To calculate watts for AC: watts= pf x voltage x amps
Pf for resistive loads 1: this would be a simple motor
Pf for inductive loads average .8 mostly electronic loads or inductive motors.
So far so good. I got this, ran out to my truck, plugged it into the 12v outlet and hooked up my Coleman mattress air pump. Turned it on and away it went. It is not overly large at 6 inches long a little over 4 inches wide and 1.5 inches tall.
Comes with battery clips that have a 22 inch cord and a 12v outlet plug that is 24 in long. It has 4 USB outlets which 3 are 2.4 amps and 1 is 1 amp.
I will update after a few months of use.
Update: 10/21/15 I have used this about 20 times now. At least 10 of those were out on the boat when I needed to air up and down the tow-able tube. This is such a nice setup. I got a cheap little bag to keep everything in. I have also used it for running a stereo off of my diesel truck batteries while out camping. Used it for a running a small air compressor and to run some lights to fix our 4 wheeler out in the dark while out camping and few other things. I am still highly impressed with this little power packed device.
Still works great. I do keep it ina little bag. This thing always rides in my truck now unless it's boating season. Then it still gets used out on the boat.
I admittedly had never heard of bestek before, but i must say i am pleasantly surprised at the build quality. Even more so when considering the price. A whole lot of features all in a well thought out design.
First of, while pretty much self explanatory, the instructions are well written in easy to understand english.
2 modes of powering this, either through the included jumper style clamps direct to the battery, or via the cigarette/accessory plug from your vehicle.
2 ac 120 plugs, to run things that you would in your home.
and 4 usb ports, 2 at a steady 2.4 a one that is auto for devices that don't include their own safeguards (most modern things will like phones and tablets) senses the proper charge amperage and delivers only that up to 2.4 a and a 1 Amp for low consumption devices.
400 watts is your operational wattage (500 watts max, but you should shoot to stay close to 400) but just as important is the peak wattage or the start up wattage. This is always much higher to basically get something started up, before it drops down to its operational wattage. This unit features 1000 start up watts, which is much more than most inverters in this price range. That will allow for a lot more things that this can safely run that may use low running watts but a high amount of starting watts.
To further clarify in a very simplistic form, however not an actual example. Say you are running a fan. when you turn the fan on, lets say to go from a dead stop to the high speed setting, it may take 700 watts (again random numbers to illustrate a point) however once its up to speed, it may only need 300 watts to maintain that speed. leaving 100 running watts still available for other uses.
The design of this unit is well thought out with the different inputs and outputs positioned in such a way that even if every port has something plugged in, nothing should be tangled or interfering with each other.
Also the black base feature mounting tabs if you wanted to mount this in your vehicle for a more permanent solution. If doing that, this also features a grounding screw, that can be attached to any main part of your vehicles metal body or any other grounding source. While not required, never hurts,
I am not really a camper, however, i always seem to randomly come up with uses for an inverter that while not necessary would simplify my life just a little. Plugging in the vacuum to clean the cars out. or tailgating with a mini fridge, charging that back up battery jumper etc.
I would and have recommended this in a heartbeat. and look forward to seeing more products from this company that has so for been very impressive in quality.
This was provided to me to sample and write an honest review. MY ratings never remotely consider that factor, I rely to much on reviews from time to time when buying products to give something a positive rating because its free. However I do consider the list price on amazon for some items to keep it all in context. For instance, you shouldn't expect a BMW for the price of a Chevy.
If this review helped you , please click on the little link below, so i know i am hitting the things you need to know and that my reviews are helping people. Thanks
However I gave it three stars as I feel these are important points.
Two issues- this is described as "ultra silent cooling fan " Though It's not loud, it is definitely not silent. I could easily hear it above the car noise, in fact I thought at first the sound was from the car ventilation. And the fan came on just using the USB ports, very little power draw, I could understand it if came on with a real power load, even 10 watts on AC, but we're talking charging a phone.
All plastic construction- seems OK, but not sure how well it will hold up stored in a car.
