Think of power and accessories as the backstage crew for your daily tech performance — they’re quiet, invisible, and when they fail, the show stops. From rugged phone cases and magnetic mounts to portable solar generators and backup power stations, choosing the right gear makes life less stressful and keeps your devices humming. In this guide I’ll walk you through top brands and retailers in the US, including ESR Gear and AllPowers, plus where to shop for comparable options so you can shop smart.
These days the market is stuffed with choices: magnetic phone cases that work like Lego, AirPods chargers with snap-and-charge convenience, and portable power stations meant to keep a small household running through a storm. You’ll find premium features at mainstream retailers and niche innovations from specialty brands. My goal is to cut through the noise, show practical comparisons, and help you match tech to real-life needs — not just specs on paper.
ESR Gear has built a reputation for cases and accessories that blend protection with clever extras. If you like slim profiles that don’t sacrifice function, their MagSafe-like Halolock line and snap-and-charge bundles are worth a look. These products cater to people who want phone protection, wallet convenience, and easy wireless charging without juggling multiple add-ons.
ESR’s clear and hybrid cases often include built-in stands, card pockets, or privacy elements. They’re practical for commuters and parents who want protection without a bulky feel. A case that doubles as a stand or wallet reduces the number of accessories you carry — think fewer things in your pockets and more simplicity in your bag.
Beyond cases, ESR offers screen protectors, wallet stands with tracking features, and snap-and-charge solutions for earbuds. These are the small conveniences you don’t realize you need until they save you time: instant wireless charging, more secure card storage, and screen protectors that make your phone feel new again.
AllPowers is known for making accessible portable power stations and solar generator kits that appeal to campers, van-lifers, and homeowners seeking emergency backup. Instead of obsessing over raw numbers, focus on what you want to power and for how long. That’s where AllPowers and similar brands make sense — they package battery packs with solar panels and charge controllers so you can go off-grid or weather a blackout.
Portable power stations keep essentials running: a smartphone for many recharges, a laptop for work, lights and a small refrigerator or a medical device for a set number of hours. For weekend campers, they’ll power a mini-fridge and coffee maker for a morning; for emergency preparedness, they’ll keep communication lines alive and power small medical or home devices overnight.
If you plan to camp off-grid for days or lessen your reliance on the grid during outages, a small solar panel paired with a portable station can extend runtime significantly. It’s the difference between a single-night backup and multiple days of steady, reliable power when the sun is cooperating.
Shopping for power and electronics in the US means balancing price, selection, and service. Here are reliable places to start your hunt, depending on what you value most: speed, variety, or expert advice.
Amazon is the quick-and-easy option for a massive selection of cases, chargers, and power stations. You’ll find name brands alongside newcomers, with tons of customer reviews to help with decisions. It’s a good place to compare model features and read real-life user feedback before you buy.
Prefer to touch and test? Best Buy lets you see many accessories and larger power stations in person. Staff often know which models are best for typical home uses and can suggest compatible accessories like surge protectors or extension cables. If you want hands-on confidence, this is the spot.
Walmart carries a broad mix of budget-friendly electronics and house-brand accessories, plus some name-brand chargers and portable batteries. If you’re price-conscious and need quick local pickup, it’s useful. For basic cases and entry-level power stations, Walmart often offers a solid bang for the buck.
Home Depot and Lowe’s are great for heavier-duty power needs like larger inverter systems, whole-home surge protection, and solar accessories. If your goal is backup power for household appliances or you’re integrating a generator with home electrical work, these stores pair products with the right hardware and installation accessories.
For people who live outdoors — hikers, campers, van-dwellers — REI and other outdoor outlets stock gear tailored to portability and durability. They often carry high-quality solar panels, rugged power stations, and lightweight chargers designed to survive a few bumps along the trail.
Don’t get trapped in a numbers race. Start by listing what you want to power and for how long. That practical checklist will tell you whether you need a small unit for phones and lights, a mid-size model for a laptop and mini-fridge, or a large kit for multiple appliances.
Think in terms of hours you need to run a device, not just the unit’s label. For example, if you want to keep a laptop running for an afternoon and charge phones overnight during a power outage, a mid-range unit will usually do the trick. If you need to run a refrigerator during an extended blackout, aim higher or consider adding a solar panel to top off the charge during daylight.
Look for multiple AC outlets, USB-A and USB-C ports, and car-style outlets if you plan to use the station on the road. Some units include fast-charging ports for phones or built-in LED lights. Convenience features like an easy-to-read display and simple controls make daily use much more pleasant.
Phone protection isn’t one-size-fits-all. If you drop your phone at the campsite or juggle kids and groceries, invest in a hybrid case with reinforced corners. If you want a clean-looking phone with added functionality, consider clear Halolock-style cases and wallet-stand combos that reduce the number of things you carry.
Want the convenience of magnet-backed cases and card pockets? They’re great — but check for built-in features like RFID-blocking if you’re worried about card security, and make sure the magnet system is strong enough for everyday use without interfering with wireless charging or credit card chips.
Quality tempered-glass protectors shield your screen from drops and scratches without affecting touch sensitivity. Look for packages that include alignment tools; they make installation painless and reduce bubbles that can ruin the experience.
Brands vary by focus. ESR is all about accessories that enhance phone usability, AllPowers focuses on accessible portable power, Anker is known for reliable charging tech, and Goal Zero leans toward rugged, adventure-ready power systems. Your choice depends on whether you prioritize price, portability, durability, or innovation.
Sometimes paying a little more up front gets you a product that lasts longer and performs better in the long run. If you rely on a power station for emergency backup, reliability is worth the investment. For phone cases, balance cost against the level of daily protection you need.
Check warranty length and what it covers. A three-year warranty on a power station gives peace of mind during heavy use, while a limited warranty on a case might not be as crucial. Brands that stand behind their products are often easier to work with when something goes wrong.
Little habits add up. Store batteries in a cool, dry place, avoid fully draining a portable power station regularly, and keep software updated on devices to avoid unnecessary battery drain. For phone cases and protectors, clean surfaces gently and avoid harsh chemicals that can degrade materials.
It’s better to keep portable batteries between about one-quarter and three-quarters charged for long-term health rather than repeatedly charging from empty to full. If you use solar charging, try to avoid overexposing panels to heat while charging to preserve efficiency.
Wipe connectors gently, inspect ports for debris, and replace cables when they show fraying. A good cable is cheap insurance against damage to expensive devices.
Power gear is safe when used correctly, but it’s not foolproof. Avoid cheap knockoffs that cut corners on protective circuitry, don’t expose power stations to standing water or extreme heat, and use the right type of extension cords and surge protection for heavier loads.
Never modify internal batteries or try to open sealed power stations unless you’re trained. Don’t overload a unit by trying to run multiple large appliances at once — that’s a quick way to trip the unit and potentially damage your devices.
Before you click “buy,” run through this quick checklist: Do you know what you need to power and for how long? Have you confirmed port types and counts? Is the retailer reputable and does the brand offer a reasonable warranty? Will the unit be easy to carry or install where you plan to use it? If you can answer these confidently, you’re ready to shop.
From ESR Gear thoughtfully designed cases and accessories to AllPowers practical portable power solutions, there’s no shortage of smart options in the US marketplace. Whether you shop at online marketplaces, big-box stores like Walmart and Best Buy, or specialty retailers such as REI and Home Depot, the key is to match the product to your real needs. Focus on runtime instead of raw labels, prioritize convenience and build quality, and shop from retailers and brands you trust. Do that, and your tech will work for you — not the other way around.
