The longest certified passive (relatively inexpensive) 40Gbps and faster cables are 1.5m long, and AFAIK only these specific models sold by only Kensington, CableCreation, Cable Matters, and SilkLand. No other cables in this length have been shown to meet the USB specification requirements and so likely won't carry the data reliably and/or have too much resistance for high power charging. There are 2m active Thunderbolt certified cables but they start at about 3x the price of these 1.5m options. https://www.amazon.com/dp/B0FS39ZLFK https://www.amazon.com/dp/B0DQPW58Q6 https://www.amazon.com/dp/B0DW3XZ7WD https://www.amazon.com/dp/B0FB3YXRBF https://www.amazon.com/dp/B0DRP25V8T Note that these will not be as flexible as a USB 2.0 (480Mbps) cable due to the extra wires and shielding required. USB 2.0 cables have been certified in up to 4m length.
