Any REAL differences here, besides the costs?

I'm in the market for two things rather quickly, first, a surge protector, second, an inverter.

I have a 2009 Navion and have had it for one year, but the last 7 months it was in storage (winter).

Here's what I found for portable surge protectors:

I see the Surge Guards from time to time, but even at the sale price, is it really any better than the Smart Surge. Yes, I know that there's no LED display and the amount of Joules is lower on the Smart Surge, but do I really need this?

Now for the inverter. I want to be able to make coffee without using the generator, also use my computer. I thought I needed a voltage converter, but I'm told they are Inverters. So, what do you think about this brand, capacity, specs and price?

I could get a 1000 wt or 1500 wt, but...

HELP PLEASE!

Thanks!
