Only in one review: Current 20 A (Tenpower INR21700-50SG); Capacity 4931 mAh (Tenpower INR21700-50SG).

Tenpower INR21700-50SG: Mid-range cells without standout current or capacity, but they work well and may, in the author's view, deliver over 20 A.

Sony/Murata US18650VTC4: Quality high-current cells; at high discharge currents, their advantage over the Samsung 20S nearly disappears.
