Ultimate Guide to Input Device Accessories: Cases, Screen Protectors, and Power Solutions for Your Gear

Why input device accessories deserve your attention

Think of input device accessories as the seatbelts and helmets for your tech — small additions that save you big headaches down the road. Whether you’re protecting AirPods, a tablet screen, or the camera lens on a flagship phone, the right accessories extend device life, preserve resale value, and improve everyday usability. Plus, they make your gear feel personalized and ready for real life: drops, spills, and the daily grind.

Brands and sellers to know in the US market

If you’re shopping for input device accessories, a few names keep popping up for quality, variety, and value. ESR Gear is known for protective cases and paper-feel magnetic screen protectors tailored to modern tablets and earbuds. AllPowers focuses on portable power solutions like expansion batteries that support off-grid use and long sessions away from a wall outlet. Beyond those brands, major US retailers such as Amazon, Best Buy, Newegg, B&H Photo, Micro Center, and Walmart stock a wide range of cases, protectors, and power packs, so you can compare price, warranty, and shipping options easily.

ESR Gear: cases, screen protectors, and camera protection

ESR Gear has built a reputation on practical, stylish accessories: think Cyber Tough cases for AirPods with Halolock magnetic features, paper-feel magnetic screen protectors for iPad models, and camera lens protectors designed for flagship phones. If you like tactile feedback when sketching or typing on a tablet, ESR’s paper-feel protectors are a solid bet. And for people who carry earbuds in pockets and backpacks, tough hybrid cases with reinforced edges and magnetic locking add a layer of confidence.

AllPowers: power when you need it most

When the stream is long or the campsite is remote, portable power becomes a must. AllPowers offers expansion batteries like the B1000 — a high-capacity unit (listed at 1152 Wh) that’s useful for powering laptops, mini-fridges, and more during long outages or mobile work sessions. Refurbished options can save you money while delivering substantial runtime for gear that sips and gulps power in different ways.

Where US shoppers commonly buy accessories

Retailers matter because return flexibility, shipping speed, and customer reviews differ. Amazon excels in selection and fast shipping, Best Buy is convenient for trying products in-store, Newegg caters to enthusiast buyers, B&H Photo is trusted for photo and video accessories, Micro Center is great for hands-on testing, and Walmart offers value-focused options. Use multiple sources to compare prices and look for bundles like case + screen protector combos to maximize savings.

Must-have accessory types and how they help

Accessories fall into a few practical categories: protective cases, screen protectors, camera lens guards, charging and power solutions, and cable or desk accessories that improve how you interact with your devices. Each type answers a common problem: accidental drops, scratches, battery anxiety, and messy setups. Here’s how to prioritize.

Protective cases for earbuds and phones

AirPods and other earbuds live a risky life — tossed in pockets with keys or dropped on pavement. A Cyber Tough case or Orbit Hybrid case with Halolock magnets provides drop protection, dust resistance, and an easy way to carry earbuds without adding bulk. Look for cases that add less than 0.25 inches in thickness and weigh under 1 ounce if you want a slim profile that won’t disrupt wireless charging or pocket comfort.

Paper-feel magnetic screen protectors for tablets

If you use an iPad for drawing, note-taking, or long reading sessions, a paper-feel magnetic screen protector changes the experience. These protectors reduce glare and add fine-grain texture so the Apple Pencil or stylus feels more like a real pen on paper. They typically attach with magnets for snap-on installation and are available for models like the iPad Pro 11-inch and iPad Air 10.9-inch. Expect negligible added thickness, but big gains in control and reduced fingerprint smudging.

Camera lens protectors and stylish protection

Phone camera arrays have become delicate, multi-lens systems that cost hundreds to replace. Lens guards — like armorite camera lens protectors — add a slim, clear layer over each glass element without affecting photo quality. Some versions come with decorative finishes, such as glitter silver, giving protection with a dash of personality. These are usually measured in inches for diameter and add only a fraction of an ounce in weight.

Portable power: expansion batteries for long use

For anyone who relies on devices away from outlets, high-capacity expansion batteries change the game. A unit like the B1000 is built to power laptops, multiple phones, and even small appliances during extended use. Refurbished units can offer big savings, but make sure the seller includes health checks and clear warranty terms so you know what to expect in terms of battery cycles and peak output.

