Only in one review: Test current 2 A (5 V 2 A power supply with microUSB plug); Under load 12.43 V (АД-12-1A); No load 0.4 W (АД-12-1A); Protection 1.1 A (АД-12-1A).

АД-12-1A: This compact supply holds 1 A, but its output diode overheats at maximum load.

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.
