The MLB main unit does not require 12V power.

Data Collection Time:
Good power supply: ~15 minutes for data collection, ~1 minute for immobilizer data calculation.
Average power supply: ~30–60 minutes for data collection, ~1 minute for calculation.

Use two USB cables.
 
Connecting to a Tablet:

Label 2: Tablet power quality is insufficient. For better results, connect the OBD to the vehicle or supply external power to the OBD to maintain tablet battery.
Note: Tablets with a single Type-C port have poor power stability, leading to longer collection times and lower success rates. Strongly recommend using a PC.
