Only in one review: Under load 15.1 V (Sanmim GPN30E-15); Efficiency 82 % (Sanmim GPN30E-15); Protection 4.2 A (Sanmim GPN30E-15); Price 6.76 $ (Sanmim GPN30E-15).

Sanmim GPN30E-15: It handles a twofold overload steadily with moderate heating; its main drawback is the cheap terminal blocks.

5 V 2 A power supply with microUSB plug: Works acceptably up to 1.5 A, but voltage sags above that and it can interfere with some touchscreens.
