Summary#
The Steam Frame accessories that matter from day one are storage and power: the base headset ships with just 256GB, and a proven UHS-I microSD card plus multi-port USB-C charging fix its two real gaps. This guide only lists gear whose Frame compatibility is already certain.
Valve's headset arrives with a lot in the box — a wireless adapter, a pair of motion controllers, and a head strap with a built-in 21 Wh battery. What it doesn't come with is room, and a VR-ready library eats 256GB fast. The good news: the right storage and power picks can be bought before the headset even lands, because they follow from Valve's own published specs. We'll expand this guide as the Frame's accessory ecosystem fills in.

The First Upgrade Is a microSD Card#
The Frame's single best feature for storage is its microSD slot. It reads UHS-I cards — the same class as the Steam Deck and Steam Machine — and SteamOS shares card libraries across devices, so a card you set up on any of them drops into the Frame with its games ready to play. Valve's engineers say cards formatted for SteamOS show up immediately across the family, and that SD storage "actually works really well" in their testing.
The SanDisk Extreme microSDXC (View on Amazon) is the proven pick: A2-rated for the random reads that drive load times, tough enough for a device that travels, and trusted by years of Steam Deck use. One warning that saves money: skip the new microSD Express cards — the Frame's slot is UHS-I, so Express cards fall back to UHS-I speed and you pay for performance the reader can't use. We compare the three cards worth buying in our best microSD cards for the Steam Frame guide.
The 256GB Frame + a 1TB Card Beats Paying for Internal Storage#
Here's the math worth doing before you pick a Frame model: the gap between the 256GB and 1TB headsets buys a lot of microSD card. The Lexar Play 1TB (View on Amazon) takes the base Frame past the big model's built-in space in one move — and unlike internal storage, the card travels to a Deck or Machine whenever you want your library somewhere else. Internal storage still loads fastest, so heavy favorites belong there; but for holding a big backlog, capacity-per-dollar is firmly on the card's side.
One Charger for the Headset, Controllers and Everything Else#
A standalone headset turns into a small charging station's worth of devices: the headset itself, its battery head strap, two motion controllers, and probably the Steam Deck and phone next to them. A multi-port GaN brick is the tidy answer. The Anker 735 (View on Amazon) pushes up to 65W across three ports, which lets one wall outlet top up several devices at once instead of rotating them through a single charger — we've reviewed it in detail in our Anker 735 charger review.
Valve hadn't published the Frame's final charging specs when we wrote this, so treat the in-box kit as the baseline and a multi-port USB-C PD brick as the desk upgrade; we'll update this section once the Frame is out and the numbers are official.
Power Away From the Wall#
A 21 Wh battery in the head strap is good news, but any wireless headset session eventually ends at a cable — and on a trip, the wall outlet is never where you are. A compact USB-C power bank like the Anker Nano (View on Amazon) keeps sessions going: 10,000mAh of capacity with 45W output, small enough to live in the headset bag.
It's just as useful for the rest of the kit — the Deck, the controllers or your phone between sessions. Our full Anker Nano power bank review covers the details.
What We're Not Recommending Yet#
Cases, face gaskets, replacement straps and charging docks are the accessories everyone will ask about — and they're exactly the ones we're not listing yet. They have to fit the Frame's actual shape, and until the headset is in people's hands, "compatible with Steam Frame" is a promise no third-party listing can prove.
This page deliberately sticks to what's already certain: the microSD slot is UHS-I per Valve's published specs, and USB-C power is the standard across Valve's whole hardware family. Once the Frame ships and the real accessory ecosystem lands, we'll add the fitted gear that's actually worth buying — the same way we did for the Steam Machine in our best Steam Machine accessories guide.
Pros & Cons of Kitting Out Early#
Pros
- The storage and power picks here are ecosystem purchases — they serve a Steam Deck, Steam Machine and phone today, and the Frame the day it arrives.
- A microSD card bought now carries your SteamOS library into the Frame on day one, with zero setup beyond plugging it in.
- Multi-port charging solves a real problem every standalone headset owner hits: too many devices, one charger.
Cons
- Fitted accessories (cases, gaskets, straps) can't be verified yet — anything claiming Frame compatibility before launch is guessing.
- Valve's final charging specs weren't published at the time of writing; the in-box kit may cover more of your needs than expected.
- If you only ever play tethered to one room, a power bank adds little.
Final Verdict#
Buy the boring things first. A proven UHS-I microSD card — the SanDisk Extreme (View on Amazon) for most people, the Lexar Play 1TB (View on Amazon) if you want the storage question closed — is the one Frame accessory that's already fully certain, thanks to Valve's shared-library design across SteamOS devices. Add a multi-port GaN charger and a compact power bank and the whole kit — Frame, controllers, Deck, phone — stays charged from one outlet at home and one brick on the road. The fitted gear can wait for launch day; the storage and power can't be wrong.
