Power Bank Feature Creep is Out of Control

The humble power bank has transformed from a simple pocket-sized battery into a feature-laden gadget that now sometimes includes screensavers, Bluetooth connectivity and built-in Wi-Fi hotspots. The Verge's Thomas Ricker highlighted the $270 EcoFlow Rapid Pro X Power Bank 27k at CES 2026 as a prime offender -- a device he declared "too expensive, too big, too slow, and too heavy." Its giant display takes 30 seconds to wake from sleep, plays swirly graphics and blinking eyeballs, and requires a screensaver while slowly draining the battery it's meant to preserve. The feature creep is industry-wide. Anker no longer lists a display-less model in its 20,000mAh range, and both companies sell proprietary desk chargers. Basic alternatives exist -- Anker's PowerCore 10k runs $26 -- but they're becoming harder to find.

Are Hybrid Cars Helping America Transition to Electric Vehicles?

4 janvier 2026 à 23:49
America's electric car subsidies expired at the end of September, notes Bloomberg. Yet in those last three months, "while fully electric cars and trucks made up 10% of all auto sales in the US... another 15% of transactions were for hybrid vehicles." The EV market is slowing in the U.S., but analysts expect hybrid sales to continue accelerating. CarGurus Inc., a digital listings platform that covers most of the US auto market, predicts nearly one in six new cars next year will be a hybrid, as automakers green-light more and better machines with the technology. And though these cars and trucks will still burn gas, they will quietly move the needle on both transportation emissions and the transition to fully electric cars and trucks... CarGurus calls hybrids the success story of 2025. Indeed, the fastest-selling car in the country this year has been the Hyundai Palisade Hybrid; it sat on lots for fewer than 14 days on average... While carmakers have struggled to turn a profit on fully electric vehicles, analysts say their investments in batteries and electric motors are helping them sell more and better hybrid machines. It's also increasingly difficult to discern a hybrid from a solely gas-powered model, said Scott Hardman, assistant director of the Electric Vehicle Research Center at the University of California at Davis. Carmakers today often don't even label a hybrid as such. Consider Toyota's RAV4, one of the best-selling vehicles in America. The 2026 version of the SUV comes in six different variants, all of which include an electric motor and a gas tank. "A hybrid is just a regular car now," Hardman said. "You can buy one by accident...." While not as clean as an electric vehicle, hybrids offer sneaky carbon cuts as well. Americans, on average, drive about 38 miles a day, which requires about one gallon of gas in most basic hybrids. Contemporary plug-in hybrids, which can run on all-battery power, can cover almost that entire range without the gas engine kicking in. And a small crowd of cars will do even better, stretching their batteries well over 40 miles per charge. All told, hybridization can reduce the carbon dioxide emissions of a vehicle by roughly 20% to 30%, according to the International Council on Clean Transportation. Some interesting statistics from the article: By 2030 Ford expects fully or partially electrified vehicles will represent half its global sales. Toyota has already reached 50% ("in part thanks to all those hybrid RAV4s"). Honda is "basing its entire business on hybrids until at least 2030." Around one-third of America's hybrid drivers "transition to a fully electric vehicle when they next switch cars." In September 57% of America's car shoppers "were considering a fully electric auto, according to JD Power. However, among hybrid households, that share was almost 70%."

The US Effort to Break China's Rare-Earth Monopoly

4 janvier 2026 à 12:34
The New York Times checks in on U.S. university researchers and start-ups trying to create domestic rare-earth processing facility: There is too little money to be made in rare earths for the elements to be of much interest to mining giants, so the challenge of reestablishing a domestic industry has fallen to small companies like Phoenix Tailings, a Boston-area startup that runs the metal-making plant in Exeter, New Hampshire. A handful of other companies in the United States are processing rare earths in small quantities, including MP Materials, which owns a mine in Mountain Pass, California, and recently began producing rare-earth metal in Fort Worth, Texas. Similar efforts are underway in Europe and Asia. "It's small volumes of low-value materials that are very expensive to process," said Elsa Olivetti, a materials science and engineering professor at the Massachusetts Institute of Technology. "Meaning it's hard to make money." Phoenix Tailings' New Hampshire operation is about 2 months old, housed in a converted medical device plant. The company buys metric-ton bags of powder — a mixture of neodymium and praseodymium bound with oxygen — from mining and refining companies in the United States, South America and Australia. It funnels that flour-like material into a drying oven and eventually into furnaces that heat it to the temperature of volcanic lava. This circuit takes up less than 15,000 square feet and is designed to generate no emissions other than those associated with the electricity Phoenix Tailings uses. The closed-loop design distinguishes this process from the more energy-intensive techniques used in China, where workers scoop up molten metal with ladles. That approach releases perfluorocarbons, potent greenhouse gases that do not break down easily. In late 2024 the company was three weeks from bankruptcy — but it's recently been valued at $189 million.

New Tesla Video Shows Tesla Semi Electric Truck Charging at 1.2 MW

4 janvier 2026 à 05:34
An anonymous reader shared this report from Electrek: Tesla has released a new video showing a Tesla Semi truck charging at a massive 1.2 megawatts (MW), finally giving us a clear look at the charging speeds that will enable long-haul electric trucking...> Tesla claimed the Semi would be able to charge 70% of its range in 30 minutes. For a truck with a 500-mile range and an estimated battery pack of around 800-900 kWh, that requires an incredibly high power output, well beyond the 250 kW or even 350 kW we see on passenger EVs in North America. Today, the official Tesla Semi account on X released a video showing exactly that. In the video, Tesla engineers are seen monitoring a charging session where the power output climbs to a peak of 1.2 MW (1,206 kW). This is consistent with the capabilities Tesla announced for its new V4 Cabinet architecture earlier this year. The V4 cabinets are designed to support 400V-1000V vehicle architectures and can deliver up to 500 kW for cars (like the Cybertruck) and up to 1.2 MW for the Semi. There is some information missing from the video. For example, we don't see the state-of-charge of the truck, so we don't at what battery percentage Tesla Semi can achieve and maintain this charge rate. Peak speed is one thing, but sustaining that power without overheating the pack or the cable is the real challenge. The liquid-cooled charging cable and the immersion-cooled connector (part of the Megawatt Charging System or a high-power proprietary Tesla solution, though Tesla has been leaning toward MCS compatibility) seem to be doing their job.... This comes just as Tesla is gearing up for volume production of the Semi at its new factory expansion near Gigafactory Nevada. The automaker is targeting a start of production in the first half of 2026 and a ramp up to volume production in the second half.
