So convenient with just enough power

I love this little vacuum. I can whip around the main floor, picking up a days worth of dog hair and dust in minutes. It has enough oomph to tackle the rug in the living room for in between clean ups, and does a great job on my textured rugs by the door, in fact I think it works better than our Dyson.  The only downsides are the relatively short charge, about 15-20 minutes, and the small cup. As long as I remember to charge the battery when I'm done its more than enough time, and I keep an eye on the cup. I still use my canister vacuum for deeper cleans and all the attachments for reaching nooks and crannies, but it's nice to be able to whip around quickly with this one anytime.  Minus one star for battery life and not being able to charge the battery in place.

Great power, easy install and fairly simple setup if you are familiar with setting up wireless networks.  I plan on buying at least a couple more in the near future to bridge a much longer distance.

SO convenient in our older S10, which only has a cassette player.
Have been using this dual socket a couple yrs.
It's been the perfect solution to power a Garmin and Sony C.D. player at the same time.

Haven't had a moments trouble with it. No loose connections, no blown fuses, and not hard on the alternator.
It's a good fit in the cigarette lighter, and devices fit securely.
Red light shows when connected.

Plugs length can be adjusted to fit vehicles outlet. (photo)
Supports up to 15 Amps / 180 watts of electric appliances.

just what you need when you can not carry around an extra battery, so this is the answer! a little heavy, but not a problem.
it charges quickly with the enclosed cord - put them both in a small zip lock bag and put them in my pocketbook. now I don't have to be afraid of running out of power when I am not home.

Arrived on time ... works as intended and maybe more.

One day, I was pondering how best to de-clutter my wall receptacles from a glut of power adapters and also my table from a spaghetti of ensuing power cords used to feed various 9V-12V DC equipment on my table or rack. Fortunately, I chanced upon this little gem and in an instant ... my problem was solved. I chose the 12V adapter with the highest rated power output and used that as my primary 12V DC source and this little gem to power all the other equipment on the table or rack. I also bought another similar unit form another source here on Amazon and used that to supply the 9V DC source to power the rest of the units that needed a 9V source. Everything worked fine and I relegated the remaining adapters to storage. Been working without a problem to this day.

Delivered quickly as promised.  It's the perfect size and power for my needs.  I am no longer tethered at a charging station in the airport hoping that I find an outlet that actually works.  I sit where I want at my leisure, not lined up like cattle in a feeding line.  The extra port allows me to offer another person this freedom and there's plenty of power.

So easy to work.  Power is very good.  No gas.  Love it.

So much power!  I use this with a rPi when travelling as a file share hub at conferences and never have to worry about being near an outlet.

Dependable for necessary power, and fairly easy to use.

Was able to get one of these through Prime and have it arrive the day before Irma came ashore here in Florida. Ran on the first pull and was able to power my LG fridge/freezer, 2 box fans, phone/Ipad chargers, and a baby-bottle warmer at once. Ordered a wattage meter to keep an eye on my usage, but it didn't arrive in time. I like the PowerSmart technology that allows me to only use what my devices and appliances require. The car charger with the 2 USB ports is a nice touch so you don't have to sit in the car and waste gas to charge items. It does run pretty quiet and comes with everything you need to get started right out of the box (minus gas). This item made going without power for 2 days doable for my wife, 2 children, and myself doable. Lastly, the little trays to catch oil overflow beneath the side panel and gas up top are nice for clean-up. One negative is you can't tell how much oil or gas you have, so overflow is a possibility if you're not bone dry. Price was not bad either. Would definitely buy again or recommend to someone in need!

This thing is pretty handy, and the 7~24V input means that I can power it from just about any DC circuit that I ever end up with.

Super convenient way to deliver power (both 110V outlets, as well as the high power USB ports) when and where you need it!

I love that I don't have to look for an outlet to charge my phone when traveling. Also have already had a couple of power outages in our area and it was nice to still be able to power my devices.

So happy to know I'll be able to have power during emergencies or just plain running low on phone power while I'm out.  Works extremely well.

I really like the size and the convenience of it.  The small size fits perfectly in my bag and the switch to a wall plug is a huge plus for me.  I'm always carrying a back up portable battery and wall plug in case one dies but this makes it easier bc I only need one device now.  So happy!

this is so useful.  i can plug in multiple devices and they charge at the max rate.  it greatly reduces clutter.  this is the 40w, but the 25w may be sufficient (and cheaper) for most folks
