Level 1

Level 2 (default)

Level 3

By Booster Stages (2X, 3X, 4X, 5X, 6X, 7X, 8X) and Booster Efficiency (Level1~3) commands, we

could easily set the best Booster performance with suitable current consumption. If the Booster

Efficiency is set to higher level (level3 is higher than level1). The Boost Efficiency is better than lower

level, and it just need few more power consumption current.
