    Junk. Powers itself on and off and surges
    Bought to run electronics in truck while on construction sites. Worked a few days the started to turn itself on and off. Stopped doing that then all of a sudden decided to send power surge while my laptop was connected frying components in it. I apparently missed return date by 2 days so was told not there problem I’m busy in life and missed the date. I guess I will go back to my old inverter that I have had for 10 years just is a little louder after all the years but it works and don’t fry my laptop. I don’t know if I just got a bad one or not but think a replacement would not of been asking to much over a 2 day issue, and never once complained about my laptop to them because it was under warranty and that company actually takes care of their customers.

    ive purchased a few other brands but found the fan just to dang loud. i dont mind a fan but when its a constant full speed and sounds like a buzz saw in the car its just too much. anyways i found this one and liked it was fan less ive tried it out with my surface pro (65w) and it works great! i have a wattage meter and tried it with other devices like a
    cpap (30w)
    1.5 cubic foot mini fridge (25w to 35w)
    drill charger
    camping bed punp (50w to 75w)
    32in tv (60w)
    nintendo switch (7w)

    this device is compatible with most laptop since most standard laptops are 35w 45w 65w and 90w. anything above that like a gaming laptop (150w to 300w) you will have to turn off the computer and charge the battery. you can find out your computer wattage by looking at your power brick to check the rating. you can also run the gaming computer if its in eco or low power mode as long as it stays under 100w. (mine was 65w in eco mode and its 250w max)

    Over all it works great its compact for travel and i recommend it!

    I bought this in 2015 and have used it--continuously--in a few different cars since that time. For the past several years, I've used it in a Chrysler Town and Country minivan. I keep it plugged into a cigarette lighter socket, and I have a USB extender plugged into the AC port on this inverter. I plug phone chargers into the USB extender. I have occasionally used the AC outlet to charge/use a Thinkpad laptop. This Energizer inverter has worked flawlessly for 8 years, and seems to still be going strong.

    Seems hard to go wrong with any Energizer product. First thing I noticed was it weighs more than the old inverter its replacing. That to me implies quality. I also noticed this has a metal, probably aluminum, case. Should help with heat dissipation. On / off switch feels solid too. Overall build and fit seem very good. At this time I'm pretty happy with it.

    The EN100 works great! I use it to SILENTLY charge a Stanley fatmax via an extension cord from the 110v outlet. Also charges a 7in tablet and a Nexus 6 smartphone from the two USB ports.
    The fanless design is the main reason I purchased it. Replaced a 120w that was making a horrible noise from the dying fan. With the EN100 I don't have to worry about fan noise. Plus that's one less moving part to break.
    Got it next day with Amazon prime! Shipping Packaging was good, but needed scissors to open the final plastic package.

    Things to keep in mind:
    If you pull 100w continuously it will get hot, and it has no fan, so use this out in the open where it has airflow.
    2.1 amps is the max combined current for the USB ports, I would have liked 2.1 amps each.
    Left USB port will charge faster, I believe at 2.1 amps. Right port seems to only charge at 1 amp even when the left is empty.
    There is an occasional quiet high pitched "switching" noise when drawing a lot of power from USB ports.
    The plug can tilt 45 degress up or down, a total of 90 deg from one extreme to the other.
    The plug is short, the inverter is wide. By that I mean it won't fit in 12v outlets that are recessed or right next to other things on the dash. I'd recommend a 12v extension cord or splitter (be careful with splitters, you can overload your 12v outlet and blow a fuse if you pull too much power)

    Sounds like a Western movie. Worked for a 45 days then died. Instead of designing this product with user replaceable fuses, the fuse is soldered to the internal board. The product is under warranty and I did get an RMA to return it postage paid to PowerBright for repair. PB still may declare operator error then demand payment for repairs. I will find out. Cheaply built to not have a swappable fuse. Profit before quality in this case means customer carries the risk with simply operating the inverter. Specs states it has "Smart Chip Protection" with an image of a chip. Specs also say "Thermo Operated Fan", with an image of a fuse. Fuse immediately blew on a 32F day when plugging in a cord. Specs state all sorts of electrical protection. Blowing a soldered glass fuse is not what a reasonable person would call a protected product. It's the difference in having an inverter available after fuse swap and being without an inverter. In my case, I'm without an inverter and had to buy another as I wait for RMA repair. Products that do not last is trending and we have all subscribed!

    love this little unit...charges my iphone and runs my boombox w/dock at the same time without a peep...no problem. Nice tilt to it, too. This is the second of these little units I have bought. I liked the first one so much I turned around and ordered another immediately. I use it to supply 120 volt power to a CD/iPod/iPhone docked AM/FM unit with beautiful sound...I can stream Pandora (as an example) and charge my phone at the same time with this 100 watt unit. Love it. Came quick, well packaged and super cheap. This is my third unit...all work wonderfully, but are in various buildings. Our place is all 12 volt, solar powered. We have a screened summer house, a straw bale cabin, a studio for my wife, and my office/shop. Not to forget the house (although I have a large inverter in the house) Did I mention that they are totally quiet...I now have four of these units.

    Hello Buyers I would like To give you a warning before buying this inverter. I just received it and open it up so see what fuse’s I would need to Buy to replace if they ever Burned out. Upon Opening and seeing the fuses they where soldered straight to the bord there for if the device Blows the 2 25Amp fuse’s it would render the product Completely useless. If your buying this product for a temporary inverter i would recommend this. But due to the fuse situation its a one time use product. But that aside it is a nice inverter.
