Laptop power inverter?

Question

I see vehicle power inverters designed for laptops. They are a lot more expensive than regular inverters. What's the difference? Can I use a regular power inverter for a laptop?

Answer 1

YES, Since most laptop power supplies are DC out they already have some protection against spikes etc.

An inverter will convert your cars DC into AC which will then power your AC converter for your laptop which will then output DC for your laptop to use. The other question might be, do you even need the inverter in this case. Many companies make DC power cords so you can connect your laptop directly into the cars power plugs without any need for power inversion of any sort.

And if the company that makes it says it is for a LAPTOP they can charge you more.. that is the main difference. (OK some do add additional filters but again since your laptop has an adapter in the first place how much filtering do you need!!)

Answer 2

it may harm the inverter and blow a number of the fuses on the circuit. Wattage measures the optimal power a gadget could draw. It would not continuously decide on that power, yet, while it does, and the circuit can't furnish, fuses would be blown or, if incorrect fuses used, issues will capture on hearth. Now, many computer adapters those days are rated for a hundred and ten-240 Volts at 50-60-HZ. examine if yours is like that. if so, then the inverter isn't mandatory. EDIT: in case your computer's power brick says "a hundred-240v 50-60Hz." then you definately could purely plug it into US circuits with out hardship. All you decide on is a plug adapter, yet no longer an inverter. those plug adapters decide for some money at return and forth shops. EDIT 2: Do you need to run this off of a automobile inverter for 13h? it somewhat is an entire new can of worms. those "wattages" are often meant as "top" and not non-provide up.
