This 42,800mAh Solar Power Bank Is Down to Freebie Territory as Amazon Clears Out Its Best-Seller Shelves

Gizmodo28-07-2025
Running out of phone power when you are off the grid is a fast way to end a good day early. Maps stop loading, group texts die, and the flashlight you need after sunset fades to black. The 42,800mAh Portable Charger gives you a big reserve tank you can toss in a backpack, glove box, or emergency drawer at home. That huge capacity (manufacturer rated at 42,800mAh) means several full refills for most phones, plus top ups for earbuds, fitness bands, and a tablet when the family all plugs in at once.
Head over to Amazon to get the 42800mAh Portable Charger for just $25, down from its usual price of $40. That's a discount of $15 and 36% off.

You get multiple charging ports so more than one device can sip power at the same time. Plug in a phone on the fast USB-C port, hand a cable to a friend for their older USB-A device, and still have room to top off a Bluetooth speaker. The bank pushes a strong initial charge that jumps a dying battery into the safe zone in a few minutes, handy when you only have a pit stop before hiking deeper into the trail.
A solar panel spans the top surface. Solar recharging is slower than a wall plug, so think of it as a bonus trickle that stretches the battery during long camping weekends or multi-day festivals. Clip the charger to a pack with the panel facing out and let sunlight give back a little juice while you walk. Even a slow top up can buy another round of photos at sunset.
The rugged shell is built for outdoor use. Textured sides help you keep a grip with sunscreen hands, and tight port covers help block dust and light splashes. Twin LED lamps on one edge serve as an emergency flashlight; hold the button and you get a bright beam for tent zippers, dropped keys, or a fuse box in a blackout. Some versions include strobe and SOS modes, useful roadside.
Topping the battery itself is simple. Use the included cable and plug into a wall adapter the night before a trip, then lean on solar to extend runtime once you are out. Rotate the charger among family members and you will quickly wonder how camping worked without it.
This 42800mAh Portable Charger is still available for $25 at Amazon, a welcome cut from the regular $40 price. So if you're thinking it might be time to get one, you should pounce while you still can.

