Only in one review: Test current 7 A (DC-DC converter board, 0–30 V, 0–8 A); Under load 10.09 V (DC-DC Step Down module rated at 10 amps); Price 20.93 $ (DC-DC converter board, 0–30 V, 0–8 A).

DC-DC Step Down module rated at 10 amps: Suitable for undemanding loads up to 6 A, but its output voltage is unstable and it is unsafe for charging lithium batteries.

DC-DC converter board, 0–30 V, 0–8 A: A capable board with useful features, though using a ready-made power supply is simpler.