How to choose the right product for your needs

Choosing accessories is part science, part lifestyle fit. Start by asking: how do I use this device daily, and what risks does it face? If you toss a tablet into a backpack with a laptop, heavy-duty corner protection and a textured case are priorities. For a home-only tablet used for drawing, a paper-feel protector and a thin folio could be the best match. Prioritize compatibility by model name and screen size — for tablets, that means exact inch count like 11 inches or 10.9 inches — and check whether a case supports magnetic accessories like styluses or keyboards.

Fit, function, and feel

A snug fit matters. A case that’s too loose lets dirt migrate and components rattle; one that’s too tight can be hard to remove or cause long-term stress on ports. For screen protectors, check edge-to-edge coverage claims and whether the protector interferes with face unlock, fingerprints, or stylus responsiveness. For power solutions, look at maximum output in watts and the number of outlets or ports you’ll need to run devices simultaneously.

Refurbished vs. new items

Buying refurbished can be a smart way to stretch your budget, especially for power equipment that’s been professionally tested and restored. If you go refurbished, verify the seller’s refurbishment standards, battery health tests for packs like the B1000, and any included limited warranty. Refurbished cases and protectors are less common because those items have low failure rates, but when available, they can be nearly as good as new at a lower price.

Installation and maintenance tips

Accessories protect devices only if they’re installed and cared for correctly. A rushed screen protector install can trap dust and ruin clarity, while a poorly seated lens protector can produce glare. Here are practical tips to get it right the first time and maintain your kit over months and years.

Applying screen protectors like a pro

Work in a dust-free area, use the included cleaning cloth and dust-removal sticker, and align the edges before pressing down. If a bubble appears, use a credit card wrapped in a microfiber cloth to smooth it toward the nearest edge. Magnetic paper-feel protectors simplify alignment thanks to the magnetic frame that snaps into place, reducing installation headaches.

Cleaning cases and lens protectors

Use a soft, lint-free microfiber cloth and a 70-percent isopropyl wipe for stubborn smudges. Avoid abrasive cleaners that may wear off decorative finishes like glitter or metallic coatings. For lens protectors, breathe gently and wipe in a circular motion from the center outward to avoid scratching the delicate glass or coating.

Where to compare prices and features

Shopping wisely means comparison. Online marketplaces and retailer sites list user reviews, specs, and often price history. Comparison platforms aggregate deals across sellers so you can spot discounts quickly. When comparing, don’t just chase the lowest price — factor in shipping speed, warranty length, and return flexibility. For tech accessories, a small premium for a trusted seller is often worth the extra peace of mind.

Saving tips and timing your purchases

When should you buy? Look for deals around major shopping events such as Black Friday, back-to-school season, and big product launches (new phones and tablets often spur accessory sales). Consider buying kit bundles — case plus screen protector — which frequently deliver better overall value than purchasing items separately. Refurbished power packs or clearance items can also be excellent buys if you confirm battery health and seller guarantees.

Compatibility cheat sheet for common devices

Here’s a quick compatibility guide to keep in your head while browsing: choose AirPods cases labeled for your specific generation (AirPods 4 vs. AirPods Pro), pick screen protectors by exact tablet model and inch size (iPad Pro 11-inch vs. iPad Air 10.9-inch), and match camera lens guards to your phone model (e.g., Galaxy S25 Ultra). For power accessories, match the watt output to your device needs: a laptop typically needs 45–90 watts to charge while running, whereas phones often charge at 18–30 watts depending on fast-charging capabilities.

Final buying checklist

Before you click buy, run through a quick checklist: confirm device compatibility by exact model and inch size, read multiple user reviews for real-world durability feedback, check return and warranty terms, decide between new and refurbished based on savings and seller trust, and compare prices across at least three retailers. This little routine helps you avoid returns and buyer’s remorse.

Conclusion

Input device accessories are more than cosmetic extras — they’re protection, power, and comfort wrapped into small, affordable upgrades. Brands like ESR Gear and AllPowers offer focused solutions for cases, screen protectors, camera guards, and high-capacity backup power. Pair those products with smart shopping at major US retailers and comparison platforms, and you can outfit your devices for daily life without breaking the bank. Ready to level up your setup? Start with the one accessory that solves your biggest daily pain point and build from there — it’s the easiest path to a smarter, less stressful tech life.
