The maximum total current that the splitter can supply is 8 Amps (provided your car cigarette lighter socket is fused and wired to be able to provide at least 8 amps). Some examples to help:
- CB radio into plug 1 uses 1 amp and peaks at 4 amps (when transmitting)
- GPS into plug 2 uses 1 amp
- Inverter into plug 3 uses 5 amps
Each one is less than 8 amps, but the total when you don't talk on your CB radio is 7 amps so okay, but not okay when you talk on your CB because then the total is 10 amps.
So while it says each one can do up to 8 amps, the whole thing can only do 8 amps.
Hope this helps you understand :)
