears into a small closet or under a van bench. As such, it justifies its price premium for anyone like me who has limited space to store an extra solar panel they only need to deploy occasionally.

Atlantic reporter Alex Reisner recently uncovered four datasets of music being used to train AI models and made them fully searchable for the public. Two of the sets are absolutely enormous at 12 million and 9 million tracks. The other two are much smaller, but still represent a significant amount of training data at over 100,000 songs each.
According to Reisner, the sets have been downloaded thousands of times and, while it’s impossible to know exactly who has used them, Google and Stability have both confirmed they have in research papers. Some of the sources, like the Free Music Archive dataset, are free to stream for personal use but require licensing for commercial applications.
While the datasets are freely available on the internet in theory, using them as training data is not as simple as downloading a ZIP file and feeding it to an AI model. As Reisner explains:
Three of the datasets I found are distributed as a list of links to songs on YouTube or Spotify. AI developers download the actual audio using tools that automate the job, some of which allow developers to bypass logins, advertisements, and mechanisms that might earn money or subscribers for creators. Such tools violate the terms of service of these platforms.

You step off a long flight, find your hotel and the first thing you look for is the Wi-Fi password. You connect, clear your inbox, log into your streaming account to unwind and maybe check your bank balance before dinner. It all feels harmless because we all do it.
But that one travel habit can quietly put your passwords, accounts and personal information at risk.
Public Wi-Fi is convenient for you. It can also be convenient for the person sitting three tables over with a laptop and bad intentions.
THE TEMPTATIONS AND RISKS OF FREE WI-FI

Why public Wi-Fi is such a soft target
Most public networks send your data through the air on a network you do not control. When a network is open, anyone connected to it may be able to use simple tools to watch traffic patterns, spot unencrypted activity or try to redirect you to fake login pages. Security researchers call this packet sniffing. Modern HTTPS protects most usernames and passwords, but not every app, site or connection handles security perfectly. That is where public Wi-Fi can still get risky fast.
Then there are the fake networks. A hacker sets up a hotspot named something friendly like “Airport_Free_Wi-Fi” or “Hotel Guest,” and travelers connect without a second thought. Once you’re on their network, everything you do passes through their hands first. This trick is common enough that it has a name: the evil twin attack.
APPLE FIXES PASSWORDS APP VULNERABILITY ENABLING WI-FI ATTACKS
Here’s the part most people miss. Stealing your password is not the only goal. When you log into a service, your device gets a small file called a session token that keeps you signed in. If an attacker can trick you onto a fake network, push you toward a fake login page or exploit a poorly protected connection, that token or login can become a target. That is how a quick hotel Wi-Fi session can turn into someone hijacking an account, locking you out, racking up charges or selling your access on the side.
Your phone, your laptop, your email, your banking app, your streaming logins. On an unprotected network, all of it is fair game.
The simple fix: encrypt everything you send
The good news is that protecting yourself does not require you to become a security expert or swear off public Wi-Fi forever. You just need a Virtual Private Network, or VPN.
ROUTER VPNS VS DEVICE VPNS: WHICH PRIVACY SOLUTION IS BEST FOR YOU?
A VPN builds an encrypted tunnel between your device and the internet. Everything you send and receive gets scrambled before it leaves your phone or laptop, so even if someone is watching the network, all they see is meaningless noise. Your passwords, your messages, your account logins and your banking details stay locked up tight.
The catch with a lot of VPNs is that people either forget to turn them on or find them clunky enough to give up. The best VPN for travel should be easy to use, fast enough for streaming and video calls, strong on privacy and able to protect your devices with one tap.
My No. 1 pick checks those boxes without making you think about it. It uses strong encryption, has a no-logs policy, includes a kill switch if the VPN connection drops and runs on iPhone, Android, Windows, Mac and routers.

A few smart habits to pair with it
A VPN does the bulk of the work, but these quick moves close the remaining gaps.
1) Turn off auto-connect
Stop your phone from automatically joining Wi-Fi networks you do not fully trust.
5 PHONE SETTINGS TO CHANGE RIGHT NOW FOR A SAFER SMARTPHONE
On iPhone, go to Settings > Wi-Fi > Ask to Join Networks and choose Ask or Notify. You can also tap the info icon next to a saved network and turn off Auto-Join.
On Samsung, go to Settings > Connections > Wi-Fi, tap the gear icon next to a saved network and turn off Auto reconnect.
2) Confirm the network name before you connect
Before joining a hotel, airport or café Wi-Fi, ask the staff for the exact network name. Fake “free Wi-Fi” networks often use names that look official enough to fool tired travelers.
3) Turn on two-factor authentication
Even if a password leaks, 2FA gives an attacker another wall to get past before they can break into your account.
4) Use a password manager
Better still, use a password manager to create and store super-secure credentials that are unique for every site.
5) Save the sensitive stuff for trusted connections
When you can, handle banking, shopping and other sensitive logins on cellular data, your phone’s hotspot, your home network or a trusted VPN.
Kurt’s key takeaways
The trip is supposed to be the memorable part, not the security headache you deal with after you get home. The travel mistake is treating free Wi-Fi as safe Wi-Fi. Free Wi-Fi can be risky, and the people who exploit it are counting on you not to notice. Flip the script with a trusted VPN, build the one-tap habit, and you close one of the easiest doors hackers use against travelers.
Do you turn on a VPN the moment you connect to public Wi-Fi, or only when you remember? Let us know by writing to us at Cyberguy.com

