Input and
Output:
Input: AC 100~240V, 50/60Hz;
Output: DC 3~24V adjustable, maximum 3A 72W. It can supply any voltage between 3~24V, such as 3V, 4V, 4.5V, 5V, 5.5V, 6V, 9V, 12V, 14V, 15V, 19V, 20V, and 24V, as well as any current below 3A, such as 300mA, 500mA, 1A, 1.5A, 2A, 2.5A, and 3A. The LCD displays the output voltage to help prevent device damage caused by incorrect voltage regulation.
Upgraded Power Supply: The knob can be adjusted smoothly and can reach 13V ~ 14V by rotating 50%. An off position allows the power to be turned off without unplugging the adapter. A polarity converter cable provides compatibility with more devices and expands its application range.
14 Frequently Used Tips: Includes an original 5.5 x 2.5 mm tip and 14 frequently used tips: 6.5 x 4.4 mm+Pin, 5.5 x 2.1 mm, 5.5 x 3.0 mm+Pin, 5.0 x 2.5 mm, 6.3 x 3.0 mm, 5.5 x 1.7 mm, 4.8 x 1.7 mm, 4.0 x 1.7 mm, 3.5 x 1.35 mm, 3.0 x 1.1 mm, 2.5 x 0.7 mm, Micro-USB, Type-C, and a DC terminal connector. It can be applied to almost all commonly used electronic devices. Wires can be screwed onto it easily for DIY projects.
Wide Range of Applications: The 72W all-in-one multipurpose AC/DC adapter fits many 3~24V small household electronics, including LED strips, under-cabinet lights, TV boxes, smart speakers, wireless routers, essential oil diffuser humidifiers, USB fans, WiFi cameras, USB hubs, hard disk boxes, DC motors, DC pumps, digital photo frames, and DVR NVR surveillance systems. For indoor use only.
Safety Protection Systems: Built-in multiple safety protection systems include automatic over-voltage, over-current, over-temperature, and short-circuit cut-off. The adapter operates without noise and includes protection against spontaneous combustion, explosion, and fire hazards. The 6ft power cable provides convenient use.
Important Note: Choose the correct voltage before connecting the adapter to your device. Incorrect voltage may damage your device. Use less than 80% of the full load
