ok so I don't know about it having like 10 million+ volts because quite frankly, that seems ridiculous. BUT I have had this tazer flashlight for about 2 years and it is still sparking just as good as it did before, as well as the flashlight. I took it camping a few years with under 40 degree Fahrenheit. Yes I realize that isn't very cold, but it's something. I haven't used it on anyone/anything luckily but im sure it packs a decent punch because the noise alone is threatening
Edit: 9/18/17 well after a few years the tazer has finally died, no longer sparks up. But on the other hand the light still works great

I have my doubts about the claimed output of the USB ports. The impression I got from the product description was that I could get 2.1 amps out of one port, as long as there's no load on the other. Pretty clearly not the case though, since it can't even keep up with the idle load from my phone (Note 4). Not useless as it still works well enough for some other devices that aren't always on, but disappointing.

Lets put this clamping voltage issue to bed. I ordered the BE112230-08 under the pretense that the Belkin website lists the product with a clamping voltage of 330V. When the product came in, the package itself lists 500V. I called Belkin support, who was very fast to give me an answer. They said it's probably a misprint, and their 12-outlets are typically 330V. However, this support agent was reading specs from a database. He could not give me a definitive answer. I flipped the unit itself over. In the plastic itself: L-N 400V L-G 500V N-G 500V.

Long story short - do not order the BE112230-08 if you want top of the line protection. You can spend $5 - $10 more and get 330V from a manufacturer that knows what they're building. It's likely that this is rated so highly because people see a high joule count for low cost, but that doesn't mean you're getting real protection.

As others have mentioned, the stated capacity isn't realistic. Also, both the 12V and 5V outputs sag with current draw. I had hoped to use this to power a retropie box, but get an undervoltage warning when using it. Now I have to try a 12V to 5V converter and use the 12 output. Should work, but more expensive and less efficient than using the included 5V.

From all external appearances as in weight, design, adapters that it takes, it seems fine.  In fact, it seems like it is durable and powerful enough to do exactly what it claimed it can do which is to give 3 to 4 time new charges to your phone.  However, I did read some glitches in the reviews that said that when they plugged it in to their phone and then it charged the phone for about three or four minutes and then it died.

When I opened the package.  It seemed like a very formidable product so I plugged it in and charged it up.  An hour later it wasn't charging my phone anymore, I thought it was the adapter or something and after several attempts to make this work .  It just simply wouldn't.  I remembered the comments that I had read on a few of the reviews about this happening, but I usually blow them off as very rare anomalies.  However, they were right.  For all its good looks.  It just doesn't work sometimes.

However, with that being said, I did take a chance and exchanged it.  I believe it is a very rare manufacturing defect that happens every once in a while.  I certainly think the concept is completely out of this world.  My phone is constantly running out of power and I'm on it every day for every hour.  I just do not have a source of power that makes it run that long so I need something like this.  I hope the next one I get works.

This is nowhere near even 10,000mAh. I took it apart and the 2 individual batteries are labeled 1,000mAh, another longer piece didn't have a label, and there's yet another piece that looks like a battery, because it's wired to the board, but is very strangely bent.
Otherwise, it charges my Samsung galaxy battery once from 25%. My other old 10,000mAh RavPower battery pack holds 3 times as much charge.

I tested to about 30 kV with a 500 Meg load - finally arced over and killed my meter (my fault).  Note you need to apply DC to this - there is an internal oscillator

I had my doubts about this Hub since it only comes with a 3A Power Supply. A 3 amp power supply can't provide enough current to simultaneously power 4 ports at 0.5A per port and 1 Charging Port at 2.4A. The manual even claims the 4 individual ports can supply up to 1.5A.

However, I did a Load Test on the puny little Power Supply and it's tiny little 22 gauge wires.

Testing shows it provides 5.268 volts at No Load. Good sign with the higher voltage.

Compete Test Results:

1A : 5.228 volts
2A : 5.188 volts
3A : 5.147 volts
4A : 5.108 volts

It is rated for 3 amps, so it was amazing to see that it provide a stable 5.1 volts at 4 amps. Got slightly warm at 4 amps.

So, I'm impressed.

I haven't yet tested the USB ports to see how much current they can deliver. Especially simultaneously. But, at this point, I have no reason to doubt the claims.

Consumes a little over a volt.  I hooked it up to a 6 volt battery that I measured was putting out exactly 6 volts, but when I set the VR to max, I could only get 4.98 volts.  However, this is not an issue as my original intent was to connect to a 12 volt battery anyway.  It works well from what I can tell, although it takes a fine hand to dial in the precise voltage you want to have put out.  I secured it with a drop of super glue once I got it dialed in.  I have 4 more to work with.  I gave one to a friend.  Now I need to find 3 more projects to play with.  I'm glad the price is easy on the wallet.

Dies pretty fast despite it's "10000mAh" battery size. I don't believe it is actually 10000 because I only get a little over 2 charges with my iPhone 7 Plus

advertised 20,000 mah and seems like it has that much because of the 10 hours or so it takes to charge it, but won't even charge my tablet thats 4,000 mah twice. Also it takes the outdated mini usb plug but on the plus side it does come with a cool charging wire that willl change into just about any charging interface you could want, but even that's like literally 4 inches long

No way I had more than 1080 joules running through it and it popped... It's not resettable.

It is good..but it does use alot of power. I put it on a variable voltage psu. Well before I had a volt meter I used an actual volt meter with the leads etc..and it was showing 18.2v now with this little panel it shows 16.1 even 15.8v so it is quite the drop in power. As a buyer beware I wouldn't recommend it for small things with low power because it could over all cause problems..how ever it does its job in my case so I am happy with it

It's a bit heavy and bulky, but those aren't big issues for me. The reason for the review is that I have a 3000mAh battery, so I expected this to be able to charge my phone 5 times. In reality, the power bank couldn't even charge it 3 full times, which would put the actual capacity of this battery at <10000mAh, rather than 16750. If I wanted a 10000mAh battery, I'd pay much less.

It does not test 3.0V which is why I bought it. Should have been more clear regarding the limitations. Only tests: 1.5V and 9V. Bummer.

Thought it was a self contained unit with a 120 vac input. My bad.  Its clearly marked 12-16 vdc input, so I bought a 16 volt dc IBM Pad charger for it and unit works great, though the installation looks a little klutzy.

At 3200Mgz my computer requires C17 NOT C16. Also it used 1.53 volts NOT 1.35 volts. However, it did work flawlessly. Hence I still gave it 4 stars. However, this is clearly not high end memory modules considering its latency at C17 and volts of 1.53 at 3200mgz.
