Laptop Accessories: The Must-Haves Worth Buying in 2026

Updated September 21, 2026 · By James Foleck · Originally published April 8, 2021

A laptop is built as a compromise: a keyboard fused to a screen, a handful of ports, a battery sized to keep the weight down. The right laptop accessories undo the compromises that affect how you work. The wrong ones add weight to your bag and do very little.

Good laptop accessories also do something less obvious: they protect the laptop itself. Scuffed lids, cracked displays and batteries worn down by heat are the things that move a used laptop’s value when you eventually sell or trade it in. That’s why this guide points out the resale angle wherever it applies.

Protective cases and sleeves: the accessory that pays you back

Cosmetic condition is one of the first things a buyer checks on a used laptop, and dents, scratches and screen damage all show up in the offer. Our breakdown of the factors that determine a laptop’s resale value goes through them in detail. Of all the laptop accessories on this list, a case is the cheapest protection against most of them.

Sleeve, hard shell, or bag?

• Padded sleeve. Slides into any backpack or tote and absorbs bumps. The best all-rounder for most people.
• Snap-on hard shell. Guards the lid and base against scratches during daily use, but adds bulk and can trap grit between the shell and the chassis. Pop it off and clean underneath now and then.
• Laptop bag or backpack with its own compartment. Adds room for a charger, mouse and cables. Look for a padded compartment that keeps the laptop from resting on the bottom of the bag.

One more caution: according to Apple, charging a device inside certain styles of cases can generate excess heat that affects battery capacity. If your laptop gets hot while it charges in a shell, take the shell off first.

Stand, keyboard, mouse and monitor: turning a laptop into a workstation

Because a laptop’s screen and keyboard are joined, there’s no position where both are right at the same time. Put the keyboard at a comfortable height and the screen is too low, so you end up looking down at it all day.

The Occupational Safety and Health Administration’s workstation guidance is specific. It recommends placing a monitor so the top of the screen is at or slightly below eye level, at a viewing distance of 20 to 40 inches, with the center of the screen 15 to 20 degrees below eye level. It also advises that when laptops are used as primary work computers for intensive keyboard work, auxiliary full-size keyboards and monitors should be provided.

Laptop stand and external keyboard

This is the cheapest way to hit those numbers. A stand raises the laptop’s own screen toward eye level, and a separate keyboard brings your hands back down to a comfortable height. The pairing folds flat, so it works in a home office and when you travel.

Mouse

A touchpad is fine for quick tasks. For long sessions, spreadsheets, design work or gaming, a mouse is more precise and easier on your wrist. A Bluetooth mouse keeps your ports free. A mouse with a USB receiver takes up a port but skips the pairing step. Gamers usually prefer a wired or dedicated low-latency wireless mouse.

External monitor

A second screen is the biggest productivity upgrade on this list if you work at a desk. Before you buy one, check which of your laptop’s ports can output video (HDMI, or a USB-C port with DisplayPort support) and the highest resolution and refresh rate they support. If you need a second screen on the move, our look at dual-screen laptops and what remote workers think of them covers the built-in alternative.

USB-C hubs vs. docking stations: which one do you need?

Thin laptops keep losing ports. Plenty of current models have two USB-C ports and nothing else, and one of them is taken whenever you’re charging. A hub or dock gives you the rest back. The two terms get used interchangeably, but they aren’t the same product.

Bandwidth figures are interface maximums. Tom’s Hardware reports that Thunderbolt 5 supports 80 Gbps transfers and up to 120 Gbps for video; the 140 W charging floor is from Tom’s Guide. What you actually get depends on the port on your laptop.

For most people, the middle row is the sweet spot. PCWorld’s dock reviewer notes that laptops with AMD Ryzen chips use USB4 rather than Thunderbolt 4, and the two are essentially interchangeable, and that Thunderbolt 5 docks are currently better suited to Macs driving higher-resolution displays.

How to choose

• Check your laptop’s port first. A lightning-bolt icon beside the port, or “USB4” or “Thunderbolt” on the spec sheet, means a full dock will work at full speed. A plain USB-C port calls for a hub.
• Match the charging wattage. If the dock will also charge your laptop, its power output should meet or exceed the adapter your laptop shipped with.
• Count your displays. Multi-monitor support varies by dock and by laptop, and it’s the spec that most often disappoints.
• Don’t overlook cable length. A tethered cable that’s too short dictates where the laptop has to sit on your desk.

