Had this unit for over a year in a car for charging work laptop. Sold the car, moved this unit to new truck. Probably over 200 hours of use charging laptop and still works like new.

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!

Update 8/12/2024. Been using this two or three days a week since purchase, about eight months. It's been very reliable. I have this hard wired in with 8 gauge cable with a 40 amp fuse in the positive side. (ALWAYS go big on inverter cable). I use this primarily to run a 150 watt hot logic warmer in my car. Runs about two hours at a time. It's been used for some other items too, primarily work lights. Very pleased and well worth the money I spent. Highly recommend. (Original review) 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.

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.

Update 5/4/2019 --- These have been working great as a silent power supply for my laptop and other equipment on solar, but I ran into a problem with my latest purchase. I have had 6 of these, and two have died through years of use. However, the latest one, which I had on hand as a spare, works fine at night, but during the day it cuts off constantly. Why? Over-voltage. It has a maximum operating voltage of 13.8 volts. And yes, I am running it over voltage. Sometimes, the solar will spike to 14.5, or on partially cloudy days, 14.9. This never bothered the older versions, but the new one shuts off anytime it goes over 13.8. In fact, I had never noticed the 13.8 volt spec before. I just assumed it could handle the normal output of a solar system or a car alternator, which can be up to about 15 volts. That is a serious DESIGN OVERSIGHT. This seems to affect only the newest models, which must have slightly different components. (Including a much brighter status LED which is actually quite blinding. Nothing tape can't fix.) Also, when this cuts out on high voltage, there is no indication. The Status LED stays solid green, but the power blinks off for a few seconds, up to a minute, or until voltage drops back below 13.8, then back on. I live off-grid with a small solar system. I have two 400-watt inverters running on independent systems, but I rarely need more that about 45 to 60 watts on each. Running the 400-watt inverters is fine, but they make a lot of noise, with fans that run almost continuously. I decided that I had enough, and bought this 100-watt inverter, because it is specifically mentioned in the reviews that it does not have a fan. Since I could not find any standard inverters that specifically mentioned not having a fan, I had to go with this one that has a cigarette-lighter plug. I used the NOCO-GC018 (link below) cable, which features a female plug adapter, an inline fuse and eyelet terminals to connect it to the posts on one of my 400-watt inverters. NOCO GC018 12V Plug Socket with Eyelet Terminal It works great. Now I can shut off my large inverter with the annoying fan when my power needs are small, and enjoy the silence of this inverter. This greatly improves my sanity, as the inverters are only 5 feet away from my work area. The ony issue I have with this inverter is that there is no power switch, meaning that you have to unplug it to shut it off. Eventually, that may cause damage to the connector. In my setup, I simply wired a switch into the positive side of the NOCO cable, so that I can turn it off without unplugging it.

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.
