Review conclusionWith reservationsWith reservations

Only in one review: Voltage 68 V (68 V 600 W power supply); Power 600 W (68 V 600 W power supply); No load 6 W (68 V 600 W power supply); Weight 1200 g (68 V 600 W power supply); Price 27 $ (12 Volt 50 Amp power supply).

68 V 600 W power supply: After modifications, the author considers it acceptable, but notes hot snubbers, fan noise and unstable output voltage.

12 Volt 50 Amp power supply: It delivered 595 W in a one-hour test, but sustained power is likely only 450–480 W, with some components overloaded.

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.
