In the cylindrical lithium-ion market, the industry has standardized on the 21700 format (21mm x 70mm), which offers significantly higher energy density and capacity (up to 5000mAh) compared to legacy 18650 models.

B2B wholesale prices for 21700 cells currently range between $0.99 and $1.90 per cell, while retail demand on platforms like Amazon is driven by high-power flashlights and fast-charging power banks.
