Power, Docks & TDP
Battery life and docked performance are the same story told twice: power. This hub connects the dots — how much a handheld actually pulls at each TDP, why a peak-wattage headline never survives a real session, and what PD wattage a dock needs to charge and drive a display without throttling the device. Buy the plumbing (docks, banks, chargers) as deliberately as the handheld.
Where to start
- Best Docks & HubsDocks, hubs, and PD wattage — what it takes to drive a big screen without throttling the handheld.
- Best Power & ChargersPower banks, PD chargers, and battery math — the wattage a handheld actually pulls at each TDP.
- Best PC HandheldsSteam Deck, ROG Ally, Legion Go class — graded on battery bands at real TDP, not peak-wattage spec sheets.
Glossary terms
- TDP (Thermal Design Power)
- The wattage a chip is set to run at — the single biggest lever on battery and performance.
- USB Power Delivery (PD) Wattage
- The wattage a charger or dock can supply — must exceed what the handheld draws.
- Dock
- A base that turns a handheld into a small console on a TV or monitor.
- Battery Capacity (Wh / mAh)
- The size of the tank — meaningful only against the device’s watt draw.
- Thermal Throttling
- A chip cutting power to shed heat — the reason peak performance never lasts.
