Only in one review: Voltage 12.6 V (12.6 V 1 A charger); Current 1 A (12.6 V 1 A charger); Ripple 700 mV (USB charger (power supply) 5 V 3 A); Temperature rise 155 °C (12.6 V 1 A charger).

12.6 V 1 A charger: Unmodified, it overheats and shuts down; reducing the current to 700–750 mA makes it run much cooler.

USB charger (power supply) 5 V 3 A: The claimed 3 A is overly optimistic; the author recommends loading it to no more than 2 A.
