Cobra CPI 475 400 Watt Power Inverter Review

Average Reviews:

(More customer reviews)We needed a higher power interter to use in our RV when camping without shore power.We needed to power two laptop computers, charge cell phones and PDAs and run a small fan.This Cobra unit reviewed well so I ordered one from Amazon.It was delivered in just a few days (thanks Amazon). It has a solid feel to it, connectors are of good quality, and it is small enough not to be obtrusive in the confines of an RV.I used the cigarette lighter plug and put this on our dining table.The two AC plugs accommodated two AC adapters for laptops.As a bonus, there is a USB port on the Cobra that will supply 5 volts! So, I can charge my Blackberry simultaneously.What a delight!!The unit has an internal fan which only runs as needed.If I'm just charging a cell phone, then the fan does not run - but when I've got a load on - the fan runs and effectively cools the inverter.This is not a pure sine wave inverter but I've had no trouble at all using it with various laptops, pdas, fans, and cell phone chargers.I've not used it to power a TV or Radio (those could be more sensitive to interter noise).After a months use, I'm delighted with the inverter - it meets my needs completely.

Xantrex Technologies 813-0081-00 XPower Pocket Mobile Power Source 100-Watt Inverter Review

Average Reviews:

(More customer reviews)This is a slick, useful product that does just what it says it will do.I used to work at Radioshack, and we sold a lot of these, and they were hardly ever returned, so I got one for myself.I use it to charge my cellphone (with the house charger) and my laptop while I'm traveling.It is much more quiet than other inverters, has a big, blue indicator light to show when it is working, and is slim enough to slip under a seat, or even between the center console and a seat (where I have mine).It says "100 watts", but that is only the peak output.Continuous output is only 80 watts, so be sure to check that what you are using it for is 80 or less.It is great for battery charging, but don't even think of running a vacuum or a power tool, that isn't what it is intended for.

Black & Decker 200-Watt Inverter VEC1045BD Review

Average Reviews:

(More customer reviews)I needed an inverter to charge my laptop and cell phone in the car on road trips, and this one fit the bill nicely.I have tested it out in the car with my computer plugged in, and it works fine.It powered my computer and supplied plenty of current to charge the battery while I was using it.
This thing is smart.If you try to run it off the 12V accessory outlet in your car without running the engine, the inverter lets out a constant beep telling you that you're going to run down your battery if you continue.According to the manual, this beep could also mean that the voltage dropped below 11.0V.I didn't know which it was in my particular case, but as soon as I started the engine, the squeal stopped and it was happy to charge my computer.
The ground fault interruptor, overpower and underpower warnings, battery drain warnings, auto shut-off, the 12V DC pass-through, and the option to hook the inverter directly to your battery are all very very useful features on a solid product.Well worth the reasonable price you pay!

A word of warning: if you need an inverter, make SURE you look at the amperage needed to power whatever it is you want to plug in!This one supplies 1.74 amps, which is more than enough for most laptops, game consoles, cell phones, and portable TVs, but ALWAYS double check and make sure.If you want to plug in a small fridge, for example, check the power requirements to make sure this thing can supply enough current!You'll save yourself a lot of frustration if you are certain of what you are buying.

I highly recommend this inverter!It's worth every penny, and it feels and performs like a much more expensive unit.

Xantrex Technologies 851-0400 XPower Plus 400-Watt Inverter Review

Average Reviews:

(More customer reviews)This item works as advertised, but it is a modified sine wave inverter.If you are planning on using it to charge cordless tool batteries---don't.The owners manual contains a caution about using with cordless tool chargers (such as Dewalt).Do a quick Internet search on "cordless tools" and "modified sine wave inverter" to confirm whether your tool is effected.Some other items that may not work well are appliances with clocks, microwaves, etc.Be sure you understand the limitations of a modified sine wave inverter.
For those smaller appliances that will run on modified sine wave, this item works well.

Cobra CPI 2575 2500 Watt 12 Volt DC to 120 Volt AC Power Inverter Review

Average Reviews:

(More customer reviews)I just opened the package and haven't used this thing yet - so I can't comment on functionality - but I wanted to let others know that this unit DOES come with a cigarette lighter plug (as well as a set of alligator clips) that you can attach to the screw posts.

I wasted a couple bucks on a separate cigarette lighter plug when I ordered because the product information says nothing about coming with the cigarette lighter plug.

Oh - There is also a sticker on the cigarette lighter cable warning not to draw more than 150 watts when using it plugged into a lighter socket (use the alligator clips or your own custom wires to connect straight to the battery for full power)

CyberPower CPS150BI AC Mobile Power Inverter/Converter, 12VDC to 120VAC, 150W, Bottle Mount Review

Average Reviews:

(More customer reviews)I purchased this product with the intention of using it for charging my laptop while on the road. According to the product's spec sheet, it is rated to supply 140-watts of continuous power (and 150-watts peak) and it is marketed as being a suitable power supply for laptops. Unfortunately, when I plugged my laptop (which uses a 90-watt charger) in to the unit it would overload and trip the surge protection after a few seconds.I was thoroughly unamused.

Additionally, I found this nugget from a review on Newegg:
"The problem with this unit is that neither the hot or the neutral plug on the unit are referenced to ground. In other words, the neutral actually has a potential of 60v above ground. This can lead to some shocking situations. The ground leg of the inverter is just a dummy hole -- there is no actual ground.

In layman's terms, the electrical design of this unit is very poor and would never achieve household electrical standards. I can't figure out how they are allowed to manufacture and sell this unit especially when they advertise it for use with laptops."

And upon further inspection, I can confirm that this is accurate, which could possibly be the reason why my laptop charger overloads the unit despite the fact that the unit is supposed to be able to supply 140-watts continuously.

This unit does seem to work well for small electronic devices, but I cannot recommend this unit for any electrical device that draws much power or uses a 3-prong connector.
