Essential accessories for handheld PCs: comfort, control and protection

Portable PCs like Steam Deck, Asus ROG Ally and Lenovo Legion Go have turned high-end play into something you can carry in a backpack. Out of the box they are impressive, but a few well selected extras can make them far more comfortable, flexible and durable.

This guide looks at add-ons that genuinely improve everyday use: better control, cooling, audio, storage and protection, plus what to look for before you spend money.

Protective cases and travel pouches

Handheld PCs are not cheap, and their big exposed screens do not enjoy contact with keys or crumbs. A rigid case or padded pouch is the first accessory most owners should get, especially if the device travels in a backpack or luggage.

A good case should match the exact model so the thumbsticks are not pressed down and the triggers are not constantly held. Look for a hard outer shell, soft lining and a separate pocket for cables or cards that does not touch the display.

If you mostly play at home, a slimmer sleeve can be enough. Neoprene or soft-shell sleeves slip into a drawer or onto a shelf and help keep dust away, while still preventing light bumps and scratches.

Screen protectors and comfort grips

A tempered glass screen protector is still useful even with a hard case. It adds a sacrificial layer that can take scratches from dust, sand or misplaced controllers, and is much easier to replace than the panel itself.

For a good experience, pay attention to clarity and touch response. Cheap protectors can introduce haze or rainbow effects. A precise cut that leaves space for the bezel and vents also prevents peeling at the corners.

Many players underestimate how much a grip can change the feel of a handheld. Clip-on or adhesive back grips add thickness and contour so your fingers have somewhere natural to rest, especially during long sessions.

If your hands feel cramped, look for grips with flared backs that mimic a modern controller. Those with larger hands can benefit from bulkier grip shells, while smaller hands usually prefer low-profile rubber sleeves.

Cooling stands and USB-C hubs

Portable PCs get warm, especially when pushing 3D titles at high frame rates. A simple stand that angles the device up can already improve airflow and keep surfaces cooler to the touch.

Active cooling docks go a step further. They combine a stand with a small fan and ports, and some models draw heat away from the rear of the case. This can help stabilise performance in long sessions and reduce fan noise from the internal blower.

Most handheld PCs rely on USB-C for charging, external displays and storage. A compact hub with power pass-through, HDMI and a couple of USB-A ports lets you plug in keyboards, mice and drives without constant cable juggling.

Check that the hub supports the wattage your device expects and a recent USB standard. Underpowered hubs can cause disconnects or slow charging, especially while running demanding titles.

Controllers, keyboards and mice

Built-in sticks and buttons are fine on the move, but for couch or desk play many people prefer a familiar controller or full desktop controls. Most handheld PCs pair easily with modern wireless pads and 2.4 GHz peripherals.

If you lean toward couch play, a wireless controller with low input lag and solid battery life is ideal. For desk use, a compact keyboard and mouse can turn the device into a tiny PC, while still packing enough performance for current titles.

Pay attention to receiver type. Some accessories rely on Bluetooth, which keeps ports free but can introduce extra latency. Dongle-based 2.4 GHz kits usually feel more responsive, and are often a better match for fast action.

Headsets, earbuds and audio extras

Handheld speakers often aim forward and can sound better than many laptop speakers, but they still struggle with bass and noisy environments. A pair of closed-back headphones or in-ear buds will improve immersion and avoid annoying others nearby.

Look for low-latency wireless codecs or a wired connection if you are sensitive to audio delay. Even a small lag can be noticeable in rhythm titles and shooters, so check what formats your handheld supports over Bluetooth.

A compact USB DAC or headphone dongle can also help if your device has noticeable hiss or a weak 3.5 mm jack. These add-ons bypass the internal audio circuit and can provide cleaner sound for high-impedance headphones.

Extra storage and stands for home use

Modern titles can easily consume 100 GB or more, so expandable storage is almost essential. Many handhelds support microSD cards that slot directly into the chassis, or you can use small USB SSDs for even faster access.

For internal cards, pick reputable brands with good endurance ratings so they can handle frequent installs and updates. For external drives, favour compact SSDs with solid enclosures that will not dangle awkwardly or strain the USB-C port.

At home, a dedicated stand or dock keeps the device off the table, reduces clutter and makes it easier to grab for quick sessions. Some docks also provide Ethernet, extra USB ports and display output for big-screen play.

Cables, chargers and power banks

Many handheld PCs are picky about power. Using a charger that matches or exceeds the original wattage helps avoid slow charging or battery drain while in use.

USB-C cables also matter. Longer or very cheap cables can suffer voltage drop under heavy load. Look for cables that explicitly support the same or higher wattage as the stock charger, and avoid bending them sharply near the connectors.

If you travel often, a high-capacity power bank with USB-C PD support lets you play for several more hours away from a socket. Check airline rules for battery size and keep the bank in hand luggage if you fly.

How to prioritise your accessory list

You do not need every extra at once. Start with protection, then storage, then comfort. A case, screen protector and extra card or SSD will cover most needs for the first months.

After that, pick one or two comfort upgrades that match how you actually play. Couch players benefit most from a dock and external controller, while frequent travellers will get more value from better grips, audio and a fast charger or power bank.
