Fast Charge. Long Play: KIWI design Highlights DualFast Charging in K4 Boost and H4 Boost Head Straps
LOS ANGELES, June 23, 2025 /PRNewswire/ -- KIWI design, a global leader in premium XR accessories, is redefining the VR battery strap experience with its innovative DualFast Technology—now featured in both the K4 Boost and H4 Boost head straps for Meta Quest 3/3S.
Unlike traditional battery head straps that often prioritize capacity over comfort, KIWI design takes a smarter approach. By leveraging fast charging technology, both K4 Boost and H4 Boost maintain a lightweight battery profile without compromising performance. This design philosophy not only enhances comfort but also aligns with the way most users actually play: in sessions that include breaks for rest or hydration.
Quick Top-Ups, No Downtime
The DualFast charging system enables 22.5W simultaneous high-speed charging of both the headset and the head strap battery—using just a single USB-C cable. That means when you plug in your head strap with a 45W adapter, you're also topping up your headset battery at full speed—no extra cables or adapters needed.
This convenience is especially valuable for casual gamers, fitness users, or households with multiple players. You can take a short break and return to a freshly charged headset, keeping the flow going without long waiting times. Whether you're hopping into multiplayer matches, enjoying cinematic VR, or getting a quick workout in, DualFast ensures you're always ready to dive back in.
Lightweight by Design
Thanks to rapid recharging, KIWI design avoids using oversized batteries that add unnecessary weight and pressure. Both K4 Boost and H4 Boost are engineered to deliver reliable playtime with smaller but higher energy density power cells—ensuring long-term comfort without sacrificing runtime.
The result? A balanced VR experience that's more wearable and less tiring—20-35% lighter than competitors on the market, perfect for extended gaming, creative sessions, or exploring virtual worlds in total immersion.
Safety You Can Trust
Behind the scenes, KIWI design's engineering team has built dual redundancy into the circuit design, offering a new level of protection against overheating, overcurrent, and voltage instability. Both head straps meet multiple international safety and compliance certifications, giving users peace of mind along with power. Whether you choose the K4 Boost for its sleek form factor or the H4 Boost for its reduced facial pressure, both models deliver a safer and more comfortable VR experience powered by DualFast charging.

If you buy something via one of our links, we may earn a commission. No one is enthused to find out their car battery died. But just because you left the headlights on overnight doesn't mean it's time for a replacement. These days, it doesn't take a trained mechanic to recharge any type of battery found in an internal combustion engine vehicle. Automatic car battery chargers are widely available, easy to use, and more affordable than ever. In fact, this Husgw charger is on sale for $24 at Walmart— 82% off the original $139 price tag — and offers everything you need to not only jump start your car but restore it to its full glory. In addition to every type of 12V lead-acid battery, the Husgw T90583 is compatible with larger 24V batteries used in many heavy duty trucks and industrial vehicles. The only car batteries it won't charge are the lithium-ion variety found in battery-electric and hybrid vehicles — fortunately we have EV chargers for that. For the vast majority of batteries it will charge, the Husgw T90583 is essentially plug and play. Just connect each clamp to its corresponding terminal, select your mode, and start charging. Once it's finished the job, the charger will automatically shut off. Since it is self-regulating, you won't have to babysit your battery charger for hours on end. Modern chargers including are equipped to prevent overcharging, overheating, and short-circuits. That said, you can intuitively monitor activity such as charge status, battery life, voltage, current, and temperature on the built-in LCD display. In addition to charging batteries, the device can extend the life of older, worn-down, or slightly damaged batteries, thanks to its pulse repair function. Additionally, the charger doubles as a maintainer to keep your battery from dying in cold weather, especially if it's not driven regularly. Reviews of the car battery charger are favorable. One customer even called it an 'exceptional battery charger,' praising its 'advanced features.' 'The Husgw 12V 10A battery charger is a fantastic piece of equipment!' added that reviewer. 'From the moment I started using it, I was impressed by the intuitive color screen digital display that makes monitoring the charging process straightforward.''Stylish and sturdy,' said another shopper. 'I definitely find great attraction in this charger's exquisite design and small size.' Other customers noted its compact size and impressive performance for the price. In any case, a battery charger is a smart addition to any automotive emergency kit, and the Husgw T90583 is among the most affordable considering the extent of its capabilities. For $24, you might as well give it a shot.

