Only in one review: Current 40 A (PTA-600W-12V (500 W)); In test 620 W (UPS-1000); Under load 11.947 V (PTA-600W-12V (500 W)); Ripple 150 mV (PTA-600W-12V (500 W)); Power factor 0.75 (UPS-1000); Temperature rise 105 °C (PTA-600W-12V (500 W)); Weight 11400 g (UPS-1000).

PTA-600W-12V (500 W): Low ripple and thermal protection, but poor heat transfer limits sustained operation to about 30–32 A.

UPS-1000: The UPS impresses with fast charging and robust construction, but switches to battery more slowly than specified and is noticeably noisy.

Figures were taken from the review text and checked against the quoted passages. Measurement conditions differ between reviews, so read the reviews yourself before buying. Prices at the time of review.
