Chosen Solution
I just picked up this power inverter for $11 to replace a 400W 3.5A one that isn’t good enough to run my primary laptop. While the 3.5A unit would comfortably run a standard laptop, the one I previously had won’t run my primary laptop (130W/6.7A). Because of my primary laptop I decided to get a better inverter. The unit is made by Tripp-Lite and the only specs I have on it is it runs on 12V and has a 30A fuse installed with 2 outlets. The model number is PV0536. However, when I look that up it gives me a 375W model and I have a 300W model.
@nick there is definitely a PV0536 300W power inverter. What is your question about it? The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V): I(A) = P(W) / V(V) I(A) = P(300) / V(110) meaning that this would most like deliver no more than 2.5A (2.72 by calculation). To run your 6.7A laptop you need an 800W inverter.