Your Kid's Riding An E-Bike Or E-Scooter? What Parents Should Know

Look in your rearview mirror these days on suburban roads. You may do a double take. Is that a child zipping by on a motorcycle with no helmet? You look closely. It's not actually a motorcycle. Maybe it's an e-bike. Or an electronic dirt bike? Across the country, kids and teens are increasingly riding light electric vehicles, or LEVs. LEVs are an emerging category that includes e-bikes, electric scooters, mopeds and electric dirt bikes. These battery-powered machines reach speeds of 20, 30 even >50 miles per hour. As these vehicles proliferate, so do questions about how parents should address safety and how they should be regulated. A Guide to Light Electric Vehicles: What They Are and Who Can Legally Ride Them LEV is an umbrella term for a broad range of battery-powered vehicles. All are lighter and less powerful than traditional gas-powered motorcycles. But in some cases, not by much. E-scooters are increasingly popular with kids and teens. These slim, stand-up vehicles accelerate rapidly and are simple enough for young children to operate. Many brands of e-scooters exist on the market and are available on Amazon. Popular brands include Segway, GoTrax, NIU, Emove and others. While top speeds a few years ago were limited to 10–15 mph, today many models can easily reach 20 mph or more. Most states set a minimum age for e-scooter use between 12 and 16. California, for example, requires riders to be at least 16. Some states have no minimum. Most do not require a driver's license or vehicle registration for e-scooters used on public roads, though some cities (like New York) require registration for faster models. Helmet use is typically required for riders under 18. E-bikes are bicycles equipped with electric motors that assist with pedaling. They make riding easier over long distances and hills. E-bikes come in three federally defined classes, capped at 750 watts of motor output: Brands such as Aventon, Specialized, Trek and Rad Power are stocked in bike shops while some e-bikes like Schwinn and others are available on Amazon or Walmart. Classes 1 and 2 e-bikes typically have no age or license requirements. Class 3 bikes often require riders to be at least 14–16 years old, depending on the state. Helmets are generally required for riders under 16 and for all Class 3 bikes. Bike path access is usually limited to Class 1 and 2 while Class 3 e-bikes are often restricted to roads and bike lanes. Registration is rarely required for Class 1 or 2, but some states mandate it for Class 3. Electric dirt bikes are high-powered, off-road vehicles with top speeds of 40–50 mph. They feature rugged tires, high suspension and motors that commonly exceed 2,000 watts, placing them squarely in motorcycle territory in terms of performance and risk. A recognizable example of an electronic dirt bike is the Sur-ron Light Bee X which can reach a speed of 46-60 mph and has a list price of $4,400. Most states do not allow electric dirt bikes on public roads, sidewalks, or bike paths. They are typically restricted to private property or designated off-highway vehicle (OHV) trails. In states like Massachusetts and Pennsylvania, they are explicitly barred from public land use. Electric dirt bikes generally cannot be registered for road use. Insurance is typically unavailable. While there are no age restrictions in most jurisdictions, enforcement varies—and police may issue warnings, fines, or impound the vehicle if a minor is caught riding on public streets or trails. Mopeds straddle the line between e-bikes and motorcycles. They often resemble standard e-bikes but are heavier, more powerful, and throttle-based. Many mopeds reach speeds of 50+ mph or more and may include pedals, though propulsion comes primarily from the electric motor. Mopeds are more squarely in the light motorcycle category. Most states require moped riders to be at least 15 or 16 and to hold a learner's permit or special license. Registration and insurance are required in most states. Helmets are mandatory for all riders, regardless of age. Mopeds are typically allowed on public roads but not on sidewalks or bike paths. Yet there is a kid version of a moped called the Razor Pocket Mod – a retro-style electric scooter designed for kids and teens with a top speed of up to 15 mph. It costs $348 at Walmart. According to the manufacturer, it is best suited for ages 13 and up and is meant to be used on private roads or sidewalks. A smaller version The Pocket Mod Petite is marketed to children 7+ and reaches a max speed of 8 mph. The Data: What We Know About The Safety of E-bikes And Other LEVs Several studies have documented a steep rise in injuries tied to LEVs in children and teens. Below are a few notable ones: What Parents Can Do to Reduce the Risk Of E-bikes And Other LEVs With injury rates rising and laws struggling to keep pace, parents play a critical role in protecting their kids. Before purchasing or allowing a child to ride an LEV, review the manufacturer's specifications on speed, power and age recommendations. True e-bikes should not exceed 750 watts or 28 mph under federal guidelines. Scooters for kids should generally be capped around 15 mph. Regulations vary widely by city and state. Some areas allow LEVs on sidewalks. Others ban them entirely. Check whether your locality requires helmets, registration, insurance or licenses. Wearing a helmet reduces the risk of serious head injury by at least 53% and the risk of fatal injury by 34%, according to the American College of Surgeons. For high-speed rides, consider full-face helmets and protective gear like elbow pads, knee pads, and gloves. LEVs are easy to ride, but that doesn't make them safe. Parents should set clear rules, limit riding to safe environments and supervise younger children closely. Riding two to a scooter or e-bike is both unsafe and illegal in many places. Many injuries occur when multiple children share one device simultaneously. Ultimately electric scooters, e-bikes and other LEVs aren't just the latest toys. They are fast, powerful machines that can cause serious harm and even death if used unsafely. Emergency departments nationwide are seeing more head trauma, fractures and life-altering injuries tied to these rides. The legal landscape remains confusing and inconsistent. Until city, state and federal regulations catch up, it's up to parents to understand the risks of LEVs like e-bikes and scooters, know the rules and guide their children safely. An informed adult and a well-fitted helmet may be the best protection a child can have.

