Beware: Grossly underperforming on amperage - JUNK!
586284
I purchased this item to provide in-house operation of my Dometic CDF-11 12V compressor fridge, which is rated as a 30 watt power draw.  At the rated 13.8 volt output of this power supply, that translates into 2.17 amps.  While the ratings claim 5 amps as a constant output capability for this power supply, when I attempted to operate the fridge from ambient to a set 35 degrees, the power supply overheated and went into protective shutdown in about 30 minutes.  Suspecting that the fridge maker had provided a lowball number, I  wound up rigging up a multimeter to a short 12 volt extension cable I had lying around and monitored draw as the compressor operated.  Though there was a slight transient startup draw of a tad over 3 amps, that was as high as i saw in 30 minutes of monitoring. Constant draw hovered around 2.2 amps while the fridge ran.  And the thing obviously overheated again and went into overload protection, this time after about 33 minutes.  SO - It's rated  for a constant 5 amps, but in an air conditioned house with ambient temps in the mid 70s, it overheats at less than half its rated output!  I  took too long (over 20 days) to get around to applying for a return, and now I get to own an ugly paperweight that purports to be a power supply.  Dear Amazon, please heed customer feedback and stop carrying deceptively labelled JUNK!

Woefully under-powered and cheaply made. Do not buy! Leaving a review to prevent others from making the same purcahsing mistake I made

I bought a GS Mini - which i LOVE. Great quality, great value. Decided to get this pickup to perform or record with. Due to a shipping error by Amazon, I actually got TWO of these by mistake (and am returning both). So I had the opportunity to confirm that it was not a defective product I received - BOTH pickups completely suck.
Good news: easy to install.
Bad news: VERY, VERY LOW GAIN. ESSENTIALLY WORTHLESS. VERY, VERY NOISY as a result. I tried it direct to an amp - UNUSABLE. I tried it through my Fishman Aura pre-amp - slightly better, but VERY noisy and, for me, unusable.

I have owned other acoustic guitars with pickups -  Ovations and a Guild with a nice Fishman pickup (also an unpowered pickup like this one, but which was much more usable with a pre-amp). This pickup is NOT worth the money. In fact, I'd have returned it if it only cost $10 rather than nearly $100.00.

Do yourself a favor and AVOID THIS PRODUCT. Really bad, and really disappointing from a great company like Taylor. Their guitars deserve SO much better than this.

ac adapter does not produce right voltages. Instead of 1.5 - 12V, it produces 0.3 - 8.6V. Useless junk. Returned . Stay away!!!!

Something somewhere did not make a proper connection, so it didn't provide any power to any of my devices. :-( In the manual, it says that you can order some kind of insert that shrinks the tube a bit, but what a bother! I stopped in at a truck stop when my devices were getting low, and they had a much better option (a 2.1 amp USB connection, a 1.0 amp USB connection, two lighter connection, smaller overall size, slimmer, more stylish looking) for only about $5 more than this one. I bought it, and *gasp* it worked right out of the package! As soon as I finished my road trip, I contacted Amazon to return this thing, and they quickly processed it. I didn't even have to return it. Not that it did me any good to keep it. I ended up throwing it into the recycling bin. What a waste.

Trash sub from a trash company with a sweet emblem. Rated power is wildly exaggerated, recommend using as paperweight or prominent reminder to vet producers of audio equipment BEFORE you buy.

Be wary, this is a great amp but I'm on my 3rd power supply in 4 years.  My working power supply is currently about 17vdc unloaded and 0vac.  I've had two bad ones (once every 2 years) and when they go you see about 12-14vdc and 2.2vac riding on top of the DC voltage.  In my application (in the attic) the temperature is cold in the winter and hot in the summer and this makes this power supply fail a bit faster.  I've seen another reviewer state taking it apart and replacing a capacitor and\or diode will fix the power supply, it's made cheap.

When the power supply fails, sometimes digital tv pictures over-pixelate or just plain black screen.  Internet (cable modem) sees no DNS server and for all purposes the AMP appears as though it is unplugged.

From what I've read here and other places online, the newer version (2900MMA) has the same problem the FT08300 does and uses the same cheap power supply.  I'll probably end up just building my own AC\DC supply from a "known good" supplier someday, but until then, there is a website (MJ Sales) that amazon won't let me link to (since they don't sell it) that has the replacement power supply for 15.99.  It works for 2 years-ish then fails (since it's essentially the same one shipped in the box).  but it may help anyone looking to not drop another 100$ on one of these since replacing the amp may fix the overall problems but replacing your FAILED power supply will much more cheaply fix it's non-functionality.

Read the other 1-2 stars reviews, I'm not the only one who has caught this poorly designed power supply issue. if you're amp isn't working my money is on the poor AC\DC adapter failing you.

While I had high hopes for this product, I was sorely disappointed by performance. The first Power Bank I received showed full bars and took a charge, however it would not charge any of my devices. After contacting the seller and receiving a replacement, ran an experiment (methodology below) and found that I could only get about 7,840mAh or 39.2% of advertised capacity. That's not good! For those who are new to the power bank market, it is normal for power banks to only provide about 60-80% of the advertised capacity, as energy is lost through heat, powering the circuitry,etc. For real-world usage, I performed the following experiment (twice) to test usable capacity:

(1) Deplete my 4,000mAh Galaxy Tab down to 5%
(2) Power Tablet Down
(3) Use Power bank to charge to 100%
(4) Repeat until power bank is drained.

