Customer Ratings & Reviews

Plenty of juice to run about anything you could need in the car. I even ran an electric heating pad for my daughter when her stomach was hurting. I use mainly to charge drill batteries, faster phone charging and charge my laptop on the go. If I needed to I could even bring along my printer if I needed to print documents on the go.

This little inverter does the trick when using air mattress pumps and keeping things cold in the lil fridge. I recommend this product for compact trucks and cars. This is also priced right for the value.

Very powerful, very easy to install, don't leave plugged in or it'll kill it battery.

This has been really helpful for me to keep my laptop charged and run other devices in my truck. Do not use it much, but it stays in the truck and so far, does the job when needed. Power is a little low, but the low price relative to higher power models, does put it in a sweet spot. I initially thought I would have to return it as it kept cutting out and beeping like crazy. This device is not happy when power fails and devices are connected. There were two operator errors! First ensure the 12v plug is fully seated and not at risk of being bumped / momentarily disconnected. Second, you may need to disable your auto engine cut off as when the engine restarts, it will drop power to the inverter.

This power inverter delivered everything I was looking for. It was very easy to connect to necessary power sources to make it operational. We had power outage for 3 days recently and we were able to keep our iPhones and laptop computer charged. I would highly recommend this inverter. Easy to use and plan on taking it with us on trips camping.

Fits underneath the shifter console of the Prius. Relatively quiet. Wish it had three outlets and more available power. It was all I could afford. Boondocking/car camping.

Solid 3 1 problem I have is it beeps a lot if it’s overloaded or something you have to unplug and plug it in to stop. 2, when it’s under load it sometimes makes a bad smell. 3. It gets the devices charged

The charger is very good. Sadly the cord that connects to the cars 12v compartment is too small it needs to be extended longer

Love this little device. We had it hooked up to our cigarette lighter to run an inflatable for a trunk or treat gig we did. Worked marvelously

Works great! Great price too! My wife uses it with a curling iron on trips. We also use it to power our laptop while traveling.

I bought one, tried it on two cars with the cigarette plug and returned it because I thought it was dead on arrival. Best Buy exchanged it for another one, no questions asked. I had the same problem with the second one...then I found these reviews! Once I fabricated a new cigarette plug it worked great. Very handy for keeping devices charged during car camping. Only other problem I have is that the design is rather chunky with mostly empty space inside- this really limits your mounting options. The design could be made much slimmer if the body was metal and functioned as a proper heat sink - the current design looks like a metal heat sink, but is just silver painted plastic.

I travel, I have been looking for one of these for quite some time. Went to Best Buy found it. I haven’t had a problem. I’m glad I have it. It can be used for anything. That fits the wattage. I like that small wattage more items. I’m thankful for this purchase.

So far so good. Used the product to change a laptop computer and it worked perfectly fine. The fan kicked in to keep the unit from overheating.

[Employee of bestbuy] This product has very nice quality and performance. When comparing other brands, this product has the best performance for the its size. The remote turn on is a great touch as well, I can’t wait to try that feature.

Very great and reliable product. Been using for the past 4 years

I’m always on the road. This keeps my laptop fully charged all day long. Great product.

[Employee of bestbuy] Excellent 500w power supply. However, if you plan on using the full 500w then you will need to be connected directly to the battery. For this I would recommend that you get this installed somewhat permanently through Geek Squad AutoTechs. The unit can still be remkved, somewhat, easily with the thumb screws that secure the wires in and probably after removing whatever screws might be holding it down. The unit itself comes with 2 different types of wiring. One is a cigarette / power outlet plug that is good for a maximum of 150w. The other is a short battery clamp style to use directly with the battery. This really only allows usage near your battery location.

It’s working great, I’ve pulled all 500 Watts out of it for over an hour and it works. It’s noticeably less money than similar ones, from an established brand and I’m very happy with it.

for the price this was perfect and a life saver and it comes with cigerette lighter connector too
