"StarTech.com USB to Lightning Cable - 2m / 6 ft -Apple MFi Certified - Angled - Black - iPhone Charger Cable - Apple Certified Lightning Cable"I've been using this cable purchased in 5/2017 and in 11/2017. Both are still working fine, BUT I had to take measures to ensure the strain relief portion didn't "break" the cable. I just tested both of these cables, and both are still doing great. I'm posting this review now because I've still NOT been able to find a better cable on Amazon to replace it with(so sad). (and I just now needed to order another one for use in a different area.)My first cable started to separate at the right angle Lightning connector end, at the edge of the strain relief (as many others have already posted).Mine are still doing OK ONLY because I managed to address the flaw in the strain relief.To keep from damaging the connector further, on the first cable, I tried wrapping some electrical tape over the strain relief, and the cable. (I could have used better tape, and it's coming loose and sticky. I'll be taking it off to re-do.) On the second cable, I tried some Silcone tape. (I had some I’d repaired a shower hose with for a while.)https://www.amazon.com/XFasten-Silicone-Fusing-1-Inch-36-Foot/dp/B071NP9L91/ref=sr_1_1?keywords=XFasten+Silicone+Self+Fusing+Tape+1-Inch+x+36-Foot+%28Clear%29&qid=1574571742&s=hi&sr=1-1See the picture. It’s now starting to slip down, and it needs to be re-applied. I think I’ll loop the first wrap around the end of the connector to keep it from slipping down again. It is non-sticky tape, and you apply it by greatly stretching it as you wrap it, and it then “bonds” to itself. I may put a “tie wrap” over the final wrap, since that part seems to come loose.Regarding the cable wiring itself, It tested very well. (or as well as could be expected for the wire gauge used):My USB power source voltage dropped from 5.21V to 4.99V with a 2 amp load on it.My Cable then dropped that voltage down to 4.53V at 1.995Amps, at the end of the cableI can calculate my voltage drop across the cable length: 4.99V minus 4.53V = .46V dropped along the length of the cable.Using Ohms law: R=E/I, (.46V/1.995A) shows total resistance of this cable is 0.230 Ohms (about a quarter of an ohm). (not bad, my 6’6” long StarTech “right-angle Lightning connector” cable is ~ 2 years old and is getting pretty worn)I tested my 2nd Startech 6’ cable and it dropped to 4.54VPer USB hardware spec info:Devices' configuration and low-power functions must operate down to 4.40 V at the hub port by USB 2.0 and that devices' configuration, low-power, and HiGH POWER functions must operate down to 4.00V at the device port (=lightning connector end of the cable) by USB 3.0.Personally, I’d rather not see the voltage drop below 4.5V entering the device plugged into the cable. – so I’m satisfied.-----Here’s some links if you’re interested in what I used to test with:DROK Electronic Loadhttps://www.amazon.com/DROK-Electronic-Adjustable-Intelligent-Temperature/dp/B07FL3PS57/ref=sr_1_1_sspa?keywords=USB+Load+Tester%2C+DROK+Electronic+Load+Test&qid=1574574505&s=hi&sr=1-1-spons&psc=1&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyNlFPWlJBMUQxUjc3JmVuY3J5cHRlZElkPUEwMjkzMTM1M0lCWjkyQ081NEI4UyZlbmNyeXB0ZWRBZElkPUEwMjIyMDE4MVY1U01OQTUzWlRVRiZ3aWRnZXROYW1lPXNwX2F0ZiZhY3Rpb249Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=MakerHawk usb Converter Boardhttps://www.amazon.com/MakerHawk-Converter-Multifunction-Multimeter-Instruments/dp/B07H3NKKBY/ref=sr_1_2?keywords=MakerHawk+7&qid=1574542436&sr=8-2MakerHawk USB 3 meterhttps://www.amazon.com/MakerHawk-3-7-30V-Voltage-Multimeter-Voltmeter/dp/B07FMQZVW2/ref=sr_1_fkmr1_1?keywords=MakerHawk+USB+3+meter&qid=1574574604&s=hi&sr=8-1-fkmr1
