Portable 12v battery box.

So I was trying to think of a way to get around my company's restriction against hard wiring any electrical components to the truck. Since this limits me to just the cigarette lighter sockets, even though some of the ones on my Cascadia are rated at 20 amps, this still restricts me from running much more than a 200 watt inverter. To run a microwave, I would need at least a 750 watt inverter, which probably draws around 80 amps after efficiency.
So I thought, "what if I have a separate battery and charge it with a cigarette adapter, and hook an inverter to that?" The problem is, if I was to hook a dead battery up, it would draw too many amps and blow the fuse or fry the socket while charging.

So, I did some more research, and came across this;

It is a "smart" portable battery box. It can be charged via 110ac, or 12vDC via cigarette lighter adapter, draws only 7 amps when charging, plus it has positive and negagative terminals so a big inverter can be easily connected.

What do you guys think?

 

Werner doesn't allow anything to be directly wired to the truck unless it is done by their shop, and pretty much the only thing they will hard wire for you is a CB.

The reason for this is because they had a lot of truck fires caused by shoddy electrical handywork done by drivers and shops. And inverters are well known for causing the truck to go up in flames. I'm pretty sure they don't even allow the cigarette adapter inverters unless it is an approved one for a CPAP device. They just don't strictly enforce that part of it.

A decent name brand inverter like cobra will typically have a "peak power" that is usually double it's listed wattage, so it can power through the start up phases that cause some electronics to draw higher current than usual. FYI, the RoadPro brand "Powerdrive" inverters do not have this. If you read the instructions that come in the box, it specifically says not to run the inverter at full capacity for more than 30 seconds, and then it mentions a maximum continuous wattage.
