Dell 9 V USB-C Power Adapter

This Dell TBFFDTC adapter converts a vehicle DC supply into a stable 5 V output through dual USB ports. It accepts an input range of 12 to 24 V and delivers up to 15 W of regulated power. The compact module suits drivers who need to charge phones or tablets from a car socket.

Dual USB output and high efficiency

Two USB ports share a combined 3 A current limit while the converter operates at up to 92 percent efficiency. A switching frequency of 340 kHz helps maintain low heat across the 8 to 36 Vdc input span. The unit functions reliably from minus 40 to plus 80 degrees Celsius.

Check vehicle voltage and port fit

Verify that your vehicle supply stays within the 8 to 36 Vdc range before connecting. Ensure the straight-headed mini plug matches the accessory socket geometry. The 45 by 26 by 12 mm body should clear surrounding trim without obstruction.

Questions about this item

Will the DC-DC converter module need any maintenance or replacement parts over time?

The sealed solid-state module has no user-serviceable parts and no moving components, so it does not require scheduled maintenance or consumable replacements.

What limit appears first when the adapter runs continuously at full 15 W output?

The thermal ceiling of the enclosure is reached first; at 92 % efficiency the dissipated heat raises the case temperature until the -40 °C to +80 °C operating window is approached.

How much noise and heat does the adapter produce when powering a load all day?

The 340 kHz switching frequency is inaudible, and with 92 % efficiency only a small fraction of the 15 W becomes warmth that the compact 45 × 26 × 12 mm case must dissipate.
