whats the difference between the 445u and the 445a
2047337
The "U" represents it is intended as universal- to be spliced into any stereo. The "A" designates it ha the Alpine stereo connection already installed- it simply plugs into an Alpine stereo.

I have the KTP445A, it is plug and play with Alpine head units. The -U is the "Universal" to be used with other head units.
2047339
The A has direct plug-in connectors for select 2005 and newer Alpine head units, the U is equipped with the RCA and Auto-Sensing-Speaker level connectors for universal applications.

The 445a is an alpine only amp the 445u is the universal one, don't make the same mistake I didt and buy the A thinking its universal
2047341
The u is the one you buy if you do not have a alpine head unit and are using factory radio. A is the one you buy if you have a compatible alpine head unit
2047342
Universal versus alpine cables. Choose universal if you don't have an alpine head unit.
2047343
The 445a is for alpine head units only and the 445u is universal for other brands
2047344
the 445 u is the Universal for all types of radiosThe 445a is for Alpine only

The only difference is the plastic. One is dark purple, which looks black, and one is a slightly translucent blue. Both run on the same frequency: 2.3MHz.LW is correct in that the blue ones are the older model.

The "U" and "R" models are the same "Ohio Mom" is correct "U" is primary sold online and "R" is for "Brick-and-Mortar". The only physical difference I have seen is the logo on the router is gold for the "R" version and silver for the "U" version. I have had both versions of the RT-AC66 and could not find anything technically different. There are 2 separate firmware sites on ASUS web site but the version numbers are always the same.

As I understand them, the 4460 lets you add your electricity costs directly into the unit, so that you can see a running display of the unit's cost over a period of time. With the 4400 you would have to write down the kwh values and then do the math yourself.hth..Stephen

The 445 is mainly an amplifier just setup to pair with Alpine equipment. The 445U is a Universal unit that can be installed with any factory or other make of head unit.

I don't know the difference, but we got the cheaper one and only one unit worked. And trying to get it out of the package destroyed the box to the point I didn't even know how to return it. Don't recommend.

What the difference is, I do not know. I have the 511AX and I am extremely pleased with it.

Hi Giacomo, It's the 802A model. 802A is a US model while 805A is a Brazil/Latin America model. -Anthony

From my research, the 4660 calculates your power consumption in dollars and cents, hourly, Daily, monthly and yearly. It also has a batery backup so that if the outlet loses power it remembers the data and continues reading when it is powered back on.The 4400 displays usage in Killowatt hours, so with the info, your electrical bill and a calculator you can figure out the cost, assuming you can do math. Now there are 3 kinds of people in the world. Those who can do math and those who can't. Since I am in the latter category, I just purchased the 4460. Worth the extra $15 IMHO.

I don't believe there are any differences besides the clock speed. Everything seems identical (same chipset, RAM size/speed, disk model, wireless model, etc) and the only difference the i7-4510u has is an increased clock multiplier. I can say that 1.8 GHz base clock has proven more than enough for anything I need from this computer (read: educational Solidworks, light games/transcoding, productivity, 50+ tabs), and combined with the ssd and ample RAM, I doubt the difference would be significant unless you had heavy single-threaded workloads. It seems that this model has been marked down more because people rarely look at the clock speeds, and this is the cheapest i7 model (also the cheapest with 8GB RAM and 256GB SSD, my constraints); the market for the other one would be more professional.

There appears to be no difference in their specs. They are listed together. I suggest you call them directly. Sorry I could be so little help

I don't know the difference between regular one and ultra. I am also not sure about the warranty one used items

Ah... it's a good question. Somehow, the cord of FPA80UW is very short as you questioned. FPA80UW is an upper model than FPA40UW, but the cord of FPA80UW is shorter than FPA40UW. Why?

There's only one notable difference. The 5875 came with a 3 year limited warranty, while the 6244 comes with a 5 year limited warranty. The other "difference" is that the sales documentation for the 6244 points out the "capability of being installed within 18 inches of a building". However this is no different than the 5875 when you look at the installation documentation. (Those tricky sales people.)

As near as I can tell, the biggest difference is the model number. Lasko has been making this heater in the same basic design for at least 10 years. The 5919 and 5905 have basically the same geometry and rating. Both have two "power" settings and their sizes are the same. The differences appear, to me, to be only cosmetic. I will say that my 5905 models have a more powerful fan than the model I first bought 10 years or so ago...a very welcome upgrade.

It is basically the same, but the One is a better, improved product. I understand they do not make the Ultra anymore. The Ultra is not as accurate as The One

I called Lasko tech support with a similar question. The 4443 is taller, and generates 304 CFM airflow at 82 watts on the highest setting. The HVB 4930 generates 354 CFM airflow at 105 watts on the highest setting. Lasko does not provide information on sound levels of their fans. The Lasko HVB 4924 and HVB u35100 models have the same airflow and power consumption as the HVB 4930. The HVB u35100 is not sold at amazon, but at S*ms Cl*b.The HVB 4930 can generate higher air flow; but for energy efficiency, the 4443 produces more CFMs per watt. On its highest setting, the 4443 consumes 82 watts while the HVB 4930 consumes 81 watts on its lowest setting; based on data from the manufacturer.
