What this adapter powers

The BTI 45W USB-C AC adapter delivers 45 W of power through a USB-C connection, making it suitable for charging compatible portable media players and similar devices. It accepts a wide input range of 120 V AC or 230 V DC, so it works across different regional power supplies. The unit is supplied new in black.

Build and daily use

A fixed USB-C cable provides the output connection, removing the need to carry a separate lead. The adapter supports multiple output profiles including 5 V at 3 A, 9 V, 12 V, 14.5 V, 15 V and 20 V DC, allowing it to negotiate the correct voltage with the attached device. Its compact form factor fits easily into a travel bag.

The deciding specification

The 45 W maximum output determines whether this adapter can charge your specific device at full speed. Check the power requirement of your MP3 or MP4 player before purchase; units needing more than 45 W will charge more slowly or not at all. Model number 934739-850-BTI identifies the exact part.