Chargers and power banks: reading the wattage correctly

USB-C laptops negotiate power with the charger through a standard called USB Power Delivery, so the number to compare is watts, not volts. According to the USB Implementers Forum, USB Power Delivery was limited to 100 W, using 20 V on cables rated at 5 A, until revision 3.1 raised the ceiling to 240 W.

• Spare charger. Match or exceed the wattage of the adapter that came with your laptop. A lower-wattage charger may still work, but it charges slowly and may not keep up with the laptop under heavy load.
• Cables matter above 100 W. Laptops that draw more than 100 W over USB-C need a charger and a cable rated for the higher power range. The packaging will say 240 W.
• Power bank. Look for a USB-C Power Delivery output rated close to your laptop’s adapter. A bank designed around phones will charge a laptop slowly, if it charges it at all.

Flying with a power bank

Federal Aviation Administration rules apply to every spare lithium-ion battery, including power banks. The FAA says spare lithium batteries and power banks must be carried on and cannot be checked, and sets limits by watt-hour rating:

Airlines can set stricter limits than the FAA, including on how many power banks each passenger may bring. Check with your carrier before you fly.

If your power bank lists only milliamp-hours, ABC News explains the conversion: divide the mAh figure by 1,000 and multiply by the battery voltage, usually 3.7 volts. A 20,000 mAh bank works out to about 74 Wh, and a 26,800 mAh bank to about 99 Wh. Both are under the 100 Wh line.

Do laptop cooling pads work?

Yes, but not the way their marketing suggests. When Laptop Mag tested 12 cooling pads across three laptops, the pads lowered temperatures, but in a demanding game the frame-rate gains never amounted to a full additional frame per second. The pads also added noise, measuring between 48 and 55 decibels.

PCWorld reaches a similar conclusion. It recommends cleaning dust out of an older laptop first, then trying pads while monitoring temperatures with a free tool such as HWiNFO, because results vary from one laptop and pad design to the next.

When a cooling pad makes sense

• You play or render on a gaming laptop for hours at a time, and the underside gets uncomfortably hot.
• The pad’s fans line up with the laptop’s intake vents. A pad that blows air at solid plastic does very little.
• You want a better typing angle. Many pads double as a stand.

Free fixes come first: work on a hard, flat surface instead of a bed or couch, keep the vents clear, and clean out the dust. If a fan has become loud, our guide to fixing a noisy laptop fan walks through the causes.

Headsets and headphones: wired or wireless?

Built-in laptop speakers and microphones are designed around size, not sound quality, so a headset is worth having for video calls, travel and gaming. The choice comes down to how you connect it.

• Bluetooth. No cable, and the same pair works with your phone. It needs charging, and it adds a small audio delay that you can notice in fast-paced games.
• Wired (3.5 mm or USB-C). Nothing to charge or pair, and no wireless delay. Many phones no longer have a 3.5 mm jack, so if you want one pair for everything, check both devices’ ports.
• Gaming headsets with a USB dongle. Wireless freedom with lower latency than standard Bluetooth, at the cost of one USB port.

If calls are your main use, compare microphones first. The people on the other end hear your mic, not your headphones.

Laptop security: physical locks and software tracking

A cable lock won’t stop a determined thief, but it does stop the opportunistic grab in a library, coworking space or café. The catch is that lock slots are no longer universal. Kensington, which introduced the security slot in the early 1990s, now describes three common slot standards:

Some ultra-thin laptops have no slot at all. Check your laptop’s sides for a small opening marked with a padlock icon, or look up the model’s spec sheet. Universal locks that fit all three slot types are available.

Turn on tracking today, not after it’s gone

The most effective anti-theft accessory is free, and it has to be set up before you need it. Microsoft says Windows’ Find my device feature needs to be turned on before you can use it, and requires signing in with a Microsoft account that has administrator rights. On a Mac, Apple notes that adding your Mac to Find My automatically turns on Activation Lock.

Remember to reverse this before you sell. A laptop that is still tied to your account can’t be reset by its next owner. Our guide to protecting your privacy when selling a laptop covers the full sign-out checklist.

Resale value: how accessories protect what your laptop is worth

Laptop accessories themselves are rarely where the money is. Their value is in what they prevent: a scratched lid, a cracked display, a keyboard worn shiny, a battery aged early by heat. Those are exactly the things that separate a top-condition quote from an average one.

When it’s time to upgrade, Gadget Salvation buys used laptops directly, including MacBooks. There’s no listing to write and no buyer to negotiate with. Each quote is priced to live market data and made case by case, and the offer is locked before you ship. You can follow the whole process on our how it works page. If you still have the original charger, keep it with the laptop, and before you send anything, follow our guide to cleaning and resetting your laptop before selling.
