- Julian F.Small yet impressivePower inverter very reasonably priced. Delivered on time and packaged well.
I used this inverter along with a DIY backup battery system To aid in supplying backup power to my fiber optic Internet modem and Wi-Fi router anytime we lose grid power. After monitoring and experimenting with my little DIY power backup system, I am happy to say that the system appears to work flawlessly. I probably could have gone with a smaller wattage inverter but I wanted something that I could use elsewhere in case my idea did not work properly. Besides, the cost of this 300 watt inverter was extremely reasonable. The inverter is working great and I am expecting to use it for years to come. I highly recommend this little inverter to anyone who wishes to both experiment and rely upon a useful piece of equipment. - N. SandersGreat power inverter for mobile workersGreat power inverter. Works just as described and like previous buyers stated. I like the fact that it is small and easy to travel with.
- Ramón López MartínezCar Power InverterThis inverter is amazing. You can convert your car’s power to 110V in a second and charge your laptop and phone at the same time thanks to its USB-C and QC3.0 ports. I feel at ease knowing it has protection against overload, short circuit and overheating. Plus it’s super easy to install. I recommend it to anyone who travels a lot, works outdoors and needs to charge multiple devices without issues.
- dukeGood but needs a clamp option at this wattageGood product, I have several of Bestek's pure sine inverters and have been very happy with them, so buying this was a no brainer. Right now I'm using it to maintain a car battery from another battery (I know, long irrelevant story) and it works well. The fan is pretty quiet and I had to check to make sure it was actually working in a semi-noisy environment.
One gripe I have about this is it doesn't come with a clamp option which doesn't make much sense for an inverter of this size. If you're using this in a car you might not be able to push it much beyond 150w current draw because many cars have a 15A or 20A fuse for that. 155w at 12v is ~13A, 215w is ~18A. And I don't think it's a great idea to push those fuses to their rated capacity, especially since you'll have to account for a small amount of overhead in the inverter itself. Using it with a clamp to 12v socket adaptor, everything gets hotter than I'm comfortable with when pushing it closer to 180w and it was shutting off around 240w. I cut the plug off and put some clamps on, works perfectly. But this is strange to me because I feel like many people wouldn't think twice about it. - Joe JacksonCompact and Works.Initial reaction. It is nice and compact. I plugged it in and tested it in the car and it seems to work fine. I will be using this when I am on the road between appointments in my car. Often, there isn't enough battery in my laptop to continue working. While it is a bit of a pain in the car, this should work fine.
- jshorty84All in One Device: Value, Consumption, Great VoltageI finally judgement day has come for this power supply car charging device! And I must say it has surpassed my expectations. The night I made the purchased man did I look at a lot of products and read a lot of reviews. There was a lot of mix feelings and I had narrowed it down to this product and another brand. I decided to take a chance with this one as it was about a couple of bucks less. And I am so glad I took the chance. Not only did I get a good bang for my buck. This sucker has endure a couple of water spills! The value of the product is definitely worth it even though I can't afford to dish out. Lol totally worth it for how I have abused it. ???? So durability checks out great. The power consumption is amazing. I have been able to keep my laptop alive. Not able to charge the battery but at least I can turn it on to use it and do what I need to do quickly. And I can use my super charger for my phone and I love how it has two wall outlets and two USB connections.
- Mike GonzalezGreat product for Camping!Worked great for pumping my full size mattress for my camping tent. Totally recommend it. it did not short out any fuses on my car, I also had the car running and not just on battery mode. Had a Nissan Rogue rental.
- Mark in TexasUseful and reliableI've had this inverter for over 9 years now, taken it on multiple cross country trips, including ones that have involved car camping where this was our only source of 110 AC power for days at a time. I originally bought it after such a trip where we found the 1 amp USB slots that were factory-installed in our SUV didn't put out enough juice to recharge my wife's iPad while she used it, or even get it to a full charge in a reasonable amount of time when she wasn't using it. Since then this inverter has powered laptops, portable DVD players, iPads, and phones, often all at the same time, while providing steady power and not overheating, thanks to its built-in fan.
I think the few people who have had problems with this are either trying to use it with devices that draw too many amps, and/or their car's electrical system is limited and not designed for such an inverter (see further explanation below. So my advice is:
1. Stick to the devices it (and your car's electrical system) were designed to provide power for, and avoid amp-hungry appliances like power tools and coffee makers I've seen mentioned in the low reviews (SMH).
2. Check the specifications of your car's electrical system and its output from its cigarette lighter outlets before you buy this inverter, and before you jump to blaming this inverter when things go wrong.
Car cigarette lighters are practically never designed to be on a circuit all by themselves, and depending on the car model the cigarette lighter could be on the same circuit only with low-draw components like dashboard lights and overhead interior lights (many of which would not necessarily even draw current at the same time that often), or it could be on the same circuit as a high-draw component like, say, your car's air conditioning system. That is going to make a big difference as to how much additional load that circuit your cigarette lighter is able to handle, and thus will affect what you can plug into the inverter.
I personally have used this in a 2011 Toyota Venza, 2011 Chevy Malibu, 2017 Mazda 6, and a rental in 2016 that was either a Chevy Tahoe or GMC Yukon, and again, never had any issues in any of these cars, but other vehicles (including newer generations of these same models) may have the issues I mentioned above.
