Problems laptop charging through power inverter

Lukas Michalek · Jun 30, 2016

So i used to drive a cab with a little netbook. Had a 150w power inverter for it. It ran fine. I startes truck driving now and my laptop wouldnt charge through the inverter. I tried it on an outlet and it charged fine. I bought a 300w power inverter thinking the old one went bad, but nope. Same problem. These trucks can power a minifridge and a microwave but cant charge a little netbook? The power inverter turns on and the usb ports give power. But the laptop wont draw power from it. Anyone have any clues? Cuz i know the power inverter is more than strong enough, the laptop charger works. Im completely out of ideas. Does anyone have any suggestions?

Welcome to TPU!

Have you verified those power inverters are putting out stable power?

Have you tried another laptop/charger to see if it might be an issue with your charger being sensitive?

What quality of inverter are you using? Wattage is only part of the puzzle...if its cheap garbage then I'd recommend moving up to something of better quality.

I've done what you're trying to do many times...and have issues with cheaper inverters...which should be expected...you get what ya pay for. But a mid-grade one was able to handle two laptops at once. I believe its a 430W unit. Has fuses, master power switch, cooling fan, large heat sink body, etc.

I'd check the cable from the inverter, see if it's putting out the proper charge for the lap top. As you stated it does charge from a wall socket, can you try a cigarette charger on it?
