Anyone use gaming or workstation laptop?

[John61CT]

my fridge is 2.5 amp.

The average AH over 24hrs is what's important.

Amps will vary from one minute to the next.

I've recently run into the issue of connecting an inverter to my RV and having it pull the voltage down enough (even on full batteries) that the low battery alert on the inverter goes off and it keeps cycling. I can't work on either laptop with that constant noise. I'm not sure what I'm going to do at this point.

:s

Poops. I just ordered a 90w universal charger off amazon. Is that going to work?

 

[Theiznezz]

What games you guys play? I been on civ 6 a lot and pillars of eternity

really dont play games.... world of tanks is about it...

I use the gaming laptop because I do photography and need power for editing..

I used to play World of Warcraft and Call of Duty: Modern Warfare 3. But I got rid of the gaming rig for a Video Editing Laptop.

what setup do you have? do you use a 12v charger? or charge off your converter when necessary...?

Mostly I have been where there is electric, but when boondocking I tried to run or even charge my laptop from a 150W Inverter I got from Love's. Big mistake! See my Tweet on it: 

I bought a 400W inverter from Walmart. It works in my truck, however in my RV it drops the battery voltage down enough when it kicks on where it trips the low battery alert. From there is beeps and then disconnects and the battery voltage comes up and we get caught in a loop. So now as I travel I allow the laptop to charge in the car until I solve this issue.

good to know... whats your solar wattage?

good to know... whats your solar wattage?

Now you're just embarrassing me.

This RV came with a mere 90W solar panel and an 8A solar controller. Once I get into AZ I will be upgrading at Discount Solar. After seeing Carolyn's RV Life video about her upgrade I think I am going to do the same thing.

But solar aside...I am surprised that the voltage drops so much for such a seemingly small load. This means I can't run anything at night off the inverter even if I do get my solar upgraded.

So any of you have experience with the universal 90w chargers?

how much solar are you upgrading to?  Im hoping to put a min. of 400w on the roof of my TT... make some brackets so I can raise one side to get more sun.. and also a quick disconnect if I need to take them off.. all in the planning stage right now... will put into motion as soon as I find a good TT....

An inverter - or any high amps load - pulling down voltage that much means the bank is either

too small,

not getting fully charged,

old and worn out, or all three

A big fresh AGM holds voltage higher for longer than FLA, but no lead comes close to LFP for that.

There's nothing special about computers as load, everything is volts and amps, they just burn a lot of AH per day if you use them for hours.

You need to increase your knowledge and buy the right gear so you **know** what's going on, and balance your AH outgo each day with x1.2 charging AH.

For sure need an ammeter and DMM, a full-fledged BM helps make it easy, but none of this is cheap.

Same with your 12V converter / charger, you need to measure if your PC needs over 90W, no one else can tell you.

I looked at my ac adapter . it just says 19 v 6.32 a.output
Input 100-240 2.0a

 

[highdesertranger]

19 volts x 6.32 amps = 117.8 watts. highdesertranger

 

[Theiznezz]

Oh. Thanks. So what happens if I use it? Will it charge slow or damage my laptop?

 

[John61CT]

If both your 12V and PC battery start off fully charged, and

the 12V power supply is plugged in, start using it as usual. Keep an eye on it, don't let it get crazy hot.

If you see the batt SoC% dropping, then you need more amps.

If only the 12V battery's being drawn down, then really crank up usage, run benchmarking tools, play / edit videos, see if can drop the laptop's SoC.

If not, you're all set.

my regular laptop output is 19v -2.37a  = 45w havent checked my gaming laptop.. Im afraid to LOL

 

[John61CT]

The max rating of the transformer will be higher than consumption.

Which also varies widely depending on what you're doing.

Even if full-on 3D hires gaming uses 150W, just browsing, messaging etc may average only 10-20W.

Thanks for the feedback. I'm still waiting on delivery. So when I get it Ill just keep an eye on it to see how it does.
