Review conclusionWith reservations—

Only in one review: Voltage 12 V (QS-60-12); Current 5 A (QS-60-12); Test current 6.5 A (QS-60-12); Under load 11.15 V (QS-60-12); Ripple 200 mV (QS-60-12); No load 0.5 W (QS-60-12); Protection 6.5 A (QS-60-12); Temperature rise 108 °C (QS-60-12).

QS-60-12: Fairly decent, but in practice it is at most a 60 W unit, possibly around 50 W.

12 V 5 A uninterruptible power supply: Good as a power supply and lock controller, but its battery charging and discharge protection need improvement.
