Motomaster 300 Amp Power Pack
300 cranking Amps
Equipped with 12 V accessory plug
Can be used as both a booster pack and a 12-volt DC power source
Manual on/off switch
So, I assumed you do not have an access to AC power. Am I correct?
Is this power pack you are talking about a self contain 12VDC Battery? If that the case, I don't really understand what Sosidge is talking about "it's won't be a smooth supply".
If the Battery doesn't have a smooth DC output I don't know what else will. Not even a $21,000 switching power supply that I am using in my office as smooth as Battery.
The bottom line is, if the power pack you are talking about contain 12VDC battery and have a direct output from Battery.. Go for it.