Like I mentioned above, I only got 7,840mAh or 39.2% of advertised capacity. For this reason I would not recommend this product to anyone, as the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Bastex-15-600mAh/dp/B01EIOR0S8/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Bastex 15,600mAh</a>&nbsp;provides more advertised power for slightly more money. Or, if you don't mind investing more in a quality product, Anker tends to make good stuff:&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Anker-20000mAh-Portable-Charger/dp/B00X5RV14Y/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Anker 20000mAh Portable Charger</a>.

Disclaimer: I received this item at a discount in exchange for a fair, honest review (obviously).

P.S. This is a fairly heavy power bank, which would have been ok, had the power bank performed better, but you might want to keep this in mind.

The product pulled such high amperage it would have required a dedicated line and major rewiring effort. It was returned!

This piece of junk immediately fried my subs and went into protection mode when wired at 2 ohms. I replaced a Phoenix Gold amp in this setup. Wiring was exactly the same, except the PG amp was bridged mono at 2 ohms. This thing shorted out with all of the levels set to the lowest settings. I will NEVER buy another Planet Audio product!

It's hard to say whether it's a poorly constructed product or I just expected to much quality for the price, this amp blew very shortly into using it and gave up before my subs (dual l7) I beleive and was told this amp may not be fully one ohm stable to beware of what your needs are. Over all before the Main defect it never got crazy hot and seemed to give decent power to my l7's, it's absolutely massive so definitly pre plan if this can even fit in a accessible spot!

I am quite disappointed in this product.  My Roomba keeps throwing Error # 5 (the charger is not supplying at least 1.25 Amps for more than 30 minutes at a time.)  The plug in charger works fine.  I cleaned all the contacts as the Roomba manual suggested, nada.  Then I plugged my multimeter set to Ahmmeter mode in series with the charging dock and GUESS WHAT!  It seems to wuss out around 1.1 amps and that triggers the Roomba's built in safety to shut off charging after 30 minutes of being under amperage

ALSO the IR system seems REALLY weak and my Roomba cant detect it beyond about a foot and a half (at best).

I highly recommend to NOT buy this, unless you intend to tear it apart and upgrade it like I do.

Minus 4 stars for being CRAP and +1 star for being a half way decent base for me to hack and improve; I only bought it for its parts, otherwise I'd be asking for my money back.

Four years ago, I purchased two Harbor Freight "Thunderbolt" 45-watt solar set-ups (with amorphous thin-film panels) and was tickled pink, but when it was time to put a new roof on our little shed (which has the solar system), we decided to go with something a little newer and a little cleaner. I opted for a 100-watt Renogy monocrystalline solar panel. One panel produced more wattage than six of the Harbor Freight panels.

As part of that upgrade (May 2015), I purchased this Tracer MPPT Tracer2210RN solar controller. I was really dazzled with the "maximum power point tracking" technology, and the bold claims that it'd boost the incoming power by up to 30%.

The trouble started last week, when the red light was illuminated on the front of the controller, indicating a charge problem (low battery). I put a voltmeter on the batteries and found they were down to less than five volts. For lack of a better word, I'll just say it was "shocking" to see the batteries so low.

My smart friends and I did a lot of poking around and came to realize that the solar controller had gone bad. My buddy Milton put this controller on his own solar system and found that OVERNIGHT, it took his batteries down from 13.1v to 5v.

Six months, and it died an ugly death. Because of the way these things are made, there's no repairing them so there went a whole lot of money. I'm really disgusted.

Meanwhile, my Harbor Freight solar equipment (which I gave to a friend) is still performing beautifully.

As other reviewers have said, this Tracer MPPT solar charge controller is just more Chinese junk and garbage.

Very disappointing.

I really wanted to love this amp. I hate loud fans and thought this would be a good choice. This amp put out less power than 75watts RMS per channel at 8 ohms and for that the gain had to be at 100%. I ran the signal into a compressor/limiter to make sure I was getting a peak signal with no distortion and this amp performed like garbage.  Many other people have said there is a problem with this amp and I agree.

THIS IS AN ADDENDUM TO AN EARLIER REVIEW.........SAVE YOUR MONEY AND BUY ANYTHING BUT A PYLE POWER AMP....TODAY ON MY 6TH GIG WITH LESS THAN 20 HOURS (AT ABOUT 2-3 HOURS AT A TIME) IT DIED!!!!!!I DJ ON THE SIDE AS A HOBBY AND THIS AMP MADE ME LOOK BAD......NEVER AGAIN..BUY A PEAVEY, CROWN, QSC OR ANYTHING BUT A PYLE.

Bogus.  Max current for chip far lower. Steppers hate this product.

Just make sure your computer is able to take such a low rating. I've got a laptop that's kind of power hungry, but nothing crazy. The converter not only blew a fuse in my Porsche Boxster, but caused the laptop to become twitchy. Leading me to believe there isn't adequate fault protection inside this unit. The trackpad became jumpy and the windows was lagging horriendously.

I'm giving this a 3 star because it was a la fault on my end for not double checking with my computers specs, but at the same time the lack of an onboard fuse and what seems to be various other safety mechanisms gets this inverter a low review. I would imagine power surges and other electrical current inconsistencies could and probably will fry your attached electronics.
