Looking for a reliable 500w psw inverter for my offroad rig

[Airbats801]

I'm wanting to use and charge my gaming laptop while off camping, offroading etc.. I'd say the ac wattage needed would be 300w to be safe, figured a 500w would be a good area to be for charging the laptop. I'm not too concerned with idle consumption as it will be switched, and only be on when the laptop is plugged in. Power is coming from a 12v 200ah lifepo4. I mainly dont want a fireball in a case. I figured I'd ask here before just randomly buying one on amazon.

It is hard to beat the PST 12 volt 600 watt Samlex Inverter. In my opinion it is the best bang for the buck. Samlex PST inverters are known to have good reliability and durability.

Don Rowe is a good place to purchase it as well. I have bought a couple of inverters from them with no problems. They are known for their good support.

You might want to skip using an inverter if its only use will be charging a laptop. You may be able to charge the laptop directly from the 12V LiFePO₄ battery. If there is a way to charge your laptop using a standard 12V plug in a car then you don't need an inverter. This will save you money and it will be more efficient use of your battery.

Your laptop is DC. Avoid doing DC -> AC (via inverter) and then AC -> DC (via the laptop's power cord "brick") when possible.

My brother has a VOLTWORKS 600W pure sine wave inverter, including a pair of battery clips and LCD display,very easy and safe,maybe you can look details as below

i have had decent experience with 300W giandel pure sine wave inverter. they offer a 600W one too, but have not tested it yet.

also have had a great experience with victron phoenix 500(W/VA) pure sine wave inverter.

the giandel one is lighter and uses high frequency inversion with MOSFET which will be fine with laptop charger because no surge.

the victron one is heavier and uses low frequency with toroid coil and is supposed to work better with surges.

victron 500W

having used the 300W giandel to charge laptop, it might be suitable for your stated power needs. it has a small fan inside that activates when load is more than like 100W. it's fairly quiet but being nearby it is audible.

hope this helps, good luck with your project

I already looked into this. it uses a hefty 280w power supply and they do not make any kind of dc to dc setups. THe dc to dc inverter I was looking at was quite expensive.

Thanks for the replies everyone, It looks like I have a few options. I'm thinking about the victron, but might give one of the other ones a go.
