Many docks and stands are designed to charge up to four Joy‑Con controllers at the same time.
Listings show both USB‑A and USB‑C connection types. Some grips include a USB‑C play‑and‑charge cable and list the cable length (commonly about 3 feet) in the product details.
Some grips combine left and right Joy‑Con into a larger controller and include play‑and‑charge capability, allowing you to use the controllers while they charge.
Many chargers use magnetic docking or magnetic‑hold designs so Joy‑Con controllers attach securely while they charge.
Warranty coverage varies across listings, ranging from a 90‑day limited warranty up to a 2‑year limited warranty; 1‑year warranties also appear commonly. Confirm the specific warranty period and terms on the product page before purchase.
