Xantrex 400 Watt Inverter
I received the Xantrex Technologies 851-0400 APower Plus 400-Watt Inverter unit on time. It has been working great. A great unit for the price.
Beware of the 60 +/-4 Hz frequency specification
Several of the Xantrex inverters including this one have much looser frequency specs compared to the last generation of inverters which were typically 60 Hz +/- 0.01%. Many of the current crop of these inverters have 60 +/-4 Hz which is 60 Hz +/- 7%. To be fair, I've noticed a number of inverters made by other companies also have relaxed this spec. I measured the output frequency of several models and found their outputs to range from 58 Hz to 64 Hz. I didn't test to see if the frequency changed with temperature, input voltage, load, or other other factors. I suppose the reason for this change in specs is that these manufacturers are now cost cutting to the extent of eliminating a 30 cent quartz crystal. The frequency variation is most ... Read More
Great product
HAve no problems with this, 2 outlets comes in handy when someone MUST charge their phone while you are using power for something else.
Like screaming kids
Purchased unit with intend of running a portable DVD player for the kids, and a peaceful trip for me. Instead I got the opposite, as soon as I plugged the unit into Power Port I blew two 20 AMP fuses (on 2004 F-150) so I did the dumbest thing I wired it to the battery and short the battery out. So I'm out a battery and inverter at this point. Take my warning DO NOT BUY this piece of junk, you'll feel better giving a homeless person $32.19 instead of dealing with disappointed kids.
So far so good
So far so good. Bought it to use in our camper on a 9 inch TV that has a TV box hooked up to it. Doesn't make noise, takes up minimal space and the picture is great. We haven't had the occasion to hook two things in to it yet but so far so good. Working as it should. Thanks
