I travel a lot and have to use my laptop at various stops. It has built in WiFi provided by job but battery was running low. So of these with the outlet wouldn’t even charge my laptop. This does perfectly while I also charge my phone. It can fit into a cupholder too but I keep to the side.

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) drill charger camping bed pump (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!

A bit bulky and has a short wire but works just fine and performs good. It is also not too loud.

I used this when I went camping to blow up my air mattresses! It was a life saver, as the campsite we rented had no electrical! I used the car lighter attachment (it also comes with connections to hook straight to the battery) and it was very simple to hook up. I was worried it wouldn't have enough power. It has multiple outlets but I only used one at a time!

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!

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)
