Whistler Pro-800W 800 Watt Power Inverter

A prime selling point is the internal technology it's designed to handle high startup loads for longer than most inverters. Note that a common load nowadays laptops and electronic equipment (which use their own transverters) have a high capacitive load. Power tools usually an inductive load. So you need an inverter that won't trip out while most modern (i.e. non resistive) loads start.

For my wife's van 3 laptops and a Wii is common. For my truck for various power tools. My trusty 400W would no longer reliably handle the load. Esp at startup without a plug which in first dance.

Don't look for cigarette lighter adapter it just won't work for 800W. They're common with 400W inverters but won't reliably supply them either (12-14v x 15 Amps is about 200 watts). And even your cigarette lighter wire is usually undersized (read not for continuous use at fused amperage) So don't ding any high power inverter over cigarette lighter adapters it's a simple technical requirement.

To handle the load, I'm running new fused power wires from the battery through the firewall to the dash.

Note one trick on running wire run two 10 gauge wires instead of one large one for each polarity. Just be sure each red/positive is individually fused at the battery and the you can tie them together at the inverter (each wire is self protected safe and both together supply needed current). This is a common trick used by HAMs and others. Much easier wire to work with and fuses (up to 40A) are standard automotive fuses and holders.

Here's a link to that wiring trick (or search for "most practical powerpole size for 700 watt inverter")

I use this power inverter to power a laptop, webcam, and video camera while storm chasing. The only problem I have is the USB slot. It will not keep up with a smart phone, at least with everything powered up and charging. I fixed that issue by adding a small extension cord.

Really this inverter works pretty good. Keep in mind you're getting what you pay for. If it's cheap, don't have overly high expectations for a product to last 20 years. Mine is used and abused as it sits in the floor of my car. Passengers kick and step on it all the time and it continues to function.

All in all I thinks it's worth the purchase.....

I HAVE USED IT ONLY A FEW TIMES BUT IT FUNCTIONED PERFECTLY. I'M RUNNING THREE SMALL AC FANS ON MY PONTOON BOAT AS A TEST FOR BEING ON THE WATER THIS SUMMER. SO FAR, SO GOOD AND RAN ALL THREE FANS FOR ALMOST 8 HOURS ON TWO 12 VOLT DEEP CYCLE BATTERIES.

Our float was awesome with the added lights powered by this inverter.

Thanks for the deal. Good stuff with no worries.

I have tested our CPAP machines (2) with a portable battery and it works great. Haven't tested how long the battery will last. Product looks good with battery connectors and built in fan.
