Why customers choose TaskHolt Tools

Bridge your Dewalt generations with a single adapter

The BTRUI adapter reimagines how you use power tools by letting a 20V Dewalt Li-Ion battery run 14.4V/12V Ni-MH tools. Rather than buying a separate battery, this converter provides a practical path to reuse what you already have, turning a single power source into more flexible tool operation.

Designed with real-life workshop scenarios in mind, this unit helps you squeeze extra life from older or lower-cost 12V tools by pairing them with a familiar 20V battery. The result is not a guaranteed outcome for every task, but it opens up possibilities to test and complete projects without changing your current battery inventory.

Key advantages

  • Voltage step-down from 20V Li-Ion to 14.4V/12V Ni-MH for compatible tool operation.
  • Expands options by enabling use of a single 20V pack with select 12V Ni-MH tools.
  • Compatibility with a wide range of 20V Dewalt packs, including common models used in cordless tools.

Solid build and safe design

  • Constructed from durable ABS plastic for everyday use and portable handling.
  • Important usage note: this is not a charger; always use your original charger to recharge batteries.

Usage tips and scenarios

Attach a 20V battery to the adapter, then connect a compatible 14.4V/12V Ni-MH tool. It’s ideal for quick testing, field maintenance, or workshop tasks where a single battery supports multiple tools.

Performance can vary by tool and battery chemistry. The adapter does not modify charging circuits; charging should occur with the original equipment.

With its compact form, you can stash it in a tote or toolbox and switch between projects without hunting for a new battery setup.
