I ordered the LESHP brand 400w instead and it works as expected.

It progressively gets louder and faster as the voltage drops more

As far as the build quality goes its pretty good, the device is very light but strong

The fit and finish/ build quality is surprisingly good considering the price point

Works as described, took on camping trip used it off a marine battery

Works as described.

This is a high quality product and works as described.

Don’t waste your money!!!

It progressively gets louder and faster as the voltage drops more

It has good power output and the cigarette lighter adapter is super handy

Most important you can safe a life.

It also came with easy directions to put the wires and cables on for easy use

Makes its convenient use... USELESS!

Especially inside a moving RV on the wonderfully well used roads in this country!

This was purchased as a gift for a friend who is getting great use from it and is extremely happy with it.

I loved this thing then someone broke into my truck and stole it

We had a pending tropical storm and live in an area with many ice storms that cause power outages, so I thought a solar charger would be a good thing to have

It's nice to have a generator, but in evacuation, you are on the move and need some way to charge basic things like a laptop.

Either way that's quite alright because this thing can be so useful when away from home

This thing was a waste of time and caused me to postpone my trip

It's a nice little inverter that powers the LED TV and Bluray player in my motorhome

Saves me the cost of an expensive inverter.

It is a handy, portable inverter which is perfect for us because we travel a lot and sometimes working while on the road and we need the laptop plugged in all the time

The cheap $20 inverter I bought at Home Depot was only 100 watt and inflated my air mattress just fine

I truly think this is one of the best items for a vehicle

Something that would enhance this item would be a bag to carry it in.

With hurricane season upon us this can be a very useful item to have on hand

A couple negative items to be aware; the low voltage alarm is sensitive when swithing power sources

I mainly power my laptop and other items that do not exceed the 750W stated.

Works great! worked great during the hurricane

I installed this in my work truck, no complaints!

so I wonder if this thing blew a fuse or something

No issues with overheating or blowing fuses

Do not use the cigarette lighter to provide inverter power, it will blow the fuse for the lighter
