Only in one review: Voltage 5 V (5 Volt, 6 Amp, 6-port charger with charging-current indication); Current 6 A (5 Volt, 6 Amp, 6-port charger with charging-current indication); Under load 4.66 V (5 Volt, 6 Amp, 6-port charger with charging-current indication); Temperature rise 66 °C (5 Volt, 6 Amp, 6-port charger with charging-current indication); Price 21.99 $ (5 Volt, 6 Amp, 6-port charger with charging-current indication).
USB charger (power supply) 5 V 3 A: The claimed 3 A is overly optimistic; the author recommends loading it to no more than 2 A.
5 Volt, 6 Amp, 6-port charger with charging-current indication: A well-designed charger with useful current readouts, but untidy assembly and an overstated per-port current rating.
