Two models side by side: measurements taken by the author in their reviews, and their conclusions. The better value in each row is highlighted.
In brief: Based on review measurements: Energy: Tlife Power Bank (12.03 Wh vs. 11.95); Test current: Epilot E4 (4 A vs. 2.24); Efficiency: Tlife Power Bank (87.6 % vs. 86).
Only in one review: Temperature rise 80 °C (Tlife Power Bank); Weight 116 g (Tlife Power Bank); Price 11.99 $ (Epilot E4).
Epilot E4: Works well, with useful pass-through charging and replaceable cells; a modification improves efficiency, but there is no fast charging.
Tlife Power Bank: A convenient power bank with independent charging and UPS mode, but its stock efficiency is low.