From its opening minutes, Moves of the Diamond Hand is upfront about what it offers: You’re going to have a lot of strange conversations, and you’re going to roll a lot of dice. Get on board with this proposition, and the reward is one of the most creative roleplaying games I’ve seen in years, even if its many mysteries won’t be resolved until 2027.
Moves of the Diamond Hand is an Early Access videogame available on PC, macOS, and steamOS (including the Steam Deck, where I played it) from musician and game designer Cosmo D. The game looks and feels like a 2000s-era first-person RPG or immersive sim: environments are grimy, stark, and blocky; characters’ features are stretched over smooth heads a bit too small for their faces; an eerie soundtrack pulses over all. You’ll arrive on a train and immediately meet an old mentor, disgraced by some kind of political scandal. You convey your desire to join a powerful organization called Circus X, then declare which of several wildly different paths you’ll take into its fold — you can try joining the city council, but could find equal success crafting the perfect sandwich or joining the best band.
These options help introduce the central mechanic. The game gives you one upgradeable die for each of seven stats, ranging from standard fare like Physique and Observation to the more idiosyncratic Cooking and Music. To set a challenge, it will roll a die corresponding to one of those attributes, and you’ve got to match or beat it with your own roll.
Once you emerge into the train station, the complexity quickly multiplies. There are a plethora of sub-mechanics including cooking, performing music, laundering disguises, and mixing cocktails — all of which add additional dice with unique quirks. You can selectively re-roll dice in a manner similar to Yahtzee, introducing an element of strategy within each encounter, and your final score (win or lose) is translated into experience points. The basic system was introduced in Cosmo D’s last game, Betrayal at Club Low, but in a less flexible and elegant form; Diamond Hand feels like its evolution. (Disclosure: My husband has provided outside feedback for Cosmo D’s games.)
It’s all a little intimidating at first. But the game allows you to ease into its options, which happens quickly, since you’re rolling for virtually every action and verbal exchange from making small talk to opening a door. There’s a meaningful element of chance to all this, without descending into unbounded randomness. Some rolls can be mathematically impossible to win or lose at a given skill level, but it’s possible to still damage your health or gain an unwelcome status effect with safe challenges, preventing them from becoming purely rote. You can retry most actions if you fail them, but they’ll become slightly more difficult on a second attempt, so there’s a constant balancing act of deciding when to take the initial leap. The ambient low-level risk makes even simple spaces feel substantive and engaging — it negates the common RPG urge to speed through environmental detail and flavor text while looking for the “real” parts of the game.
Through countless skill checks, you’ll internalize the odd logic of the game’s world. The setting, Off-Peak City, is a garish metropolis shaped by the machinations of sinister corporations, corrupt politicians, and shady operatives, but also musicians, restaurateurs, and literally and figuratively underground tailors — a neon retro-future for streetwise aesthetes. What might be niche skills in any other game prove extraordinarily powerful here. The Music stat, whose uses include sewing (machines can, among other options, be literally operated by improvisation), calming aggressive animal-human hybrids (by whistling tunes), and mixology (which can be performed “rhythmically”), is arguably the single strongest power in the game.
Circus X, you’ll soon learn, is a secretive arts institution that influences everything from politics to the sandwich supply chain — imagine the Factory crossed with the Freemasons. While pursuing membership, you’re embroiled in a local election between a scandal-plagued technocrat, a former boy-band star, and the corporate-controlled clone of a mayor from decades past. In place of a Maltese Falcon, everyone’s scheming for control of a sentient Big Mouth Billy Bass. And meddling behind the scenes is the mysterious, anarchic Diamond Hand, frequently alluded to but not explained.
Diamond Hand’s story evokes real-world parallels, but as a jumping-off point for something that’s rich and alive in its own right. In perhaps the most obvious example, a company in Off-Peak City is pumping the place full of clones, supplanting human artists with corporate-guardrailed regurgitations of old media. But rather than stop at commentary, the game walks this out to explore the idea that clones are also conscious beings who are frustrated by their creative limits and lack of autonomy, while letting human characters reflect on their own relationship with nostalgia and artistic taste.
Put this all together and you’ve got a hard-boiled sci-fi thriller involving subway busking, finding library books, stumping for politicians, harvesting lettuce, arguing about jazz, and doing laundry, infused with the lizard-brain appeal of a nonstop game of chance. It’s irresistible.
Most of Diamond Hand’s main quests end in roadblocks, because its Early Access build includes only the first two of six chapters, with the next scheduled for this summer and a full launch set for the spring of 2027. But even in its current state, Diamond Hand is dense and tantalizing, delivering a string of absurd premises and dry humor with a straight face. (Among many tossed-off jokes that are also actual game mechanics, local pizza-makers require everyone to bake their own pie, so if you don’t like your order, you have only yourself to blame.) You’re granted experience points for letting characters ramble through their backstories and opinions — which lands somewhere between a sly gag about RPG infodumping and a straightforwardly clever decision — but the dialogue pays off even without that prize.
And for all its dystopian elements, there’s something idealistic about a world where art, for good or ill, deeply matters. Diamond Hand may be a work in progress, but it’s a recipe for becoming obsessed with skill and perfection, chasing the world’s greatest sandwich and the string of lucky dice rolls that will get you there.
