Only in one review: Voltage 5 V (5 Volt, 6 Amp, 6-port charger with charging-current indication); Power 30 W (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); Ripple 140 mV (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).
U2: Supports four battery types and charging up to 2 A, but has current spikes and may overcharge LiFePO4 after a power interruption.
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.
