KEHIPI AC 110V/220V to DC 5V 20A 100W Power Adapter

SKU CH-C9BT-RNFD8

Converts 110V or 220V AC to adjustable 5V DC at 20A with dual outputs and full protection

  • Dual 110V/220V input suits global mains supplies
  • Adjustable ±15 % output fine-tunes voltage for sensitive loads
  • Four protection circuits guard against over-voltage, overload, over-current and over-temperature
  • Two independent channels share 20 A 100 W total for flexible device powering
  • Indoor-rated switching design powers LED strips, CCTV and automation gear

KEHIPI 5V 20A 100W Switching Adapter

This regulated switching power supply converts AC 110V or 220V input to a stable DC 5V output with a maximum current of 20A and 100W total power. It features two independent output channels for powering multiple devices simultaneously. The unit is designed for indoor use only and suits applications such as LED strips, CCTV cameras, and computer projects.

Check input selector and load limits before wiring

A black switch on the unit selects between AC 110V (left) and AC 220V (right); set it to match your mains voltage before connecting power. The maximum continuous load should not exceed 80% of the rated capacity, so plan for devices drawing up to 16A or 80W combined. Output voltage is adjustable by ±15% via a yellow button for fine tuning. No installation instructions, cables, screws or an on/off switch are included, and professional installation by a qualified electrician is recommended.

Two channels share the 20A 100W budget

Both output channels draw from the same 20A 100W limit, so total connected current must stay within that boundary. The adapter provides over-voltage, overload, over-current, over-temperature and short-circuit protection; if protection triggers, unplug the AC cable, wait about 10 minutes for auto-recovery, then reconnect. High voltage is present inside the enclosure, so do not remove the cover. Dust the unit every two or three months to maintain reliability.

Questions about this item

Does the box include any cables, screws or an on/off switch?

The package contains only the power supply. No installation instructions, wiring cables, on/off switch or screws are included.

How do I select the right input voltage for my region?

Use the black switch on the unit: left position for 110 V (USA/CA), right position for 220 V. Set it before plugging in.

What does the 20 A 100 W rating mean for everyday use?

Each channel can deliver up to 20 A, but total combined output is limited to 20 A 100 W. The manufacturer recommends staying below 16 A (80 W) for longer lifespan.
