WAWEIS AC Adapter 100-240VAC 10Ft Cord

SKU CH-B0HB-TB35V

A replacement AC adapter with a 10 ft cord, 100-240 VAC input, and DC output options of 12 V, 15 V, 19 V, 24 V, or 35 V for compatible audio amplifiers

  • World-wide 100-240 VAC input works across regions
  • 10 ft total cord length gives flexible placement
  • FCC, CE and RoHS certifications confirm safety compliance
  • Over-current, over-voltage, short-circuit and total-power protections guard equipment
  • 100 % OEM-compatible replacement matches original device specifications

Purpose and audience

This AC adapter replaces the original power supply for Fosi Audio mini amplifiers such as the TDA7498E, BT20A, TPA3116, BT10A, BT30D and BL20C models. It suits owners who need a direct replacement for a lost or damaged charger. Buyers looking for a universal laptop charger or a higher-wattage unit for other devices should look elsewhere.

Input voltage and cord length

The unit accepts a worldwide input range of 100-240VAC at 50/60Hz, so it works on mains supplies in most regions without a separate voltage selector. A single 10 ft power cord is integrated, giving a fixed reach from the wall outlet to the amplifier. Users who require a detachable IEC lead or a longer cable run will need an alternative solution.

Output voltage range and protection

The adapter delivers a DC output adjustable across 12V, 15V, 19V, 24V, 30V and 35V, matching the requirements of the listed Fosi Audio amplifiers. Built-in safeguards include over-current, over-voltage, short-circuit and total-power protection, plus a smart chip for thermal management. Confirm that your specific amplifier model operates within this voltage span before purchase.

Questions about this item

Which voltage version should I choose for my Fosi Audio amplifier?

Select the output that matches your amp's requirement — 12 V, 15 V, 19 V, 24 V or 35 V — as marked on the device label.

What does the 100-240 VAC input mean when I plug this in at home?

It accepts any mains supply from 100 V to 240 V at 50 Hz or 60 Hz, so it works worldwide without a voltage switch.

What connector standard does the DC output use and what does it limit?

The barrel plug delivers a fixed voltage — 12 V, 15 V, 19 V, 24 V or 35 V — and the built-in protection caps current if the load exceeds the adapter's rating.
