45 W multi-voltage AC adapter

This BTI adapter delivers 45 W across four selectable DC outputs: 5 V, 12 V, 15 V and 20 V. It suits portable media players and similar accessories that require one of those voltages. The compact black housing fits easily in a travel bag.

Capacity and headroom

At 45 W the unit handles most single-device charging tasks for supported players. It cannot power larger notebooks or multiple accessories simultaneously. Headroom is limited to the rated output for a single compatible device.

5 V, 12 V, 15 V, 20 V selectable output

The adapter switches between four fixed voltages, so the connected device must accept one of these exact levels. Buyers whose equipment needs a different voltage or a higher wattage cannot use this model.

Questions about this item

Will this 45 W adapter power my older 5 V DC MP4 player safely?

Yes, it supplies 5 V DC along with 12 V DC, 15 V DC and 20 V DC outputs, so a 5 V device will draw the correct voltage.

How can I confirm the adapter is delivering 20 V DC after I plug it in?

Use a multimeter on the DC plug; a reading near 20 V DC shows the highest rail is active.

Does the box include interchangeable tips for different MP4 models?

The package contains only the black 45 W adapter unit; any specific connector tips must be purchased separately.
