Quick answer: Every handheld eventually collects the same three companions: a dock, a fast microSD card, and a 45W power bank. JSAUX owns the value tier of this category in 2026 - their Steam Deck dock made their name, and their new Switch 2 charging docks (~$19) and the wild FlipGo Lite stacked dual monitor (~$200) carry the streak. The handhelds themselves are ranked in our handheld gaming PC guide.
Handhelds are the fastest-growing corner of gaming - the Steam Deck price hike, the ROG Xbox Ally, the Switch 2 selling out for months straight. But the out-of-box experience of every one of them has gaps, and the accessory tier is where small money buys big quality-of-life.
The Picks
What Actually Matters (60 Seconds)
- Wattage is the spec that lies. A power bank or dock that cannot sustain 45W PD will charge your handheld slower than gameplay drains it. Check sustained output, not the sticker number.
- microSD before internal SSD if you are new to handhelds - zero risk, works on every device. Do the NVMe swap once you are comfortable, it is the better value long-term.
- Docks are about the cable mess, not just TV play - one USB-C in, everything else stays plugged into the dock forever.
- Switch 2 owners: controller charging docks are the accessory nobody plans for and everybody ends up wanting - four Joy-Cons do not charge themselves.
- Building a full desk setup around a handheld? The setup accessories guide covers the monitor-arm-and-light-bar side of the equation.
Frequently Asked Questions
What accessories does a handheld gaming PC actually need?
Three things earn their place in the bag: a dock for TV play and charging, a fast microSD card (storage fills faster than you think), and a power bank rated for 45W+ USB-C PD so you can play while charging. Everything else is taste.
Do Switch 2 accessories work with the Steam Deck or ROG Ally?
Chargers and power banks generally yes - it is all USB-C PD. Docks are hit and miss: video output works on most, but charging wattage and fit differ. Controller charging docks are console-specific.
