Protectors with current up to 15A can be used normally, while protectors with currents less than 12A can't be used.-The plug should be inserted tightly during use to maintain good power supply. Do not touch the metal of the cigarette butt with your hands when pulling out the plug after long-term use to avoid burns.How to determine whether current flow is limited and how to solve it:-For trucks with limited current flow, you need to check the logo on the cigarette lighter port, and it can be used if the power is greater than 200W. If 24V and current is marked, multiply the two. Result greater than 200 can be used. If there is no mark, the flow is limited. -You can find a master electrician or go to a repair shop to modify the cigarette lighter wire and directly connect it to the cigarette lighter, bypassing the current limiting device.-You can use a direct connection line, lead the wire from the battery, and connect the two wires for normal use.
