A 20,000 mAh power bank can typically charge most modern smartphones three to four times before it runs out of power itself. This matters because it means you could go on a full day of travel, camping, or errands without worrying about your phone battery dying and leaving you unreachable. Worth knowing: the actual number of charges varies depending on your phone model and battery size, so check your phone's specs if you want a precise estimate.
Una, a Scottish company, has designed a GPS watch where you can replace broken parts yourself instead of throwing the whole thing away—something most smartwatch makers don't allow. For people who've watched their expensive gadgets end up in landfills, this matters because a repairable watch could save money and reduce waste over time. Worth knowing: when your current smartwatch battery dies or a band breaks, check whether the manufacturer offers replacement parts before you buy, since this approach is still rare.
# EV Charging Options Explained
If you mostly drive short distances around town, a standard Level 1 charger (the kind that plugs into a regular household outlet) can be perfectly adequate for your needs. Level 1 is slower than fancier options, but for someone who charges overnight and drives locally, the convenience and cost savings of using what you already have at home often outweigh the speed advantages of installing expensive equipment. Worth knowing: if you regularly take longer road trips or have a short commute but drive multiple times daily, investing in a faster Level 2 charger at home would give you more flexibility and peace of mind.
3D printers today are easier to use and more reliable than they were a decade ago, though they're still mainly used by hobbyists and small businesses rather than regular households. If you enjoy making things—whether it's spare parts, garden fixtures, or gifts—a 3D printer could be a satisfying hobby, but they do require patience to learn and ongoing maintenance. Worth knowing: before spending significant money, you might visit a local community center or "makerspace" that lets you try one for free or cheaply to see if it's really for you.
Foldable phones have extra vulnerable spots—especially that folding hinge—which makes them more prone to damage from dust and everyday wear than traditional flat phones. If you're considering buying one, a protective case isn't optional; it's really part of the deal if you want your phone to last. Worth knowing: when shopping for a foldable phone, budget for a quality case at the same time, and ask the seller which cases offer the best hinge protection.
A full surround sound system gives you that cinema-like experience with speakers placed around your room, while a soundbar is a single device that sits under your TV and does the job more simply. If you watch a lot of movies and have the space and budget for it, a surround system really does make action scenes and dramatic moments feel more engaging—but a good soundbar handles everyday TV watching just fine and costs much less. Worth knowing: try visiting a friend's house or a shop that has both set up, so you can hear the difference yourself before spending significant money.
Google Maps works fine in your car, but Apple's system doesn't let it become your main navigation app the way Apple Maps can. If you prefer Google Maps for its better traffic updates or familiar layout, you'll need to use a workaround rather than having it start automatically. You can launch Google Maps manually each time you drive, or ask your phone's voice assistant (Siri) to open it for you—which is almost as convenient once you get the habit.
# When to Use a Bike Computer Instead of Your Phone
A dedicated bike computer is worth considering when your smartphone struggles with battery drain, gets hard to read in bright sunlight, or keeps losing its signal on remote rides. For many casual cyclists, a phone works fine, but serious riders or those tackling rough terrain often find a bike computer more reliable and longer-lasting. Worth knowing: if you're planning rides longer than a couple of hours, frequently bike in bad weather, or find yourself constantly stopping to recharge your phone, a bike computer designed for outdoor use might be a worthwhile investment.
Sennheiser's new Momentum 5 headphones deliver excellent sound quality and can run for over 60 hours on a single charge, making them among the longest-lasting wireless headphones available today. For people who travel, listen to music regularly, or simply hate charging devices frequently, that battery life means you could go weeks without plugging them in. You can check if these headphones work with your phone or tablet before buying, since they connect via standard Bluetooth like most wireless headphones do.
Google is quietly testing a new way for people in India to shop at Flipkart (owned by Walmart) using its Gemini AI assistant—you could soon ask an AI chatbot to find and buy things for you instead of browsing yourself. For older shoppers who find traditional apps confusing, having an AI do the searching and comparing could make online shopping feel less overwhelming and faster. Worth knowing: if you use Google services and live in India, you might see this feature appear in your account later this month, though it's starting with a small group of customers first.
# Power Banks for Laptops: What You Really Need to Know
Most people think a power bank just needs to be big enough, but it also has to deliver power fast enough—otherwise your laptop battery keeps draining even while it's plugged in. For anyone who travels or works away from outlets, choosing the right one means the difference between a helpful backup and an expensive paperweight. Worth knowing: check that a power bank's wattage (often printed as "watts" or "W") matches your laptop's charger—if it's too weak, it won't actually charge your device.
# Phone Steam Damage: What You Need to Know
Even phones labeled "waterproof" can be damaged by hot steam from showers because water vapor can seep into tiny gaps that ordinary water droplets cannot penetrate. This matters because many of us assume our expensive phones are protected in any wet situation, when really steam poses a different—and sneakier—kind of threat. Worth knowing: if you do accidentally expose your phone to steam, power it off right away and let it dry completely in a warm room for at least 24 hours before using it again.