Could Genie 3 From Google DeepMind Resurrect VR For Education?

Virtual Reality has long promised to enhance education. It offered visions of students exploring Ancient Rome in 3D, dissecting virtual frogs without the mess, or walking through the human bloodstream at a microscopic scale. Yet those visions rarely made it into everyday classrooms. Why? Creating accurate and robust VR learning experiences just isn't realistic for the average educator. Teachers already juggle lesson planning, grading and classroom management. Expecting them to master 3D modeling software, animation pipelines and game engine scripting was never realistic. Even companies that specialize in educational VR often struggle with the cost and complexity of developing interactive content that is both engaging and accurate. Could all of that be about to change? Google DeepMind just announced Genie 3, and it's quite frankly astonishing. What is Genie 3? Genie 3 generates interactive 3D environments in real time, from simple text prompts. Type "a rainforest ecosystem" or "the surface of Mars in 2050" and Genie responds by building immersive, explorable worlds in seconds. These aren't pre-rendered videos. They're dynamic, reactive spaces that users can navigate and interact with at 24 frames per second. This capability isn't entirely new. Previous iterations, like Genie 1 and Genie 2, and other video-generation models such as Veo 2, began to explore what was possible. But they lacked the real-time interactivity and environmental consistency needed for serious educational use. Genie 3 seems to bridge that gap. It allows learners to explore a world, revisit locations, and witness events unfold with continuity. For educators, this could be the tipping point. Building a virtual field trip used to require teams of developers, designers and researchers. Genie 3 collapses that workflow into a few lines of text. A teacher preparing a lesson on climate zones might input: "A desert landscape transitions into a temperate forest, then a polar ice cap." Genie 3 renders it on the spot, complete with weather patterns and animal behavior. This ease of creation addresses the most critical bottleneck: time. Genie 3 may make certain types of immersive teaching possible for the first time. A history teacher could summon ancient Babylon and guide students through its streets. A physics teacher could create zero-gravity environments to demonstrate Newton's laws. Genie 3 also allows "promptable world events." This means educators can inject interactivity into the scene. Want to demonstrate the impact of deforestation? Trigger a scenario where logging machines clear a portion of the forest. Students can observe changes in weather, animal migration, and biodiversity. These are not scripted animations. They are emergent responses, built on the fly based on user inputs. This level of control and flexibility could move Genie 3 beyond novelty. Could it become a tool for critical thinking and exploration? Students not just observing, but experimenting. Genie 3 Limitations Despite the excitement, limitations remain. Genie 3 can't yet model real-world locations with geographic precision. It doesn't simulate complex interactions between multiple agents, meaning multiplayer educational scenarios are still out of reach. And while the system supports a few minutes of consistent interaction, it isn't designed for extended sessions. But these are technical constraints, not conceptual ones. The trajectory is clear. This raises new questions. What happens when content creation becomes so easy that anyone can build a virtual experience? Who ensures accuracy? Who reviews for bias? In classrooms, these questions matter deeply. A world model that misrepresents historical events or scientific principles could mislead students at scale. DeepMind acknowledges this. Genie 3 is being released gradually, with oversight from its Responsible Development & Innovation Team. Only selected researchers and creators have access for now. That approach slows widespread adoption but gives space to refine safeguards. Even in this early phase, it's clear that Genie 3 could redefine what is possible in educational content creation. We could be entering a time when educators no longer have to choose between depth and interactivity. No longer spend months developing a single VR lesson. If Genie 3 delivers on its promise, or indeed Genie 4 or 5, immersive learning will move from the margins to the mainstream. The real power of Genie 3 isn't in its graphics or speed. It lies in who gets to use it. When a teacher or a student with no technical background can build a realistic simulation in seconds, the conversation around educational VR changes. From "why don't more schools use this?" to "how will we use this next?" VR in education hasn't failed. It's been waiting. Waiting for a tool that matches the ambitions of the classroom. Genie 3 might just be that tool.
