Advantage 01
Dual adjustment via Bluetooth screen — one unit fits many battery types
With an optional Bluetooth display, charging voltage and current can be adjusted from a phone without opening the case. Aftermarket battery specs vary widely, so one unit covers multiple voltage platforms — drivers can adjust it themselves, with no need to send it back to the factory.

efficiency comparison 92.8% → 94%
New-gen power solution + dynamic dead-zone
Advantage 02
Brand-new power solution, efficiency up to 94%
A brand-new high-efficiency power solution replaces the older second-generation devices, and dynamic dead-zone control replaces fixed dead-zone control, raising conversion efficiency from 92.8% to up to 94%. Higher efficiency means lower heat and reduced loss, delivering greater stability over long-term use.

32-bit Cortex MCU
Far faster than typical 8-bit solutions
Advantage 03
32-bit Cortex MCU — faster processing
The secondary side uses a 32-bit Cortex-M0 core MCU, whose processing speed and resources far exceed typical 8-bit solutions on the market, providing computing headroom for multi-stage charging algorithms and complete protection logic, with stronger expansion capability.
