eSMART DUO cable input assembly

To deliver maximum versatility in demanding audio workflows, Audioroot offers five user-installable input cable harnesses for the eSMART DUO smart power distributor. These modular cables allow for easy customization to suit your preferred power sources—whether legacy batteries or modern USB-C.

Installation is quick and easy—only a TX8 and a TX10 screwdriver are required.

Available Cable Options:

• DUO-CAB-TT (Pre-installed by default)
  Features 2 x TA4M connectors (8 cm length), compatible with Switchcraft-format smart batteries. Ideal for conventional smart battery setups.

• DUO-CAB-CU
  Features 1 x smart battery cup and 1 x USB-C PD input, allowing flexible powering from modern USB-C adapters.

USB-C Power Delivery Input

The USB-C PD input allows the eSMART DUO to be powered from a USB-C Power Delivery (PD) supply. A minimum of 15V PD profile is required for operation. However, for optimal performance, we highly recommend a 20V/5A capable PPS-compatible USB-C power supply, which enables the DUO to run at 17.0V.

At 17V, your equipment draws power primarily from the USB-C source, preserving your 16.8V lithium-ion battery for backup. In case of AC power loss or USB-C disconnection, the DUO automatically switches to battery power without any interruption—ensuring uninterrupted operation in the field.

Recommended PPS-compatible USB-C power supply models include:

• SIIG AC-PW1N11-S1
• SIIG AC-PW2511-S1
• SIIG AC-PW1X11-S1
  
• SIIG AC-PW1P11-S1
• Baseus CCDK100UE
• Verbatim 32202
• QODJN HX-P23
• UGREEN X764
• eSTUFF ES635201
• ANKER 250W prime charger A2345
• NexTECH 280W GaN charger
• Chargeasap 280W Zeus USB-C GaN Charger

Please note that the Verbatim 32201 (65W USB-C charger) is NOT recommended as it is unable to deliver 17V DC in PPS mode.
