SABRENT[6-Pack 22AWG Premium Micro USB Cables (X3-3ft + X3-1ft) High Speed USB 2.0 A Male to Micro B Sync and Charge Cables [Black] (CB-U631)

I purchased the 1ft cables for 1 reason, charge time, or voltage drop. In comparison to my 6 ft cable, my phone will charge in 1/2 to 1/3 the time, particularly when using a computer to charge the phone. When I use a wall, or car adapter it is not quite 1/3 charge time, more like 2/3 to 1/2 the charge time.Technical Details:With the 1 ft cable, the current has to travel 2 ft, 1 ft to the device, and 1 ft back + distance through the phone. With the larger than standard gauge wire, 22 AWG, it is 0.016 ohms per ft, if I am driving 2 Amps, that is a total voltage drop across the wire of 0.064 V, which means that with a 5 V supply, I am able to deliver 9.872 Watts to the device. On the other hand, for some other cables I own, they are 6 ft long, and 24 AWG, so a smaller wire diameter. If I were to run 2 amps across that wire, which has a total of 0.308 ohms of resistance, then I would have a 0.616 V drop, and see 4.384 V at the device, so 8.768 W. Likewise, the length with affect the inductance and capacitance of the cables. Since phones typically use pulses to charge them, in order to prevent over-charging, you encounter a wave more closely resembling a square wave. Since there is no such thing as a true square wave in real life, due to inductance and capacitance, you would see more of an exponential signal to a DC voltage, then an exponential drop off when the voltage is shut off. This too will become more exaggerated if the cable is longer, causing the signal to more resemble a sinusoidal signal.Since the increased resistance would actually cause the device to see less current as well, because the impedance would essentially slow the flow, the numbers in reality are different. It is sufficient to say that I have seen charge times of approximately 1/2 to 1/3 of what they were previously. As mentioned before, I noticed a significant difference when using a computer to charge the device, and not as significant of a difference when using a wall mounted power supply. The difference is likely due to the power supplies and their supply voltage, the wall supply may compensate for the voltage drop, or run at 0.25 V higher or so, I have not conducted tests on that yet.

Hello Folks! They are a good cord. I broke a couple, trust they good cords. Also I have a lot of usb mini things I recharge. I rely On These Cords !!! Period!!! Thanks!!!

Good value, they work just fine.

I ordered these for use with my Anker PowerPort. (Anker 60W/12A 6-Port USB Charger PowerPort 6 for iPhone 6/6 Plus, iPad Air 2/mini 3, Samsung Galaxy s6/s6 edge, Note 5 and More) I have a several phones, tablets, etc. that needed charging so I set up a charging area with the PowerPort. Strangely, these patch cables would not charge any of my devices using the PowerPort. They work fine if you plug them directly into a wall AC charger, (the ones that come with the device) but not the PowerPort. Don't know what the problem is here, but either the Anker PowerPort or the Sabrent patch cables have a compatibility problem. Since all my other cables work fine with the PowerPort, have to assume it's a Sabrent issue. Learned a lesson here. Order devices and cables from the same manufacturer.Update: I was contacted by Sabrent who offered me replacement jumpers indicating that the original ones shipped were defective. The new jumpers, all though they appear to be identical to the original ones, work just fine with the Anker PowerPort Hub. I am updating my review to a four based on the excellent response to my problem by Sabrent.

I am using these for charging.They work very well and are the fast cordsas they claim to be.I like how many are in this package, thereare 6 and I use them for charging batterypowered cameras to use a extension witha c to micro for charging phones. Also headsetsfor gaming.Yes I would recommend theses cords.

I got these because the cables I was using on my charging base were not working anymore and these worked better than what came with the base. Instead of taking a day or two to charge these cables get it done in a couple of hours.

I needed micro usb cables capable of carrying both data and power. If you haven't noticed, now days a cable may only carry one or the other. If you are using cheap, thin micro-usb cables from 10 years ago, you're bound to have an issue when you expect those cables to be capable of data and power. Do yourself a favor, recycle those puppies. It's time to upgrade! These are thick, well-shielded cables, and the connectors fit very well into the ports.

NICCCCE!I keep wondering why iPhone users keep buying that overhyped, overmarketed, hipster 'crayola' when anyone can take a stroll through aftermarket parts like these and find nothing but stark, sheer, overwhelming....'mess' over in their trash bin of a shopping cart.I recently tried (in vain) to locate similarly-made (in other words, QUALITY-MADE) charging cables like these for my brother and mom's iPhone 4S's, and it was a slap-in-the-face-fest...seriously, who can own one of those...'things' knowing what you'll find in your (real) market for aftermarket parts is a bunch of piecemeal, poorly-made, low-low-LOW quality junk like what I had to end up buying for them. Just terrible.THESE, on the other hand (the Android hand), are HI-GRADE, WELL-MADE, QUALITY little patch cables for your Android charging needs, and that's all there is to it--no junk, no additives, no unnecessary appendages thrown in to ruin the product.They're just perfect--sturdy, compact, well constructed, with the ends looking more like professional cables than many of the finer audio equipment cables I've seen as well (I've seen quite a few).Get these, because you're overdoing it at a base price that's just great...and because, as Android users, we have awesome choices like this rather that the hodge-podge of...erm, manufactured excrement that's flooded that 'other market'.