Flip foldables are running into design wall, and you're just going to accept it
When foldable phones first arrived on the scene, it was a durability disaster at Samsung. It took the company a few generations to fix the underlying hinge and display issues. And by the time the formula was perfected, every smartphone brand had already put their foldable phones on the shelf, except Apple. As the design matured and clamshell foldable phones arrived on the scene, the price came down while the hardware kept getting more refined. But soon, Samsung hit a design wall, a well-known trope that continues to haunt Galaxy phone buyers to date. The situation at Motorola, the only other foldable phone seller in the US market, wasn't too different. Recommended Videos Just a day ago, purported renders of Samsung's upcoming foldable phones — the Galaxy Z Fold 7 and a cheaper FE model — were leaked. The latter looks identical to Samsung's current-gen Samsung Galaxy Z Flip 6, while the former wants to play blink-and-you-miss-me with Motorola's Razr 60 Ultra. Or it's Razr 50 series rival. Or the Razr 40 Ultra. Just take a look at the images above. The Samsung and Motorola phones look virtually identical, inside and out. The only difference? Motorola likes its branding on the rear shell, which it likes to experiment with. This year, it was Alcantara and wood. Last year, the company was experimenting with vegan leather in a variety of colors. Samsung, on the other hand, hasn't tried anything except glass and metal, with a matching tone of the metallic side frame. Your only chance of standing out? Pick one from the Samsung-exclusive colors with a black side frame (yeah, that's the only difference) that is only sold via the brand's website and colors. On the outside, each brand wants to maximize the area of the cover display, which is a meaningful endeavor. After years of attempts, both brands (and a few from China) have landed at the exact same formula. An edge-to-edge screen with floating camera lenses and an LED flash module. The similarity runs so deep that if you don't carefully look at the rounded corners and sides, you won't be able to tell a Motorola Razr apart from a Galaxy Z Flip later this year. The situation with the inner foldable display is even more difficult. But then, every slab phone is also starting to look the same, including Samsung and Motorola. Does it make sense? That's a million-dollar question, and the answer would depend just how much work you can get done solely off the cover screen. Smartphone brands keep trying to one-up each other by claiming how immersive the secondary outer display on their foldable phone is. 'Largest and smartest external display,' that's what Motorola claims on its website. In a few weeks, Samsung will be fighting for those bragging rights atop the Galaxy Z Flip 7, which takes the same design formula, offers thinner bezels, and goes for less rounded corners. Or in marketing terms, relentless innovation and pursuit of hardware excellence. Now, just how much is your life going to change if the cover display goes from a 3.4-inch OLED panel to a 4-inch OLED panel? Not much, at least for me. For navigation and reading messages? Fine. For typing on a full-sized qwerty touch keyboard, you either wish your thumbs were more dainty, or the screen were a little bigger. Either way, not what you would call an ergonomically pleasing experience. The race for practicality The biggest problem is scaling. Apps look weird, even if you can now run all of them on the landscape or square-ish cover screen. Try social media apps, especially those with vertical videos, and you will know the deal. Is there a solution to it? Not really, because consumers would prefer the biggest possible screen, even if they can't get the best out of out. It also looks a lot more polished, so it's clear every brand is chasing after that edge-to-edge look. Interestingly, the problem of scaling was solved in a more natural way, not too long ago. Oppo launched a flip phone that had a traditional candybar-style secondary display on the back. It felt natural, and so did app interactions. Huawei has done something similar on the Pura X, and so has a fellow Chinese brand on the Vivo X Flip. Honor thinks the cover display should not take precedence because it's not the primary source of user interaction, so there's a lot to experiment with the design. In all the outlier cases mentioned above, the phones offer a lot more identity and look playful. It's not going to please everyone, especially those who carry the banner of 'function over form,' and if you try to with the argument that there's a perfectly fine flexible display inside that's just a flip away, it wouldn't make sense. Call it a situation of misplaced expectations, but we are at a point of no return. Clamshell-style foldable phones are going to look mostly the same moving ahead. The saving grace? If you don't care too much about standout looks, they are getting more powerful, sturdier, and in some cases, a tad cheaper, as well.

Tesla robotaxis already probed over alleged traffic offenses
STORY: They only hit public roads on Sunday, but Tesla's robotaxis already face a probe over alleged traffic violations. A small fleet of the vehicles has started operating in Austin, Texas. They're offering rides within a limited zone inside the city. But the U.S. National Highway Traffic Safety Administration says it is seeking information on the operation. Watchdogs say they have reviewed online videos purporting to show one robotaxi speeding, and another using the wrong lane. The EV maker did not respond to a request for comment by Reuters. But boss Elon Musk has said the company will be 'super paranoid' about safety. The robotaxis are avoiding bad weather and difficult intersections, and won't carry any children. Separately Monday, Tesla was sued by the estates of three people killed in a crash involving one of the firm's Model S sedans. The suit filed in New Jersey says the deaths resulted from 'defective and unreasonably dangerous design'. It centers on Tesla's so-called 'Full Self-Driving' feature. The plaintiffs say the system gives the impression it is capable of fully autonomous driving, when it actually can't cope with many everyday situations. Tesla has said the feature is meant for 'fully attentive' drivers, who are required to keep their hands on the steering wheel. It didn't respond to a request for comment on the lawsuit.
