Question 1

Which circuit breaker would you recommend to protect a car battery? I'm thinking 150A.

Accepted Answer

12V x 150A = 1,800W.  That inverter provides 1,200W at most (and then only for a moment) so a 100A fuse would be 20% higher than its continuous 1,000W power rating and give enough headroom for conversion efficiency losses and other variables.   BTW, make sure you use BIG DC cables.

Question 2

Usb ports stopped charging iphones and ipads. tried different cords. non-apple usb devices still charge. any idea what the problem is?

Accepted Answer

"Apple doesn't allow"? Hogwash. I've been using non-Apple chargers and cords for ten years or more--dozens of different combinations. No problems with good quality ones.

But not all cheap cords work. Look for a cord that's labeled "MFI" (made for iPhone)--those are certified by Apple to work properly. Not that they are the only ones that will, but they're a sure bet.

Anker chargers and cords are also safe bets, in my experience. Just stay away from the cheap plastic cords and chargers sold at the checkout counter in convenience stores. The cords may or may not work, and some of the cheap chargers can actually be dangerous fire hazards.

Question 3

Can I use it with a 110v vacuum?

Accepted Answer

Very likely not. Traditional vacuums - the kind that are so loud they scare the cats - use a very large amount of juice (near the 15-amp limit of the outlet, so they'd approach 1800 watts), but you use it over a short time, so it doesn't really affect your power bill like an air conditioner (that uses a lot of juice over a long period). You ought to just get a modern lithium battery-powered vacuum. They run long enough and are darn near just as powerful as the wall-powered ones, and cost around as much as this inverter does.

Question 4

Is the power button a physical push in & push off switch? If not, is there a small amount of power used when unit is off if switch is not mechanical?

Accepted Answer

When on, It uses 2 amps.  I'm measuring 0.5 when off.  Which is bad news in my opinion.  Compared to my harborfreight 2kw which only uses 1.2A when on and 0.5 when off.
