5 out of 5 eggsNot for those lacking experience but requires smart hook up

Pros: Like the 200 watt model the 400 watt model requires brain power to hook up to a 12 volt marine or car battery. Not for those lacking experience, obviously! ! ! But as a pro, I prefer B & D over others because of the warranty and flexibility of this product. It's price is good too. Just don't get your wires crossed, like always, and you'll be a pro inverter user too! ! !

Cons: Not for those lacking experience! ! !

Other Thoughts: I'm getting off the grid, one room of my house at a time, using marine batteries, my car alternator, and solar power.

1 out of 5 eggsCannot recommend (technical)

Pros: 2 AC outlets, USB port for charging devices

Cons: Just by looking:
Exposed high-power contacts in rear

Through testing:
Failed to power a 60W laptop
Failed to power a 75W light bulb
The fan is LOUD. This is expected at this fan size, and the fan does slow down (and get quieter) if there is nothing attached. This is the only way I could the inverter to run for more than a second.

Directly from instruction booklet:
* Use battery clips ONLY
* DO NOT use the DC accessory plug or the fuse will open"

The instructions also repeatedly mentions "buzzing" sounds, snowy pictures on TVs, and TV and radio "interference". This is actually a result of the modified sine wave, as described in the instruction manual. The instructions blame the attached device's power system, despite the fact that better power inverters do not have this problem. This is not because of the modified sine wave power system so much as the extent to which it is modified. For more information, search for "Pulse Width Modulation", specifically the switching frequency.

Other Thoughts: This might actually be a good power inverter for your needs, but only if you are trying to power household items from a car battery, not through an actual car. Alternatively, you may power devices that take less power than a light bulb, like a phone or tablet. In that case, get a USB adapter instead. That's the only type of device I could think of charging from this.
