Only in one review: Under load 5.16 V (Quick Charge voltage converter); Temperature rise 60 °C (Quick Charge voltage converter); Price 1.34 $ (Quick Charge voltage converter).

USB DC-DC board, type two: Type two works but overheats, is limited to about 2.8 A, and has worse efficiency and ripple than type one.

Quick Charge voltage converter: A compact, inexpensive QC converter, but ripple is high and it cannot sustain maximum 5 V load for long.
